Abstract

ABSTRACT

The aim of this research was to determine optimum stocking density for growing-out of spiny lobster Panulirus sp. in controlled tanks that conducted for 30 days. The experimental spiny lobsters have the initial average weight of 130.39 ± 0.32 g and initial average total length of 140.70 ± 0.06 mm. This study used completely randomized design with three different stocking densities (KT10: 10 ind/m3; KT18: 18 ind/m3; and KT26: 26 ind/m3) and two replications. The parameters observed in this study included water quality (temperature, pH, salinity, dissolved oxygen, and total ammonia nitrogen), physiological responses (total haemocyte count, haemolymph glucose, and frequency of molt), and production performances, such as growth, specific growth rate, feed conversion ratio, and survival rate. The results showed that the spiny lobster could be reared in high stocking density in controlled tanks. Water quality during the study in each treatment was; temperature 26.56–28.65oC, salinity 29.7–33.6 g/L, pH 7.5–8.5, dissolved oxygen 6.15–6.58 mg/L, and total ammonia nitrogen 0.11–0.34 mg/L. The best stocking densities for spiny lobster was 18 ind/m3 (KT18) with 2.5‒3.5×106cells/mL total haemocyte counts, 24.6‒28.3 mg/dL haemolymph glucose, and 38.37 ± 3.20% frequency of molt. The final average body weight and length were 145.06 ± 0.42 g and 142.77 ± 0.19 mm, respectively. The survival rate reached 86.11 ± 3.92% with a specific growth rate 0.35 ± 0.01%/day, and feed conversion ratio 7.87 ± 0.31.

Keywords: high stocking density, Panulirus sp., physiological responses, productivity.

 

 

ABSTRAK

Tujuan dari penelitian ini adalah untuk menentukan kepadatan terbaik dalam pembesaran lobster laut Panulirus sp. yang dipelihara dalam bak terkontrol selama 30 hari. Lobster laut yang digunakan pada awal penelitian memiliki bobot 130,39 ± 0,32 g dan panjang total 140,70 ± 0,06 mm. Penelitian dilakukan menggunakan rancangan acak lengkap dengan tiga perlakuan kepadatan berbeda, yaitu: 10 ekor/m3(KT10), 18 ekor/m3(KT18), dan 26 ekor/m3(KT26) dan dua ulangan. Parameter uji yang diamati dalam penelitian ini meliputi kualitas air (suhu, salinitas, pH, DO, dan TAN), respons fisiologis (total hemosit/THC, glukosa hemolim, dan frekuensi pergantian kulit), dan kinerja produksi meliputi pertumbuhan, laju pertumbuhan spesifik, rasio konversi pakan, dan tingkat kelangsungan hidup. Hasil penelitian menunjukkan bahwa lobster laut dapat dibesarkan dengan kepadatan tinggi dalam bak terkontrol. Pengukuran nilai kualitas air pada setiap perlakuan selama pemeliharaan adalah suhu berkisar 26,56–28,65oC, salinitas 29,7–33,6 g/L, pH 7,5–8,5, DO antara 6,15–6,58 mg/L dan TAN antara 0,11–034 mg/L. Perlakuan terbaik selama penelitian adalah dengan kepadatan 18 ekor/m3 (KT18) dengan nilai THC berkisar antara 2,5–3,5×106  sel/mL, glukosa hemolim 24,6–28,3 mg/dL,dan frekuensi pergantian kulit 38,37±3,20%. Bobot dan panjang lobster akhir rata-rata pada perlakuan tersebut masing-masing mencapai 145,06 ± 0,42 g, dan 142,77 ± 0,19 mm. Tingkat kelangsungan hidup mencapai 86,11 ± 3,92% dengan laju pertumbuhan spesifik 0,35 ± 0,01%/hari dan rasio konversi pakan selama penelitian adalah 7,87 ± 0,31.

Kata kunci: padat pemeliharaan, Panulirus sp., produktivitas, respons fisiologis.
