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 ...
Skin mucus metabolites in response to physiological challenges: A valuable non-invasive method to study teleost marine species
(Elsevier, 2018-07-13)
Knowledge concerning the health and welfare of fish is important to conserve species diversity. Fish mucosal surfaces, and particularly the skin, are of utmost importance to protect the integrity and ...
Temperature responsiveness of gilthead sea bream bone; an in vitro and in vivo approach
(Springer Nature, 2018-07-25)
This study aimed to characterize the molecules involved in osteogenesis in seabream and establish using in vitro/in vivo approaches the responsiveness of selected key genes to temperature. The impact ...
Rapid capture and detection of ostreid herpesvirus-1 from Pacific oyster Crassostrea gigas and seawater using magnetic beads
(Public Library of Science, 2018-10-03)
Ostreid herpesvirus-1 (OsHV-1) has been involved in mass mortality episodes of Pacific oysters Crassostrea gigas throughout the world, causing important economic losses to the aquaculture industry. In ...
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 ...
Neglecting the fallow season can significantly underestimate annual methane emissions in Mediterranean rice fields
(Public Library of Science, 2018-05-31)
Paddy rice fields are one of the most important sources of anthropogenic methane. Improving the accuracy in the CH4 budget is fundamental to identify strategies to mitigate climate change. Such improvement ...
Linking fish-based biological indicators with hydrological dynamics in a Mediterranean river: Relevance for environmental flow regimes
(Elsevier, 2018-08-07)
The relationship between flow dynamics and biological communities becomes especially relevant in Mediterranean rivers. Given their natural variability and growing anthropogenic pressures, their low ...
Global-change effects on early-stage decomposition processes in tidal wetlands – implications from a global survey using standardized litter
(Copernicus Publications, 2018-05-30)
Tidal wetlands, such as tidal marshes and mangroves, are hotspots for carbon sequestration. The preservation of organic matter (OM) is a critical process by which tidal wetlands exert influence over the ...
