Abstract
Rate of feeding was established at temperatures of 5[degree], 10[degree], 15[degree], 20[degree], 25[degree], and 30[degree]C. When either oyster spat (Crassostrea virginica) of 10-30 mm, or mussels (Mytilus edulus) of 20-30 mm, were used as food drills fed only intermitently at 10". The feeding rate increased with each rise in temperature from 10[degree] to 25[degree] then decreased at 30[degree]. Drills feeding on M. edulus ate less at all temperatures than those feeding on C. virginica. Drills kept at 5[degree] did not feed during 52 days'' observation; the minimum temperature at which any feeding occurred was 7.5[degree], although feeding was sporadic at this temperature. At 34[degree] drill mortalities were 70-80% after 16 hours.This publication has 1 reference indexed in Scilit:
