Growth of Fry Fish of 4 Species of Family Mugilidae in Experimental Recirculation Water System

Abstract

The collected in nature fry of Mugil cephalus, Liza aurata, L. ramada and Chelon labrosus that arrive in massive schools at the coastline of Greece were reared in small aquaria (50 L) of a recirculation system from the size of about 3.0 cm TL (50 fish per aquarium), using brackish (15 ppt) water and artificial high protein food. It was found that for a period of 80 days, growth performance was high at 23 oC, reaching values for weight increase between 592 (M. cephalus) and 2281 % (L. aurata). Food Conversion Ratio (FCR) was best (1.04) for L. aurata and worst (2.04) for M. cephalus. All species responded well as exhibited by an increase in their Condition Factor (CF) and mortality was almost absent.
