METHODOLOGY IN THE STUDY OF SEA-BASS (LATES-CALCARIFER BLOCH) - NUTRITIONAL-REQUIREMENTS IN SINGAPORE

This paper describes the effort of the Marine Aquaculture Section of t he primary production Department in Singapore and the Institut Francai s de Recherche pour l'Exploitation de la Mer in developing adequate fa cilities for fish nutritional requirement studies in Singapore, and in introducing appropriate nutritional methodology so that results are r eliable and accurate. One of the first achievements was the demonstrat ion of homogeneous fish (tropical seabass, Lates calcarifer Bloch) gro wth response in a newly established rank system before any nutritional experiments were initiated. The application of statistical procedures that take into consideration the power of a test and number of requir ed has allowed for more accurate interpretation of results. This can b e seen in the results of the first nutritional requirement experiment on the optimal dietary protein level of the seabass at constant energy .
