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.

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.

AbstrakKerapu cantik merupakan kerapu hibrid hasil persilangan antara betina kerapu macan dan jantan kerapu batik. Salah satu permasalahan dalam pembenihan kerapu cantik secara umum, yaitu pertumbuhan stadia awal benih kerapu cantik yang lambat. Permasalahan tersebut dapat diatasi dengan menambahkan taurin pada pakan buatan untuk meningkatkan pertumbuhan benih ikan kerapu cantik.Penelitian ini bertujuan untuk mengetahui pengaruh penambahan taurin pada pakan buatan terhadap pertumbuhan dan sintasan benih ikan kerapu cantik. Penelitian ini menggunakan metode RAL dengan tiga perlakuan, yaitu pemberian pakan buatan dengan kadar taurin 0% (P1), 0,5% (P2) dan 1% (P3) yang diberikan pada benih ikan kerapu cantik dan masing-masing perlakuan diulang enam kali. Hasil pemeliharaan selama 45 hari menunjukkan bahwa penambahan taurin sebesar 1% pada pakan buatan memberikan pertumbuhan tertinggi dibandingkan perlakuan lainnya dan berbeda nyata (p<0,05). Penambahan taurin 1% pada pakan buatan tidak memberikan hasil sintasan yang berbeda dengan kontrol (taurin 0%). AbstractCantik grouper is hybrid grouper, it is the results of a crossover between females tiger grouper and males batik grouper. One of the problems in breeding cantik grouper in common is the growth of early stadia juvenile cantik grouper is slow. This problem could be solved by added taurine in the feed to increase the growth of juvenile cantik grouper. The purpose of this research is to find the influence of the addition of taurine in the feed on the growth and survival rate of juvenile cantik grouper. This research used completely randomized design (CRD) method with three treatments, which is giving taurine to feed with 0 % (P1), 0.5 % (P2) and 1 % (P3) concentration given to the juvenile cantik groupers and the treatment has been repeated six times. The results of breeding for 45 days showed that the addition of 1 % taurine in feed give the highest growth than other treatment and differs markedly ( p<0.05 ). The addition of 1% taurine gives no different result with the control variable (0% taurine).
