Outline of Final Research Achievements

For improving feeding amount of cultured yellowtail, feeding stimulants and pro-digestive substances were investigated. Neuropeptide Y (npy) and cholecystokinin (cck) were used as indicator for the appetite and digestion in this study. Hypothalamus npy responded to inosine-monophosphate and alanine dissolved in the rearing water. Cck responded to Trp、Gln、Phe、Pro、Ala、Leu、Met in the organ culture of pyloric caeca. Improvement of feeding amount was suggested by dietary supplementation of those substances.

Academic Significance and Societal Importance of the Research Achievements

魚類養殖では,資源量が枯渇しつつある天然魚を魚粉として飼料に用いている。持続的な魚類養殖のためには,魚粉含量を減らした飼料(低魚粉飼料)の開発が進められている。しかしながら,飼料を低魚粉化すると摂餌量が減少し,それに伴って成長の低下が起きる。低魚粉飼料における摂餌量減少の理由として,摂餌刺激物質の不足による【食欲の低下】と消化促進物質の不足による【消化の遅延】が考えられる。本研究は、低魚粉飼料の摂餌量を増加させるために【食欲】と【消化】の栄養素による調節機構を内分泌学的に解明した点に学術的意義があり、またその成果は将来、魚類養殖に応用可能であることからも十分な社会的意義がある。
