ABSTRACT
Catch per effort statistical analysts has been
adopted on Egyptian northern Delta Lakes in order
to study the relation between the catch of unit
effort (CPUE). effort and the corresponding
conmercia1 catch ff’Olll each lake during 196Z – 1983
period.
Fish catch from each lake has been found to
be positively correlated with the catch per unit
effort (fisherraan, boat). On the contrary, nulllbers
of fishermen and fishing boats at any of these
lake were not significantly correlated with the
annual conmercial catch. Fish catch was determined
in the northern lakes by fish density and not by
fishing effort.
