description: We report the development and characterization of a pulsed 243 nm laser that is optimal for the cooling of positronium (Ps). The laser, which is based on the recent chirped pulse-train generator (CPTG) demonstrated by K. Yamada et al. (Phys. Rev. Appl. 16, 014009 (2021)), was designed to output a train of pulses with linewidths of 10 GHz, and with the center frequency of each pulse shifting upward (up-chirped) in time by $4.9\times10^2\,\mathrm{GHz\,μs^{-1}}$. These parameters were determined by the mechanism of chirp cooling, which is the best scheme for cooling many Ps atoms to the recoil temperature of laser cooling. To achieve the designed performance, we drove an optical phase modulator in the CPTG with a deep modulation depth based on the operating principle of the cooling laser. Time-resolved spectroscopic measurements confirmed that the developed laser satisfied the chirp rate and linewidth requirements for efficient chirp cooling. Combined with pulse energy of hundreds of microjoules, we believe that the experimental demonstration of Ps laser cooling has become possible using realistic methods for the generation and velocity measurement of Ps.

description: We investigate atomic chains with different spatial configurations coupled to a ring cavity comprising two counterpropagating traveling modes. We describe the collective atom-light scattering effect with a structure factor of the atomic chain and demonstrate that the interactions between the atoms and the cavity are controlled by the structure factor, resulting in distinctly different collective excitation modes and energy spectrum than for Fabry-Pérot cavities. Remarkably, we observe that a cavity dark mode emerges when the atomic spacings are integer multiples of the half-wavelength. The nodes of this standing-wave dark mode align precisely with the atomic positions, enabling intracavity field conversion without free-space scattering. By adjusting the configuration of the atomic chain, we realize tunable photon routing and a large optical phase shift with almost no photon loss, which can be used to implement versatile building blocks for optical quantum engineering.

description: Uniaxial pressure provides an efficient approach to control the competition between charge density waves (CDWs) and superconductivity in underdoped YBa$_{2}$Cu$_{3}$O$_{\rm{y}}$. It can enhance the correlation volume of ubiquitous short-range 2D CDW correlations, and induces a long-range 3D CDW otherwise only accessible at large magnetic fields. Here, we use x-ray diffraction to study the strain and doping evolution of these CDWs. No signatures of discommensurations nor pair density waves are observed in the investigated strain-temperature parameter space, but direct evidence for a form of competition between 2D and 3D CDWs is uncovered. We show that the interplay between the 3D CDW, the 2D CDWs and superconductivity is qualitatively well described by including strain effects in simulations of a nonlinear sigma model of competing superconducting and CDW orders. From a broader perspective, our results underscore the potential of strain tuning as a powerful tool for probing and manipulating competing orders in quantum materials.

description: The report aims at defining the framework of the counseling service which will be performed by Ernst & Young, one of the 11 partners of CATALISI project. The counseling service will be implemented within the project CATALISI, for the catalysation of institutional transformations of Higher Education Institutions through the adoption of acceleration services. In particular, the report makes reference to the whole process for the fulfilment of the counseling service which is connected to different tasks of the project and whose contributors are 10 partners.

The counseling service, is a task that aims at building ad hoc transformational pathways for each HEI to support the acceleration of institutional transformation and will be designed, implemented and monitored by Ernst & Young (EY). It will be a cross-cutting service that will be available throughout the duration of the project for implementers (HEIs) to access based on their identified needs. The service will cover all the intervention areas and will create a framework to evaluate and collect needs from each HEI. This, will allow EY to better match the demand and the offer of each university involved in the project as beneficiary.Specifically, this task will:- Define the role of the counselor who will act as a bridge between HEIs and experts in specific domains- Design approaches to implement the counseling service on the basis of HEIs needs- Build a framework to guide and support each HEI in pursuing their objectives in the field.

description: We study the space $H(\SO)$ of all homomorphisms of the vector lattice of all slowly oscillating functions on the half-line $\HH=[0,\infty)$. In contrast to the case of homomorphisms of uniformly continuous functions, it is shown that a homomorphism in $H(\SO)$ which maps the unit to zero must be zero-homomorphism. Consequently, we show that the space $H(\SO)$ without zero-homomorphism is homeomorphic to $\HH\times (0, \infty)$. By describing a neighborhood base of zero-homomorphism, we show that $H(\SO)$ is homeomorphic to the space $\HH\times (0, \infty)$ with one point added.

description: Leveraging information across diverse modalities is known to enhance performance on multimodal segmentation tasks. However, effectively fusing information from different modalities remains challenging due to the unique characteristics of each modality. In this paper, we propose a novel fusion strategy that can effectively fuse information from different modality combinations. We also propose a new model named Multi-Modal Segmentation TransFormer (MMSFormer) that incorporates the proposed fusion strategy to perform multimodal material and semantic segmentation tasks. MMSFormer outperforms current state-of-the-art models on three different datasets. As we begin with only one input modality, performance improves progressively as additional modalities are incorporated, showcasing the effectiveness of the fusion block in combining useful information from diverse input modalities. Ablation studies show that different modules in the fusion block are crucial for overall model performance. Furthermore, our ablation studies also highlight the capacity of different input modalities to improve performance in the identification of different types of materials. The code and pretrained models will be made available at https://github.com/csiplab/MMSFormer.

description: No abstracts are to be cited without prior reference to the author.Eighty eight wild cod were in October 1997 tagged with data storage tags placed inside the buccal cavity. The release site was approximately 12 nautical miles north-west of the Faroe Islands at 62°19'N 7°39 .. W (100 m). By August 1999 forty-one (47 %) were recaptured, all from Faroese waters. All cod stayed exclusively in warm (> 5 °C) Atlantic water and usually at shallow (90-130 m) and nearly constant depth (presumably at the bottom) during winter. Vertical migration was rare, but two cod showed _very clear diurnal vertical migration, most likely feeding migration, at exactly the same time of the year. Spawning related activities could in some cases be detected by a change in depth.

description: The fermionic Kitaev chain is a canonical model featuring topological Majorana zero modes. We report the experimental realization of its bosonic analogue in a nano-optomechanical network where parametric interactions induce two-mode squeezing and beamsplitter coupling among the nanomechanical modes, equivalent to hopping and superconductor pairing in the fermionic case, respectively. We observe several extraordinary phenomena in the bosonic dynamics and transport, including quadrature-dependent chiral amplification, exponential scaling of the gain with system size, and strong sensitivity to boundary conditions. Controlling the interaction phases and amplitudes uncovers a rich dynamical phase diagram that links the observed phenomena to non-Hermitian topological phase transitions. Finally, we present an experimental demonstration of an exponentially enhanced response to a small perturbation as a consequence of non-Hermitian topology. These results represent the demonstration of a novel synthetic phase of matter whose bosonic dynamics do not have fermionic parallels, and establish a powerful system to study non-Hermitian topology and its applications in signal manipulation and sensing.

description: No abstracts are to be cited without prior reference to the author.Most Baltic salmon originate in the Gulf ofBothnia region and migrate to the more southerly Main Basin to feed. In 1995-97 we carried out a tagging study of salmon on their spawning migration in the Gulf ofBothnia. In total 1495 salmon were tagged with Carlin tags, data storage tags (DST) or a dummy tag of the DST at coastal sites far off from salmon rivers. In total 414 recoveries have been recorded to date, most of them from the coastal or river fishery. The recovery rate for DST or dummy tags was 38.4% as compared to 20.8% for Carlin tags, mainly due to lower recovery rates of Carlin tagged fish along the coast. DST tags were positively buoyant which increased recovery rate by 21.1 %. Tagged fish migrated northwards at speeds above 20 km/day without evidence of any major differences in speed or behaviour among salmon with Carlin or DST tags. Wild fish did on average migrate 15-19 days earlier than reared fish. Wild fish made up a higher than expected proportion varying in the range of 25-65% at different tagging sites. The exploitation of wild salmon was in the range of 30-100% compared to that of reared salmon. This suggested that recent management measures have been largely successful in reducing the harvest of wild fish.

description: No abstracts are to be cited without prior reference to the author.The Lowestoft Laboratory has been developing electronic data storage tags for use in the study of fish behaviour for more than 10 years. During this time two generations of tag have been developed, each of which has taken advantage of reductions in size and power consumption in microelectronic components. A third generation tag is anticipated in the near future. Our electronic development work has been paralleled with major field programmes that have addressed a variety of ecological and fisheries management problems. Since December 1993 over 600 electronic data storage tags have been deployed on plaice in the North Sea as part of UK government and EC funded research programmes. Over 100 of these tags have been returned, yielding in excess of 14,000 days of data. A number of tags have gathered data for periods in excess of a year. We present detailed information about the behaviour of these fish, how it changes on seasonal time scales, and how it varies in different geographical locations. We go on to describe how this information can be used to reconstruct the spatial movements of individual fish and build a realistic simulation model of the spatial dynamics of the population.

description: Использование в конструкциях почвообрабатывающих рабочих органов интенсификаторов колебаний различных конструкций, за счет создания вибрационного и виброударного режима воздействия, обеспечивает снижение тягового сопротивления на 15-25%. Цель исследований – разработка конструкции и теоретическое обоснование параметров рабочих органов стерневого культиватора с интенсификатором колебаний маятникового типа. Исследования проводили в 2024 г. в ФГБУН «НИИСХ Крыма».

Конструкция рабочего органа стерневого культиватора включает в себя упругую С-образную стойку с размещенными на ее нижнем конце долотом, имеющим зубчатую режущую кромку, режущие крылья и интенсификатор колебаний маятникового типа. Маятниковый ударник включает в себя кронштейн с упругим ограничителем колебаний, рычаг и ударник в виде усеченной сферы, на боковых поверхностях которой размещаются дополнительные грузы в виде пластин (дисков), что обеспечивает возможность регулировки ударной массы в широких пределах. Расположенный над изогнутым рычагом упругий ограничитель колебаний, позволяет регулировать амплитуду колебаний и, таким образом, повысить рабочую частоту ударного воздействия на упругую стойку и рабочий орган.

Используя основные положения теории колебаний и земледельческой механики получена зависимость для определения скорости ударного воздействия рабочего органа на почву, которое должно превышать критическое значение, зависящее от физико-механических свойств почвы.

description: No abstracts are to be cited without prior reference to the author.While tagging procedures are described in details the capture and handling of experimental fish prior to tagging is not given the same attention in most papers. However, traumas that originate from the capture and handling process may for a varying period of time influence the post-release behaviour of the animals studied with Smart-or other electronic tags introducing errors when interpreting the data collected. With emphasis on Atlantic species, the paper gives an overview of capture and handling methods reported in electronic tagging experiments, and where relevant, references are made also to methods used to capture and transport fish for aquarium or other live holding purposes. The advantages and disadvantages of different handling methods are discussed, and a promising new trawl-method for capturing viable individuals of delicate species is summarised.

description: It is assumed in standard cosmology that the Universe underwent a period of inflation in its earliest phase, providing the seeds for structure formation through vacuum fluctuations of the inflaton scalar field. These fluctuations get stretched by the quasi-exponential expansion of the Universe and become squeezed. The aim of this paper is to deepen the understanding of the squeezing process, considering the effect of self-interactions. Axion-like particles can provide a useful setup to study this effect. Specifically we focus on the consequences that a non-trivial evolution of the background axion field has on the squeezing of the perturbations. We follow the evolution of the axion's fluctuation modes from the horizon exit during inflation to the radiation-dominated epoch. We compute Bogoliubov coefficients and squeezing parameters, which are linked to the axion particle number and isocurvature perturbation. We find that the quantum mechanical particle production and the squeezing of the perturbations are enhanced, if one accounts for anharmonic effects, i.e., the effect of higher order terms in the potential. This effect becomes particularly strong towards the hilltop of the potential.

description: Black people and People of Color are disproportionately affected by racism and show increased rates of psychosis. To examine whether racialized migrant groups are particularly exposed to racism and therefore have higher risks for psychosis, this paper (1) systematically assesses rates of psychosis among racialized migrant groups concerning the country of origin, and (2) analyzes interviews regarding the association of racism experiences with psychosis-related symptoms in racialized Black people and People of Color populations in Germany. We present an umbrella review of meta-analyses that report the incidence of positive symptoms (e.g., hallucinations and delusions) and negative symptoms (e.g., apathy and incoherent speech) of diagnosed schizophrenia, other non-affective psychotic disorders (e.g., schizoaffective disorder) or first-episode psychosis among migrants by country of origin. We also report 20 interviews with first- and second-generation migrants racialized as Black and of Color in Germany to capture and classify their experiences of racism as well as racism-associated mental health challenges. In the umbrella review, psychosis risk was greatest when migration occurred from developing countries. Effect size estimates were even larger among Caribbean and African migrants. In the qualitative study, the application of the constant comparative method yielded four subordinate themes that form a subclinical psychosis symptomatology profile related to experiences of racism: (1) a sense of differentness, (2) negative self-awareness, (3) paranoid ideation regarding general persecution, and (4) self-questioning and self-esteem instability. We here provide converging evidence from a quantitative and qualitative analysis that the risk of poor mental health and psychotic experiences is related to racism associated with minority status and migration.

description: The emergence of Fifth-Generation (5G) communication networks has brought forth unprecedented connectivity with ultra-low latency, high data rates, and pervasive coverage. However, meeting the increasing demands of applications for seamless and high-quality communication, especially in rural areas, requires exploring innovative solutions that expand 5G beyond traditional terrestrial networks. Within the context of Non-Terrestrial Networks (NTNs), two promising technologies with vast potential are High Altitude Platforms (HAPs) and satellites. The combination of these two platforms is able to provide wide coverage and reliable communication in remote and inaccessible areas, and/or where terrestrial infrastructure is unavailable. This study evaluates the performance of the communication link between a Geostationary Equatorial Orbit (GEO) satellite and a HAP using the Internet of Drones Simulator (IoD-Sim), implemented in ns-3 and incorporating the 3GPP TR 38.811 channel model. The code base of IoD-Sim is extended to simulate HAPs, accounting for the Earths curvature in various geographic coordinate systems, and considering realistic mobility patterns. A simulation campaign is conducted to evaluate the GEO-to-HAP communication link in terms of Signal-to-Noise Ratio (SNR) in two different scenarios, considering the mobility of the HAP, and as a function of the frequency and the distance.

description: As a promising key technology of 6th generation (6G) mobile communication system, integrated sensing and communication (ISAC) technology aims to make full use of spectrum resources to enable the functional integration of communication and sensing. The ISAC-enabled mobile communication system regularly operate in non-continuous spectrum bands due to crowded licensed frequency bands. However, the conventional sensing algorithms over non-continuous spectrum bands have disadvantages such as reduced peak-to-side lobe ratio (PSLR) and degraded anti-noise performance. Facing this challenge, we propose a high-precision ISAC signal processing algorithm based on compressed sensing (CS) in this paper. By integrating the resource block group (RBG) configuration information in 5th generation new radio (5G NR) and channel information matrices, we can dynamically and accurately obtain power estimation spectra. Moreover, we employ the fast iterative shrinkage-thresholding algorithm (FISTA) to address the reconstruction problem and utilize K-fold cross validation (KCV) to obtain optimal parameters. Simulation results show that the proposed algorithm has lower sidelobes or even zero sidelobes compared with conventional sensing algorithms. Meanwhile, compared with the improved 2D FFT algorithm and conventional 2D FFT algorithm, the proposed algorithms in this paper have a maximum improvement of 54.66 % and 84.36 % in range estimation accuracy, and 41.54 % and 97.09 % in velocity estimation accuracy, respectively.

description: A closed quantum system thermalizes if for time $t \to \infty$, the function ${\rm Tr} (A ρ(t))$ tends asymptotically to ${\rm Tr} (A ρ_{\rm eq})$. Here $A$ is an operator that represents an observable, $ρ(t)$ is the time-dependent density matrix, and $ρ_{\rm eq}$ its equilibrium value. We investigate thermalization of a chaotic many-body quantum system by combining the Hartree-Fock (HF) approach and the Bohigas-Giannoni-Schmit (BGS) conjecture. The HF Hamiltonian defines an integrable system and the gross fatures of the spectrum. The residual interaction locally mixes the HF eigenstates. The BGS conjecture implies that the statistics of the resulting eigenvalues and eigenfunctions agrees with random-matrix predictions. In that way, the Hamiltonian $H$ of the system acquires statistical features. The agreement of the statistics with random-matrix properties is local, i.e, confined to an interval $Δ$ (the correlation width). With $ρ(t) = \exp \{ - i t H / \hbar \} ρ(0) \exp \{ i H t / \hbar \}$, the statistical properties of $H$ define the statistical properties of ${\rm Tr} (A ρ(t))$. Using these we show that in the semiclassical regime, ${\rm Tr} (A ρ(t))$ decays with time scale $\hbar / Δ$ towards an asymptotic value. If the energy spread of the system is of order $Δ$, that value corresponds to statistical equilibrium.
 The correlation width $Δ$ is the central parameter of our approach. It defines the interval within which the spectral fluctuations agree with random-matrix predictions. It defines the maximum energy spread of the system that permits thermalization. And it defines the time scale $\hbar / Δ$ within which ${\rm Tr}(A ρ(t))$ approaches the value ${\rm Tr}(A ρ_{\rm eq})$.

description: No abstracts are to be cited without prior reference to the author.Temperature data storage tags were applied to maturing chum salmon in the Bering Sea during the summer of 1998, which resulted in the recovery of five tags in coastal waters around Japan. These tags recorded water temperature experienced by the fish for periods of 62 to 117 days at resolutions of 15 to 30 minutes. The time series of temperatures show that the fish engaged in diurnal diving patterns as they migrated to home rivers. Nighttime temperatures were nearly constant or showed slight cooling trends during the course of the night and were typically the highest temperatures experienced by the fish each day. During the day, temperatures often showed dramatic changes as the fish changed depth. We analyzed differenced series of sunrise and sunset temperatures recorded for the fish as an indication of progress against horizontal thermal gradients, which were assumed to represent changes in latitudinal position. Daytime differences were positive when the fish were migrating to warmer waters; whereas, nighttime differences were zero or slightly negative. This suggests that the fish make more progress in their migration during the day than at night. Migrations into cooler waters were more difficult to interpret, perhaps owing to the fact they occurred later in the migration when fish may have been entering coastal areas. These data support the hypothesis that orientation cues associated with sun position may play a significant role in oceanic movements of chum salmon.

description: No abstracts are to be cited without prior reference to the author.Fifty-five data storage tags that record temperature data were placed externally on five species of Pacific salmonids (0ncorhynchus spp.) in the North Pacific Ocean and Bering Sea during three research cruises from May to July in 1998. Eight temperature-recording data storage tags were recovered from three salmonids in Alaska (pink [ 0. gorbuscha] and coho [ 0. kisutch] salmon and steelhead trout [ 0. mykiss]) and five chum ( 0. keta) salmon in Japan after 21-117 days. Data intervals ranged from 7.5 to 30 minutes. These tags contain the first long-term records of ambient temperature from Pacific salmonids migrating at sea. Temperature data imply die! patterns of descents to deeper, cooler water and ascents to the surface. Fish were found at higher average temperatures at night, with narrower temperature ranges and fewer descents than during the day. Fish tagged in the Gulf of Alaska were at higher temperatures on average (10°- 12°C) than chum salmon tagged in the Bering Sea (8°-10°C). Chum salmon were also found at a wider range of temperatures (-1 °-22°C vs. 5°-15° C). This is probably related both to the different oceanographic regions through which the fish migrated, as well as species differences in thermal range and vertical movements. Proportions of time that individual fish spent at different temperatures seemed to vary among oceanographic regions. Steelhead trout may descend to moderate depths (50 m) and not be limited to the top few meters, as had been believed. Japanese chum salmon may seek deep, cold waters as they encounter warm surface temperatures on their homeward migrations. Temperature data from all fish showed an initial period (4-21 days) of day and night temperatures near those of sea surface temperatures, suggesting a period of recuperation from tagging trauma. A period of tagging recuperation suggests that vertical movement data from short-term ultrasonic telemetry studies may not represent normal behavior of fish. The considerable diurnal and shorter-term variation in ambient temperatures suggests that offshore ocean distribution may be linked more to prey distribution and foraging than to sea surface temperatures.

description: No abstracts are to be cited without prior reference to the author.Migrations play a key role in the life history of the spider crab Maia squinodo and determine fishery catches. These movements involve an important bothymetric gradient and a change in the oceanographic environment. Ultrasonic telemetry has o number of drawbacks in the study of migrations stemming from the difficulty in the continuous tracking of crabs moving to deep offshore waters. The recent introduction of electronic data storage or archival tags allows for the continuous monitoring of depth and temperature in the inmediate habitat of the crabs, and for the reconstruction of the movement patterns using baseline data on habitat characteristics. This study was carried out on the Galician coast (NW Spain) for the calibration and use of electronic togs as a tool to study the migrations of the spider crab. In the summer of 1996, crabs were tagged with both ultrasonic transmitters and electronic tags for temperature and depth.Tracking was carried out discontinuously, at intervals of approximately l week, in order to locate the individuals with telemetry. Our results show a recapture rate of approx. 70% and the information provided by telemetry and electronic tags point ta autumn migrations along bothymetric gradients (from areas of < l O m deep to zones of up to l 00 m) in short periods of time (mean=5.7 days, range= 1.3 - 13.6 days). During these movements crabs travel through environments characterized by different temperatures and substrates. The available data on the bathymetry and oceanography of the study area and the records of the electronic togs could make it possible to reconstruct the tracks of the tagged individuals.

description: Деградация почв является серьёзной экологической проблемой, которая негативно влияет на сельское хозяйство и окружающую среду. Засоление почв снижает их плодородие, что приводит к уменьшению урожайности и ухудшению условий для агропромышленного комплекса.  Целью данного исследования является оценка влияния капельного орошения на засоленные земли полупустынной зоны. Задачи исследования: анализ научных литературных источников по изучаемой тематике, проведение полевых выездов с целью визуального осмотра водных объектов, отбора проб оросительной и сбросной воды, а так же почвы с сельскохозяйственных полей на территории Калмыцко-Астраханской рисовой оросительной системы (КАРОС), для дальнейшего проведения химического лабораторного анализа. При проведении исследований в Астраханской области с 12.07-14.07.2023г. было установлено, что КАРОС не функционирует в проектном режиме. Воды системы в основном используются для капельного орошения с целью выращивания овощных, зерновых и бахчевых культур. Преимущества использования метода капельного орошения заключается в том, что вода подается в почву вблизи максимально развитой корневой системы растений, что способствует эффективному увлажнению почвы. 

Малые поливные нормы позволяют не только сохранить водные запасы, но и не допустить возможный вынос вредных веществ с дренажными стоками обратно в поверхностные или подземные источники. Экологическая эффективность капельного орошения играет важную роль в предотвращении деградации земель и сохранения их плодородия.  Исходя из результатов химического анализа проб почвы, видно, что значительно превышены показатели хлора (133 мг/кг при ПДК 10 мг/кг), натрия (67 мг/кг при ПДК 12-15 мг/кг), аммония (2,68 мг/кг при ПДК 0,1 мг/кг), а также водородного показателя (7,1 мг/кг при ПДК 5,5-7). Минерализация оросительной воды 0,8 г/л, что находится в пределах оросительной нормы (1 г/л). Результат химического анализа оросительной и сбросной воды показал превышение ионов Na+, HCO3-. Экологическая эффективность капельного орошения играет важную роль в предотвращении деградации земель и сохранения их плодородия.

Данный метод способствует уменьшению испарения воды, предотвращению эрозии почвы и улучшению качества почвенного покрова. Кроме того, капельное орошение способствует сокращению использования химических удобрений и пестицидов, так как позволяет точно дозировать необходимые ресурсы, что снижает негативное воздействие на окружающую среду.

description: Two series of unsymmetrical hybrid benzoxazines were separately synthesized using combinations of natural bio-phenolic materials, namely cardanol (C) with eugenol (E), vanillin (V), and guaiacol (G) using diaminodiphenylmethane (ddm)/diaminodiphenyl ether (dde) through the well-known Mannich reaction. The synthesized hybrid benzoxazines have a cure temperature between 229 °C and 269 °C. Compared to previous synthesized benzoxazines, vanillin-based benzoxazines (C-dde-V and C-ddm-V) have a lower cure temperature. TGA results show that poly(C-ddm-V) and poly(C-dde-V), two hybrid polybenzoxazines, have superior thermal stability than the other hybrid polybenzoxazines. In order to develop polybenzoxazine composites, different wt% of GPTMS functionalized vermiculite was incorporated with poly(C-ddm-V). The properties of these composites were examined and contrasted with those of a neat matrix. The hybrid polybenzoxazines and composites water contact angle values vary from 136° to 144°, suggesting that all of the hybrid polybenzoxazines and composites have good hydrophobic behavior. On increasing the concentration of vermiculite, the dielectric constant value significantly decreased to a low dielectric constant.

description: No abstracts are to be cited without prior reference to the author.Biotelemetry is a powerful tool for monitoring aquatic species m their natural environment, from a passive perspective, without the biases associated with conventional sampling and monitoring techniques. Advances in telemetry are necessary to monitor aquatic species in remote environments, with vast stretches of water, and in situations requiring both acoustic and radio transmissions (e.g. for diadromous fish). In this paper, a system is described, based upon a field proven radio telemetry receiver, and incorporating combined acoustic and radio smart transmitters, wireless hydrophones and two-way satelite communications. The system was first deployed within Bay d'Espoir, NF, Canada, to determine whether aquaculture raised steelhead trout (Oncorhynchus mykiss) (1.5-2.0 kg), experimentally released in the vicinity of a commercial aquaculture site, remained at the site (site fidelity) or dispersed from it. Two sets of fish releases, summer and winter 1998, were performed to determine seasonal effects on movement of aquaculture raised steelhead trout in the wild. Results suggested strong site fidelity among steelhead trout when released during the growing season (summer). Less fidelity was displayed for the winter released steelhead with a higher degree of dispersal during this season.
