Sagittal otolith shape analysis is one of the most widespread techniques worldwide to discriminate fish stock units, as this proxy integrates both environmental and genetic factors. All previous studies have been carried out using two-dimensional (2D) images, a partial representation whole otolith. However, prior identification unit boundaries, influence other potential drivers controlling must...

Small seine net fish assemblages in the headwater region of the Kariega Estuary are described and compared to the catch composition in other parts of the system. The geographical headwaters of the freshwater ‘deprived’ Kariega Estuary were utilised by a range of fish species but, in contrast to the nearby freshwater ‘rich’ Great Fish Estuary, few important angling species (e.g. spotted grunter ...

A survey of Myxosporidia in teleosts from the South-Western. coast of England demonstrated the widespread occurrence of these parasites. Infection in selected fish ·species was related to age, sex and seasonal migration of the host. Structural studies of Myxobolus exiguus and Myxidium incurvatum were undertaken in order to investigate sporogenesis, parasite development and-the host-parasite int...

To elucidate the effects of seasonal variation of precipitation on the distribution of polychlorinated biphenyls (PCBs) in estuarine sediments and benthic feeders, PCB concentrations of river surface sediments and mullet fish (Liza macrolepis) were investigated in the estuary of Er-Jen River near former PCB contamination sites before and after each wet season from 2002 to 2004. Analyses of grai...

This study was carried out in 13 fishing operations the inner harbor area of Sinop, from September through November 2004. Trammel nets were used, which has 32 mm mesh size and target fish species gear is red mullet (Mullus barbatus) study. Three net groups used experiments, without selvedge (A0) for control net, multifilament with (A1) monofilament (A2) respectively. 65.3% Osteichthyes (696 ind...

Gyrodactylus aff. mugili Zhukov, 1970 (Monogenoidea: gyrodactylidae) is recorded and described from the gill lamellae of 11 of 35 greenback mullet, Chelon subviridis (Valenciennes) (minimum prevalence 31%), from the brackish waters of the shatt Al-Arab Estuary in southern iraq. the gyrodactylid was also found on the gill lamellae of one of eight speigler’s mullet, Valamugil speigleri (Bleeker),...

grey mullet (mugil cephalus) is an important food fish species in the, mugilidae which is able to adapt in a wide range of salinities and temperatures and is suitable for introduction of the species to freshwater, brackish, and brine waters for aquaculture. this study was implemented to determine appropriate normative of stocking density and initial weight ofmugil cephalus and also evaluate eff...

The study describes the infection of the acanthocephalan, Neoechinorhynchus agilis sp. The (grey mullet) Mugil cephalus is highly valued food along the Corentyne coast, Berbice, Guyana. The fish Mugil cephalus were collected from Bush Lot, Whim, 43 Village 63 Beach and 79 Village, Corentyne coast. The infections with the parasites were observed in posterior region of the intestine, liver and mu...

The main objective for the present research was to assess the effect of cyclic starvation and L- carnitine supplementation on growth (body final weight, hepatosomatic index (HSI), daily growth rate (DGI), feed conversion ratio (FCR) and voluntary feed intake (VFI)), body composition (crude protein, crude lipid, ash and moisture), biochemical (plasma total protein, glucose, cholesterol, triglyce...
