飼育下におけるスケトウダラ成魚の摂食量と成長
Food consumption rate and growth rate of the adult walleye pollock were measured at different temperatures (2-7, 4-10 and 9-15°C), body sizes (33-35, 35-39 and 39-45cm) and foods (juvenile walleye pollock, squid and sandlance). 1. The amount of daily intake indicated peaks at intervals of 5 days. 2....
