MICROBE-LIFT Increases Sea Bass Hatchery Fry Survival Providing 100% Increase in Yield - Marine Life Aquaculture Farm, Singapore- Case Study
Background:
Marine Life Aquaculture Pte. Ltd. (MLA) is a high tech food fish hatchery located in Pasir Ris, Singapore. The company`s core business consists of the hatching and breeding of sea bass, thread fin, grouper, and other fish fry for commercial aquaculture farms in Singapore and surrounding countries.
Mr. Tan Kay Heok, the Chief Technical Officer of MLA has developed great expertise in the hatchery of commercial food fish. The farm has been using various innovative technologies to maintain food water quality in their hatchery tanks.
Objective:
Dr. Lim Lian Chuan, an expert in ornamental and food fish breeding and packing introduced MICROBE-LIFT® to MIA in December 2010 when they decided to test the technology in their sea bass tanks for potential improvement of yield and survival rate of fry. Three 20 M3 breeding tanks (tank 1, 2 & 3) were each stocked with 200,000 AVA sea bass eggs on 6 Dec 2010 after the tanks had been cleaned and sterilized with Remedor Aquatic (RA) and UV light which is their normal process to prepare the environment prior to stocking.
During the breeding period a rotifer and artemia diet was fed to the fry in all three tanks. Tanks 2 & 3 were maintained using the bath system that included daily exchange of 30% of the culture water, replacing backwater and seawater. Tank 1 was maintained by dosing with MICROBE-LIFT® . Because the trial tanks did not have biofilters or other filter media the dosage applied was higher than the standard recommendation by the manufacturer. Ecological Laboratories Inc. In addition, due to lack of filtration in any of these tanks, the fish manure and food waste were regularly siphoned off manually.
