Abstract

Bardawil lagoon is one of the most important fishing grounds in Egypt, since it is the least polluted lagoon in Egypt and in the whole Mediterranean as well as the majority of fish species are exported. Analysis of fish yields and efforts performed in Bardawil lagoon during the period 2003-2012 was done. Production trends of yearly total fish yields revealed an increasing trend with decreasing increments (R2=71.9, P=0.018). The same trends were observed for both crabs (R2 = 76.9, P=0.003), shrimps (R2= 58.9, P=0.04) and sea bream (R2=57.7, P=0.05), while that of family
Mugilidae revealed increasing trends along the period of study (R2=28.0) with insignificant relationship.
Analysis of efforts exerted by shrimp trawl net revealed that the number of hauls seems to be the controlling factor as stepwise regression between the different catches resulting from the shrimp bottom trawl net and the number of hauls had shown significant relationships except large shrimps which showed insignificant relationship.
Banning of fishing by shrimp trawl net should be superior more than further studies to develop such fishing method, as there is an alternative eco-friendly shrimp fixed traps which should be used. In addition to its destruction effect to the bottom habitats and bottom flora which acts as shelter and spawning areas for many fish species.
