The importance of pepsin‐like acid protease quantification in aquaculture studies: a revision of available procedures and presentation of a new protocol for its assessment
(Wiley, 2020-02-05)
Assessing the activity of acid pepsin‐like protease is a common procedure in many biological, physiological and nutritional studies in gastric fish species. After reviewing the available literature on ...
The effect of spray‐dried porcine plasma on gilthead seabream (Sparus aurata) intestinal microbiota
(Wiley, 2020-01-24)
The effect of spray‐dried porcine plasma (SDPP) on the intestinal histological organization and autochthonous microbiota composition was evaluated in Sparus aurata. Fish were fed a basal diet (51 g/kg ...
Vibrio mediterranei, a Potential Emerging Pathogen of Marine Fauna: Investigation of pathogenicity using a bacterial challenge in Pinna nobilis and development of a species‐specific PCR
(Wiley, 2020-06-27)
Aims
Extreme mortality events affecting Pinna nobilis, some associated to Vibrio mediterranei, have depleted many populations of this bivalve. The objective of this study was to demonstrate pathogenicity ...
Is a cannibal different from its conspecifics? A behavioural, morphological, muscular and retinal structure study with pikeperch juveniles under farming conditions
(Elsevier, 2020-02-05)
Cannibalism is defined as the act of killing and consuming the whole, or major part, of an individual belonging to the same species, irrespective of its stage of development. Intra-cohort cannibalism ...
The ontogeny of greater amberjack digestive and antioxidant defence systems under different rearing conditions: A histological and enzymatic approach
(Wiley, 2020-09-23)
An overall synchronization of morphological and physiological ontogenetic events of the digestive and antioxidant defence systems occurred in greater amberjack (Seriola dumerili) larvae reared under ...
The onset of piscivory in a freshwater fish species: analysis of behavioural and physiological traits
(Wiley, 2020-03-12)
The onset of piscivory in fish, resulting in a shift from zooplankton or invertebrate to fish prey, was studied on pikeperch (Sander lucioperca) larvae displaying and not displaying piscivorous behaviour ...
Utilization of grape seed oil as a dietary lipid source in rainbow trout (Oncorhynchus mykiss) diets
(Taylor and Francis, 2020-02-05)
A 60-day feeding trial was conducted to determine the effects of different levels of grape seed oil (GO) on growth performance, digestive enzyme activity, fillet proximate and fatty acid composition of ...
Pinna nobilis in suboptimal environments are more tolerant to disease but more vulnerable to severe weather phenomena
(Elsevier, 2020-11-30)
We examined a disease outbreak of the fan mussel, Pinna nobilis (L.), in the Alfacs Bay (South Ebro Delta, Spain) during a period of two years in three zones exposed to a summer salinity gradient resulting ...
Gambierdiscus and Fukuyoa as potential indicators of ciguatera risk in the Balearic Islands
(Elsevier, 2020-10-22)
Gambierdiscus and Fukuyoa are genera of toxic dinoflagellates which were mainly considered as endemic to marine intertropical areas, and that are well known as producers of ciguatoxins (CTXs) and ...
Growth of juvenile Pinna nobilis in captivity conditions: Dietary and pathological constraints
(Elsevier, 2020-02-25)
The fan mussel, Pinna nobilis, is an endemic Mediterranean species, whose populations have been seriously affected by infectious diseases. The effect of diet composition on growth and survival rates, ...
