| Abstract | ||||
| The length-weight relationship and growth performance of Sparus aurata and Dicentrarchus labrax were calculated at the El Mokretar Aqua fish farm in the Bay of Souahlia on the Algerian coast. During harvest, fish samples were collected from the El Mokretar Aqua fish farm in floating cages C8 and C3. Growth parameters were assessed at the start and end of breeding. The simple fisheries stock Aassessment methods (FSA) package estimated the length-weight relationship as LogWt= -1.18+2.08logLt for D.labrax and Log Wt= -6.17+3.62logLt for S. aurata. These relationships indicate that the European seabass has a negative allometric growth, while the gilthead seabream has a positive allometric growth. During the rearing period, the zootechnical performance of the gilthead seabream and European seabass indicated favorable growth. Weight gain, specific growth rate, Fulton's condition factor, thermal-unit growth coefficient and feed conversion ratio showed a significant difference. These indicators are useful for planning and managing fish farms rearing these selected species. | ||||
