Reducing feed cost in the vaname (Litopenaeus vannamei) cultivation can be achieved by increasing quality of commercial feed. To increase the feed quality is by adding lysine amino acid, because lysine is one of the amino acids  that can boost fish growth, in turn it can shorten the cultivation cycle. The objectives of the study were to analyze effects and optimum dosages of lysine addition in the feed on feed efficiency utilization, growth and survival rate of vaname shrimp (L. vannamei). The study used shrimp juveniles with the average size of 3±0,09 g/shrimp.  Test feed in the study was a commercial feed in the form of pellets that was enriched with lysine (L-lysine HCl).  The amount of lysine was appropriated to the treatment dosages, namelys 0%/kg feed (A); 0,75 %/kg feed (B); 1,5%/kg feed (C); 2,25%/kg feed (D) and 3%/kg feed (E). Feeding the shrimp was based on fixed feeding rate as much as 10% of biomass weight per day and given 4 (four) times a day.  The results whow that the addition of lysine in the feed significantly (P<0,01) affected on the SGR, EPP, FCR, and PER; otherwise, it did not significantly affect on the survival rate of vaname shrimp.  Meanwhile, the optimum dosages of lysine amino acids added into the feed were 2,33%, 2,39%, 2,37%, and 2,09% for SGR, EPP, FCR, and PER respectively.  Those dosages resulted in the maxium values of  4,72%/day,  81,35%,  1,23, and 2,57 for SGR, EPP, FCR, and PER respectively.   Penurunan biaya operasional pakan dalam siklus kegiatan budidaya udang vaname (Litopenaeus vannamei) dapat dilakukan dengan meningkatkan kualitas pakan komersial.  Penambahan asam amino lisin pada pakan komersial dilakukan untuk meningkatkan kualitas pakan, dikarena lisin merupakan salah satu asam amino dapat mempercepat pertumbuhan sehingga memperpendek masa produksi kultivan yang dibudidayakan. Tujuan penelitian ini untuk mengkaji pengaruh dan dosis optimum penambahan lisin pada pakan komersil terhadap efisiensi pemanfaatan pakan, pertumbuhan, dan kelulushidupan udang vaname (L. vannamei). Penelitian ini menggunakan juvenile udang vaname berukuran 3±0,09 g/ekor. Pakan uji dalam penelitian ini adalah pakan komersil berbentuk pellet yang ditambahkan lisin (L-lysine HCl) sesuai dosis tiap perlakuan yaitu 0%/kg pakan (A); 0,75 %/kg pakan (B); 1,5%/kg pakan (C); 2,25%/kg pakan (D) dan 3%/kg pakan (E). Pakan uji diberikan dengan metode fix feeding rate sebanyak 10%/bobot biomassa/hari dan frekuensi pakan yang diberikan sebanyak 4 kali sehari. Hasil penelitian menunjukkan bahwa penambahan lisin pada pakan komersial berpengaruh sangat nyata (P<0,01) terhadap SGR, EPP, FCR, dan PER akan tetapi tidak berpengaruh nyata terhadap kelulushidupan udang vaneme. Dosis optimal asam amino lisin dalam pakan komersial udang vaname untuk SGR sebesar 2,33%, EPP sebesar 2,39%, FCR sebesar  2,37% dan PER  sebesar 2,09% menghasilkan SGR maksimal sebesar 4,72%/hari,  EPP maksimal sebesar 81,35%,   FCR maksimal sebesar 1,23, dan  PER maksimal sebesar 2,57.

The Cost

Growth and survival of Clarias gariepinus juveniles fed with a local feed and coppens commercial feed were observed for 16 weeks at  the laboratory of the Department of Zoology, University of Ilorin, Nigeria. The proximate compositions and economics of the feeds and the water quality of the cultured tanks were assessed. Fish fed with coppens showed significant (P<0.05) higher weight increase, specific growth rate, protein efficiency ratio and low food conversion ratio than fish fed with local feed. Significant (P<0.05) higher mortality were recorded in fish fed with the local feed. The growth performance was a reflection of the proximate composition of the feeds with local feed having low crude protein (10.95%), lipid (3.95%) and ash (4.92%) when compared to coppens which had 42% crude protein, 12% lipid and 9.5% ash with protein being most significant. Carbohydrate (69.90%) and crude fiber (2.88%) were higher in the local feed than in coppens with an imbalance in carbohydrate and lipid ratio. Mortality was attributed to stress resulting from the poor quality of the feed. Cost of feeding with local feed to a weight gain of 31.67g was ₦80, while the cost of feeding with coppens to a weight gain of 148.58g was ₦16.

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

The study was conducted to assess the growth and survival of <em>Macrobrachium rosenbergii</em> in earthen culture ponds in order to know about the growth potential of <em>M. rosenbergii</em> in mono as well as polyculture conditions in Jammu. Polyculture experiments of prawn with some selected carps Indian Major Carps (<em>Cirrhinus mrigala</em> and <em>Labeo rohita</em>) and Exotic Carps (<em>Cyprinus carpio</em>) were undertaken in 3 freshwater ponds for duration of 4 months. Under the monoculture conditions, prawns attained an average size of 10.40 ± 0.17 cm weighing 23.84 ± 0.32 g in 4 months and the survival rate was found to be more than 75%. The growth rate of prawns was found to increase steadily during the first half (upto mid-October) after which a decline in the growth rate was evident as the mean temperature reached below 18°C. In the polyculture ponds the prawns attained an average size of 10.10 ± 0.03 cm weighing 18.39 ± 0.89g (without<em> C. carpio</em>) and 8.4 ± 0.36 cm weighing 15.23 ± 0.36 g (with <em>C. carpio</em>) in 4 months and their survival rate was less than 70%. Prawns being benthic feeders utilized the leftover food (of the fishes) that settled at the bottom, therefore, saving the feed cost. It was observed that mean size of the fish attained in the polyculture practice was almost similar to that obtained in the monoculture. The ideal prawn polyculture should be practiced with fast growing compatible carps such as Rohu and grass carp. Bottom feeder carps such as Mrigal (<em>C. mrigala</em>) should be avoided in prawn polyculture practice as they compete with prawns in feeding.

Purpose The purpose of this study was to investigate the effect of a dietary probiotic on the growth performance and survival rate of Litopenaeus vannamei shrimp. Furthermore, the microbial quality of shrimp was evaluated. Design/methodology/approach Shrimp were divided into treatment and control groups (each group containing 45 shrimp). They were fed for four weeks with a control diet alone or supplemented with a commercial probiotic (Protexin®). At the end of the trial, they were assessed for survival rate, weight gain, average daily gain and specific growth rate. Samples of tail meat were also provided aseptically from peeled shrimp for bacteriological analysis including the count of Staphylococcus aureus, enterococci, Clostridium perfringens, fecal coliform, Salmonella, Escherichia coli, Listeria monocytogenes and total bacterial count. Findings The growth performance of the probiotic-treated group significantly (p < 0.05) increased at the end of the experimental period. However, no significant differences were observed for the survival rate between the groups (p > 0.05). The count of C. perfringens and the total bacterial count in shrimp supplemented with the probiotic were significantly lower than those of controls (p < 0.05). The count of coliforms and S. aureus was not significantly different between the groups (p > 0.05). Originality/value It could be concluded that the probiotic bacteria have the potential to stimulate the growth performance of L. vannamei. They can also be used for biological control of food-borne pathogens and improve the microbial quality and safety of shrimp at the farm level.

<p>This research was conducted to determine natural food substitution time by artificial diet   after salinity acclimatization from 20 ppt until 2 ppt, which can increase survival and growth of (<em>Litopenaeus vannamei</em>) postlarvae during rearing period. Design experiment was completely randomized design with five treatments and three replications of natural food <em>Chironomus</em> sp.  (60% of crude protein) substitution time by artificial diet (40% of crude protein) at day: 1 (A), 7 (B), 14 (C), 21 (D) and full natural food without artificial diet (E) during 28 days rearing period. White shrimp postlarvae and rearing media in this experiment based from best result of earlier research that is PL<sub>25 </sub>from acclimatization in media 2 ppt with addition of potassium 25 ppm to freshwater media.  The densities of PL<sub>25</sub> white shrimp were 20 PLs/50 liters of 2 ppt media. The result of this experiment showed that the use of artificial diet as soon as after salinity acclimatization (PL<sub>25</sub>) gave best performance production compared to which only that was given natural food <em>Chironomus</em> sp. during experiment or with treatment by artificial diet substitution at day-7, day-14 or day-21, shown with the highest value of food consumption level, protein retention, energy retention, daily growth rate and food efficiency. Survival rate of PL<sub>54</sub> was above 80% and not significant different between treatment. That is supported by chemical-physical value of water quality still in range appropriate to survival rate of white shrimp post larvae during a rearing period. The result of this experiment indicated that requirement nutrient of PL<sub>25</sub> in low salinity did not fulfilled if only rely on natural food, so that require artificial diet with nutrition content to support growth and survival rate of white shrimp post larvae more maximal.</p> <p>Key words: salinity, natural food, artificial diet, Pacific white shrimp</p> <p> </p> <p>ABSTRAK</p> <p>Tujuan penelitian ini adalah untuk menentukan waktu penggantian pakan alami oleh pakan buatan yang tepat selama masa pemeliharaan postlarva udang vaname di media bersalinitas rendah setelah melalui masa aklimatisasi penurunan salinitas dari 20 ppt hingga 2 ppt, sehingga dapat meningkatkan pertumbuhan dan kelangsungan hidup. Rancangan percobaan berupa rancangan acak lengkap dengan perlakuan yang diterapkan berupa waktu penggantian pakan alami <em>Chironomus </em>sp. (kadar protein 62%) oleh pakan buatan (kadar protein 40%) pada hari ke-1 (A), ke-7 (B), ke-14 (C), ke-21 (D) dan pakan alami (E) selama masa pemeliharaan. Postlarva udang vaname dan media pemeliharaan yang dipergunakan selama percobaan mengacu pada hasil terbaik yang didapatkan dari penelitian pendahuluan yaitu berupa PL<sub>25 </sub>hasil aklimatisasi di media bersalinitas 2 ppt  dengan penambahan kalium 25 ppm ke media air tawar pengencer. Padat tebar sebanyak 20 ekor/50 liter/wadah. Hasil percobaan menunjukkan bahwa pemberian pakan buatan yang diberikan segera setelah masa aklimatisasi salinitas (pada awal pemeliharaan PL<sub>25</sub>) memberikan performa produksi budidaya terbaik bila dibandingkan dengan yang hanya diberi pakan alami selama masa pemeliharaan maupun waktu penggantian pakan alami oleh pakan buatan pada hari ke-7, ke-14 dan hari ke-21 yang ditunjukkan dengan tingkat konsumsi pakan, retensi protein, retensi energi, laju pertumbuhan harian dan efisiensi pakan yang tertinggi.  Kelangsungan hidup di akhir pemeliharaan (PL<sub>54</sub>)  di atas 80% dan tidak berbeda nyata antar perlakuan. Hal ini ditunjang oleh nilai fisika kimia air yang berada dalam kisaran yang layak selama masa pemeliharaan. Hasil percobaan ini menunjukkan bahwa kebutuhan nutrisi pada stadia PL<sub>25</sub> di media bersalinitas rendah tidak terpenuhi jika hanya mengandalkan pakan alami sehingga perlu ditunjang dari pakan buatan dengankandungan nutrisi yang dapat mendukung pertumbuhan dan kelangsungan hidup yang lebih maksimal.</p> <p>Kata kunci: salinitas, pakan alami, pakan buatan, udang vaname.</p>
