The paper focuses on some of the biological characteristics of golden grey mullet, Liza aurata in Iranian waters of the Caspian Sea. Samples of commercial catch of mullet obtained by means of beach seine fishing cooperatives along the Iranian coasts of Caspian Sea (2007-2008) as monthly interval. Samples subjected to biometric measurement to specify their biological characteristics. The male/f...

The grey mullet fingerling were imported to Iran in 1997 from Hong Kong and in coastal fish pond of north part of Iran were successfully cultured in order to obtain broodstocks and induce artificial reproduction. Seasonal changes in serum concentrations of Testosterone, 17-β Estradiole (E2), 17-α Hydroxy Progesterone and also the level of calcium, Triglyceride and cholesterol in females grey mu...

The recruitment of leaping grey mullet, Liza saliens juveniles in the Neretva River estuary (middle eastern Adriatic Sea, Croatia) started in July, was highest in August, decreased in September, and was unobserved later. The juveniles firstly occupied mouths of rivers and channels and then started migrating to more freshwater habitats. By feeding investigation, the harpacticoid copepods were th...

Grey-mullet are heterosexual fish and gonochorism is the general rule. Cytological cnalysis of sex-differentiation was studied by light microscopy (Stenger, 1959 ; Leray, 1968 ; Thong, 1969 ; Cassifour, 1975), but germ-cell characteristics were not sufficiently defined at this level and no distinction could be made between primordial germ-cells, oogonia and spermatogonia. Electron microscopy ha...

Grey mullet, Mugil cephalus L. is an marine teleost suitable for culture in brackish water. To date, very few report on artificial propagation of grey mullet has ever been recorded and still seed stocking relies on wild recruitment. This paper describe the technique of controlled ovarian maturation and artificial spawning in this fish species. The brood stocks were obtained from cultured mature...

The pathogenicity of a Nervous Necrosis Virus isolate obtained from naturally infected Golden grey mullet (Liza auratus) suffering serious mortalities in Iranian coastline water of the Caspian Sea was investigated for first time. An experimental infection has been performed using three groups, two experimental groups and one control group of Guppy (Poecilia reticulata) with mean weight 0.47±0.0...
