چکیده

On the 15 days after hatching, the larvae was 4.24-5.10 mm (mean 4.66±2.18 mm) in total length, and the fins of the membrane started to develop into a fan shape and the melanophore was deposited upper the alimentary canal of the abdomen and on the bladder. At 35 days after hatching, the post-larvae formed a branch-shaped melanophore on the head part with a total length of 6.98-12.5 (mean 9.35±1.71) mm, formed on the upper and lower parts of the caudal part, formed on the upper and lower parts of the caudal part, and deposited under the head part and abdomen. At 40 days after hatching, the juvenile was 11.3-18.1 (mean 14.9±1.53) mm in total length.

Effects of 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD) on the Peripheral Nervous System in Developing Red Seabream (Pagrus major) Embryos

Bony fish is highly sensitive to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure, especially at early developmental stages. TCDD induces various toxic effects including yolk sac edema, craniofacial malformation and neural damage in developing fish embryos. However, the effects of TCDD on the peripheral nervous system (PNS) of fish remain unclear. To clarify whether TCDD affects the morpholo...

The first report of two monogenean gill parasites assigned to Diclidophora merlangi (Diclidophoridae) and Loxuroides pricei ‎‎(Axinidae) from brushtooth lizardfish and red porgy seabream of ‎the Red Sea, Egypt

Monogenea is one of the most species-rich groups of parasitic flatworms worldwide with many species described from African freshwater fish. Little is known about the diversity and geographic distribution of monogenean parasites infesting the Red Sea fishes in Egypt. In the present study, a total of 45 specimens of the brushtooth lizardfish Saurida undosquamis (family: Synodontidae) and...

The effect of food deprivation on the fatty acid and lipid profile of red seabream (Pagrus major) larvae.

Under conditions of food deprivation the lipid fraction of red seabream (Pagrus major) larvae shows patterns of conservation or loss in the profile of fatty acids and lipids. These changes were used for qualitative formulation of the dietary requirements of this species. Red seabream larvae were deprived of food for 5 d after hatching. Their lipid was extracted, weighed and analysed by gas-liqu...

Morphological, Histological, Histochemical and Behavioral Aspects during Early Development of Red Porgy Pagrus pagrus L. Reared in Mesocosm

The present study provides a description of the morphological, histological and histochemical development, and the ecological implications of red porgy larvae reared in mesocosm, from hatching to 30 days after hatching (DAH). Four development stages were defined by body total length (TL), in agreement with major patterns of larval organogenesis. The first stage was characterized by the highest ...

Extra- and intra-cellular ice formation of red seabream (Pagrus major) embryos at different cooling rates.

The ice crystal formation is assumed as the most lethal factor for the failure of fish embryo cryopreservation and intracellular ice formation (IIF) plays a central role in cell injury during cooling. The objectives were to observe the morphological changes of red seabream (Pagrus major) embryo during the cooling-thawing process, and to examine the effect of cryoprotectant and cooling rate on t...
