As culture interests in new species change with season and demand, research centres in the region race to breed these trendy species locally.

It has been the trend with marine fish farmers to change species with season, prices and availability of fingerlings. Breeding and larval rearing technology had to keep up with these fast changing demands. We also had to keep up with progress in the hatcheries and research institutes in Taiwan and Indonesia, leaders in marine fish fry production. Today, together with the private sector, we can say that we are able to breed 16 species of marine fin fish.

The centre was initially established as a production centre for marine fish and shrimp fry production.

Breeding the tiger and giant grouper Currently, breeding technology is centred on the popular tiger grouper and MAFPREC holds the brood stock in cement tanks.

Three pairs are used for spawning via hormonal stimulation each month to produce 5 to 10 million eggs per spawning. Brood stock is keraup every years with wild stocks.

Eggs are supplied free to private hatcheries such as former marine shrimp hatcheries for larval rearing and nursery to 2. The hatcheries kerpu these at MYR 1 per 2.

The giant grouper is the next popular species. The centre holds 95 broodstock of which only are ready to spawn.

Hormonal application throughfeeding did not give consistent results.

The centre is looking at novel application techniques in hormonal sex reversal to have more malesto work with.
