Synopsis (short abstract) The Malaysian Government has received technical assistance through the Besut Integrated Fisheries Development Project. The project had several components. The Tanjung Demong Hatchery and the development of aquaculture in the Besut Fisheries Development Area (FDA) were part of the project. The Tanjung Demong Hatchery conducted demonstration of freshwater prawn, Macrobrachium rosenbergii, fry propagation, the technique of tiger prawn, Penaeus monodon breeding, and the demonstration on nursing seab ass, Lates calcarifer from one day old fry to 1.5–2 cm fingerlings. The development of aquaculture included the demonstration on the technique of seabass culture in ponds at Fikri, from 8 to 10 cm fingerlingers to marketable fish of 600–700 g, which takes about six months. Demonstration on techniques of seabass and greasy grouper Epinephelus tauvina culture in floating net cages at Setiu Lagoon and Kuala Bharu were also conducted. The fingerlings from 8 to 10 cm took about 7–8 months to raise to marketable size. This year stocking of fingerlings started in February at Setiu Lagoon, in March at Kuala Bharu and in April at the Fikri ponds. This fish both in cages and ponds should reach marketable size in September. On 15 June the seabass ranged from 40 to 160 g and greasy grouper from 60 to 105 g. Trials on tiger prawn fry culture in plastic net cages were also conducted. Average stocking size was 0.463 g in weight and 3.53 cm in length. Within 18 days the average weight was 1.356 g with an average length of 4.76 cm; the average weight gain was 0.893 g. It means that the weight gain was more than double from the date of stocking. Mortality was only 1.2%.
