Development of a Method to Extract and Amplify the Complete Mitogenome of Some Sparidae Species
Previous studies showed that fish mitochondrial DNA (mtDNA) is set up by a closed circular molecule of 16-17 kilobases (kb), comprising 2 ribosomal RNA genes (rRNA), 22 transfer RNA genes (tRNA), 13 protein-coding genes and 2 non-coding regions. The analysis of single mtDNA genes, such as Cytb, COI, 16S and 12S, or short segment of them, has been widely used against species substitution in both...
متن کاملSpearfishing Regulation Benefits Artisanal Fisheries: The ReGS Indicator and Its Application to a Multiple-Use Mediterranean Marine Protected Area
The development of fishing efficiency coupled with an increase of fishing effort led to the overexploitation of numerous natural marine resources. In addition to this commercial pressure, the impact of recreational activities on fish assemblages remains barely known. Here we examined the impact of spearfishing limitation on resources in a marine protected area (MPA) and the benefit it provides ...
متن کاملOxidative stress and antioxidant defenses after prolonged starvation in Dentex dentex liver.
The aim of this work was to evaluate the effects of prolonged starvation and refeeding on antioxidant status and some metabolic-related parameters in common dentex (Dentex dentex) liver. Fish deprived of food for 5 weeks showed a significant increase in lipid peroxidation, measured as malondialdehyde (MDA) levels. The activity of the antioxidative enzymes superoxide dismutase (SOD), catalase, a...
متن کاملThe intensity of electrophoretic bands containing egg non-vitellogenin derived proteins in relationship with embryo-larvae viability in common dentex (Dentex dentex) a preliminary evaluation
Despite the reported effects of egg vitellogenin-derived proteins (VtgDP) and amino acids on embryo-larvae viability in common dentex the effects of non-vitellogenin-derived proteins (non-Vtg-DP) has yet to be determined. As an initial study, fertilized eggs (70 batches) were provided by natural spawning of broodfish in captivity. Viability parameters (VP) such as egg floating, hatching, and la...
متن کاملShift in trophic level of Mediterranean mariculture species.
The mean trophic level of the farmed fish species in the Mediterranean has been increasing. We examined the farming-up hypothesis (i.e., the increase in the production of high-trophic-level species) in the Mediterranean by determining the trophic level of the aquafeeds (i.e., what the fish are fed) of 5 species of farmed marine fishes: common dentex (Dentex dentex), common pandora (Pagellus ery...
