Abstract

The aim of this study to observe the reproductive performance and larval development of white shrimp broodstock with adequate feed and water quality control programs. The stages of research were preparation of cultivation media, selection of broodstock, spawning, hatching and rearing of larvae. The broodstock that were spawned came from Hawaii with a weight of 35 g/ind for the male broodstock and 40 g/ind for the female broodstock. The broodstock were fed with marine worms and squid. The larvae were given natural diet in the form of Artemia salina, Thallassiosira sp. and Skeletonema costatum and artificial feed. The results showed that the reproductive performance of the broodstock was observed with the number of eggs 102.400.000 eggs from 667 broods, the average fecundity per broodstock were 143.986 eggs, the number of naupli was 75.520.000 individuals, the hatching rate was 60.9%. Larval development starts from the egg stage which undergoes embryogenesis, hatches into naupli 1-6, then becomes zoea 1-3, mysis 1-3 and post-larvae (PL). Length growth from PL1-PL8 was 3.95-8.05 mm with a survival rate of 43.95%. Water quality during rearing is still in the optimum range for the growth of broodstock and shrimp larvae.

Abstract

Peningkatan produksi dalam upaya memenuhi permintaan pasar ekspor berdampak pada peningkatan permintaan benih udang vaname. Benih udang dari alam hanya dapat memenuhi 20% dari total kebutuhan tambak udang, sedangkan kekurangan 80% diharapkan dari produksi benih pada kegiatan pembenihan. Penelitian ini bertujuan untuk menganalisis aspek ekonomi dari kegiatan pembenihan udang vaname. Tempat penelitian dilakukan di PT. Kawan Kita Kultur Persada, Kabupaten Situbondo, Jawa Timur. Metode penelitian dilakukan dengan observasi langsung di perusahaan. Data yang diperoleh dianalisis menggunakan persamaan untuk menghitung pendapatan, laba, titik impas (BEP), R/C ratio dan payback period (PP). Hasil penelitian menunjukkan bahwa modal usaha investasi yang digunakan sebesar Rp 2.666.905.000 dengan biaya tetap per siklus sebesar Rp 204.353.899, biaya variabel per siklus sebesar Rp 85.367.125. Total pendapatan per siklus Rp 783.890.000, total pendapatan per tahun Rp 3.135.560.000, laba per siklus adalah Rp 494.168.976, laba per tahunan Rp 1.976.675.904, BEP produksi 8.697.719 ekor dan BEP harga Rp 325.529.240,44, R/C rasio 2,7 dan payback period 5,9 siklus. Kajian ini menunjukkan bahwa kegiatan pembenihan udang vaname di lokasi tersebut layak untuk dikembangkan.
