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 ...
Temperature affects growth allometry and development patterns in brown trout (Salmo trutta) fry: a multitrait approach
(NRC Research Press, 2017-07-17)
To study the influence of temperature (4, 6, and 12 °C) on the development of brown trout (Salmo trutta) from hatching to the end of metamorphosis, an analysis of allometric growth patterns was conducted ...
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 ...
Paired spawning with male rotation of meagre Argyrosomus regius using GnRHa injections, as a method for producing multiple families for breeding selection programs
(Elsevier, 2018-06-08)
Weekly gonadotropin-releasing hormone agonist (GnRHa) injections were used to induce spawning in paired male and female meagre (Argyrosomus regius) with a weekly rotation of the males, in order to produce ...
Detection of tetrodotoxins in juvenile pufferfish Lagocephalus sceleratus (Gmelin, 1789) from the North Aegean Sea (Greece) by an electrochemical magnetic bead-based immunosensing tool
(Elsevier, 2019-03-29)
Two small Lagocephalus sceleratus juveniles were captured in picarel targeting catches from North Aegean Sea (Greece) in the autumn of 2017. An electrochemical immunosensing tool using magnetic beads ...
Zebrafish as a Model to Screen the Potential of Fatty Acids in Reproduction
(Mary Ann Liebert, 2019-01-31)
Sperm quality is an important topic in general health, chemotherapy, and gamete preservation technology. Fatty acid (FA) composition of membranes, which is influenced by the diet, plays key roles in ...
Dietary nucleotide mixture effects on reproductive and performance, ovary fatty acid profile and biochemical parameters of female Pacific shrimp Litopenaeus vannamei
(Wiley, 2017-06-22)
The effects of different dietary nucleotide mixture (NT) levels (0, 2, 4 and 6 g/kg) were investigated on the reproductive performance, fatty acid profile and biochemical parameters in Litopenaeus ...
Variations of the intestinal gut microbiota of farmed rainbow trout, Oncorhynchus mykiss (Walbaum), depending on the infection status of the fish
(Wiley, 2019-05-07)
Aims
The aim of the present study was to investigate the composition of the intestinal microbiota during the acute stage of a bacterial infection to understand how dysbiosis of the gut may influence ...
