The hypothalamus-pituitary-interrenal (HPI) axis, involved in the regulation of the neuroendocrine stress responses, presents important players such as corticotropin-releasing hormone (CRH, generally considered as the initiator of this pathway) and CRH-binding protein (CRH-BP, considered as an antagonist of CRH function). CRH and CRH-BP full-length cDNA sequences were obtained from Sparus aurat...

The presence of a Raphidascarid parasitic nematode Hysterothylacium aduncum (Rudolphi, 1802) in two sparid fish (Sparus aurata and Diplodus vulgaris) and one soleid fish (Solea solea) was investigated in this study. A total of 868 individuals; 385 S. aurata, 437 D. vulgaris and 46 S. solea were collected from the Mersin Bay between February 2013 and January 2014 and examined. Variations in the ...

Two new species of Martintella Artigas, 1996, Martintella aurata sp. nov. and Martintella fernandoi sp. nov., from Costa Rica are described and illustrations of species of the genus are provided.

The bioaccumulations of metals Cu, Cd, Ni, Cr, Co, Mn, Zn and Fe were measured in bivalves, Cerastoderma glucaum, and four species of fishes including Alburnus chalcoides, Liza aurata, Rutilus frisii and Sander lucioperca from various trophic levels of the Caspian food web. The concentrations of Cd, Cr, Co and Ni in most samples of fish were below the detection limits; while the concentrations ...

Reducing the dependency of fishfeed for marine ingredients and species diversification are both considered crucial factors sustainable development aquaculture. The substitution fish oil (FO) by vegetable oils (VO) in aquafeeds is an economically feasible solution. However, such may compromise flesh content essential n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) and, therefore, its nu...
