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

Pendederan kerapu banyak dilakukan di bak-bak semen dan hatchery, tetapi usaha pendederan juga dapat dilakukan di laut dengan menggunakan karamba jaring apung (KJA) maupun di tambak.  Penelitian ini bertujuan untuk menganalisa pertumbuhan, dan kandungan nutrisi pada kerapu sunu yang dipelihara pada lingkungan berbeda yaitu di KJA, tambak dan bak hatchery.  Benih ikan kerapu sunu berukuran panjang total 6,56±0,52cm dan berat 4,48±1,04 g dengan kepadatan 50 ekor/jaring dipelihara dalam jaring berukuran 1mx1mx1m dengan ukuran mata jaring 4 mm yang ditempatkan dalam KJA di laut (A), tambak (B) dan bak hatchery (C) sebagai perlakuan percobaan. Penelitian menggunakan rancangan acak lengkap dengan tiga perlakuan dan diulang 3 kali. Penelitian dilakukan selama 90 hari pemeliharaan, dan benih ikan kerapu sunu diberi pakan buatan komersial dengan kandungan protein 48%. Frekuensi pemberian pakan 2 kali sehari pada pagi dan sore hari.  Hasil penelitian menunjukkan bahwa pemeliharaan pada lingkungan berbeda tidak berpengaruh terhadap sintasan dan pertumbuhan mutlak panjang total namun berpengaruh terhadap pertumbuhan mutlak bobot benih (P<0,01). Pertumbuhan mutlak benih terbaik pada pemeliharaan di bak hatchery yakni 23,12±2,91 g, KJA 8,43±2,13 g dan tambak 12,58±2,58 g.  Kandungan protein benih ikan kerapu sunu tidak dipengaruhi oleh lingkungan pemeliharaan, namun kandungan kalori benih pada pemeliharaan di bak hatchery dan tambak lebih tinggi dibandingkan dengan yang di KJA.  Benih ikan kerapu sunu yang didederkan dalam bak hatchery memiliki pertumbuhan bobot mutlak 1,84 kali lebih tinggi dibandingkan dengan yang di tambak atau 2,74 kali dari yang  di KJA.

Abstract

Haematococcus merupakan alga yang kaya karotenoid dari jenis astaxanthin yang tidak hanya berpotensi sebagai sumber pigmen merah tetapi juga sebagai antioksidan. Aplikasi haematococcus telah dilakukan pada larva kerapu sunu dan menunjukkan adanya perbaikan peformansi warna merah yang cukup signifikan. Tujuan dari penelitian ini adalah mengetahui pengaruh haematococcus sebagai sumber astaxanthin terhadap pertumbuhan, total karotenoid, dan profil darah (hematokrit dan haemoglobin) pada juvenil ikan kerapu sunu. Benih kerapu sunu ukuran panjang rata-rata 14,07 ± 0,07 cm dan bobot rata-rata 45,92 ± 6,35 g dipelihara dalam jarring berukuran 0,5 m x 0,5 m x 1 m yang diletakkan dalam bak beton ukuran 3 m x 1,2 m x 1,2 m. Kepadatan ikan tiap jaring adalah lima ekor. Perlakuan yang diujicobakan adalah penambahan haematococcus ke dalam pakan buatan dengan dosis dan kompisisi sebagai berikut: A) 1% dari berat pakan, B) 1% dari berat pakan + 10% minyak ikan, dan C) 0% (kontrol). Hasil penelitian menunjukkan bahwa penambahan haematococcus ke dalam pakan tidak memberikan perbedaan nyata terhadap pertumbuhan mutlak panjang dan bobot, serta laju pertambahan panjang dan bobot (P value > 0,05). Penambahan haematococcus memberikan perbedaan nyata (P value < 0,05) terhadap konversi pakan di mana perlakuan A (1,99 ± 0,09); B (2,12 ± 0,14); dan C (2,28 ± 0,09). Penambahan haematococcus memberikan peningkatan terhadap akumulasi kandungan total karoten, hematocrit, dan haemoglobin darah.Haematococcus, an alga rich in carotenoids of the astaxanthin type, not only has the potential as a source of red pigment but also as an antioxidant. The purpose of this study was to determine the effects of hematococcus as astaxanthin source on the growth, total carotenoids, and blood profile (hematocrit and hemoglobin) of coral trout grouper juvenile. Coral trout grouper seed with an average length of 14.07± 0.07 cm and an average weight of 45.92 ± 6.35 g were maintained in a net cage measuring 0.5 m x 0.5 m x 1 m placed in a 3 m x 1.2 m x 1.2 m concrete tank. Fish density per net was five fish. The treatment tested was the addition of haematococcus into the artificial feed with the following dosages and compositions: A) 1% of the weight feed, B) 1% of the weight feed + 10% fish oil, C) 0% (control). The results showed that the addition of haematococcus to the feed did not give a significant difference to the absolute growth of length and weight and also specific growth and length rate (P-value > 0.05). The addition of haematococcus gave a significant difference (P-value < 0.05) to feed conversion ratio between treatment A, B and C with the values of 1.99 ± 0.09, 2.12 ± 0.14, and 2.28 ± 0.09, respectively. The addition of haematococcus also increased the levels of total carotene content, hematocrit, and hemoglobin. This study suggests that the application of haematococcus could significantly improve the red color performance of trout grouper larvae.

Abstract

A study on the effect of feeding frequency on coral trout culture Plectropomus leopardus was conducted in floating net cages. The aim of this study was to determine an optimum feeding frequency for better growth rate and feed conversion ratio. The experiment was divided into two stages, i.e.; using fish with a range of body weight of 24 to 100 g (1st stage), and fish with a range of 100 to150 g (2nd stage). The first stage, consisted of four treatments of feeding frequencies, i.e. four times a day (4/1), three times a day (3/1), twice a day (2/1), and once a day (1/1). For the second stage experiment, the treatments applied were, three times a day (3/1), twice a day (2/1), once a day (1/1), and once in two days (1/2). Each treatment was in triplicate. At each feeding time, experimental fish were fed with dry pellets to apparent satiation. Both first and second experimental stages showed that the treatments of twice a day (2/1) feeding frequency attained significantly higher growth rates and lower feed conversion ratios than other treatments (P<0.05). Survival rate at the first stage (4/1), three times a day (3/1), twice a day (2/1), higher than (1/1) (P<0.05). But in the second stage the survival rate is not significant. The most optimum feeding frequencies for this species is 2/1 for the fish of 24 to 150 g BW.

Abstract

Penelitian ini bertujuan untuk mengetahui waktu yang dibutuhkan untuk pengosongan lambung baik pada larva maupun benih ikan klon sebagai dasar manajemen pemberian pakan pada larva maupun benih ikan klon. Penelitian ini dilakukan pada larva umur 10 hari dengan panjang total 7,07±0,50 mm, dan benih umur 2 bulan dengan panjang total berkisar antara 2,64±0,23 cm. Masing-masing hewan uji tidak diberi pakan dari pukul 15.00 WITA (puasa selama 18 jam), kemudian keesokan harinya pukul 09.00 hewan uji diberi pakan buatan sampai kenyang untuk benih, sedangkan untuk larva diberi pakan Artemia selama 1 jam, setelah itu, air pada bak larva dialirkan agar pakan yang tersisa terbuang. Pengambilan sampel dilakukan setiap 1 jam pada larva sedangkan untuk benih dilakukan setiap 2 jam sekali. Hasil penelitian menunjukkan bahwa pada jam ke-4 isi lambung pada larva umur 10 hari sudah mulai kosong, sedangkan pada benih ikan klon isi lambung akan kosong setelah 11 jam 37 menit sejak pemberian pakan terakhir.
