Laju Pengosongan Lambung, Komposisi Kimia Tubuh, Glikogen Hati dan Otot, Molting, dan Pertumbuhan Kepiting bakau pada Berbagai Persentase Pemberian Pakan dalam Budidaya Kepiting Cangkang Lunak

摘要

AbstrakudEfisiensi dalam budidaya kepiting cangkang lunak sangat ditentukan oleh jumlah pakan yang tepat. Penelitian ini bertujuan menentukan persentase pakan buatan yang tepat dalam budidaya kepiting cangkang lunak berdasarkan laju pengosongan lambung, komposisi kimia tubuh, kadar glikogen hati dan otot, persentase molting dan pertumbuhan kepiting bakau. Desain penelitian menggunakan Rancangan Acak Lengkap dengan tiga perlakuan persentase pemberian pakan (2, 4, dan 6% bobot badan per hari). Pakan diberikan dengan komposisi protein 30,86%, lemak 7,2%, BETN (Bahan Ekstrak Tanpa Nitrogen) 48,89%, serat kasar 5,7% diperkaya dengan 0,10415 mg vitomolt/g pakan untuk dosis standar dan 0,4166 mg vitomolt/g pakan untuk dosis tinggi atau setara dengan 700 ng vitomolt/g kepiting. Kepiting uji Scylla sp. dipelihara dalam crabs box secara individu dan diletakkan di tambak. Berdasarkan parameter laju pengosongan lambung, komposisi kimia tubuh, meliputi protein, lemak, serat kadar, BETN, abu, dan energi, kadar glikogen hati dan otot, persentase molting, dan pertumbuhan pemberian pakan dalam budidaya kepiting cangkang lunak dapat dilakukan dengan persentase 2-4% bobot badan perhari.udududAbstractudEfficiency in the soft shell crabs cultivation is determined by the number of correct feed. This study aims to determine the exact percentage of artificial feeding in the soft shell crabs cultivation based on the rate of gastric evacuation, chemical body composition, liver and muscle glycogen levels, the percentage of molting and growth of mud crabs. Research design using a completely randomized design with three treatments percentage feeding (2, 4, and 6% of body weight per day) feed is given to the composition of 30.86% protein, 7.2% fat, NFE (Nitrogen Free Extract) 48.89%, crude fiber 5,7% enriched with vitomolt 0.10415 mg / g of feed to the standard dose vitomolt and 0.4166 mg / g of feed for high-dose or vitomolt equivalent to 700 ng / g crab. Tests crabs Scylla sp. reared in individual box and placed in the pond. Based on the rate of gastric evacuation parameters, the chemical body composition, including protein, fat, fiber content, NFE, ash, and energy, liver and muscle glycogen levels, the percentage of molting, and growth feeding in soft shell crabs cultivation can done with the percentage of 2-4% of body weight per day.
