Comparation of Diets Used for Larviculture of Meagre (Argyrosomus regius Asso1801)
Journal Title: Journal of Experimental Agriculture International - Year 2016, Vol 11, Issue 6
Abstract
This investigation compared the suitability of different diets for larviculture of meagre (Argyrosomus regius). For this purpose, wild fish were caught with longline and subsequently fed either a commercial diet or a mollusc diet. After two years, there was a significant difference between the two diets in the body weight but not the survival rate of the fish (P<0.05). Both the weight gain and the FCR were significantly higher in fish that were fed the commercial diet compared with those fed the mollusc diet. Three alga diets were used for the initial feeding of larvae: A1, A2 and A3, consisting of 30/70, 60/40 and 50/50 Nannochloropsis sp./Isochrysis sp., respectively. There was a significant difference in larval survival rate among the alga diets (P<0.05). These results indicate that meagre readily tolerates commercial production systems, where it can grow rapidly and easily reproduce.
