Nursery of juvenile lobsters in the coastal area was attempted but survival was very low with unknown causes of mortality. The study determined whether communal or individualized houses affect the growth and survival of small and big juvenile lobsters after 60 days nursery culture in the laboratory. Four (4) treatments with four (4) replicates were identified in Completely Randomized Design (CRD) and these were small juvenile lobsters in communal tank (T1), small juvenile lobsters in individualized tank (T2), big juvenile lobsters in communal tank (T3) and big juvenile lobsters in individualized tank (T4). Results showed that communal tank for big juveniles attained significantly (P<0.05) highest weight increment of 5.31±1.66 g compared to individualized house for both sizes of lobsters (2.15±1.45 g and 0.68±0.49 g) and communal tank for small lobsters of 1.26±0.97 g. However, survival rate was very low in all treatments with communal tank obtained the highest survival of 45.75±8.50% with no significant difference among individualized tanks for both sizes of lobsters (29.00±20.93% and 20.75±15.76%) and communal tank for small lobsters (20.92±15.93%). Thus, communal tank is better than individualized tank in the nursery, particularly, for big juvenile lobsters but some aspects of the nursery may be improved to increase higher survival rate.

As one of fish commodity, Catfish (Pangasius pangasius) has a very important economic value for the community. The time needed for catfish cultivation tends to be long and the price of feed is high so that it triggers the less optimal production of catfish. One way to maximize good production and with minimized time is by adding multivitamin probiotics to the feed. This research aims to analyze the optimal dose of probiotics to the growth and survival rate of catfish . Method used is Complete Randomized Design Design (CRDD) using 4 treatments of probiotic doses and 3 replicates. The treatments are A Control (0.00 ml/kg), B (10 ml/kg), C (15 ml/kg), and D (20 ml/kg). Absolute weight, absolute length, and survival of catfish are the main variables observed. The data were analyzed by using the analysis of variance and continued with the LSD test (the Least Significant Difference), Ü = 0.05. The optimal dose of probiotics based on the absolute length and absolute weight of catfish is 10 ml/kg and it produces an absolute weight of 5.27 gram and absolute length of 5.76 cm. The optimal daily specific growth rate is at the probiotics dose of 10 ml/kg which is 2.302.55%/day. The highest survival rate for catfish is 100% at probiotic doses of 0.000 ml/kg, 10 ml/kg and 15 ml/kg. The range of water quality is in the temperature of 27.5 – 28,90C, pH 6.79 - 7.88, DO 6.4 - 7.9 ppm, and ammonia 0 ppm.

Artemia sp. is a common natural feed for shrimps at the post-larvae stage and is characterized by poor lipid content. Therefore, Artemia is commonly enriched with specific nutrition, including biofloc. This contains some useful nutrients in the form of protein and polyhydroxy butyrate (PHB). The aim of this study was to analyze the effect of Artemia enriched with biofloc on the growth performance of black tiger shrimp, P. Monodon, and whiteleg shrimp P. vannamei. This research used acompletely randomized design (CRD), encompassing three treatments of feed and four replications. The tested treatments include: (a) Artemia sp. without enriched (b) Artemia enriched with biofloc, and (c) biofloc without Artemia, and the treatments were fed on black tiger as well as whiteleg shrimp post-larvae for 15 days. The results showed the significant effect of using  Artemia sp. enriched with biofloc on the growth of P. monodon and P. vannamei, but not on the survival rate. However, both parameters were significantly influenced for post-larvae shrimp at a dose of 30 mL biofloc. This served as a nutritional source by providing the best growth of 14.57 mg and 15 mg at a daily growth and survival rate of 0.86 mg day-1: 98% and 1.4 mg day-1: 99% for P. vannamei and P. monodon, respectively.
