Oxidative stress and antioxidant defenses after prolonged starvation in Dentex dentex liver.

The 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...

Dietary intake of probiotics and maslinic acid in juvenile dentex (Dentex dentex L.): effects on growth performance, survival and liver proteolytic activities

Two feeding trials were carried out to evaluate the efficiency of probiotics and maslinic acid, on growth and survival of juvenile dentex; liver proteolytic activities were also investigated in the second trial. For experiment 1, triplicate groups were fed six diets with two probiotics (Bacillus toyoi, T, and B. cereus, E) at increasing levels (0.5, 1 and 2 g kg diet) and a control diet. Growth...

Disinfection of Gilthead Sea Bream (Sparus aurata), Red Porgy (Pagrus pagrus), and Common Dentex (Dentex dentex) Eggs from Sparidae with Different Disinfectants

The aim of this study is to determine suitable conditions for egg disinfection of gilthead sea bream (Sparus aurata), red porgy (Pagrus pagrus), and common dentex (Dentex dentex) with glutaraldehyde, hydrogen peroxide and iodine. The eggs were disinfected with 200 ppm glutaraldehyde (T= 2, 4, 8, 16 min), 300 ppm hydrogen peroxide and iodine (T= 5, 10, 15, 20 min) at four different contact times...

Comparative analysis of artisanal and recreational fisheries for Dentex dentex in a Marine Protected Area

Dentex carpenteri, a new species of deepwater seabream from Western Australia (Pisces: Sparidae).

A new species of sparid fish, Dentex carpenteri, is described from nine type specimens collected off Ningaloo Reef near Exmouth, Western Australia. Four valid species of Dentex are currently known in the western Pacific, Dentex abei and D. hypselosomus in the Northern Hemisphere, and D. fourmanoiri and D. spariformis in the Southern Hemisphere. These four species comprise the "Dentex hypselosom...
