dc.description.abstractFeeding, respiration and growth rates of oyster (Ostrea edulis L.) larvae reared at five food levels were measured throughout the entire larval period. Energy budgets were derived as a function of alga (Isochrysis galbana Parke) food concentration. Ingestion rate (IR, cells h-1) and oxygen consumption rate ( VO2 , nl h-1) were almost isometric functions of larval size [ash-free dry weight, (AFDW, μg)], characterized by the equations: IR=803.9 AFDW1.13 and VO2 =4.85 AFDW1.09. Ingested ration was directly correlated to cell concentration up to a maximum at 200 cells μl-1, with further increases failing to support higher ingestion rates. Likewise, growth rate linearly increased with food ration up to 100 cells μl-1 (max. growth efficiency,K 1=25%) and reached a maximum at 200 cells μl-1 (growth rate=5.6 μm d-1), with further increases in food not supporting significantly faster growth. Maintenance ration was 2 to 3% daily dry weight (DW); optimum ration increased during larval development from 5 to 20% DW; maximum ration was 20% DW. During larval rearing, an increasing feeding schedule of 50, 100 and 200 cells μl-1 from Days 0, 5 and 10, respectively, is recommended.en_US
