Vannamei shrimp (Litopenaeus vannamei) is one of the leading fishery products of the fisheries sector. The problem that is often found in the failure of vannamei shrimp productions is the high level of mortality due to the nature of cannibalism during molting. One solution to minimize the cannibalism of vannamei shrimp is to provide tryptophan supplements in a feed. Tryptophan is a type of essential amino acid that serves as a precursor for serotonin biosynthesis. This study aims to determine the effect and optimal dose of tryptophan added to feed to reduce cannibalism and growth of vannamei shrimp. The test fish used in this study were vannamei shrimp with an average weight of 0,81 ± 0,26 g/individual.  This study used an experimental method, a completely randomized design (CRD) consisting of 4 treatments and three replications. The test feed used in this study was artificial feed with a protein content of 38% plus tryptophan according to treatments A (0%/kg feed), B (0.75%/kg feed), C (1.5%/kg feed), and D (2.25%/kg feed). The results showed that the addition of Tryptophan in the feed had a noticeable effect (P<0,05) on cannibalism levels, survival, and molting rates but had no significant effect (P>0,05) on absolute weight growth, specific growth rates, efficiency ratios protein and efficiency feed utilization of vannamei shrimp. The best dose of tryptophan addition in feed to lower the rate of vannamei shrimp cannibalism in this study was 2,25%, capable of producing a cannibalism rate of 13,33%. Udang vaname (Litopenaeus vannamei) merupakan salah satu produk perikanan unggulan sektor perikanan. Permasalahan yang sering ditemukan dalam kegagalan produksi udang vaname adalah tingginya tingkat mortalitas karena adanya sifat kanibalisme pada saat terjadi molting. Solusi untuk meminimalisir kanibalisme udang vaname adalah dengan memberi suplemasi asam amino pada pakan, salah satunya adalah triptofan. Triptofan merupakan salah satu jenis asam amino esensial yang berfungsi sebagai prekursor untuk biosintesis serotonin. Penelitian ini bertujuan untuk mengkaji pengaruh dan dosis optimal triptofan yang ditambahkan ke dalam pakan untuk menurunkan tingkat kanibalisme dan pertumbuhan udang vaname. Ikan uji yang digunakan pada penelitian ini adalah udang vaname dengan bobot rata-rata 0,81±0,26 g/ekor. Penelitian ini menggunakan metode eksperimen, rancangan acak lengkap (RAL) yang terdiri atas 4 perlakuan dan 3 kali ulangan. Pakan uji yang digunakan dalam penelitian ini adalah pakan buatan dengan kandungan protein 38% ditambah triptofan sesuai perlakuan yaitu : A (0%/kg pakan), B (0,75%/kg pakan, C (1,5%/kg pakan), dan D (2,25%/kg pakan). Hasil penelitian menunjukkan bahwa penambahan triptofan dalam pakan berpengaruh nyata (P<0,05) terhadap tingkat kanibalisme, kelulushidupan dan tingkat molting, namun tidak berpengaruh nyata (P>0,05) terhadap pertumbuhan bobot mutlak, laju pertumbuhan spesifik, protein efisiensi rasio dan efisiensi pemanfaatan pakan. Dosis terbaik dari pemberian triptofan dalam pakan untuk menurunkan tingkat kanibalisme udang vaname dalam penelitian ini adalah 2,25%, mampu menghasilkan tingkat kanibalisme sebesar 13,33%.

Udang vaname (Litopenaeus vannamei) adalah karnivora yang sukar mencerna protein nabati dalam pakan sehingga efisiensi pemanfaatan pakan belum maksimal.  Hampir 40-60% dari total biaya produksi hanya untuk biaya pakan. Efisiensi pemanfaatan pakan dapat ditingkatkan dengan penambahan enzim papain dalam pakan yang mampu meningkatkan penguraian dan pencernaan bahan pakan yang mengandung protein nabati sederhana sehingga dapat meningkatkan daya cerna protein pakan. Penelitian ini bertujuan mengkaji pengaruh suplementasi enzim papain dalam pakan terhadap efisiensi pemanfaatan pakan, performa pertumbuhan dan kelulushidupan udang vaname. Hewan uji berupa udang vaname dengan bobot rata-rata 3,02±0,21 g/ekor yang diperoleh dari pembudidaya udang vaname Desa Blebak, Kecamatan Mlonggo, Jepara.  Metode dalam penelitian ini adalah metode eksperimen, dengan Rancangan Acak Lengkap, 4 Perlakuan dan 3 kali pengulangan. Terdapat 4 perlakuan suplementasi enzim papain dalam pakan yaitu A (0 %), B (0,1 %), C (0,2 %), dan D (0,3 %). Parameter yang diamati meliputi EPP, PER, RGR, SR dan parameter kualitas air. Hasil penelitian menunjukkan bahwa penambahan enzim papain dalam pakan meningkatkan EPP, PER, RGR, namun tidak berpengaruh pada SR udang vaname. Enzim papain sebesar 0,1%/kg pakan merupakan dosis optimal pada EPP, PER dan RGR menghasilkan nilai maksimal sebesar 66,51%, 1,64 dan 4,22%/hari. White shrimp (Litopenaeus vannamei) is a carnivorous animal that difficult to digests vegetable protein in the feed so that the efficiency of feed utilization is not maximal. Nearly 40-60% of the total production cost is only for feed cost. Feed efficiency is improved by using papain in the feed which can increase the breakdown and consumption of feed containing vegetable protein so that it can easily increase the digestibility of feed protein. This study examines the effect of papain supplementation in feed on the growth performance, efficiency of feed utilization, and survival rate of white shrimps. The test animals were white shrimp with an average weight of 3.02 ± 0.21 g / individuals obtained from the whiteleg shrimp farmers in Blebak Village, Mlonggo District, Jepara. The method in this study was an experimental method, with a completely randomized design, 4 treatments, and 3 repetitions. There were 4 supplements of papain in feed: A (0%), B (0.1%), C (0.2%), and D (0.3%). The parameters were EPP, PER, RGR, SR, and water quality parameters. The results showed that the supplementation of the papain in feed increased the EPP, PER, RGR, but had no effect on the SR of white shrimp. Papain of 0.1% / kg of feed was the optimal dose at EPP, PER, and RGR resulting in a maximum value of 66.51%, 1.64 and 4.22% / day.

Chitosan is an ingredient that can be used as a feed additive. In aquaculture, chitosan can be used as an antimicrobial, antifungal, antioxidant growth-promoting and immunostimulant. This study aims to determine the optimum addition of chitosan to feed to increase growth and daily feed consumption of giant gourami. The method used in this research is an experimental method using a completely randomized design (CRD), which consists of five treatments and three replications. The treatments used were (A) without chitosan (control), (B) 2.5 g/kg feed, (C) 5 g/kg feed, (D) 7.5 g/kg feed, and (E) giving chitosan of 10 g/kg feed. The test fish used were giant gourami with a 6 – 8 cm length and a weight of 8 – 10 g. The container used was hapa measuring 1 x 1 x 1 m3 with a density of 15 fish per treatment and 42 days of maintenance. The feeding rate was 3% of the fish biomass. Data from observations of length and weight were analyzed using Analysis of Variance (ANOVA) with a 95% confidence level; if there was a significant difference, Duncan's multiple distance test was performed. The results showed that addition of chitosan 7.5 g/kg feed was effective in improving growth on giant gourami. During maintenance, absolute length growth was 2.90 ± 0.10 cm, absolute weight growth was 15.33 ± 1.19 g, daily growth was 36.51 ± 2.84%, feed conversion ratio was 1.69 ± 0.06, and survival rate was 100 ± 0.00%. This research concluded that the optimum level of addition of chitosan to increase growth and daily feed consumption of giant gourami was 7.5 g/kg feed.Keywords:ChitosanFeed additiveGiant gouramiGrowth
