Maternal and child health is one of the priority aspects to consider. Based on the results of the 2012 Indonesian Demographic and Health Survey (IDHS), it was shown that the neonates mortality rate in 2012 was 19 per 1000 live births. This problem arises in part related to the problem of breastfeeding. The results of the screening for the nutritional status of toddlers at the posyandu showed that as many as 11 toddlers were malnourished, this was due to the low knowledge of mothers regarding the balanced nutrition of toddlers, poor attitudes in fulfilling balanced nutrition for toddlers, and poor culture in fulfilling toddler nutrition. The main target of this program is assistance for the formation and training of Breastfeeding Mothers' Groups in an effort to improve the health status of mothers, babies and toddlers in Penyengat Olak Village, Kec. Jambi Outside the City. The output of this program is there is an increase in community participation in improving the health of mothers and children by assisting the formation of groups of breastfeeding mothers. The implementation of the activity was started with an observation of the breastfeeding mothers research group in several Penyengat Olak village which consisted of 3 breastfeeding mothers' groups, namely in the RT. 18, RT 19, and RT 20. Each group consists of 10 people consisting of pregnant women and nursing mothers. It is hoped that the continuity of breastfeeding mother's breastfeeding program can be maintained, even though there are many factors raised by members, such as being busy taking care of the house and children, inappropriate meeting times, long distances, and so on.

Published: January 2021

This study was carried out to analyse cassava production, prospects and challenges in Irepodun local government area, Kwara State, Nigeria. It aimed to examine the determinant variables and determine the profitability level of cassava enterprises. The study was based on primary data obtained with the aid of structured questionnaire from 100 cassava farmers drawn through multi-stage sampling techniques from the study area. Data were analysed using descriptive statistics, ordinary least square (OLS) regression model and gross margin analysis. The result of the OLS regression estimates showed that farm size, cost of fertilizer application, farm size, herbicides, family and hired labour were significant variable affecting cassava production in the study area. Fertilizer, farm size and hired labour are significant at 1% while herbicide and family labour are significant at 10%. The study found that the average gross margin per hectare for cassava production in the study area was ₦24,749.28 ($65.30) with a gross benefit ratio of 1.38. This shows that for every ₦1 invested in the business of cassava production, there is a corresponding profit of ₦1.38. The major challenges identified in cassava enterprise are huge transportation cost, high cost of production, lack of improved cassava cultivars, and lack of market linkages. The study concluded despite the problem encountered in the study area, cassava production is profitable and can serve as a panacea for economic improvement of households. Therefore, the study recommends that basic inputs such as improved cassava varieties, herbicides and fertilizer should be made available at affordable price. Also, infrastructural facilities such as good road network and improve marketing channels should be provided in order to sustain current cassava production rate and economic gains from the production.

Das Werk als Entgrenzung. : Werkkomplex und Dynamik des Gesamtwerks

Published: January 2021

Abstract Im Kontext des neu aufgekommenen theoretischen Interesses für die Werkkategorie wird überwiegend das ,Einzelwerk‘ fokussiert. Im vorliegenden Aufsatz wird das heuristische Potenzial des Konzepts ,Gesamtwerk‘ als ein anderer Teil der Werkkategorie
herausgearbeitet. Neben dem üblichen Aspekt eines ,Lebenswerks‘ schließt das Gesamtwerk vielfältige Werkkomplexe und Werkgruppierungen ein, die auf Produktions- oder Rezeptionsseite entstehen. Analysiert werden feste und variable Anordnungen, Ab- und Entgrenzungen zwischen
Einzelwerken eines Autors, die das Gesamtwerk zu einem dynamischen Gefüge machen. Ein Werkkomplex bildet eine Zwischenstufe und ein Bindeglied zwischen ,Einzelwerk‘ und ,Gesamtwerk‘. Daher besitzt er eine besondere Relevanz für die semantische Zusammensetzung der Werkkategorie
als Trias, deren Teile sich aufeinander beziehen: Opus – Werkkomplex – Œuvre.The newly arisen theoretical research on the literary work category focuses mainly on the ,single work‘. This paper argues for the heuristic potential of the ,oeuvre‘ as another part
of the work category. In addition to the usual aspect of a ,life’s work‘, the oeuvre includes diverse work complexes and work groupings that emerge on the production or reception side. The paper analyzes a dynamic structure of the oeuvre: fixed and variable arrangements, boundaries
and dissolution of borders between single works by the same author. A work complex forms an intermediate stage and a link between ,single work‘ and ,oeuvre‘. It therefore has a special relevance for the semantic composition of the work category as a triad, the parts of which refer
to each other: single work – work complex – oeuvre.
Funktionen unzuverlässigen Erzählens in der deutschsprachigen Gegenwartsliteratur.
Authors: Bartsch Annika
Published: January 2021

In Sibylle Lewitscharoffs Roman Blumenberg (2011) finden sich Kommentare, die explizit auf die Unzuverlässigkeit des Erzählers verweisen. Ein ,,Kurzes Zwischenstück“2 unterbricht die eigentliche Erzählung. Es thematisiert das Erzählen,
genauer: den Erzähler selbst, und fragt danach, wo seine Zuständigkeit und damit Zuverlässigkeit endet. Eine solche metanarrative Überlegung wirkt sich nicht nur unmittelbar auf das Erzählte vor und nach dem eingefügten ,,Zwischenstück“ aus, sondern
sie richtet auch den Fokus auf ein Erzählverfahren, das Konjunktur in der Gegenwartsliteratur zu haben scheint. Denn Blumenberg ist kein Einzelfall. Es finden sich zahlreiche Texte, in denen wie in Lewitscharoffs Roman offen unzuverlässig erzählt wird. Darüber hinaus
gibt es einige Fälle von täuschend unzuverlässigem Erzählen, die also ihren ,,Lesern (vorübergehend) gute Grunde für falsche Annahmen über fiktive Tatsachen“ geben.3 Weniger häufig scheinen in der Gegenwartsliteratur axiologisch unzuverlässig
erzählte Texte vorzukommen, in denen die Werte des Erzählers nicht mit den Werten des Textes übereinstimmen.4

Silvia Bovenschen (1946-2017) hat in den achtziger Jahren des 20. Jahrhunderts mit ihrer – feministisch inspirierten – Dissertation Die imaginierte Weiblichkeit (1979)1 in der Literaturwissenschaft viel Resonanz gefunden. ,,Sehr verkürzt gesagt“,
so Bovenschen in einem Interview, werden in der Arbeit ,,die reichen poetischen Bildvorstellungen der Weiblichkeit kontrastiert mit der Marginalisierung der realen Frauen in den Überlieferungen“.2 Der Untertitel, der zuerst einmal die ,,kulturgeschichtlichen“ und
dann auch die ,,literarischen Präsentationsformen des Weiblichen“ anführt, signalisiert eine kulturwissenschaftliche Orientierung der Beschäftigung mit literaturwissenschaftlichen Gegenständen – jenseits der bloßen Textinterpretation. Das gilt auch für
weitere Publikationen der Autorin und der Herausgeberin Bovenschen, in denen es zum Beispiel um ,,Mode“3 oder um ,,Freundschaft“4 geht oder auch um ,,Rituale des Alltags“5 und in denen die literarischen Bezüge unter Umständen sehr
zurücktreten.
The Correlation of Platelet Lymphocyte Ratio (PLR) as 28 Days Sepsis Mortality Predictor in Intensive Care Unit RSMH Palembang
Authors: Tiara Shanty
Published: January 2021

Introduction. Inflammatory and anti-inflammatory response are important in pathophysiology and mortality of sepsis. Platelet as first line inflammatory marker was found increasing during early phase of infection. Decrease in lymphocyte was caused by disrupted balance between inflammatory and anti-inflammatory response. Platelet-to-lymphocyte ratio (PLR) is a cheap and accessible biomarker of sepsis mortality. This study aims to find the sensitivity and specificity of PLR as mortality predictor of sepsis in 28 days.

Method. This observational analytic study with retrospective cohort design was conducted to 91 sepsis patients in intensive care unit of Dr. Mohammad Hoesin Palembang Central Hospital between January and December 2019. Samples were secondarily collected from medical record during June-July 2020. Data was analyzed using chi-square test, cog regression test, and ROC curve analysis.

Results. The result found 50 patients (54,9%) died in 28 days. Morbidity score (Charlson) was the only statistically significant mortality parameter (p=0,009). The study reported PLR cut-off point of >272,22. The sensitivity and specificity of PLR as 28-days sepsis mortality predictor are 84% and 80,49% respectively.

Conclusion. PLR is alternatively reliable mortality predictor in sepsis patient, accounted to its relatively high sensitivity and specificity.
Characteristics of the arribazones of the Kemp’s ridley in Rancho Nuevo (Tamaulipas, México)

Published: January 2021

The Kemp's ridley females (Lepidochelys kempi, Garman 1880) nest in massive events knownas arribazones. In this paper some characteristics of the arribazones are described. A group of 132 females tagged was followed throughout some nesting seasons to determine their preference to nest in arribazones; the most of them were observed at least 50% of times forming these groups. The nesting seasons (1978- 1998) were classified according to the percent of females that nested in these groups; five years were classified as "without" arribazones, because less than 50% of the turtles nested in these events; the beginning of these seasons was delayed and the abundance of nesting was lower than that of the precedingyear. Arribazones were more frequent in May and they were correlated with the population abundance (p<0.05), in contrast, they were weakly related with the length of nesting seasons. Arribazones occur approximately at the same time throughout the 100 km length of the nesting beach; this suggests that some environmental factor of synoptic scale contributes to regulate this behavior.

Early study on vertical distribution of zooplankton biovolume in Bahia Magdalena, Baja California Sur, Mexico.
Authors: Hernández-Trujillo S. , Zárate-Villa A. , Esqueda-Escárcega G. Ma.
Published: January 2021

Zooplankton abundance distribution between 5 m and 25 m of depth was measured using an opening and closing multi-net sampler in July and December 1998, and March 1999; three sampling stations were surveyed along a transect traced perpendicularly to the coastline (inside, mouth and offshore). In July the highest average of abundance was inside the bay at 5 m, and the minimum in the offshore station at 25 m. In December the highest average of zooplankton abundance was recorded in the mouth of the bay at 10 m-depth and the lowest in the offshore stations at the same depth. In March the highest average biovolume of zooplankton was found in the mouth of the bay at 25 m-depth, and the lower inside the bay at 20 m-depth. The three-way analysis of variance showed differences between months (p<0,05), sampling depths, and between the sampling stations. Non-significant differences in the abundance of biovolume suggest a continuous mixing process produced by the outside-inside exchange of water along the year.

Authors: Valério-Berardo M.  T. , Flynn M. N. , Rodrí­gues L. M. R. , Attollini F. S.
Published: January 2021

Macrobenthos distribution along the salinity gradient and the pattern of species temporal changes were investigated in the Itanhaém River Estuary. Environmental variables such as grain size, sediment organic content, water salinity, water temperature and dissolved oxygen were examined as factors likely to influence the distribution of species. A total of 2130 individuals, distributed in 16 taxa (species/genera) were collected from the 12 samples obtained. The most abundant species were Cyprideis salebrosa, Heteromastus similis, Scololepsis squamata, Nephtys squamosa, Diplodonta sp. and Tellina sp. The canonical ordinations analysis indicated the presence of three benthic associations: a marine Diplodonta sp. - Tellina sp. community; a brackish water C. salebrosa - N. squamosa community and a wide spread S. squamata - H. similis community. The distribution of the estuarine macrozoobenthic species seems to be mainly controlled by salinity and the observed gradient in species compositon and dominance in the marine and brackish part of the Itanhaém River Estuary is similar to the one occurring in other mixohaline habitats of the Brazilian Southeastern Coast.

Published: January 2021

The species composition of epiphytic diatom assemblages found on different taxa of subtropical macroalgae was determined. Samplings were carried out in a macroalgae bed located in Punta Roca Caimancito beach, B. C. S. in june and december 2001, and on april, may and july 2002, collecting the most frequent macroalgae taxa. The most conspicuous out of twelve macroalgae taxa were: Hydroclathrus clathrathus, Laurencia pacifica, L. johnstonii, Padina mexicana and P. caulescens. A total of 278 diatom taxa were recorded. This is the largest species richness recorded for this type of substrate, and out of which 44 are new records for the region. Out of 75 genera recognized the best represented were: Mastogloia (25 species), Amphora (23), Navicula (23), Nitzschia (22), Cocconeis (22), Lyrella (12) and Achnanthes (11). The most abundant taxa were Cocconeis disculus and C. dirupta. The number of diatom taxa permacroalgae species was also high, ranging from 89 (Codium spp.) to 143 (L. pacifica). Albeit, this differencecould be attributed to the number of specimens collected per macroalga species.

Published: January 2021

Plankton samples collected from Bahía de La Paz, Baja California Sur, Mexico in June 2008 revealed infection of copepods by Blastodinium spp. Of eight copepod genera encountered in the samples, only one (Paracalanus) was parasitized by Blastodinium. Infection prevalence was low, 0.6 % to 2.0 %, withall parasitized individuals being females tentatively identified as Paracalanus parvus. All but one infected host examined during the study was parasitized by Blastodinium crassum, the sole exception being a Paracalanus cf. parvus infected by Blastodinium contortum. A phylogeny constructed using a dataset of ~1.3 Kb sequences of the small subunit ribosomal DNA gene of B. contortum and B. crassum from Bahía de La Paz and 36 other dinoflagellate sequences available in GenBank, including all available for Blastodinium,placed Blastodinium as a monophyletic clade deep within the Dinokaryota. Sequence divergence among B. contortum ex Paracalanus cf. parvus from Bahía de La Paz, B. contortum ex P. parvus from the Mediterranean Sea, B. contortum ex Clausocalanus arcuicornis, B. crassum ex P. cf. parvus from Bahía de La Paz, and B. navicula ex Corycaeus giesbrechti supported separation of the three parasites as distinct species.

An individual is reported Euphausiid Thysanoessa spinifera Holmes 1900 with singular morphology, collected in the Oregon coast, USA (June 2001). This is a juvenile with a marked variation of the morphology originally described for juveniles and adults, given the absence of a face and the presence of a small keel directed towards forward on top of the carapace. The difference between the variability is defined intraspecific morphological at (1) population level (ecophenotype) and (2) individual variability as part of a natural gradient of the morphology of the organisms of the same population. It is considered unlikely that this specimen is a new species of euphausiid; It is proposed that it is an extreme case of individual variability of T. spinifera or a hybrid of T. spinifera and Euphausia pacifica.

Authors: Siqueiros -Beltrones D. A. , Argumedo -Hernández U.
Published: January 2021

This is the first record of an epiphytic diatom assemblage of Ploclamium cartilagineum. Fifteenyears ago observations on a specimen of P. cartilagineum revealed that large diatom of certain taxa occurred abundantly on its branches, and suggested also that it may harbor a particular diatom assemblage. Thus, we set out objective into identifying all the diatom taxa in the assemblage represented on the same P. cartilagineumspecimen, and to determine their proportional abundances. Overall 46 taxa of epiphytic diatoms were identified. The diatom assemblage was characterized by abundant large forms such as Gephyria media, and Hyalodiscus punctatus a new record for the region, and the small form Cocconeis californica. Also include is, Grammatophora macilenta a new record for the region. Hitherto rare taxa in the region were very common such as Rhabdonema adriaticum, Campylopyxys garkeana, and Melosira polaris/Melosira sol. Although the estimated species richness and diversity values are high as in other assemblages of benthic diatoms, its basic structure (floristics) in which large forms rival the smaller forms in number, makes this assemblage particular.
Macrobenthic communities in a temperate urban estuary of high dominance and low diversity: Montevideo Bay (Uruguay).
Authors: Muniz P. , Venturini N.
Published: January 2021

The macrobenthic subtidal community was studied between April 1997 and April 1998 in Montevideo bay, an urban estuary located in the fluvio marine system of the Río de la Plata (Uruguay) that receives a variety of industrial and sewage inputs. Monthly surveys were carried out at ten sampling stations where sediment samples were taken with a manual corer and analysed for granulometric parameters, organic matter content, chlorophyll a and phaeopigments content, redox potential, and macrobenthic fauna. The area presented high organic matter content in its sediments and several regions of the bottom were anoxic during a large part of the sampling period. The benthic macrofauna was dominated, both in numbers as well as in biomass, by the small surface deposit-feeder gastropod Heleobia cf. australis. Cluster analysis, Multidimensional Scaling and Canonical Correspondence Analysis revealed that the study area could be divided in two well-defined regions with different environmental characteristics and different faunal composition. The dissolved oxygen content in the bottom water and variables related to it were the most important factors in explaining the patterns of the benthic communities. At the phylum level, the meta-analysis of “production” showed a high disturbance status for all stations. The innerregion, the most affected by anthropogenic   activities, was the most compromised  environmentally and biologically, and was  characterised by a very low diversity and  abundance, reduced conditions in the sediments and low oxygenated bottom water. In more external places of the bay, on the other hand, perhaps due to their location at a greater distance from the sources of organic material and in a region with higher hydrodynamic energy, the conditions for the development of benthic fauna were more favourable. Spatial and temporal faunistic patterns observed and their possible causes are analysed and discussed in relation to the natural and anthropogenic factors that act in this coastal ecosystem.

Cabraaremorica is reported for the first time after the original description. However, these records should be considered cautiously because the distinction between Cabra aremorica and C. reticulata is difficult based on routine light microscopy observations. It is uncertain whether there is a high intraspecific morphological variability or severalco-occurring undescribed species. Cabra levis, a species recently described, is reported for first time beyond the type locality.

Benthic diatoms collected with a Technicap model PPS-3/3 trap with an aperture of 0.125 m2 were recorded, which consists of a programmable carousel motorized with twelve 250 mL bottles installed at 300 m deep in Cuenca Alfonso, Bahía de La Paz. The hypothesis that diatoms deposited in the trap sediment would be related to mangrove environments from the Bay of La Paz. Thus, in order to identify the benthic diatoms and infer their origin, a sample for the period December 2011 to January 2012. The identification was made from images taken with a Zeiss Supra Vp55 scanning electron microscope. I know identified 38 diatom taxa, 32 of which were benthic forms including the species: Actinoptychus vulgaris, Halamphora coffeaeformis, Delphineis surirella, Fragilariopsis doliolus and Nitzschia amabilis. What these, the observed diatoms correspond mainly to benthic taxa commonly represented in habitats of shallow intertidal and subtidal zones. Although the hypo- thesis was supported, the species composition of diatoms it did not allow greater precision on the environment of origin.

Microalgae are commonly used as food source in aquaculture, mainly for shellfish and larvae ofcrustacean and fish. All hatcheries need an excellent inoculum to produce high-quality microalgae when cultured outdoor in extensive systems, and this depends largely on the health of the microalgae cultured under laboratory  conditions as a primary step. Therefore, the aim of this work was to assess variations of dry weight, carbon, C/N ratio, hydrogen and chlorophylls as physiological indicators of nutrients uptake and growth rate during exponential growth of Isochrysis galbana, Chaetoceros calcitrans and Dunaliella tertiolecta, using f/2 as culture medium.Chaetoceros calcitrans and D. tertiolecta had higher carbon content (~30 pg cell-1). The C/N ratio varied widely, gradually decreasing on I. galbana. Chlorophyll a varied among the three microalgae tested, ranging from <0.05 to >0.25 pg cell-1. Growth rate was higher in I. galbana (K’ 0.83) followed by D. tertiolecta and C. calcitrans. Results showed that nutrient incorporation by cell change when cell density increases; this information providesnew insights in the physiology of marine microalgae and confirms that nutrient uptake dynamics is different in each microalga species. Finally, this study indicates that using one culture medium is not equally efficient for all microalgae used in aquaculture since each species has specific nutritional requirements.

We describe the size frequency distribution, sex ratio and weight-length relationship of the IndoPacific sailfish Istiophorus platypterus off the coast of Mazatlan, Sinaloa, Gulf of California. Data were collected from the sports fishery during several sampling periods from 2002 to 2009. A total of 354 Sailfish were sampled, including 185 females, 161 males and 8 of unknown sex. Total weight (TW) varied from 14 to 41 kg, and sizesranged between 128 and 195 cm postorbital length (PL), with significant differences between the sexes (P < 0.05). The sex ratio throughout the period analyzed was 0.87: 1 (M:H). The total length (TL) and postorbital length (LPO) of organisms were related through the linear fit model for both sexes TL = 57.204 + 1.15 x LPO (r2 = 0.65). There were no significant differences in the weight-length relationship between the sexes (ANCOVA, P>0.05).The general equation relating weight and length for both sexes was TW = 0.0009 x PL2.009. The value of the slope b was significantly different from 3, indicating negative allometric growth (t, P < 0.05). Indo-Pacific sailfish exploitation is currently limited to the sports-recreational fishery; however, there are initiatives to promote the commercial exploitation of this resource. Therefore, results derived from this study are of importance, since they providebasic information on the biology of this species, and can serve as a baseline for the management of this resource.
Feeding behaviour of the Pacific red snapper Lutjanus peru (Nichols & Murphy, 1922) (Percoidei: Lutjanidae) larvae at the onset of exogenous feeding.
Authors: Peña Renato , Dumas Silvie
Published: January 2021

The behaviour of the Pacific red snapper Lutjanus peru larvae during the onset of exogenous feeding at day 3 after hatching at 26º C was studied. Ten larvae were directly observed during 5 min each before and after the addition of feed. Rotifers (Brachionus rotundiformis) and copepod nauplii (Euterpina acutifrons) were used as live feed at a density of 5 prey/ml. Larval behavior was described before and after prey addition. Also, the number of larvae that displayed an attack posture and the number of attacks per larvae during the observationperiod were recorded. Before prey addition, the larvae displayed three types of conduct: swimming, resting and fast impulse. This behavioral pattern changed with the presence of feed, regardless of prey type. The swimming conduct increased duration but changed to a short distance and frequent pauses. The resting conduct reduced itsduration and two new modal action patterns associated to feeding were present: “S” posture after prey detection and the attack which consisted in a direct larval strike towards the prey and may include prey capture. Less than 50% of the observed larvae displayed the attack posture and the mean number of attacks per larvae was less than 1.5 during the observation period regardless of prey type. Results are similar to the reported for other species during the onset of exogenous feeding and suggest that copepod nauplii may be a more suitable prey during first feeding of L. peru.

Prospective floristics of epiphytic diatoms on Rhodophyta from the Southern Gulf of Mexico
Authors: Siqueiros Beltrones David Alfaro , Martí­nez - Hernández Yuriko Joscelin
Published: January 2021

Studies on epiphytic diatoms can be considered somewhat lacking worldwide, mainly because of the enormous scientific research potential around them, and there is still much to do concerning floristics alone. Particularly for the Mexican coasts, mainly in the southern Gulf of Mexico. Thus, our objective was to determine the epiphytic diatom floristics for several species of Rhodophyta from the coast of Veracruz state (México). Diatoms sampled from specimens of six taxa of Rhodophyta were observed in permanent mountings, under light microscopy. A total 115 diatom taxa were identified, that support our expectancy of a potential species richness much higher on red algae hosts. A presence absence similarity measurement suggested that a single diatom assemblage was hosted in the six red algae taxa. The species composition is highly similar to epiphytic diatom assemblages from NW Mexico, albeit six taxa are new records for Mexican littorals. A photographic catalog of the identified epiphytic diatoms is provided.
Invasive level of the exotic species Neopomacentrus cyanomos (Bleeker, 1856) (Pomacentridae) within the ichthyofauna associated to Orbicella spp. (Scleractinia: Merullinidae) in the Enmedio reef, Lobos-Tuxpan Reef system

Biological monitoring is important for assessing the invasive level of alien species. Therefore, in the present work, the abundance of the exotic fish Neopomacentrus cyanomos was estimated with respect to the native ichthyofauna of the Enmedio reef, Veracruz. Five sampling sites were established on the leeward slope, a reef zone characterized by massive corals; in each place, the richness and abundance of native and exotic fishes were estimated in colonies of Orbicella annularis and Orbicella faveolata. The estimated community attributes were specific wealth, abundance, equitability index, and true diversity. To detect significant differences or similarities in the fish community structure, multivariate techniques were applied: similarity and ordering analysis. A total of 39 species of native fish and two exotic species were recorded: Neopomacentrus cyanomos and Pterois volitans. The most abundant species were Halichoeres burekae and Chromis multilineata, which constituted 89% of the total abundance. In contrast, Neopomacentrus cyanomos presented small populations <15 ind/coral and was common in O. faveolata. In the O. faveolata corals, 39 taxa were found and in O. annularis 35; however, fish abundance was higher in colonies of O. annularis than in O. faveolata. The ichthyofauna was characterized by the dominance of zooplanktophagous fishes; equitable and true diversity were higher in areas with greater coral cover and decreased at places where sand and coral pavements prevail. The ichthyofauna was similar in composition and abundance in O. annularis and O. faveolata as well as between the sampling sites. The small populations of N. cyanomos suggest that it is not a competitive species to the native ichthyofauna; however, it is necessary to continue monitoring in order to assess changes in abundance. In addition, it is imperative to investigate the status of invasion in the other reefs of Veracruz.
