抄録

The effects of partial replacement of dietary protein by fish oil and palm oil on growth and hepatopancreatic enzyme activities were investigated in red sea bream Pagrus major. Fingerlings of 11.4 g average body weight were fed for 12 weeks on 4 experimental diets containing different fat (20 and 24%) and protein (43 and 37%) levels, and on a low fat (15%) high protein (52%) control diet. The highest weight gain, specific growth rate and feed efficiency were noted in the control diet group. Hepatopancreatic isocitrate dehydrogenase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, aspartate aminotransferase and alanine aminotransferase activities decreased in all fat rich diet groups compared to the control diet group. These activities of the palm oil rich diet groups were lower than those of the fish oil rich diet groups. Glucose-6-phosphatase and fructose-1, 6-bisphosphatase activities in fish fed the palm oil rich diets were lower than those in fish fed the control diet, while they were minimally affected by the dietary fish oil level. These results indicate that fingerling red sea bream cannot utilize a high fat low protein diet well and palm oil depresses more severely hepatopancreatic lipogenesis, amino acid degradation and gluconeogenesis than fish oil.
