Activ~ties of lactic dehydrogenase (LDH), glutamate oxaloacetate transanunase (GOT) and glutamate pyruvate transaminase (GPT) were measured in blood plasma and some tissues of grey mullet Mugd auratus Risso. After determination of optimal assay conditions, cardiac sampling for LDH estimation was recommended. Tissue distribution of enzymers and their origln in plasma were described, in particula...

Using an (AG)13 enriched genomic library of Mugil cephalus, 12 polymorphic microsatellite loci were isolated and characterized in a test population; the number of alleles ranged from 2 to 11. The observed and expected heterozygosities ranged from 0.2593 to 0.8966 and from 0.3047 to 0.8454, respectively. Two loci deviated from Hardy-Weinberg equilibrium; linkage disequilibrium among the 12 loci ...

Climate fluctuations affect a wide range of environmental factors that may impact fish populations with various response mechanisms. For major part world fisheries stocks, only abundance time-series are available. Relations between these species and ocean variables, including long term trends patterns seasonal change, remain sparsely documented. The main aim our work is to determine what extent...

The ability to observe and predict trawling-induced patterns at spatial and temporal scales that are relevant to inform realistic management strategies is a challenge which scientists have consistently faced in recent decades. Here, we use fish feeding behaviour, a biological trait easily impaired by trawling disturbance, to depict alterations in fish condition (i.e. individual fitness) and fee...

A technique for the demonstration of myofibri1lar adenosine triphosphatase activity (A TPase) used for mammalian muscle has been modified to suit fish muscle. The mammalian method involves selectively inhibit...

Vibrio spp. are gram-negative, facultative anaerobic, non-spore-forming bacilli which are oxidase positive and halophilic bacteria widely spread in seaand brackwater worldwide. The genus Vibrio includes several foodborne pathogens which cause a spectrum of clinical conditions including septicaemia, cholera and milder forms of gastroenteritis. The species most commonly associated with foodborne ...

The temperature behavior of the natural microflora on the Mediterranean fish red mullet (Mullus barbatus) was examined as a case study. The growth of the spoilage bacteria Pseudomonas spp., Shewanella putrefaciens, Brochothrix thermosphacta, and lactic acid bacteria was modeled as a function of temperature and the concentration of carbon dioxide in modified atmosphere packaging. Combined models...
