Characterization of the reproductive biology of the Sparid fish: Rhabdosargus haffara in Suez Bay, Red Sea

Fisheries biology of the haffara bream Rhabdosaragus haffara (Family: Sparidae) in Suez Bay, Egypt.

“…The condition factor is studied to assess the wellbeing state of fish during its life span (Osman, 2016). This study revealed that R. haffara is in wellbeing state during spring after spawning and it is more exhausted during winter, as Osman et al, (2020) reported that the peak of the spawning season for R. haffara in Suez bay is during winter, this implies that R. haffara is more exhausted during its spawning season.…”

“…Length at first capture for R. haffara population the Suez bay is 13 cm, According to Osman et al, (2020), Length at first maturity (L m ) for R. haffara in the Suez bay was estimated to be 12.7cm. For proper fisheries management L c should be more than L m by at least 2.0cm.…”

“…It is a carnivorous fish feeds on benthic invertebrate (Sommer et al, 1996). Family Sparidae is represented in small scale fishery (trammel and gill nets) operating in the gulf of Suez and Suez bay by seven species, the most dominant one of them is R. haffara (Osman et al, 2020). R. haffara is Lessepsian migrant species from the Red Sea to the Mediterranean Sea through Suez Canal (Golani, 1998).…”

Reproductive biology of the two commercially important grouper species Epinephelus summana and E. polyphekadion in the Egyptian coast of the Red Sea

“…Reproduction is one of the most important biological characters which should be studied for fisheries management (El Ganainy, 2004;Osman, et al, 2020). It gives the predictable future for fish production and new recruit adding for the recent stock.…”

“…Then samples were dissected for sex determination. Maturity stages were recorded and gonads were weighed to the nearest 0.01 g. All ovaries and testes were assigned a macroscopic stage based on El Ganainy (1992) and Osman et al, (2020) where, Ⅰ undifferentiated gonad (threadlike), II immature, III developing, IV ripe, V spawning (running) and VI spent.…”
