Abstract

ABSTRACT

 

This study aimed to determine optimum stocking density of mud crab Scylla serrata through the applied of different stocking density in every treatment in recirculation system. Experimental design used was complete randomized design (CRD) with three density treatments which were 5 (P1), 10 (P2), and 15 ind/container (P3). All treatments replicated three times. The crab with the average of body weight 150 g/ind cultured in a plastic box (40×30×30 cm). Crab was cultured within 60 days and were fed two times a day by at satiation method. The result showed that P2 treatment gave the best result of mangrove crabs production performance among all treatments with 73.33±5.77% survival rate, 0.68±0.01 g/ind/day absolute growth rate and food conversion ratio 10.11±0.01. Treatment P1 gave the good response of stress, it indicated by the lowest glucose of all tretamnets at the level of 31.91 mg/dL in the end of treatment periods. The water quality during study period was fluctuative as affected by different stocking density in the treatments.

ABSTRAK

 

Penelitian ini bertujuan untuk menentukan padat tebar optimal kepiting bakau Scylla serrata melalui penerapan kepadatan tebar yang berbeda pada setiap perlakuan dalam sistem resirkulasi. Rancangan penelitian yang digunakan adalah rancangan acak lengkap dengan tiga perlakuan yaitu 5 (P1), 10 (P2), dan 15 ekor/wadah pemeliharaan (P3) dengan tiga ulangan. Kepiting bakau yang digunakan memiliki berat rata-rata 150 g/ekor. Wadah pemeliharaan yang digunakan selama pemeliharaan adalah kontainer plastik yang berukuran 40×30×30 cm. Pemeliharaan kepiting bakau dilaksanakan selama 60 hari dan diberikan pakan berupa ikan rucah dua kali sehari secara at satiation. Penelitian menunjukkan bahwa perlakuan P2 memberikan hasil kinerja produksi terbaik dibandingkan perlakuan lainnya dengan nilai kelangsungan hidup 73,33±5,77%, laju pertumbuhan mutlak 0,68±0,01 g/ekor/hari, dan rasio konversi pakan 10,11±0,01. Perlakuan P1 menunjukkan respons stres yang baik dengan memiliki nilai kadar glukosa paling rendah dari perlakuan lain yaitu 31,91 mg/dL pada akhir masa pemeliharaan. Kualitas air selama penelitian memiliki nilai yang fluktuatif di setiap perlakuan sebagai efek adanya perbedaan jumlah padat tebar setiap wadahnya
