Abstract

The natural stock of sea cucumber Holothuria scabra (known as sandfish) has been declining in both population and size, making it difficult to collect broodstock and juvenile sandfishes for aquaculture. This research aims to evaluate the reproduction of domesticated broodstock (F-1) and performance of the juveniles (F-2). Broodstock were reared in two rectangular concrete tanks with a dimension of 190 x 290 x 70 cm3. There were 12 individuals (7 males and 5 females) of broodstock (F-1) with total length and mean body weight of 12.0 ± 1.21 cm and 122.6 ± 32.37 g, respectively. Six broodstock were put in each tank and fed with compressed benthos at 4% biomass daily in the afternoon. During our experiment, domesticated sandfish broodstock successfully spawned twice. The first spawning (occurred in January 2017) had one female spawned that released 1,350,000 eggs with a hatching rate of 57.4%. Another broodstock spawned in April 2017 and produced 3,280,000 eggs with a hatching rate of 78.66%. The growth performance of 170 days-old juveniles (F-2) shows a total length of 5.66 ± 0.90 cm and a mean body weight of 10.08 ± 2.07 g. The survival rates are 5.19% and 8.68% for juveniles spawned in January and April, respectively. We conclude by showing that sandfish could be domesticated to produce seeds for further aquaculture development.

Abstract

Bandeng merupakan ikan yang memiliki rasa daging yang enak, harga relatif terjangkau oleh segala lapisan masyarakat dapat dibudidayakan secara polikultur dengan komoditas lainnya dan banyak petani yang melakukan usaha budidaya. Kendala di masyarakat bahwa pertumbuhan benih bandeng yang dihasilkan oleh pembenih memiliki variasi ukuran yang tinggi, dan pertumbuhan yang lambat di tambak. Tujuan dari penelitian adalah untuk mengetahui teknologi budidaya ikan bandeng, dan memperoleh data biologi induk bandeng G-1. Hewan uji yang digunakan adalah induk bandeng G-1. Penelitian dilakukan secara deskriptif, yaitu melakukan pengamatan secara fenotipik meliputi pertumbuhan setiap dua bulan sekali. Parameter yang diamati adalah beberapa aspek biologi bandeng hasil seleksi antara lain kualitas telur, sintasan, pertumbuhan, pengujian warna, kualitas daging, toleransi terhadap lingkungan, dan ketahanan terhadap penyakit. Hasil penelitian menunjukkan bahwa daya tetas telur berkisar 80-90,30%, dan memiliki ketahanan larva (SAI) mencapai 4,0-4,6 hari setelah menetas. Kelangsungan hidup dan pertumbuhan benih G-2 pada pembenihan umur 14-16  hari (SR) mencapai 60-85%, panjang total (TL) 1,68-1,72 cm, Warna induk bandeng dan ukuran konsumsi dengan menggunakan adalah hijau pada nomor TC.4408 dan perak TC.5501. Kualitas daging dari bandeng G-1 memiliki nilai 8. Kadar histamin untuk semua lokasi budidaya ND (non-detections). Toleransi benih terhadap lingkungan, ikan bandeng memiliki ketahanan terhadap salinitas 0-45 ppt, suhu 20-40°C, pH 6-9, dan oksigen lebih dari 2 ppm, kemudian memiliki ketahanan terhadap penyakit.

Abstract

Silver pompano fish is a prospective commodity that can be cultured and contains high economic value. Due to its high economic value nationally and internationally, it is important to develop nursery business. The silver pompano fish nursery conducted in a pond become efficient because it can be easily controlled. The purpose of the study was to know the technology and growth of silver pompano fish fry in cages at a pond. Research activities were carried out in the hafa size (3x3x1m3) in ponds. The seeds were taken  from hatchery with size of 5.0-6.0  cm. Stocking density of seeds  were 50 pc/ m³. The nursery were reared  for 90 days till the fry reached their size in between   15.0 and 18.0 cm. The commercial  pellets with protein content of 28-30% with dose of 5-8% of body weight were provided in the morning and afternoon at satiation. Sampling of fry was conducted every 30 days, to measure the survival rate (SR), total length (TL) and body weight (BW). Data were processed with descriptive analysis. The results showed that the survival rate was 90.20 ± 2.60 %, total length was  16.80± 2.70 cm, and body weight was  145.20 ± 2.70 g. The diversity of fry has four size categories i.e., large (L), medium (M), small (S), and super small (SS) with percentage average of 17.50%, 52.70%, 20.70% and 9.10%, respectively. Keywords: net cage, pond, silver pompano fish, growth, survival
