Light intensity requirements for feeding behaviour by the brown-marbled grouper, epinephelus fuscoguttatus

In this study, we investigated the feeding behavior of the brown-marbled grouper, Epinephelus fuscoguttatus with light intensities ranging over eight orders of magnitude from 0–1000 lx to estimate the optimum light intensity for larval rearing. Artemia ingestion rates of E. fuscoguttatus of 36 days...
