GROWTH AND PHYSIOLOGICAL PERFORMANCE OF SEA BASS FRY AND FINGERLINGS UNDER DIFFERENT SALINITIES

Abstract

The present experimental work has been carried out in three locations according to the stages of the experiments: - • The first experiment pre-fattening stage in K21 Marine hatchery belongs to General Authority for Fish Resources Development (GAFRD) Alexandria, Egypt. • The second experiment fattening stage to the table market size in Fresh Water System at Al-Keram Intensive Farm (private Sector) Albehera, Egypt. • The second experiment fattening stage to the table market size in Brackish Water System at Al-Manzala Intensive farm belongs to General Authority for Fish Resources Development (GAFRD) Al-Manzala, Egypt. The objective of this study is to contribute the food security from high value fish protein sources, investigate through of the effect use of different salinities in fish growth performance, fish feed requirements and physiological nature of marine fish, European Sea Bass (Dicentrarchus labrax L., 1758) as a high value fish species for aquaculture investment opportunities.
