| Abstract | ||||
| The data of the present study on fisheries of the Bardawil Lagoon cover a successive 29 years from 1968 to 1996. Two main fishing techniques are used at present; Bouss and Dabba. The surplus production model of Fox (1970) was appl ied for measur ing the maximum sustainable yield (MSY) and the corresponding exerted effort; fmax. The results were MSY = 2251.907 tons and fmax = 653.268 Dabba units. For management according to f0.1 level; the maximum economic yield (MEY) attains 2190.122 tons and fMEY 511 Dabba units. It is clear that, at f0.1 level the MEY value realizes about 97 % of MSY value and reducing 61.687 tons or 2.74 % of yield, while the reduction of fishing effort reaches about 22 % at f0.1 level. | ||||
