Última Age precision and growth rate of Rhabdosargus haffara (Forsskål, 1775) from Hurghada fishing area, Red Sea, Egypt ArchiMer Osman, Yassein A. A.; Mehanna, Sahar F; El-mahdy, Samia M; Mohammad, Ashraf S; Mahe, Kelig. The age and growth of the haffara seabream, Rhabdosargus haffara (Forsskål, 1775) from Hurghada fishing area, Red sea, Egypt, were investigated using a sample of 466 specimens. The fish length varied between 12.7 and 27.2 cm and the weight from 38.1 to 293.2 g. Samples were collected from the artisanal fisheries during the fishing season from August 2018 to July 2019. The relationship between the body lengths (total, fork and standard length in cm) and the body weight (g) was found to be significant (p < 0.05). The relationship between the body length and weight regarding the sex effect was insignificant for all samples (log W- log TL, ANCOVA, p > 0.05). The relationship between length and weight was estimated by a power regression function, with a...

Ano: 2020 URL: https://archimer.ifremer.fr/doc/00623/73484/72774.pdf Recovery probabilities of coral reef communities after Acanthaster planci infestation: a case study at Shabror umm gam'ar, Hurghada, Red Sea, Egypt OceanDocs Ammar, M.S.A.. Recovery patterns of coral reef benthic communities were estimated by linear extrapolation after Acanthaster planci outbreak of 1998 at Shabror Umm Gam'ar, Hurghada of the Egyptian Red Sea. The significance of using linear extrapolation was tested in a range of ten sites by comparison with the actual average yearly recovery rates. A total of 15 permanent transects, each is 10m long, were monitored at 10m and 12m depths in both Shabror Umm Gam’ar and the ten selected sites. The recovery rate estimated by linear extrapolation did not significantly differ from the recovery rate of stony corals in the ten selected sites. Moreover, an error of +7.69% to +17.5% increase in the extrapolated recovery rate exists and should be considered while handling the...
