Abstract

Ikan klon hitam (Amphiprion percula) sering juga disebut klon biak merupakan salah satu ikan hias laut yang memiliki nilai ekonomi tinggi yang dapat memijah dalam akuarium. Tujuan penelitian ini adalah untuk mengetahui beberapa aspek biologi reproduksi ikan klon hitam pada kondisi pemeliharaan akuarium. Sepasang induk dengan panjang total 4-9 cm diperlihara dalam akuarium ukuran 60x40x30 cm3. Jumlah induk yang digunakan sebanyak 18 pasang, setiap akuarium satu pasang induk. Pakan yang diberikan pertama-tama pakan buatan kemudian satu jam berikutnya pakan campuran jembret dan kopepoda sampai kenyang dengan frekuensi 2 kali sehari. Variabel yang diamati adalah ukuran induk, jumlah, dan derajat tetas telur. Hasil penelitian menunjukkan bahwa induk ikan betina memijah pada kisaran panjang 6,8-9,5 cm sedangkan jantan pada kisaran panjang 4,6-6,2 cm. Rata-rata jumlah telur per pemijahan sangat bervariasi yaitu 423±255 telur dengan frekuensi rata-rata 2,74 ± 0,38 kali/bulan. Pemijahan induk secara parsial dengan frekuensi maksimum 4 kali/bulan. Induk dengan ukuran 9,5 cm masih dapat aktif memijah dengan frekuensi 3 kali/bulan. Pasangan induk dapat menghasilkan jumlah telur di atas 700 telur/pemijahan. Penelitian ini juga menunjukkan bahwa induk ikan klon hitam dapat memijah sepanjang tahun di akuarium dengan jumlah telur dan frekuensi pemijahan yang bervariasi antar individu dan antar periode pemijahan. Derajat tetas rata-rata telur selama penelitian adalah 79,72±13,73 % dengan jarak waktu dari pemijahan pertama ke pemijahan berikutnya antara 7-14 hari.Kata kunci: Reproduksi, ikan klon hitam, Amphiprion percula, derajat tetas

Abstract

ABSTRACT Feed management is a critical factor in the nursery activities because food serves as an energy for growth and survival rates. The study aimed to determine the best feeding to improve growth and survival rates. Cultured of coral trout grouper seeds were used for this research in 9 fiber tubs each of  0.8 tonnes of sea water volume with 3 treatments and 3 replicates. The feeding treatments were (a) commercial feeding pelle; (b) trash fish; and (c) feeding combinations (50% pellets and 50% trash fish). The initial length of coral trout grouper seeds were 3 cm long. The pellet used was a commercial pellet with dose of 5-10% biomass, while the trash fish was clupeid fish. Feeding times were twice a daya at 08:00 and 16:00 local time. A complete random design was used as an experiment design. Data was analysed using ANOVA and descriptive statistics. Water qualities during larva rearing included water temperature, pH, salinity, DO, ammonia, nitrite, and phosphate. The results showed that growth dan survical rates was significantly affected by combination feeding method (50% pellet and 50% trash fish) with growth rate of 0.08% cm/day and survival rate of 60.20±2.34%. Keywords: Feed, trash fish, juvenile coral trout grouper, growth, and survival.

Abstract

The information about the optimum and tolerable salinity to support in the success of coral trout grouper’s seed culture is still limited until now. The aim of this study was to understand the effect of different salinity on growth, survival, feed conversion (FCR) and the profile of blood (hematocrit and hemoglobin) of coral trout grouper seed. The seed with total length 6.0 ± 0.5 cm and body weight 3.2±0.3 g were used as tested animals. Five different salinity treatments, namely: 10±1 ppt (A), 16±1 ppt (B), 22±1 ppt (C), 28±1 ppt (D), and the sea water (34 ppt) as a control (E) were undertaken in this study, with three replications for each treatment. Salinity values were reach by adding freshwater into the tested seawater. Water changing system in this study was performed in recirculation process, with 25% of water replacement every 7 days. The result of this study showed that the survival rate values were 100% for all treatments, indicating that coral trout grouper seed can be cultured in the range of salinity between 10 to 34 ppt.  The highest total length and body weight were recorded from treatment C (22 ppt), as well as noted to gain the lowest FCR. Correspondingly, the seed in treatment C also founded to have in the greatest amount of hematocrit and hemoglobin. Optimum salinity for rearing of coral trout grouper seeds  with  total length 6 cm was 22 ppt.  Keywords: salinity, growth, survival rate, feed conversion, blood profile

Abstract

Ikan kerapu raja sunu (Plectropomus laevis) merupakan komoditas ekspor yang bernilai ekonomis tinggi di pasar Asia, namun stoknya di alam sudah langka. Pemberian pakan buatan dalam pemeliharaan larvanya telah dilakukan, namun waktu respon awal larva terhadap pakan buatan secara tepat belum diketahui. Penelitian ini bertujuan untuk mengetahui waktu awal pemberian pakan buatan yang efektif pada pemeliharaan larvanya. Tiga perlakuan pemberian pakan buatan yang diuji yaitu mulai umur 7 hari (D-7) (A), D-10 (B), dan D-13 (C). Parameter yang diamati meliputi perkembangan panjang total, sintasan larva, jumlah rotifer dalam lambung dan histologi organ pencernaan larva. Penelitian berlangsung sampai larva berumur 43 hari, menggunakan rancangan acak kelompok (RAK) dengan tiga kelompok waktu untuk setiap perlakuan. Hasil penelitian menunjukkan bahwa perbedaan waktu awal pemberian pakan buatan berpengaruh terhadap sintasan dan pertumbuhan larva. Panjang total dan sintasan larva umur 43 hari yang tertinggi dicapai pada perlakuan B yaitu 29,3 mm ± 0,36 mm dan 2,61% ± 0,21%; diikuti oleh perlakuan C dengan nilai 28,0 mm ± 0,85 mm dan 1,55% ± 0,18%; dan yang terendah pada perlakuan A adalah 27,0 mm ± 0,25 mm dan 0,85% ± 0,13%. Data ini menunjukkan bahwa waktu awal pemberian pakan buatan yang terbaik adalah mulai larva berumur 10 hari.
