Mating behaviour and gamete release in gilthead seabream (Sparus aurata, Linnaeus 1758) held in captivity
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2015-02-11)
The present study aimed to describe the reproductive behaviour of gilthead seabream (Sparus aurata) in captivity. Twenty-four mature gilthead seabream, divided in two tanks, were utilized for the present ...
Exploring patterns of variation in amphipod assemblages at multiple spatial scales: natural variability versus coastal aquaculture effect
(Inter Research, 2013-01-03)
A 5-factor design survey was carried out to examine the spatial distribution at different scales of amphipod assemblages and sedimentary variables in soft bottoms adjacent to coastal aquaculture ...
Stressors due to handling impair gut immunity in meagre (Argyrosomus regius): the compensatory role of dietary L-Tryptophan
(Frontiers Media, 2019-05-10)
In the context of intensive aquaculture, meagre (Argyrosomus regius) is one of the most important new aquaculture species in Southern Europe and several studies are focused on the optimization of its ...
Reproductive performance of captive Senegalese sole, Solea senegalensis, according to the origin (wild or cultured) and gender
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2019-11-22)
Aim of study: The reproductive performance over a five year period in three different sole broodstocks: wild males with cultured females (WM), cultured males with wild females (CM), and a control of ...
Mitochondrial aquaporin-8-mediated hydrogen peroxide transport is essential for teleost spermatozoon motility
(Nature Research, 2015-01-14)
Reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2), cause oxidative cell damage and inhibit sperm function. In most oviparous fishes that spawn in seawater (SW), spermatozoa may be ...
Arachidonic Acid and Eicosapentaenoic Acid Metabolism in Juvenile Atlantic Salmon as Affected by Water Temperature
(Public Library of Science, 2015-11-24)
Salmons raised in aquaculture farms around the world are increasingly subjected to suboptimal environmental conditions, such as high water temperatures during summer seasons. Aerobic scope increases and ...
Souffle/Spastizin Controls Secretory Vesicle Maturation during Zebrafish Oogenesis
(Public Library of Science, 2014-06-26)
During oogenesis, the egg prepares for fertilization and early embryogenesis. As a consequence, vesicle transport is very active during vitellogenesis, and oocytes are an outstanding system to study ...
Normal and histopathological organization of the opercular bone and vertebrae in gilthead sea bream Sparus aurata
(Inter Research, 2014-06-18)
This study provides a comprehensive description of the tissue organization of nondeformed and deformed opercula and vertebrae from gilthead sea bream Sparus aurata juveniles by means of histological, ...
Dose-dependent effect of a single GnRHa injection on the spawning of meagre (Argyrosomus regius) broodstock reared in captivity
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentari, 2014-10-27)
The present study aimed to determine the spawning efficacy, egg quality and quantity of captive breed meagre induced with a single gonadotrophin-releasing hormone agonist (GnRHa) injection of 0, 1, 5, ...
