FEEDING SELECTIVITY OF ARTIFICIALLY REARED BLACK PORGY LARVAE, SPARUS MACROCEPHALUS (BASILEWSKY)
Abstract:
In rearing marine fish larvae, first feeding is important for the survival rate. In this experiment, black porgy larvae were fed on oyster trochore larvae, rotifers and artemia nauplii. Analysis of the food in the fry intestine showed that 3 to 6 days old black porgy fed mainly on oyster trochore larvae, 7 to 19 days old fed mainly on rotifers and 20-day old and onwards mainly on artemia nauplii. Of the three kinds of live food, the most suitable one for the first feeding black porgy larvae is the oyster trochophore larvae.
