Abstract

B. pectinirostris constructs different shapes of burrows on the surface of the sediment because of different functions. This study was to determine the effect of burrows on total organic matter (TOM) on the sediment surface in the mangrove ecosystem in Pandansari Brebes, Central Java. Sampling was divided into mangrove areas and muddy beach areas. The shape of the burrows was visually observed in a year. TOM was taken from inside and outside the burrow in June and September using a syringe and analyzed by the LOI method. B. pectinirostris had circular burrow openings at the same height as the ground surface. At the mouth of the burrow, there were traces of fish coming in and out. The diameter of the burrows was around 3-4cm in the muddy beach area and 2-9cm in the mangrove area. TOM in the mangrove area inside the burrow was 9,034±0,851% and outside was 8,470%±0,967% and in the muddy beach area inside the burrow was 8,754%±0,476% and outside was 8,558%±0,924%. There was no difference in TOM inside and outside the burrow in the two areas (P>0.05). It is likely caused by the locomotion of fish and tidal stirring, so the burrows do not function as a TOM trap.

Abstract
In the policy context, managing grouper and snapper fisheries resources for sustainability is a big challenge due to the complexity of small-scale fisheries in Saleh Bay. This study implemented two analytical methods: length-based analysis and ecosystem approach to fisheries assessment to evaluate the performance of the implementation of the grouper and snapper fisheries management in Saleh Bay. The results showed after policy implementation, the mean length of species has been slightly larger and three species already reached the spawning potential ratio (SPR) target reference point. However, two of the 11 species regulated had SPR values below the limit reference point, which indicated that these species are currently fished at unsustainable levels. Overall, the assessment of fishery risk index indicated the risk status of this fisheries in the category of moderate risk, 1.185, in which two dimensions need to be improved: socio-economy and habitat. Therefore, this study highlighted leverage points to achieve ‘good’ performance level, such as socialization program intensively, enforcing regulation to provincial regulation, strengthening the surveillance and law enforcement of destructive fishing practices, empowerment of local institutions by co-management, and rehabilitation of coral reef ecosystems.

Abstract
Saleh Bay is one of the locations where whale sharks (Rhincodon typus) occurrence observed in Indonesia and can be found all year round. Whale sharks broadly distributed throughout tropical and sub-tropical waters of the world’s oceans. Immature male is less than 7 m long, while female is less than 10 m, mostly tend to coastal habitat related. Result of research by Conservation International presented at International Whale Shark Conference in Australia in 2019, Whale Sharks in Saleh Bay had home movement patterns. This study aims to prove that Saleh Bay is the residential area of the whale shark. This study was conducted from November 2019 to January 2020. The Photo-ID data obtained were compared with CI’s Saleh Bay Whale Shark ID Catalog data which last update on April 2020. Surface temperature was measured directly in the range of 29-320C, data for chlorophyll-a were taken from marine.copernicus.eu and bathymetry from cmap.ihms.us then interpolated using QGIS 3.10 software. From this study period, 24 Photo-IDs were obtained from 39 whale sharks, which identified as 23 males, 1 female, and 6 were new individuals from June 2019 to April 2020. The size of the whale sharks recorded in this study ranged from 2,5 to 7 m with 4,86 m in average, and considered as juveniles.

Abstract
Three groups of marine biotas in the coral reef ecosystem were analyzed to determine the overall condition coral reef ecosystem in Natuna Island (coral, reef fish, and megabenthos). Nineteen sampling sites are distributed completely in Natuna Island, including Natuna Besar Island, Tiga Island, and Sedanau Island. The coral reef monitoring refers to the Underwater Photo Transect (UPT), and data processing used the Coral Point Count for excel (CPCe). The reef fish observation using the Underwater Visual Census (UVC) and megabenthos observations using the Benthos Belt Transect (BBT). The percentage of the benthic cover was analyzed for several benthic categories. The analysis for reef fish consisted of diversity and abundance for the three fish groups, including the corallivore, herbivore, and carnivore. The megabenthos community’s analysis consisted of diversity and density from eight groups, including giant clams, lobster, Drupella sp., Linckia laevigata, sea urchin, sea cucumber, trochus, and Acanthaster planci. The Coral Reef Health Index (CRHI) analysis was used to determines the coral reef condition in Natuna. Nine sites were categorized as the fair condition of live coral cover with 26.53–36.87%. The largest composition of coral reef fish groups from herbivorous groups and the highest density megabenthos was sea urchins.

Abstract
A body weight based selection protocol is the most common practice in the genetic improvement programs for aquaculture species. It might be one of the criteria to be considered in the aquatic resources management scheme. This experiment aimed to evaluate the genetic enhancement of selected first-generation (G1) of red tilapia. Fish were bred under fullsib mating design at hapa of 2×2 m2. The communal growing out of fingerlings was carried out in an earthen pond for 120 days. The stocking density of fingerlings was 7 fish per m2. Fish were fed with commercial floating fish feed at a rate of 5-10% of biomass twice a day. The results showed that the population of males and females of red tilapia in the first generation (G1) grew faster than the previous generation (G0). The selection response values were 19.52 % and 12.05 % for male and female populations, respectively. The heritability values in male and female red tilapia populations were in the medium category with a value of 0.33 and 0.25, respectively. The results showed that the breeding program increased the genetic quality of fish in terms of body weight based growth in the first generation of red tilapia.

Abstract
Free amino acid taurine is found in sea slugs. It has been used as a preventive agent for cardiovascular disease and inflammatory disorders. Inflammation takes place in the presence of lipopolysaccharide (LPS), as a specific inducer, which provokes activation of molecular signals controlling the development of pro-inflammatory and anti-inflammatory cytokines. This current work investigated the effects of taurine extract from shell-less sea slugs on the inhibition of IFN-γ as pro-inflammatory cytokine and IL-10 as anti-inflammatory cytokine in LPS-induced mice lymphocytes. The crude taurine was extracted using water solvent maceration of the sea slug’s mucus. Culture of mice splenocytes in RPMI-1640 medium underwent for 5 days and they were then analysed by flow cytometry. As the result, crude taurine extracts substantially suppressed NF-kB expression in T cells, found in all concentrations. The best inhibitory effect was attributed to 500 μg/mL, which was significantly different over control groups (p<0.05). Additionally, the extract inhibited expression of CD4+ IFN-γ
+ pro-inflammatory cytokines at 500 μg/mL• being stronger than inhibition by control (p<0.05), while it improved expression of CD4+IL-10+ anti-inflammatory cytokines at 500 μg/mL compared with control (p<0.05). Our experimental results indicated potential use of taurine crude extract isolated from sea slug Paraonchidium as anti-inflammatory agent from marine source.

AbstractIn aquaculture, feed cost contributes the highest share in the total production cost. The increase in fishmeal price and the high cost of commercial fish feeds have prompted the search for alternatives. Thus, considerable research has been carried out to develop a farm-made feed that requires simpler methods and cheaper production costs. This study aimed at developing farm-made fish feed using simple equipment, locally available materials, and inexpensive fungal-based bio-floating technique. A combination of using black soldier fly (Hermetia illucens) larvae meal as a fishmeal replacement andRhizopussp. fermentation to provide floatability was used. An experiment using three differentRhizopussp. inoculum doses (1, 2, and 3% w/w) and 3 different fermentation duration (30, 40, and 50 h) were designed, with unfermented feed as control. Results showed that fermented floating feeds gained better nutritional value and physical characteristics (p<0.05). The optimized treatment resulted in a fermented feed with the protein content of 29.72%; fibre 12.13%; fat 26.57%; and ash 7.83%. Relative to the unfermented control, all of the fermentation treatments produced feeds with high average values of floating ability (83.33%) and water stability (92.38).

Abstract
The Ocean Decade 2021-2030 was declared at the end of 2017. The Decade Declaration is aimed at accelerating the resolution of various social-ecological issues facing the oceans collectively and holistically by involving multi-stakeholders: natural and social scientists, governments, NGOs, private parties, and local communities. Indonesia as a large maritime country must play an important role in this Decade, both as a provider and as a beneficiary. The aims of this paper are to (1) convey important things about the Ocean Decade and (2) provide recommendations for carrying out three types of research to prepare for the Ocean Decade. This exploratory study is conducted qualitatively, using a literature review of UNESCO official documents as well as various other literature, such as scientific journal articles. An interview with a key informant was conducted for initial stakeholder analysis. The results of the analysis and the recommendations are expected to be used to help various stakeholders in Indonesia prepare to take part in the implementation of ‘The Ocean Decade’.

Published: May 2021

Abstract
Seaweed Gracilaria sp. and milkfish are euryhaline fishery commodities. Both of these commodities can be cultivated by polyculture in ponds. Polyculture is a mixed cultivation technology between two or more commodities that can increase aquaculture production and provide value added cultivators as it can harvest several products in one season. Polyculture seaweed Gracilaria sp. and milkfish are done at Marana Experimental Pond Installation, Research Institute for Coastal Aquaculture, Maros South Sulawesi with extensive technology system, using 1 plot of pond size 10,000 m2. Preparation of the pond begins with the repair of dikes, patching leaks and repair of sluices. Next is draining ponds, eradicating pests with 20 ppm saponin, pond flushing, subsequent fertilizing and preparation of water for dispersal. Initial fertilization is done by using Urea and TSP fertilizers with doses of 100 and 50 kg/ha. Seaweed seed stocking in ponds as much as 2,000 kg/ha was done in March using a broadcast method, i.e., seed stocked in all parts of ponds. The milkfish seeds are also stocked with a dense stocking of 1,000 tails/ha. The first harvest of seaweed can be done after the maintenance period of 3.5 months. The next harvest can be done every 30-45 days. Total production of dried seaweed reached 8,284 kg/ha (5 times harvest/year) and milkfish harvest reached 375 kg/ha.

Abstract
One form of fishery product diversification is in the form of smoked fish product, favored by the community because it has a delicious aroma and distinctive taste. Most fish smoked processes in Indonesia are traditionally carried out on a small scale (household) using simple tools that do not pay attention to sanitation and hygienic aspects. The huge potential for smoked fish is often seen as a source of pollutants that the local community complains about because its activities are considered to have an impact on health and environmental changes. This research objective aims to identify the physicochemical parameter of waste contained in smoked fish processing activities at Alo River, Penatarsewu Village, Sidoardjo Regency, East Java. Research conducts from September-November 2020, with direct sampling method of wastewater, a disposal site for fish smoking waste by determining the wastewater sample stations along the river, guided by the direction of the flow. Physicochemical properties including pH, TSS, TDS, BOD, and COD were analyzed by Standard Method for the Examination of Water and Wastewater. The result showed pH effluent was within the intolerance limit of 6-9. The highest TDS and TSS are showing by sample 9 were higher than the threshold limit value. The value TDS in sampling point 6 to 9 shows the TDS value was higher than the threshold limit value. The concentration of BOD and COD in the effluent sampling points 8 and 9 were higher with permission limit value Government Regulation, The Republic of Indonesia (PPRI) No. 82, 2001. It is caused by the presence of heavy equipment used as dredging activity along the river carried out by the local government. This indicates that pollution from fish smoking activities in Penatarsewu Village can be said to be insignificant when compared to activities outside fisheries.

Abstract
The background colour of a tank can affect the intensity of light that is absorbed or reflected. The objective of this research is to evaluate the colour preference of the scalloped spiny lobsters. Colour preference observations were carried out every half hour for 24 h. The result showed the spiny lobster had a consistent preference for black background (> 35%) and aversion to yellow, white, blue, and green background (P <.05) in the day. In the dusk, the spiny lobster had a consistent preference for red background(> 25%) and aversion to black, yellow, white, blue, and green background (P > .05). In the night, the spiny lobster had a consistent preference to red background (> 30%) and aversion to white and yellow background (P <.05). The number of lobsters moving towards the red tank continues to increase in the night rather than the dusk. Nocturnal activity is still going on the dawn.

Published: May 2021

AbstractInland fisheries are a significant sector especially for those living in villages as a source of both nutritious yet affordable food and the community’s income. The increasing pressure on inland fisheries causes a reduction in the amount and size of fish caught as well as the rarity of some species of fish. One measure taken to intensify inland fisheries is by implementing inland aquaculture. Unlike any other controlled condition aquaculture, inland aquaculture is done with adjustment to the water condition. This study aims to describe characteristics of several inland waters of Ogan Komering Ilir regency, South Sumatera Province, Indonesia in particular as well as to provide a guideline for inland aquaculture based on the characteristics of the waters. The description is done by reviewing a number of academic journals and publications which are verified by academics and expert judgment. The main points in describing inland fisheries are water typology, fish resource, water quality, and social community characteristics. After analyzing the inputs from inland fishery characteristics based on the 4 main points previously mentioned, a guideline is created for conducting fish farming in terms of farming methods, seed selection, seed stocking criteria, and institutional arrangement in fish ownership issue.

Abstract
One of the economically valuable consumption fish in Ranau Lake is the hampala barb (Hampala macrolepidota). Hampala barb is the top predator in Ranau Lake. The fish population is still quite a lot, but it is starting to decline. This study aimed to determine the reproductive biology of hampala barb in Ranau Lake. Ranau Lake is located in South Sumatra Province and Lampung Province, Indonesia. The research was conducted by the inventory survey method and laboratory analysis. Fish samples were obtained from fisher’s catch, where the fish were caught using gill nets with varying mesh sizes and harpoon. The fish were measured for length body and total weight. Then surgery was performed to determine their reproductive biological characteristics (sex, size of first gonad maturity, gonad maturity stage, Gonad Somatic Index, fecundity, and egg diameter). The results showed that the hampala barb in Ranau Lake laid the eggs throughout the year with a sex ratio of 1: 1, the size of the first stage of gonad maturity of male and female were 15.38 cm and 19.21 cm, fecundity between 17,406-63,793 eggs, and egg diameter between 0.8-1.9 mm. This reproductive biology information can be used for the management of hampala barb in Ranau Lake.

Abstract
Bima Bay, as an ecosystem, is very interesting to understand in its relation between the changes in land use/land cover with ecosystem services. The purpose of this study was to determine the condition of ecosystem services in Bima Bay. The data analysis methods used were: field surveys, independent interviews with stakeholders regarding the direction of development in the Bima Bay area, and spatial information sourced from relevant documents. The results showed that the highest ecological integrity index value was found in West Rasanae Sub-district at 0.5592 and the lowest integrity value was in Soromandi Sub-district at 0.3051. The highest value of the inventory service index was found in West Rasanae Sub-district at 0.1526 and the lowest was Soromandi Sub-district at 0.0981. The highest index value for regulating services was found in West Rasanae Sub-district at 0.3333 and the lowest was Soromandi Sub-district at 0.2119. The highest index value for culture services was 0.5143 and the lowest was Soromandi Sub-district at 0.2143. Meanwhile, the value of the index value of the Bima Bay ecosystem services budgets was -1.8138, this showed that human demand for ecosystem goods and services was greater than the ability to provide them (supply<demand).

Published: May 2021

Abstract
Previous data of the whole mitochondrial genome of soft-shelled turtle that it’s available in a public repository: Dogania subplana, Pelochelys cantorii, Chitra indica, Trionyx triunguis, Apalone spinifera, Rafetus swinhoei, and Pelodiscus sinensis. The first two species have natural distribution in Indonesia. Amyda cartilaginea is a species of soft-shelled turtle that is abundant in Indonesia. However, the whole mitochondrial genome data of A. cartilaginea is not available. This study aims to characterize the partial mitochondrial genome and analyze the phylogenetic position of A. cartilaginea. We reported almost complete mitochondrial genome of A. cartilaginea that caught from Batanghari river in Dharmasraya District, West Sumatera. The amplification of mitochondrial DNA fragments was performed using several primers designed following mitochondrial gene organization and sequence of D. subplana (Accession No AF366350). We sequenced half of the whole mitochondrial genome (7757 bp, 48%). The gene organization of the mitochondrial genome of A. cartilaginea was identic with D. subplana and P. cantorii. The phylogenetic tree analysis based on 16SrRNA revealed that the position of A. cartilaginea clustered with another soft-shelled turtle. Further study is needed to make a complete sequence of the mitochondrial genome of A. cartilaginea, with special focus on the control region to be applied to sustainable wild population management.

Abstract

Selaroides leptolepis is one of the most common pelagic fish, which has high market demand in Gorontalo. This study aimed to provide growth patterns and sex ratio of S. leptolepis male and female inhabiting Tomini Bay, Indonesia. Sampling was conducted monthly for six months, from April 2020 to September 2020. A fish sample of 1168 was taken randomly from Tomini Bay fishers who landed their catch at Kampung Tenda Fish Landing Site, Gorontalo City. The length and weight of fish were measured using a ruler (nearest 1 mm) and an analytical scale (nearest 0.01 g) separately. The results showed that almost all captured exhibited positive allometric growth (b > 3) and tended to be plump, except for the female in May 2020. The sex ratio between males and females during the sampling periods was 1: 1.17, which means the population proportion is not balanced. Such data are essential for establishing fisheries management in Tomini Bay.
