Abstract

Sebagai upaya untuk mempertahankan keanekaragaman hayati perairan, pemerintah Indonesia telah meratifikasi Cites dan membawa konsekuensi pada pengendalikan dan pengawasan atas perdagangan tumbuhan dan satwa liar termasuk jenis ikan yang masuk dalam Appendiks CITES. Loka Pengelolaan Sumberdaya Pesisir dan Laut Sorong merupakan salah satu UPT Kementerian Kelautan dan Perikanan yang bertugas melaksanakan pengendalian peredaran dan pemanfaatan ikan dilindungi. Tujuan dari penelitian ini adalah untuk mendeskripsikan tentang pengaturan dalam pemanfaatan jenis ikan dilindungi dan kontribusi penerimaan PNBP. Penelitian menggunakan metode deskriptif kualitatif dimana pengumpulan data dilakukan melalui pencatatan dan wawancara pada kurun waktu tahun 2023 memberikan hasil bahwa pelaksanaan pengendalian dilakukan dengan menerbitkan izin dalam bentuk surat rekomendasi untuk peredaran dalam negeri dan luar negeri serta surat angkut jenis ikan. Rekomendasi dalam negeri diberikan untuk 551.545,16 kg yang merupakan hiu daging, 27.021,96 kg hiu kulit, 70.524,39 kg hiu sirip, 696,30 kg hiu tulang, 89.984,47 pari daging, 4.600,00 kg pari kulit, 177.428,25 teripang dan 504,00 pcs soft coral. Pada rekomendasi luar negeri diberikan untuk 188,64 kg hiu sirip dan 420,60 kg teripang. Sedangkan untuk surat angkut jenis ikan dalam negeri diberikan terhadap 150.526,13 kg hiu, pari dan sidat, dan untuk 74.677 ekor arawana dan napoleon. Keseluruhan ikan yang diedarkan dan dimanfaatkan tidak termasuk jenis ikan yang dilindungi penuh oleh pemerintah. Nilai total PNBP yang diperoleh atas pemanfaatan dan peredaran jenis ikan Rp1.647.742.781,00 PNBP.

Abstract

Excessive feeding not only increases production costs, but also it can pollute the environment due to unconsumed feed residue. One of the strategies that can be used to increase aquaculture efficiency is by implementing restricted feeding techniques. This study aimed to evaluate the impact of different restricted feeding intervals on tilapia growth performance, feed conversion ratio (FCR), survival rate (SR), and feed cost efficiency. This study used a Completely Randomized Design (CRD). The study consisted of three treatments and four replications using one container separated using net partition in a pond with a rearing period of 50 days. Periodic restricted feeding affected the growth of tilapia length and weight, but did not affect Survival Rate (SR) and Feed Conversion Ratio (FCR). The highest rate of growth was shown by P2 (restricted feeding period of 1 day) with a length of 8.79 3.18 cm and a weight of 9.46 3.18 g, and the lowest rate of growth was in treatment P3 (restricted fasting period of 2 days) with a length of 8.2 1.82 cm and a weight of 7.47 2.45 g. Although FCR and SR did not differ significantly across treatments, P2 had the lowest FCR (0.76) and highest SR (83%), with a 23% reduction in feed cost compared to P1. In conclusion, restricted feeding with one fasting day per week improved tilapia growth and feed utilization efficiency, offering a cost-effective and sustainable feeding strategy for aquaculture.Keywords:TilapiaGrowthFeed conversion ratioSurvival rateCompletely randomized design
