Abstract

Giant gouramy Osphronemus gouramy Lac is one of the fish for food that has high economic value, but its production is not  met with the market demand yet.  The effort is needed to be done in order to increase production of giant gouramy fry by an intensive hatchery system through high rearing density.  This study was performed to determine the effect of rearing density on survival rate and growth of fry.  Fry were reared in aquaria 60x29x33 cm filled with 35 liters water, and fed by Tubifex at satiation as much as  0.23-0.28 g/fry/day with feeding frequency  2 times a day.   Collected  data were survival rate, growth, feed consumption, feed efficiency, and water quality.  The result of study showed that survival rate and feed efficiency did not affected by rearing density, while growth and feed quantity were did.  Survival rate of fish was high; 90.14-99.52%.  Growth and feed consumption were decreased by increasing of  rearing density.

ABSTRAK

Ikan gurame, Osphronemus gouramy Lac. merupakan salah satu jenis ikan konsumsi yang memiliki nilai ekonomi yang cukup tinggi, tetapi hasil produksinya masih belum dapat memenuhi permintaan pasar. Upaya perlu dilakukan untuk meningkatkan produksi benih ikan gurame dengan pembenihan secara intensif melalui peningkatan padat penebaran. Penelitian ini dilakukan untuk mengetahui pengaruh padat penebaran terhadap kelangsungan hidup dan pertumbuhan benih ikan gurami. Benih ikan gurami dipelihara pada akuarium berukuran 60×29×33 cm3 yang diisi air sebanyak 35 liter. Pakan berupa cacing sutera diberikan secara at satiation sebanyak 0,23 - 0,28 g/ekor/hari dengan frekuensi 2 kali/hari. Data yang diambil meliputi kelangsungan hidup, pertumbuhan, jumlah pakan yang dikonsumsi, efisiensi pakan dan kualitas air.  Hasil penelitian menunjukkan bahwa padat penebaran tidak mempengaruhi kelangsungan hidup dan efisiensi pakan, namun mempengaruhi pertumbuhan dan jumlah pakan yang dikonsumsi. Kelangsungan hidup selama pemeliharaan tergolong baik yaitu berkisar antara 90,14 - 99,52 %. Pertumbuhan dan jumlah pakan yang dikonsumsi ikan mengalami penurunan dengan meningkatnya padat penebaran.
