Fish Population Dynamics and Stock Assessment. Red Sea, Egypt

Epinephelinae, represent one of the most important families in the Egyptian sector of the Red Sea Epinepheline or grouper are abundant, valuable and economical fish food. The present work has been suggested due to the rarity of biological, population dynamics, stock assessment and fisheries studies with respect to three Epinepheline species, Cephalopholis argus, Cephalopholis miniata and Variola louti from the Red Sea at Al- Quseir south of Hurghada by 140 Km, Egypt. The present work is a part of a project executed in Assiut University to study the biology and fisheries of the Red Sea fishes, so more advanced techniques and statistical methods were considered to answer a lot of important questions. The results of the present work can be summarized in the following points: 1. Identification of the stocks of C. argus, C. miniata and V. louti by: A) Scale characteristics. B) Morphometrics and meristics. 2. Growth in Weight of the three Epinepheline species. 3. Determination of the pattern of population dynamics and stock assessments of the three Epinepheline species considered. 4. Comparing the stock characteristics of the three Epinepheline species
