Physiological processes modulate acute and chronic responses to dietary protein/energy ratio fluctuations in individuals and families of Manila clam (Ruditapes philippinarum) selected for variable growth rates
(Elsevier, 2020-01-31)
A range of phenotypes differing in growth rate were designed in the Manila clam by combining separate breeding families with size segregation within each family to constitute fast and slow growing groups. ...
Emergence and clonal expansion of Vibrio aestuarianus lineages pathogenic for oysters in Europe
(Wiley, 2023-03-01)
Crassostrea gigas oysters represent a significant global food source with 4.7 million tons harvested per year. In 2001, the bacterium Vibrio aestuarianus subsp. francensis emerged as a pathogen that ...
Reproduction of the endangered fan mussel Pinna nobilis under natural and captivity conditions
(Wiley, 2023-09-05)
1. A mass mortality event that started in 2016 has put the fan mussel Pinna nobilis close to the brink of extinction, leading to the species being classified as Critically Endangered in the Red List of ...
Lipid and fatty acid composition of muscle, liver, ovary, and peritoneal fat in wild flathead grey mullet (Mugil cephalus) according to ovarian development
(Elsevier, 2022-12-30)
Wild adult females of a low trophic omnivore teleost species, the flathead grey mullet (Mugil cephalus), caught in the western Mediterranean were sampled. The lipid and fatty acid composition of ovaries, ...
Brewers’ Spent Yeast and Grain Protein Hydrolysates as Second-Generation Feedstuff for Aquaculture Feed
(Springer Verlag, 2020-07-07)
Aquafeeds are formulated to contain all the essential nutrients that fishes need to keep healthy. They are highly dependent on marine ingredients: fish meal and oil. Hence, alternative ingredients which ...
Reproductive behaviour and fertilized spawns in cultured Solea senegalensis broodstock co-housed with wild breeders during their juvenile stages
(Elsevier, 2024-05-07)
The reproductive failure of Senegalese sole (Solea senegalensis) cultured males (reared entirely in captivity from egg through to adult) that do not participate in reproductive behaviours to fertilise ...
Ecodesign of new circular economy scheme for Brewer's side streams
(Elsevier, 2022-05-25)
When designing a new circular economy system, many aspects must be considered in order to benefit from all possible environmental improvements. The selection of the right market or use of the resulting ...
Seasonal-and dose-dependent effects of recombinant gonadotropins on sperm production and quality in the flatfish Solea senegalensis
(Elsevier, 2018-07-02)
Consecutive treatments with recombinant follicle-stimulating and luteinizing hormones (rFsh and rLh, respectively) stimulate spermatogenesis and potentiate sperm production in pubescent specimens of the ...
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 ...
Hemato-Immunological and plasma biochemical responses of silvery-black porgy (Sparidentex hasta) fed protein and essential amino acid deficient diets
(Springer, 2017-09-09)
A six-week feeding trial was conducted to evaluate the effects of protein free (PF) and essential amino acid deficient (EAAD) diets on the physiological responses of silvery-black porgy (Sparidentex ...
