Instar 1, 3, 5, and 7 phyllosomas of the spiny lobsterJasus verreauxi were reared individually at one of four temperatures (18, 21, 24, and 27C) and fed low, medium, or high rations of 2- to 3-mm Artemia salina. An increase in the temperature reduced the intermoult period for all instars tested, but only the instar 5 phyllosomas showed any significant differences in postmoult size with temperature; those at 18C were smaller. Phyllosomas reared at 18C ate fewer Artemia each day than did those at the higher temperatures, but instars 3 and 5 at 18C consumed more in total over the intermoult period. Survival for all instars tested was lowest at 18C. Increasing the food rations affected the growth and survival of instar 5 and 7 phyllosomas; those fed at the lower rations took longer to moult and had a smaller growth increment. For all instars tested, the feeding rate and total consumption increased with food ration.

Stage I J. edwardsii larvae that had hatched from embryos held at one of three temperatures were reared at 12˚C to 24˚C and fed 2–3 mm brine shrimps. Larvae reared at 24˚, 21˚, 18˚, 15˚ and 12˚C moulted to Stage II after 7, 8, 11, 17 and 33 days respectively. Larvae from 18˚ and 15˚C embryos reared at 24˚C had 40% and 100% survival respectively. Larvae reared at 12˚C had 10–15% survival. Stages II, IV, VI and VIII larvae were reared at three temperatures and fed 4, 8, 12, 16, 24 or 36 brine shrimp per day. At optimum feeding levels and at 24˚, 21˚ and 18˚C, Stage II larvae moulted after 6, 8 and 11 days respectively, Stage IV after 9, 10 and 12 days, Stage VI after 12, 14 and 17 days and Stage VIII after 18, 21 and 25 days. Survival was generally >70% but at 24˚C when fed >16 brine shrimp survival was <40%. For all stages, consumption rates increased but total consumption decreased with increasing temperature. For Stages II, IV, VI and VIII the intermoult period increased as the brine shrimp ration reduced. Larvae were successfully reared up to Stage VI ~25% faster at 21˚ than at 18˚C.

Completely Randomized Design

The aim of this study was to determine the growth and survival rate of Ctenopoma fish seeds. This study used a completely randomized design with 3 treatments and 3 replications. The treatment in this study was a different feeding rate using natural feed of Tubifex sp  namely A (8%), B (10%), and C (12%) ). The test fish used was Ctenopoma fish seeds with an initial length of 2.40 ± 0.10 cm and an initial weight of 0.32 ± 0.05 g. Fish seeds are cultivated  for 28 days with feeding frequency twice a day. The results of research showed that the use of different feeding rate had an significantly different (P<0.05) on the specific growth  rate and absolute length growth with the best results in the treatment C. The survival rate was not significantly different between treatments (P>0.05). Key Words: Ctenopoma, feeding rate, growth, survival rate

Laju pertumbuhan dan tingkat reproduksi yang tinggi merupakan karakteristik unggul yang dimiliki ikan nila sebagai komoditi budidaya. Tingkat reproduksi yang tinggi menyebabkan terjadinya pematangan gonad sebelum mencapai ukuran produksi dimana hal tersebut dapat merugikan pembudidaya, karena saat ikan mengalami matang gonad energi hasil asimilasi pakan sebagain besar akan dialokasikan untuk perkembangan gonad dan menghambat pertumbuhan somatik. Pemanfaatan senyawa aktif dari bahan alami biji pepaya dapat menjadi solusi untuk meningkatkan pertumbuhan ikan yang dibudidayakan sekaligus menjaga keamanan pangan dan konsumen. Penelitian ini bertujuan untuk mengetahui pemanfaatan tepung biji pepaya terhadap respons pertumbuhan dan tingkat kelangsungan hidup ikan nila. Ikan nila diberi perlakuan dengan lima dosis tepung biji pepaya berbeda (0, 1, 3, 5 dan 7 g/kg pakan) secara oral berdasarkan feeding rate 5% dengan tiga ulangan selama 30 hari pemeliharaan. Hasil penelitian menunjukkan dosis 5 g/kg meningkatkan pertumbuhan bobot tubuh tertinggi sebesar 547 g dibandingkan kontrol sebesar 406 g. Sejalan dengan pertumbuhan bobot tubuh, dosis 5 g/kg menghasilkan tingkat kelangsungan hidup ikan nila sebesar 100% dibandingkan kontrol sebesar 66%. Dari hasil yang diperoleh dapat disimpulkan bahwa tepung biji pepaya dengan dosis 5 g/kg pakan dapat meningkatkan pertumbuhan dan tingkat kelangsungan hidup ikan nila selama 30 hariHigh growth rate and high reproductive cycle are some economical triats on nile tilapia. This is a setback for nile tilapia culture because when the fish reach gonad maturity before reach market size, all the energy demand will flow to reproduction and can cause stunt growth. The utilization of natural compound from papaya seeds can be a solution to enhance growth of farmed nile tilapia and for consumer and food safety. This research aim to know how papaya seed powder can enhance growth and survival rate of nile tilapia. This research conducted into five groups of 5 papaya seeds powder dosage (0, 1, 3, 5 and 7 g/kg) that feed orally to the treatment fishes. Result showed the fishes feed with 5 g/kg papaya seed experienced highest growth performance 547 g compare to control which is 406 g. Same as growth performance, survival rate shown that group feed with 5 g/kg papaya seed had 100% survival rate compare with control which is 66% during treatment periods. Base on this result, we can make conclusion that fish feed with 5 g/kg of papaya seed have a better growth performance and survival rate compare with control group for 30 days treatment periods
