Two experiments were carried out to evaluate the effects of addition of net piece substrates in cages for nursery rearing of freshwater prawn, Macrobrachium rosenbergii post-larvae. In the first experiment, net piece substrates were added with an arrangement to increase the surface area of nursery cages to 50% and 75% and compared with cages without any substrate (control). In the second experiment, maintaining surface area increment at 75% in all cages, the net piece substrates were arranged in three different orientations of horizontal, vertical, and 45o angle sloping. Experiments were conducted in a pond of Faculty of Fisheries, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh for a period of 45 days in June –August of 2015 and 2016. A completely randomized design was followed to assign the treatments with three replications. The 75% area increment group showed significantly higher (P < 0.05) growth (1.02 ± 0.09 g) and survival rate (79.43 ± 1.63%), compared to 50% area increment (0.96 ± 0.05 g and 75.03 ± 2.45%) and control group (0.79 ± 0.06 g and 66.66 ± 3.57%). The vertically oriented substrate group showed significantly lower growth 0.95 ± 0.04 g) and survival (76.33 ± 1.15%), compared to the horizontal (1.06 ± 0.05 g and 77.12 ± 1.20%) and sloping (1.16 ± 0.10 g and 79.33 ± 0.57 %) substrate group. However, there were no differences between horizontal and sloping substrate groups regarding final length, final weight, specific growth rate (SGR), and survival rate except food conversion ratio (FCR). The overall results suggested that modification of net cage nursery structure of M. rosenbergii might have significant effects on growth and survival of post-larvae by the manipulation of their behaviour in culture system.

Preliminary Study

This experiment was conducted to investigate the influence of vitamin C on growth and survival rate of freshwater prawn larvae. The treatment dosages of vitamin C were 0.0, and 0.75 mg/L. Each treatment was in triplicates and arranged in a complete randomized design. Vitamin C was given to the larval rearing media every three days. Larvae were cultured in six conical fibreglass tanks of 50 L volume installed in a fibreglass tank (2 m x 0.8 m x 0.8 m) filled with water for temperature stabilizer. Each conical tank was stocked with 6,500 larvae (nauplii). Artemia nauplii were given on D3 and egg custard as artificial feed on D9. Larval rearing was done for 25 days in constant temperature (29oC–31oC) using automatic heater. Statistical analysis showed that metamorphosis speed of larvae was significantly affected by adding of vitamin C (P<0.05), but survival rate was similar (P>0.05). Addition of vitamin C also resulted in a better growth of freshwater prawn larvae.

This study aimed to evaluate the growth, survival rate, and resistance to acute hepatopancreatic necrosis disease (AHPND) of white leg shrimp (Penaeus vannamei) by using Lactobacillus plantarum, Lactobacillus fermentum, and Pediococcus pentosaceus mixed with feed, and at the same time supplying CNP in a ratio of 15:1:0.1 to the water. As a result, the treatments that shrimp were fed with feed containing lactic acid bacteria (LAB), especially L. plantarum, have increased shrimp growth, total hemocyte cells, granulocyte cells, and hyaline cells significantly (p < 0.05) in comparison to the control group. The supply of CNP to the water has promoted the intensity of V. parahaemolyticus effects on shrimp health and significantly decreased total hemocyte cells, granulocyte cells, and hyaline cells by 30–50% in the period after three days of the challenge, except in L. plantarum treatment, which had only a 20% decrease compared to other treatments. In CNP supplying treatments, the AHPND infected rate and mortality of shrimp were higher than those in other treatments. In summary, the supply of CNP had significantly reduced the shrimp’s immune response and promoted the susceptibility of shrimp to AHPND in both cases of use with and without LAB-containing diets.

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

ABSTRACT The development of lobster farming in floating net cage in Ekas Bay caused an environmental degradation such as decrease water quality due to some aquaculture wastes. The purposes of this study were to determine the status of water quality and their effect on growth and survival rate of lobster reared in floating net cages (FNC) in the Ekas Bay, West Nusa Tenggara Province. Water sample collection and handling referred to the APHA (1992). Analyses of water quality data were conducted using Principal Component Analysis. Determination of the water quality status of Ekas Bay was performed with STORET system. Multivariate analyses were used to determine the relationship between water quality, growth, and survival rate of lobster reared in FNC. Results showed that Ekas Bay water quality status was categorized in class C (medium contaminated), which exceeded some quality standard parameters such as ammonia (0.3 mg/l), nitrate (0.008 mg/l), and phosphate (0.015 mg/l). During lobster farming activities feeding with trash fish for 270 days, we obtained daily growth rate of  0.74% (lower than normal growth rate of 0.86%), survival rate of 66% (lower than normal survival rate of 86.7%), and feed conversion ratio of 11.15. Ammonia was found as a dominant factor reducing growth  and survival rate of lobster reared in FNC. Keywords: water quality, lobsters, growth, survival, Ekas Bay
