The present study presents biological aspects of golden grey mullet, Liza aurata (risso, 1810) from Bardawil lagoon, Egypt. A total 1329 specimen's individuals were collected different landing sites Lagoon in the period May 2017 to February 2018. Length-weight relationship, condition factor, age composition, and fish growth studied. length weight ranged 12.2 33.6 (cm) 13.8 340 (g) respectively....

The reproductive biology of Mugil liza Valenciennes, 1836 is described as a contribution to an elaborate management programm. A total of 243 specimens (89 males and 154 females) were collected in the Sepetiba Bay in south-eastern Brazil from July/2006 to June/2007. The gonadosomatic index (IG) and the sequential development of the ovaries observed through histological studies suggested that the...

Dispersant use in nearshore areas is likely to increase the exposure of aquatic organisms to petroleum. To measure the toxicity of this controversial response technique, golden grey mullets (Liza aurata) were exposed to mechanically dispersed oil, chemically dispersed oil, dispersant alone in seawater, water-soluble fraction of oil and to seawater as a control treatment. Several biomarkers were...

Background: The concentrations of heavy metals in the tissues and organs of fishes indicate the concentrations of heavy metals in water and their accumulation in food chains. In the present study, the concentrations of Zn, Cu, Cd, Ni, V and Pb in three common species of fish and the potential health risks to local residents via consumption of the fishes were estimated.  Methods: The con...

Among of the actual challenges for sustainable aquaculture development are to lower trophic level cultured species, and increase use by-products from primary sector. The golden mullet (Liza aurata) is a marine low consumer present in Mediterranean Canary Islands, where there was significant consumption past. On other hand, Aloe vera plant, which production Islands highly world representative, c...

An acute mortality caused by an uncertain agent occurred in wild golden grey mullet (Liza auratus) population in the Iranian side of the Caspian Sea in February, 2004. Clinical signs of the moribund fish were erratic behavior such as spiral swimming, belly-up at rest and over inflation of swim bladder. Histological examination of brain of dead fish revealed hyperaemia, degeneration and necrosis...
