the main objective of the present study was qualitative assessment of golden gray mullet stocks by using indicators of overfishing in iranian waters of the caspian sea during a long period (1991-2011). three fisheries indicators in catch were: 1. percentage of mature fish, with 100% as target; 2. percent of specimens with optimum length, with 100% as target; and 3. percentage of mega-spawners, ...

The population dynamics of pseudomonads in gilt-head sea bream Mediterranean fish (Sparus aurata) stored under different conditions were studied. Phenotypic analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis of whole-cell proteins were performed to identify a total of 106 Pseudomonas strains isolated from S. aurata stored under different temperatures (at 0, 10, and 20 degree...

Comparisons were made of metal concentrations in water and sediment with those in the muscle and livers of three species of fish caught in four seawater reservoirs (two in the Odiel estuary and two in the Bay of Cádiz). The concentrations of a large number of metals in the water, sediment and fish were higher in the Odiel reservoirs than in those in Cádiz. We found high metal-enrichment factors...

the genus trachylepis fitzinger, 1843 encompasses two-three species in iran: trachylepis vittata (olivier, 1804) distributed in western iran, west of the zagros mountains; t.septemtaeniata (reuss, 1834) in southern regions of the zagros mountains and t. aurata transcaucasica chernov, 1926 from northern to central parts of the zagros mountains. for study of geographic variation in the latter two...

The effect of acute handling stress on haematological profile, blood glucose and lactate (secondary stress markers) in cultured sea bream Sparus aurata was evaluated. Sixty six Sparus aurata were used and equally divided into two groups (A and B). Group A was not subjected to stress, Group B was subjected to acute handling stress. From each fish, biometric data and blood samples were collected ...

Neurotoxicity induced in fish by domoic acid (DA) was assessed with respect to occurrence of neurotoxic signs, lethality, and histopathology by light microscopy. Sparus aurata were exposed to a single dose of DA by intraperitoneal (i.p.) injection of 0, 0.45, 0.9, and 9.0 mg DA kg(-1) bw. Mortality (66.67 ± 16.67%) was only observed in dose of 9.0 mg kg(-1) bw. Signs of neurological toxicity we...

Given the pivotal role of Platelet-Activating-Factor (PAF) in atherosclerosis and the cardio-protective role of PAF-inhibitors derived from olive pomace, the inclusion of olive pomace in fish feed has been studied for gilthead sea bream (Sparus aurata). The aim of the current research was to elucidate the anti-atherogenic properties of specific HPLC lipid fractions obtained from olive pomace, o...

This study describes the development and validation of an enriched oligonucleotide-microarray platform for Sparus aurata (SAQ) to provide a platform for transcriptomic studies in this species. A transcriptome database was constructed by assembly of gilthead sea bream sequences derived from public repositories of mRNA together with reads from a large collection of expressed sequence tags (EST) f...
