Feeding habits and the influence of pellet diameter on the feeding responses of the flathead grey mullet (Mugil cephalus) in captivity

The feeding habits and effect of the diameter pelleted feeds on responses wild juvenile adult flathead grey mullet (Mugil cephalus) in captivity were examined. Optimal pellet size for was defined according to behavioural ingestion pellets with different diameters (2, 4, 6, 8 mm) that dropped into tank a random sequence. Larger (6 more attractive (lower reaction time, high percentage capture), but small medium-sized (2 4 consumed most. optimal 2- 4-mm individuals (365.50 ± 36.90 g; 28.8 0.84 cm) adults (937.49 146.54 40 1.12 cm). preferred area also studied estimate preference relation characteristics such as floating or sink. Two types, sinking, offered simultaneously water column: at surface, mid-water column bottom tank. had feed tanks indicating sinking slow-sinking would be type behaviour.
