Optimalisasi budidaya ikan dengan kepadatan tinggi bersamaan dengan peningkatan pemberian pakan akan menyebabkan penumpukan bahan organik. Penumpukan bahan organik ini seperti sisa pakan dan feses akan memperburuk kondisi pemeliharaan, yang pada akhirnya memengaruhi kelangsungan hidup dan pertumbuhan ikan. Kondisi fisiologis ikan akibat lingkungan yang tidak sesuai akan menyebabkan terjadinya perubahan kondisi histologis pada jaringan dan organ yang berperan dalam metabolisme ikan tersebut. Tujuan penelitian ini adalah menganalisis respon perbedaan padat tebar terhadap analisis histologis ginjal ikan nila merah (Oreochromis sp) yang dipelihara menggunakan sistem budikdamber. Penelitian dilakukan selama 28 hari di laboratorium reproduksi dan hidrobiologi Universitas Brawijaya. Pada penelitian ini menggunakan rancangan acak lengkap faktorial dengan perlakuan kepadatan (A (2 ekor/10L), B (4 ekor/10L), C (6 ekor/10L), D (8 ekor/10L) dan sistem (budikdamber dengan kangkung (a) dan tanpa kangkung (b)). Beberapa kerusakan organ ginjal yaitu kongesti, edema dan nekrosis. Perlakuan terbaik adalah Ab (2 ekor/10L tanpa kangkung) yaitu dengan nilai kerusakan paling sedikit.

The potential of freshwater fisheries in local species such as hampal fish (Hampala macrolepidota) presents several research gaps, particularly in specific localities. Research on H. macrolepidota in East Java may serve as a foundation for future management and development of local species, especially given that H. macrolepidota aquaculture is rarely carried out. Morphological studies based on meristics and morphometrics can be used for broodstock selection in H. macrolepidota domestication efforts. In this study, 21 Hampala specimens were assessed based on morphometrics and meristics, and analysed using a significance test, PCA and dendrogram. The analysis results by PCA and dendrogram showed morphometric differences in the Probolinggo and Banyuwangi populations compared with the four Brantas River populations. In contrast, based on meristics, the entire population does not show apparent differences based on the population. The clear differences demonstrated in the Probolinggo and Banyuwangi populations morphometrically indicate local adaptation due to differences in water conditions.

Galangal (Alpinia purpurata) is a herb and medicine plant that is found in Southeast Asia including Thailand, Malaysia, and Indonesia. It is known to have health benefits for its flavonoid, phytosterol, and phenols that are anti-oxidant, anti-cancer, and anti-fungal properties. The phytosterol also can be used for sex hormones production.The exploration of its uses in aquaculture are not yet fully understand. In this LC50-96 experiments were tested for its optimum dosage used in aquaculture by using zebrafish larvae (Danio rerio) as a model. The optimum dosage in the experiments were between 1—31,83 ppm for ethanolic extract of galangal and <0,83 ppm for methanolic extract of galangal. Its uses in aquaculture must be further explored by its effect in fishes behaviors or by the histology of the organs.

Nilem fish (Osteochilus vittatus) is a species of freshwater fish from the Cyprinidae family which has ecological and economic importance in Indonesia, with its natural habitat in rivers, swamps and stagnant waters. Accurate species identification is very important in biological research and fisheries resource management, but morphological identification methods have several limitations. DNA barcoding is a revolutionary molecular technique that uses short DNA sequences to identify and differentiate species with high accuracy. The use of DNA barcoding in identifying freshwater fish in Indonesia has shown significant development, including in a comprehensive study documenting 1,172 native freshwater fish species. The research "Genetic Identification of Nilem Fish using the DNA Barcoding Approach" aims to characterize the genetics of nilem fish, compare the genetic profiles of various populations, and evaluate the effectiveness of DNA barcoding in distinguishing nilem fish from other Osteochilus species, with the hope of contributing to fish conservation and sustainable management efforts nilem in Indonesia. The DNA sequencing results obtained a sequence with a length of 619 base pairs with the composition of Nucleotides A (27.2%), G (17.6%), C (26.4%), T (28.8%). The BLAST results with the NCBI database showed a similarity of 99.84% with the O. vittatus sequence and 99.83% with O. hasseltii. Both species are synonyms with the official name O. vittatus. Phylogenetic analysis is also in line with the BLAST results which show that the sample sequence is in the same clade as the O. vittatus and O. hasseltii sequences. Identification with molecular markers of the COI gene was successfully used in determining the species of the Nilem fish (O. vittatus).

The freshwater fish Beardless Barb Cyclocheilichthys apogon (Valenciennes, 1842) is a native species of Southeast Asia, including the western Indonesia area (Borneo, Sumatra, and Java). Previously, the species was found only in the mainland of Java Island. This paper provides the first record of C. apogon in the Lembung River, one of the major rivers in Madura Island, Indonesia, thereby extending the species distribution up to 150 km northeast from the place of earlier record. The specimens of C. apogon were characterized as follows: dorsal fin rays 12; anal fin rays 8–9; pectoral fin rays 17–18; lateral line scales 34–35. A detailed description of the morphological characters of the specimen is provided in this manuscript.

Glass strain carp (Cyprinus carpio) is highly demanded by farmers due to its delicious, dense meat and fewer spines. To meet the increasing demand for carp, it is necessary to improve the efficiency of aquaculture. The season is known to stimulate one hormone production. The purpose of this study was to determine the effect of season (rainy and dry seasons) on reproductive hormones (follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and estrogen, and interstitial cell-stimulating hormone)) in C. carpio glass strain. Idi research was conducted using the descriptive method by rearing fish in different seasons (rainy season and dry season). The results showed that the reproductive hormone of C. carpio strain glass increased during the rainy season. During the rainy season, changes in the environment and water flow patterns are detected by the fish's sensory system. The results showed that the highest hormones in a row were: ICSH hormone (12.82 pg/mL), FSH hormone (male: 3.73 ng/mL; female: 12.10 ng/mL), LH hormone (12.48 MIU/ml), testosterone hormone (9.27 ng/mL) and estrogen hormone (21.84 ng/mL). Further research is needed to observe the growth and abnormality of fish larvae produced in different seasons.

This study was therefore aimed to determine the effect of different concentration of estrogen hormone, 17β-estradiol (E2) on feminization for the production of all female, growth rate and survival rate of Pacific white shrimp (Litopenaeus vannamei) postlarvae (PL). L. vannamei PL1 were stocked randomly at a density of 10 ind.L-1 into a 10 L of seawater for each experimental flask with three replicates each. PL1 was immersed in seawater containing 0.5, 1.0 and 1.5 mg.L-1 estrogen hormone, E2 for 4 hours. The experiment was continued for 30 days for larval rearing. At the termination of experiment, the specimens in each treatment groups were weighed and measured individually for their wet body weight (BW) and total length (TL) for the mean weight gain, length gain, and the specific growth rate (SGR) estimation. The mean sex ratio values of male to female postlarvae obtained from control till the highest E2 hormone concentration of 0, 0.5, 1.0 and 1.5 mg.L-1 were 1:1, 1:2, 1:9 and 0:1 respectively. The weight gain and length gain were 40605% and 606% for control, 46310% and 647% for 0.5 mg.L-1 concentration, 49310% and 663% for 1.0 mg.L-1 concentration and 45048% and 628% for 1.5 mg.L-1. The mean SGR BW and SGR TL for control till the highest E2 hormone concentration of 0, 0.5, 1.0 and 1.5 mg.L-1 were 20.00 and 6.51, 20.46 and 6.70, 20.67 and 6.77 and 20.37 and 6.62 respectively. The mean survival rate for E2 hormone concentration of 0, 0.5, 1.0 and 1.5 mg.L-1 were 52.67%, 54.33%, 54.67% and 52.33% respectively. The study shows that while the concentration of E2 hormone increased, the female sex ratio of L. vannamei PL also increased but the growth rate and survival rate decreased at concentration of 1.5 mg.L-1. Thus the optimum concentration of this hormone usage was 1.0 mg.L-1 immersed for 4 hours. Keywords: 17β-estradiol, feminization, growth rate, Litopenaeus vannamei, postlarvae, survival rate.
