The effects of different illumination levels on zooplankton abundance and feeding periodicity, growth and survival of hatchery -produced Asian seabass, Lates calcarifer, fry in illuminated floating net cages were determined in a 35-day experiment. Zooplankton abundance (consisting mainly of copepods at 64-78% of total abundance in all cages) was highest in cages illuminated at 180 lx (mean: 124 individuals l-1) and at 300 lx (mean: 405 individuals l-1) and peaked at 0400. High prey densities subsequently resulted in increased fish feeding as evidenced by the greatest number of prey (mean: 416-462 individuals fish -1) found in their guts between 0400 and 0800. Feeding incidence (range: 84- 89% ) was generally higher among fish held in illuminated cages than those reared in dark cages (67%).
