Abstract

Currently, there is a national concern regarding to the decrease of milkfish production from ponds in North Java due to a low quality of milkfish seed produced by small scale hatcheries in Bali, which is the main producer of milkfish seed. The quality of seed is strongly related to the quality of eggs (fertility), while quality of eggs produced depends on the management of brood stocks carried out by the hatcheries. Growth rate and growth hormone profiles are some of the biological aspects that could be used as a basis/benchmark to evaluate quality level of milkfish seed reared in ponds. The aim of this experiment was to evaluate growth rate and growth hormone profile performance between selected G-2 seed and small scale hatcheries seed as control population the growth rate. Research on grow-out of milkfish seed was conducted at the IMRAD ponds facility in Pejarakan, using milkfish seed produced by small scale hatcheries as well as selected second-generation (G-2) seed, each with the density of 5000 seed/pond (1 pond=0.5 ha). The seeds were fed with dry pellet and reared for 5 – 6 months. The results showed that the seed produced with standard operational procedure (SOP) by small scale hatcheries were having longer (F hit. = 13.68 > F tabel 1%) and heavier body washt (F hit. = 18.98 > F tabel 1%) better than selected G-2 seed and small scale hatcheries seed without SOP with high growth hormone concentration (F hit. = 4.95 > F tabel 5%).

Abstract

Survival rate of coral trout seed produced from aquaculture was relatively low. In 2015, high mortality was found at the early stage of larval development (<D10), approximately 64.37 % of the total production. There has been no standard management for coral trout (Plectropomus leopardus) larval rearing, which was used to adopt management for grouper (Epinephelus spp.) larval rearing. This study was to apply suitable management for coral trout larval rearing into aimed to decrase mortality at early stage larval development and to increase survival rate. There were two different managements in this study: A. applying the results of previous research of coral trout larval rearing from 2004 to 2015, and B. using standard management for grouper larval rearing. The results showed that management A was more suitable management for coral trout larval rearing compared to management B. Management A resulted in the increasing of survival rate by five times (p=0.0056) and of growth rate at early stage by 1.15 times (p=0.2338) higher than those of management B.
