The flathead grey mullet ( Mugil cephalus ) is at the focus of an intense domestication effort. However, despite significant advances, aquaculture mullets still based on capture wild fingerlings in estuaries and stocking them into ponds. Such reliance seed limits production since it highly seasonal, unpredictable, hinders genetic improvement programs may negatively affect local fisheries. As ca...

This work describes the ontogeny of the digestive tract in thick lipped grey mullet (Chelon labrosus) larvae reared until day 36 post-hatching with the semi-extensive technology in mesocosms. Diet was constituted by live preys, rotifers, Artemia and wild zooplankton, then compound diet was added from day 20 (p. h.). Linear growth, weight growth and digestive enzymes specific activities were stu...

mercury is the most toxic heavy metal in the aquatic ecosystems which originates both from natural and industrial resources and is ultimately deposited in sediments as methyl mercury. this metal is quickly transferred through the food chain and accumulated in organisms. in this study, the human health risk due to consumption of mullet ( liza aurata ) in the caspian sea, were evaluated by measur...

The objective of this study was to determine the liver oxidative stress status of grey mullets living in heavy-metal-rich polluted Ennore estuary compared with unpolluted Kovalam estuary. Fish were collected from both estuaries during the monsoon and summer seasons from October 2004 to September 2006. Fish liver homogenate (N = 20 per group) was prepared for evaluating oxidative stress paramete...

A dot-blot immunoassay for the detection of vitellogenin (Vtg) in plasma of adult grey mullet (Mugil cephalus) was developed. The assay identified the sex of the tested fish prior to detectable gonadal development, enabling the establishment of broodstock at the desired ratio of 7:4 females to males. This broodstock was maintained under natural photoperiod, and used to study the relative effect...
