The Tiger Grouper Hatchery Techniques In The Lampung Marine Aquaculture Centre, Indonesia

Abstract

The tiger grouper (Epinephelus fuscoguttatus) exhibits characteristics ideal for cultivation due to its rapid growth rate and ability to be mass produced to satisfy market demand. The aim of this study is to implement the Tiger Grouper Hatchery Technique and measure the Fecundity, Fertilization Rate (FR), Hatching Rate (HR), and Survival Rate (SR) at the Tiger Grouper (Epinephelus fuscoguttatus) Hatchery located at Balai Besar Lampung Mariculture Fisheries. The chosen survey method allows for the collection of relevant data for the aforementioned parameters. Data can be collected through primary and secondary sources, as well as observation, literature review, and documentation. Hatchery techniques for Epinephelus fuscoguttatus, include the selection of parent fish, brood rearing, spawning, egg handling, larval rearing, harvesting, maintenance and transportation of seeds. The quantity of eggs laid was 3,292,475, with an average fertilization rate of 88.76%, an average hatching rate of 22.57%, and 350,000 larvae stocked, leading to 21,000 individuals or 6% survival ratio, measuring 1-3 cm in size.
