Some Fishery Aspects on the Brushtooth Lizardfish Saurida undosquamis (Richardson, 1848), Inhabiting Two Different Egyptian Water Environments
The fishery aspects of the lizardfish Saurida undosquamis were studied in the northern Gulf of Suez and the southeastern Mediterranean. Samples were monthly collected from March 2018 to February 2019. A sum of 1110 samples were obtained from both sites. The length-weight relationships for the whole population were W= 0.0045L3.10 and W= 0.0032L3.23, respectively, while the life span was six years for the Gulf of Suez population and five years for the Mediterranean Sea one. The theoretical length (L∞) was 45.49cm (about 1.49ft) for the Gulf of Suez population and 42.88cm (about 1.41ft) for that of the Mediterranean Sea. The growth performance indices (Φ) were 2.488 and 2.397 for the studied sites, respectively. The demographic structure for both populations was estimated. The mortality coefficients (Z, F, and M) were calculated in addition to the exploitation rate (E). Our results suggest that the Gulf of Suez population is exploited higher than that of the Mediterranean Sea.
