Abstract

Jelawat fish cultivation activities are still experiencing problems with low production. In order to increase the production of jelawat fish seeds during the grow-out phase, research needs to be carried out regarding the type of containers for the cultivation. This research aims to determine the best type of container for jelawat fish (Leptobarbus hoevenii) breeding regarding production performance and physiological responses. This study used a completely randomized design with four different treatments in rearing containers and three replications including aquarium (A), fiber tanks (B), concrete tanks (C) and floating net cages (D). The fish seeds used in this study were 2.76 0.15 cm long and weighed 0.17 0.17 g. During breeding process, the fish were given commercial feed with a protein content of 41% and air changes were carried out at 30% of the total air volume every 2 days. The parameters observed in this research include production performance, physiological responses, and air quality. The research results showed that different types of rearing containers had a significant effect on production performance parameters, total cholesterol, and hemoglobin. Total cholesterol and hemoglobin at the start of cultivation were 191 mg/dL and 11.6 g/dL, decreasing at the end of cultivation to 120.28-141.59 mg/dL and 9.03-12.83 g/dL. Air quality was still within the appropriate range for rearing jelawat fish seeds.Keywords:Aquariumsconcrete tanksfloating net cagestarpaulin pondsjelawat fish

Abstract

Seagrass ecosystems have an essential function as a feeding, spawning and nursery areas for various marine biota, etc. There are threats to the sustainability of seagrass ecosystems' biodiversity, one of which is the dumping of garbage into the sea, which causes damage to coastal ecosystems. This study aimed to determine the species and cover of seagrass ecosystems and the type and density of marine debris in seagrass ecosystems in the waters of small islands of Tanjungpinang City. There are three stations: Dompak Island, Penyengat Island, and Los Island. This research was conducted in May-June 2023. Seagrass cover data was collected using the line transect method with a quadrat transect of 50 cm x 50 cm to observe the species and cover. Data collection on marine debris in the seagrass ecosystem was taken on transects with an area of 100 m x 100 m. Marine debris obtained is then grouped by type to calculate density and weight. The types of seagrasses found include Enhalus acoroides, Thalassia hemprichii, Cymodocea serrulata, Cymodocea rotundata, Halodule uninervis, Halodule pinifolia, Halophila ovalis, and Syringodium isoetifolium. The highest total seagrass cover is found on Los Island, with a value of 25.81% classified as poor with a sparse cover category. The types of marine debris found are plastic, glass, rubber, wood, and its derivatives. According to the number of pieces, the highest density of marine debris is plastic waste, resulting in 0.0079 items/m2, and the weight density is 0.0528 grams/m2 found at Los Island.Keywords:biodiversitydebrisplasticseagrasssmall island

Abstract

Chitala lopis, also known as giant featherback, is a fully protected fish species on Indonesian official list due to the susceptibility to exploitation. Several studies showed that the conservation of aquatic resources, such as giant featherback, could be achieved through the implementation of fish farming practices and optimization of feed use. Therefore, this study aimed to determine effect of different feeding rate on growth pattern, performance, and condition factor of the first generation of giant featherback. The first generation of fish was collected from the natural reproduction of broodstock in the earthen ponds. A total of 5 samples were then randomly divided into three treatment groups and reared in the nine net cages installed in the earthen pond. The stocking density in each group was three fish per cage, and the treatments were carried out in triplicates. Feed given comprised fish bycatch as control (T0) (5% of the total weight) and freshwater shrimp, Caridina sp. with two different feeding rates, namely 5% (T1) and 7% (T2) of the total weight. The mean initial weight of all the samples in this study was 41 3.85 g. The results showed that the highest survival and absolute growth rates (29.96.38 g, 78 11%) were obtained in T1, but were not significantly different (p0.05). Furthermore, the highest average relative growth rate was also found in T1 (76.2818.61%) and significantly different compared to other treatments (p0.05). Growth pattern of fish at the beginning of the experiment was negative allometric (0.54), showing a low correlation (0.03), but became positive allometric (4.17) at the end, with moderate correlation (0.66). The results also showed that the highest condition factor was obtained in T2 (0.780.03), and there was a significant effect (p0.05). Based on the results, Caridina sp. had a positive and significant impact on the weight growth of the first generation of giant featherback compared to other studies.Keywords:CultivationFeeding rateGiant featherbackCaridina sp.Rasbora sp.

Abstract

Seagrass restoration practice of transplanting grown seagrass from a donor to the planting site is discovered to disrupt the existing ecosystems. An alternative method includesthe use of seedlings, which requires a protected germination environment to survive. At the initial stage, the seedlings need adequate space for growth and expansion of root systems. However, cultivating seagrass seedlings in aquariums is challenging due to limited space. Therefore, this study aimed to investigate the growth and development of aquarium-cultured seagrass seedlings and evaluate the impact of different spacing on growth. Seedlings were cultivated in the laboratory under 2 treatments, each lasting 3 months. Enhalus acoroides seedlings collected from Dompak Island, Tanjungpinang, were used with varying planting distances for each treatment. The results showed that Treatment A (4 cm spacing) had a lower survival rate (66.73%) compared to TreatmentB (1.5 cm spacing) (97.78%) due to a fungus outbreak.However, Treatment B had slower growth than A, suggesting potential problems with water quality and increased competition for resources in denser plantings. In this study, the significance of planting spacing was outlined and a statistically significant difference was discovered in seagrass growth between various treatments (P0.05). A rapid growth rate of 2.08-3.02 mm/day was observed in leafs, which exceeded the value observed in previous investigations conducted under similar conditions and species. It was important to acknowledge that leaf length was also 17.5-21.6 cm, exceeding the values observed in another experiment using lab-cultured E. acoroides. Root lengths were comparatively shorter (7.6-8.2 cm), which signified the dynamic nature of seagrass development. In conclusion, addressing environmental conditions and optimizing planting spacing, was essential for sustainable growth.Keywords:EnhalusGrowthSeagrassSeedlingsSpacing

Abstract

Silver pompano (Trachinotus blochii) is a mariculture commodity with fast growth characteristics and easy adaptation to the environment. However, the production of its seeds is hindered by the maturation of the parent's gonads out-side the spawning season. Hormonal approaches are needed for the maturation of the parent's gonads. The aim of this study is to investigate the level of steroid hormones, gonadosomatic index, and gonad histology in female silver pompano (Trachinotus blochii) broodstock after dietary supplementation with 17-estradiol. This research is crucial for the advancement of effective and efficient techniques for rearing this fish. The study used a completely randomized design (CRD) consisting of three different 17estradiol concentrations (0 mg/kg (E1), 30 mg/kg (E2), and 60 mg/kg (E3) fed to female silver pompano broodstock for 30 days, beginning at initial feeding, each with eight individual replicates. Absolute body weight growth, steroid hormone levels, gonadal maturation index, gonadal histology, fecundity, and egg diameter of female silver pompano broodstock were all examined in this study. The incorporation of 17-estradiol hormone into the sustenance amplifies the reproductive capabilities of the female silver pompano broodstock. The inclusion of 17-estradiol hormone in the diet renders the most elevated values regarding fecundity and egg diameter in the female silver pompano broodstock. Histological examinations expose that the development of the gonads in the female broodstock treated with 17-estradiol hormone progresses towards maturation. The inclusion of 17- estradiol hormone in the diet at doses of 20 and 60 mg/kg feed yields the highest values in terms of fecundity and egg diameter in female silver pompano broodstock.Keywords:17-estradiolGonadal histologyGonadosomatic indexSteroid hormoneSilver pompano

Abstract

Baby crab consumption has become a growing trend in snack markets across Asia, with rising popularity in at least five countries. Cirebon, situated on the coast of West Java, is a region experiencing particularly high demand for baby crab commodities, notably the locally known "kroyo" crab. However, without adequate information on this species, its future stock sustainability may be compromised. Indonesian regulations governing high-value Crustacea commodities, outlined in Ministry of Marine Affairs and Fisheries Regulation Number 16 of 2022, include lobster (Panulirus spp.), mangrove crab (Scylla spp.), and blue swimming crab (Portunus spp.). This study employs both morphological and molecular analyses, utilizing DNA barcoding techniques. Male (AMJ) and female (AMB) crabs were collected in February 2023 from Gebang Waters, Cirebon, Indonesia. Morphological identification followed guidelines established by the Food and Agriculture Organization (FAO) for crabs, while molecular identification utilized the Cytochrome Oxidase I (COI) gene. Morphological features such as carapace characteristics, front-orbital border, and cheliped spine morphology categorize the specimens under the genus Charybdis. Specifically, the presence of two spines in the cheliped indicates classification as Charybdis anisodon, a conclusion supported by molecular analysis revealing a 98.9298.96% similarity with C. anisodon. Further analysis of the stock of this crab species is necessary to enhance awareness of its exploitation and inform sustainable management practices.Keywords:Baby crabDNA barcodingFisheries managementIdentificationMorphological

Abstract

The Sulawesi Sea is the western entry point of the Indonesian throughflow, which brings water masses from the Pacific Ocean. This study aims to describe the relationship between water mass characteristics and Sound Velocity Profiler (SVP) in the Sulawesi Sea based on Marine Copernicus data from 2022 with a depth of up to 500 meters. Temperature and Salinity data were used to obtain water mass types from the Tpot-S diagram based on Emmery's classification and Sound Velocity Profiler (SVP) based on the Medwin empirical equation. The temperature, salinity, and SVP data were visualized using ODV 5.6.2 software. The data processing results have identified several water mass characteristics that are believed to be influenced by the Eastern North Pacific Central Water (ENPCW) water mass type found at depths ranging from 130 to 318 meters, Western North Pacific Central Water (WNPCW) water mass found at depths ranging from 130 to 500 meters, Eastern South Pacific Central Water (ESPCW) water mass found at depths ranging from 92 to 453 meters, and Western South Pacific Central Water (WSPCW) water mass found at depths ranging from 130 to 500 meters. The ENPCW water mass type on average has a smaller difference in SVP values compared to the WNPCW water mass type. Meanwhile, the ESPCW water mass type on average has a greater difference in SVP values compared to the WSPCW water mass type. The results indicate a positive relationship between temperature and SVP, meaning that the higher the temperature, the higher the SVP. However, there is a negative relationship between salinity and SVP, meaning that the higher the salinity, the lower the SVP.Keywords:Water MassTemperatureSalinitySound VelocitySulawesi Sea
