Intensification of white shrimp (L. vannamei) cultivation causes accumulation of waste aquaculture in the water and environmental stress which causes pathogenic organisms to develop and attack aquaculture organisms, so that mass deaths occur. Various efforts have been made to overcome this through feed production by adding ingredient that can enhance the body's immune system, but also function as growth promoters. The material that has both functions is seaweed Sargassum sp. The aims of this study was to determine the addition effect of sargassum extract from enzymatic extraction on feed to the specific growth rate/SGR and feed convertion ratio/FCR of white shrimp (L. vannamei). These study was conducted by experimental method used a completely randomized design (CRD) with 3 treatments and 2 repetitions. The treatment was namely A (feed with the addition of sargassum extract 0 g/kg feed), B (feed with the addition of enzymatically protease sargassum extract 2 g/kg feed) and C (feed with the addition of enzymatically carbohydrase sargassum extract 2 g/kg feed). The results showed that the feed with the addition of sargassum extract from enzymatic extraction had a significant effect (P<0,05) on specific growth rate (SGR) and feed conversion ratio (FCR). Water quality of media is in the proper range for shrimp farming.

Ikan Tor merupakan genus yang potensi dibudidayakan karena memiliki nilai ekonomis tinggi. Masalah yang ada adalah lambatnya pertumbuhan dan rendahnya tingkat sintasan benih ikan tersebut dalam jumlah yang memadai untuk pembudidaya. Hibridisasi atau persilangan merupakan suatu upaya untuk mendapatkan kombinasi antara populasi yang berbeda untuk menghasilkan keturunan yang memiliki sifat unggul. Hibridisasi tiga spesies ikan Tor secara resiprokal antara Tor soro (Ts), Tor douronensis (Td), dan Tor tambroides (Tt) dilakukan guna untuk mengetahui keberhasilan hibridisasi beda spesies tetapi masih dalam genus. Metode yang digunakan pada penelitian ini adalah eksperimen dengan enam perlakuan dan tiga kali ulangan hasil hibrida. Hasil yang diperoleh menunjukkan nilai derajat pembuahan tertinggi dihasilkan dari hibridisasi Td >< Ts (93,66 ± 1,15%), daya tetas tertinggi dihasilkan dari persilangan Td >< Ts (88,00 ± 1,00%), laju pertumbuhan spesifik bobot tertinggi dihasilkan dari hibridisasi Ts >< Td dan Ts >< Tt (5,62 ± 0,17%; 5,44 ± 0,06%), laju pertumbuhan spesifik panjang tertinggi dihasilkan dari hibridisasi Ts >< Td (1,79 ± 0,11%) dan sintasan tertinggi dihasilkan dari hibridisasi Tt >< Ts (86,00 ± 3,60%). Nilai heterosisyang meliputi derajat pembuahan, daya tetas telur, pertumbuhan benih, dan sintasan ikan sampai umur 41 hari menunjukkan nilai negatif, kecuali laju pertumbuhan spesifik bobot. Hibridisasi berdampak pada meningkatnya jumlah larva abnormal yang dihasilkan dibanding tetuanya (pure breed).Tor fish has the potential to be commercially developed as a farmed fish due to its high economic value and market demand. However, slow growth and low survival rate of the fish larvae and insufficient seed availability for aquaculture farmers are the main bottlenecks to develop a profitable aquaculture for tor fish. Hybridization or crossbreed is an attempt to get a combination between different populations to produce offspring inheriting superior characters. A reciprocal hybridization between Tor soro (Ts), Tor douronensis (Td), and Tor tambroides (Tt) was carried out to assess the success rate of hybridization between the three species. The study used an experimental design with six treatments and three replications to measure and compare hybridization and survival parameters between the species. The highest fertilization rate attained by hybridization Td >< Ts (93.66 ± 1.15%, the highest hatching rate was achieved by Td >< Ts (88.00 ± 1.00%), the highest weight specific growth rate was gained by hybridization Ts >< Td and Ts >< Tt (5.62 ± 0.17%; 5.44 ± 0.06%), the highest lenght specific growth rate was achieved by hybridization Ts >< Td (1.79 ± 0.11%) and highest survival rate was resulted from hybridization between Tor tambroides >< Tor tambroides (90.33 ± 1.52%). The observed heterosis (degree of fertilization rate, hatching rate, growth rate, and survival rate until the age of 41 days) showed that all parameter characters were negative, except for the weight-specific growth rate characters. This study concludes that hybridization have an impact on increasing the number of abnormal larvae produced compared to their parents (pure-breed).

Eel (Anguilla bicolor) is a export commodity fish in fisheries sector and has has high economic value but has slow growth. One method to accelerate eel growth is through feeding with the enrichment of fish oil. The aim of this research is to know the increase of growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil. The study used 3 treatments and 3 replications ie A (0% fish oil / control), B (1.5% fish oil), and C (3% fish oil). Parameters observed included specific growth rate, feed consumption total, feed efiesiensi, fat retention, survival rate. The supporting parameters are water quality. The result of research obtained were tabulated and analyzed by excel 2013 program and SPSS v. 20.0. with 95% confidence interva and continued by Duncan test. The results showed that there was a significant effect (P <0.05) on the growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil. Treatment C (3% fish oil) is the optimum dose because it has the best growth performance and best feed efficiency that is specific growth rate (4,61% ± 0,0075), total feed consumption (246,3 g ± 50,1), feed efiesiensi (42,5% ± 3,74), fat retention (2,97% ± 0,148) and survival rate (86,7% ± 11,5).

Snakehead fish (Channa striata) is a member of the Channidae family, which can live in freshwater areas or rivers, brackish water, and swamps. Snakehead fish belong to the group of savage and aggressive carnivorous fish. Snakehead fish reproduce through spawning naturally in the rainy season. Natural physiological and environmental factors can be used as a signal to stimulate spawning in this type of fish. This fieldwork practice was carried out at the Center for Aquaculture Technology Development (BPTPB), this work practice used observation, interview, and documentation methods, parameters observed included fecundity, egg fertilization, hatching rate, specific growth rate, and survival rate. The results of the observation showed that it produced 10,000 eggs, a fertilization rate of 92%, a hatching rate of 94% growth rate, a specific growth rate of 15% and a survival rate of 94%.
