Animal-associated microbiotas form complex communities, which are suspected to play crucial functions for their host fitness. However, the biodiversity of these communities, including their differences between host species and individuals, has been scarcely studied, especially in case of skin-associated communities. In addition, the intraindividual variability (i.e. between body parts) has neve...

Aquaporin (AQP)-mediated intestinal water absorption may play a major osmoregulatory role in euryhaline teleosts, although the molecular identity and anatomical distribution of AQPs in the fish gastrointestinal tract is poorly known. Here, we have investigated the functional properties and cellular localization in the intestine of two gilthead seabream (Sparus aurata) homologs of mammalian aqua...

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...

Growth is a priority trait from the point of view of genetic improvement. Molecular markers linked to quantitative trait loci (QTL) have been regarded as useful for marker-assisted selection in complex traits as growth. Polymorphisms have been studied in five candidate genes influencing growth in gilthead seabream (Sparus aurata): the growth hormone (GH), insulin-like growth factor-1 (IGF-1), m...

Vibrioses caused by different members of the genus Vibrio are common diseases in aquaculture characterised systemic infections, high mortalities, and economic losses fish shellfish. Farming European sea bass (Dicentrarchus labrax) gilthead seabream (Sparus aurata) has rapidly grown over last decade Croatia but its efficacy is significantly jeopardized due to anguillarum harveyi infection. There...

This study compares the farm management model used in Mediterranean gilthead seabream (GHSB; Sparus aurata) industry (S1)—stepped entry of juveniles throughout year with several production cycles and fish ages overlapping a single farm—with that salmon (S2)—the whole is filled are same age at once fallowing period between rearing cycles—in terms waste by coupling digestibility coefficients grow...

One of the effects of fisheries on ecosystems is that they tend to remove the larger, higher-trophic-level species and thus progressively lower the mean trophic level (TL) of the landings. This effect is known as “fishing down the food web” (Pauly et al. 1998; but see also Essington et al. [2006] for addition of low-TL fisheries instead of decline in high-TL fisheries, termed “fishing through m...
