The nutritional content of cacao pod husk consisted of 9,15% protein, 1,96 % lipid, 25,64 % crude fiber, 10,39% ash, and 52,86% nitrogen-free extract (NFE). Crude fiber from cacao pod husk was difficult to be digested by fish. The solution for that constraint was by applying fermentation proccess. This experiment was aimed to observe the influence of cacao pod husk flour which has been fermented first before added into the practical diets, on the feed efficiency and growth of carp (Cyprinus carpio). The trial fish used were carp (C. carpio) with an initial average body weight of 6,54 ± 0,07 g/fish. Feeding frequency applied was twice a day, i.e. at 08.00 a.m and 16.00 p.m. and by appliying an at satiation method. The fishes were cultured for 42 days with the stocking density of 1 fish/ 2L. The experimental method used was completely randomize design (RCD) with 4 treatments and 3 replicates. The treatment of A, B, C, and D were the trial diets with the concentration of cacao pod husk flour of 0, 10, 20, and 30%, respectively. The data measured were feed consumption, feed efficiency (FE), protein efficiency ratio (PER), growth (G), spesific growth rate (SGR), and survival rate (SR). The data showed that the use of fermented cacao pod husk flour in the diets resulted significant by effects (P<0,05) on the feed consumption, FE, PER,G, SGR, and SR.

One of the problems in hatching of silver barb is because the maturation period of gamete broodstock male and female fish does not happen together.

High sperm concentration can inhibit spermatozoa activity and affect sperm to find microphils. The addition of honey in dilute solution of physiological NaCl is expected to be able to improve the quality of sperm of silver barb. The aim this research was to know the effect and the best honey dosage in physiological NaCl on sperm quality of silver barb.

Solusi untuk menurunkan kandungan bahan organik yaitu menggunakan kerang hijau (Perna viridis) sebagai biofilter. Kerang hijau sebagai hewan filter feeder dapat mengasimilasi bahan organik. Penelitian ini bertujuan untuk mengkaji laju filtrasi kerang hijau dalam menurunkan kandungan bahan organik yang berasal dari kepadatan udang windu yang berbeda dan mengkaji pertumbuhan serta kelulushidupan udang windu yang dibudidayakan dengan air hasil filtrasi kerang hijau. Biota uji yang digunakan adalah udang windu post larva 45 kepadatan 40 ekor/m2 dan kerang hijau ukuran 3-4 cm kepadatan 30 ekor/m2. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) terdiri atas 3 perlakuan dengan 3 kali pengulangan, yaitu: A (kepadatan udang windu 20 ekor/m2), B (kepadatan udang windu 60 ekor/m2), dan C (kepadatan udang windu 100 ekor/m2). Hasil penelitian menunjukkan bahwa bahan organik dari kepadatan udang windu yang berbeda tidak berpengaruh nyata (P>0,05) terhahap laju filtrasi (FR) kerang hijau dalam menurunkan kandungan bahan organik. Air limbah hasil filtrasi kerang hijau tidak berpengaruh nyata (P>0,05) terhahap pertumbuhan dan kelulushidupan udang windu. Laju filrasi perlakuan A berkisar antara -1,83–1,31L/hari, perlakuan B -2,07–0,96 L/hari, dan perlakuan C -2,03–1,06 L/hari. Penurunan bahan organik perlakuan A sebesar 44,92 mg/L, perlakuan B 36,58 mg/L, dan perlakuan C 39,84 mg/L. Laju pertumbuhan relatif perlakuan A sebesar 12,32±1,02%, perlakuan B 12,46±0,81%, dan perlakuan C 13,68±1,28%. Kelulushidupan (SR) udang windu perlakuan A sebesar 92,50±6,61%, perlakuan B sebesar 76,67±11,81%, dan perlakuan C sebesar 95,83±3,82%.","PeriodicalId":21499,"journal":{"name":"Sains Akuakultur Tropis","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78408658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kegiatan budidaya kakap putih di Indonesia saat ini masih belum banyak berkembang, salah satu faktor yang menghambat kegiatan pembesaran kakap putih di Indonesia adalah masih sulitnya pengadaan pakan rucah secara berkelanjutan dalam jumlah yang cukup. Salah satu upaya kegiatan pembesaran ikan kakap putih yang dapat dilakukan adalah dengan media keramba jaring apung (KJA) dan penggunaan pellet sebagai ganti pakan rucah. Penelitian ini bertujuan untuk mengetahui performa pertumbuhan ikan kakap putih (Lates calcarifer) yang dibudidayakan dengan sistem keramba jaring apung (KJA). Hasil dari pengamatan performa pertumbuhan ikan kakap putih yang dibudidayakan dengan sistem KJA adalah nilai SGR 0,28%/hari, nilai pertumbuhan bobot mutlak 47 g, dan nilai kelulushidupan 82,5%.
