ABSTRACTSnakehead Channa striata is a local specific fish species and has high economic value. Until now the production of snakehead still reelies on the catch of nature because cultivation of snakehead is still underdeveloped. The main constraint in snakehead fish farming is high mortality on snakehead juvenile rearing phase. This study was conducted to determine the best stocking density on snakehead juvenile rearing to achieve optimal production. The treatments used in this study were stocking density of 1 juvenile/L, 2 juveniles/L, and 3 juveniles/L. Snakehead juveniles with a length of 3.41 ± 0.39 cm and weight 0.28 ± 0.07 g, were reared for 42 days in the aquarium sized 40×40×40 cm with a volume of 40 L. Fishes were fed by bloodworms in ad libitum method. The result showed that the treatments did not affect the survival, growth and the ratio of RNA/DNA of snakehead juvenile. Survival of juvenile snakehead ranged 92.5‒94.58% (P>0.05). The result of water quality measurement showed that it was on optimum condition to supporting snakehead growth at 3 juveniles/L stocking density. Furthermore, recirculation can be use to maintenance water quality for optimum condition. Thus, the rearing of snakehead fish juvenile in the recirculation system can use a stocking density of 3 juveniles/L, and the recirculation system could maintain the water quality in good condition.

ABSTRACT Intermediate and holding rearing of botia face several problems such as the limited land, water quality, and decreased growth. The application of a recirculation culture system using the blood clam filter is increased to water quality and expected to solve the problems. This study aimed to analyze the production performance of botia fish on intermediate and holding rearing in the recirculation system by utilizing blood clams as the filter. This study used a factorial completely randomized design with two factors; clam particle sizes (1 mm, 2 mm, and 3 mm) and dosages (1.4 g/L, 1.8 g/L, and 2.2 g/L). Every experiment was conducted in three replication. The aquarium used in this study was 40×40×60 cm3. The size of fish samples was 3.5 ± 0.5 cm with the stocking density (3 fish/L, each test aquarium). The recirculation system was applied seven days before the fish were stocked. Every 15 days, weight and length of fish were measured (for 60 days). The results of physical (temperature) and chemical (pH, dissolved oxygen, ammonia dan nitrite) water quality in the recirculation system using the blood clam filter showed good conditions for botia fish. The stress response of botia blood glucose and TKO fluctuates with environmental changes. Mineral water and fish produced by calcium, magnesium, and phosphorus increase until the end of maintenance. There is an interaction at TKH between particle size and the dose of blood shells, whereas, LMPW, LMPL, and RKP significantly different only the use of dose 2.2 g/L.

Penerapan sistem resirkulasi menggunakan cangkang darah dapat meningkatkan kualitas air dan kinerja produksi. Penelitian ini bertujuan menganalisis kinerja produksi budidaya ikan botia pada sistem resirkulasi dengan pemanfataan cangkang kerang darah sebagai bahan filter. Penelitian ini menggunakan rancangan acak lengkap faktorial dua faktor, yaitu ukuran partikel cangkang kerang darah (1 mm, 2 mm, dan 3 mm) dan dosis cangkang kerang darah (1.4g/L, 1.8g/L dan 2.2g/L). Setiap perlakuan dilakukan dengan tiga kali ulangan. Akuarium yang digunakan dalam penelitian berukuran 40×40×60 cm3. Ikan yang digunakan berukuran 3.5 ± 0.5 cm dengan padat tebar 3 ekor/L. Sistem resirkulasi dioperasikan selama tujuh hari sebelum ikan ditebar. Bobot dan panjang ikan diukur setiap 15 hari selama 60 hari pemeliharaan. Penelitian dalam sistem resirkulasi menggunakan cangkang kerang darah pada media filter menghasilkan kondisi kualitas air suhu, pH, oksigen terlarut, amonia dan nitrit air. Respons stres ikan berupa glukosa darah dan tingkat konsumsi oksigen (TKO) berfluktuasi seiring dengan perubahan lingkungan. Mineral air dan ikan yang dihasilkan meliputi kalsium, magnesium dan fosfos meningkat hingga akhir pemeliharaan. Parameter tingkat kelangsungan hidup (TKH) memiliki interaksi antara ukuran partikel dan dosis cangkang kerang darah, sedangkan untuk laju pertumbuhan bobot mutlak (LPMB), laju pertumbuhan panjang mutlak (LPMP) dan rasio konversi pakan (RKP) berbeda nyata dengan penggunaan dosis 2.2 g/L. Kata kunci: Cangkang kerang darah, ikan botia, pH, mineral, resirkulasi.
