| The present study deals with the fisheries of two Sparid fish species in Abu Qir Bay. Family Sparidae represents about 17 % of the landed catch from the Bay. Among the family; genus Diplodus is generally caught by trammel nets, beach and purse seines but mostly by longlines. Two species of this genus were considered here for study. They are namely D. sargus and D. vulgaris where they represent by about 4.2% of the landed catch during the year 2008 in the Bay (GAFRD, 2008). The length weight relationship of both species under study showed a value of exponent “b” of very slight negative allometry. Analysis of the catch length structure of the two species revealed that the catch of D. sargus is composed of 21 length groups, the least length was 7.5 cm and the... |
