THE QUATERNARY SEDIMENTS OUTCROPPING ALONG EGYPTIAN COAST OF THE RED SEA AREA ARE REPRESENTED BY A SERIES OF TERRACES INCLUDING A SEQUENCE OF MIXED SILICICLASTICS, REEFAL CARBONATES AND EVAPORITES. IN ADDITION TO SEA LEVEL CHANGES AND CLIMATIC CONDITIONS, TWO MAIN FACTORS CAUSED THE RAPID FACIES VARIATIONS OF THESE SEDIMENTS. THESE ARE THE EASTERLY TRENDING TECTONICALLY-CONTROLLED WADIS AND FRACTURES AND THE ... Read more

Some biological aspects and population dynamics of the five-lined snapper, Lutjanus quinquelineatus (Family: Lutjanidae) from Red Sea off Hurghada, Egypt
Age and growth, reproductive strategy, mortality and yield per recruit analysis are essential to evaluate the fishery status of fish stocks. The fishery status of five-lined snapper Lutjanus quinquelineatus in Hurghada fishing area was assessed based on the monthly representative samples covered 12 months from January to December 2016. The von Bertalanffy equation for the growth in length was: Lt ... Read more
