The catch composition of bottom trawls is commonly refined and improved through changes in codend design. Measures like reducing the number meshes circumference or turning diamond netting by 90 degrees are well known to improve size selectivity fish species with rounded cross-sectional shape. Based on this we speculated whether same measures, if applied other parts a trawl, would provide simila...

A part of the Raša Bay (western Croatia) is an estuary that fed by sediment load from River. The local area had been affected former coal industry. aim this study was to determine levels hazardous trace elements (HTEs) in bottom estuarine sediments, fish and mussels collected two sites downstream River mouth, a wild boar’s kidney donated hunters. pseudo-total concentrations 21 HTEs sediments we...

The aim of this research was to investigate the effects of the oral administration of Gum Arabic on haematological and some oxidative stress markers in Mugil cephalus. For this purpose 60 mullet caught in Faro Lake (Italy), were acclimatized and fed with commercial diet for 20 days prior to the start of experiment, which lasted 15 days. After acclimatization, fish were randomly divided into two...

Some reproduction characteristics of keeled mullet, Liza klunzingeri, were studied during Apr. 2003 to Feb. 2004 in Khuzestan waters of the Persian Gulf. A total of 836 samples were monthly collected from two fish landings of Bahrekan and Hendijan; 727 specimens were studied from point of sex determination, and 60 specimens were studied from the fecundity point of view. This species was found ...

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...

Length-weight relationships (LWR) were described for fourteen demersal and pelagic fish species; whiting (Merlangius merlangus), red mullet (Mullus barbatus), picarel (Spicara maena), scorpion (Scorpaena porcus), anchovy (Engraulis encrasicolus), sprat (Sprattus sprattus), horse mackerel (Trachurus mediterraneus), bluefish (Pomatomus saltatrix), turbot (Scophthalmus maximus), thornback ray (Raj...

Beta-defensins are important part of innate immunity of fish, which are the first defense line against invading pathogens. In this study, the β-defensin (Lhβ-defensin) gene was cloned from spleen tissue of soiny mullet (Liza haematocheila). Lhβ-defensin cDNA was 747 bp in length, encoding 63 amino acids. Sequence alignment revealed that Lhβ-defensin contained six conserved cysteine residues and...

the present study was carried out in 2011 to measure concentration of heavy metals chromium and tin in liver and muscle tissue of liza aurata (golden grey mullet) in estuaries of the rivers babolroud, tajan and gorganroud. accordingly, after sampling the target are asandisolating muscle (18samples) and liver (18samples) tissues, they were digested and analyzed using graphite furnace atomic abso...

The grey mullet is a catadromous species that spawns in the taurine-rich seawater environment, followed by young fish generally migrating to less saline, low taurine waters during larva-juvenile transition. Consequently, this study aimed (1) determines whether there dietary requirement juvenile for enhanced growth and (2) potential biosynthesis. experimental system consisted of sixteen 400-l V-...
