Species Composition, Distribution and Morphometric Parameters of four Penaeid Shrimp Species from Lake Burullus
The species composition, abundance, and morphometric relationships of Penaeid shrimp species were subjected to study using monthly samples collected from Burullus Lake. In the lake catches, four species were recorded; namely, Penaeussemisulcatus, Metapenaeus stebbingi, Metapenaeusmonoceros and MarsupenaeusJaponicus. The overall composition of shrimp by number showed that M.monoceros was the most abundant constituting more than 30% of the catch of shrimp, followed by P.semisulcatus (27.3%) and M. stebbingi (23.3%). While, M.Japonicus was recorded as the least abundant species, with a percentage of 18.6. The shrimp overall composition by weight revealed that P.semisulcatus was the most represented shrimp species in the catch (47%) followed by M.monoceros (24%) and the other two species M.Japonicus (16 %) and M. stebbingi (13%), showing the least abundant existence in the catchweight. The results showed that autumn months are the most shrimp productive months, while winter and early spring are the least productive months. The occurrence and distribution of shrimp in the lake are influenced by salinity and the geographical distribution is restricted on the northern part of the lake in the areas close to Boughas Al-Burullus. The morphometric relationships were investigated for each sex separately by fitting regressions to total length on total weight, carapace length on total weight and total length on carapace length for the four studied species. The correlations were all statistically significant (Ps<0.001). The results showed that females of these species reach larger sizes and gain more weight than males. These results may help in the maintenance of these valuable stocks in the lake.
