First record and evidence of an established population of the North American mud crab Dyspanopeus sayi (Brachyura: Heterotremata: Panopeidae) in the western Mediterranean
(Consejo Superior de Investigaciones Científicas, 2012-03)
The panopeid crab Dyspanopeus sayi (Smith, 1869) is reported here from the Ebro Delta (Mediterranean coast
of the Iberian Peninsula). Originally endemic to the Atlantic coast of North America, D. sayi ...
Developmental RNA-Seq transcriptomics of haploid germ cells and spermatozoa uncovers novel pathways associated with teleost spermiogenesis
(Nature Research, 2022-08-19)
In non-mammalian vertebrates, the molecular mechanisms involved in the transformation of haploid germ cells (HGCs) into spermatozoa (spermiogenesis) are largely unknown. Here, we investigated this process ...
Evaluation of a bacterial single-cell protein in compound diets for rainbow trout (Oncorhynchus mykiss) fry as an alternative protein source
(MDPI, 2020-09-17)
A 60-day trial was conducted in rainbow trout (Oncorhynchus mykiss) fry (initial weight = 2.5 ± 0.6 g) to evaluate the potential use of a bacterial single-cell protein (SCP) as an alternative protein ...
Population genetics of the Manila clam (Ruditapes philippinarum) introduced in North America and Europe
(Nature Research, 2017-01-03)
Globally, the Manila clam (Ruditapes philippinarum) stands as the second most important bivalve
species in fisheries and aquaculture. Native to the Pacific coast of Asia, it is now well-established ...
Consistent habitat segregation between sexes in the spider crabs Maja brachydactyla and Maja squinado(Brachyura), as revealed by stable isotopes
(Consejo Superior de Investigaciones Científicas, 2016-01-20)
Differences in the resource use patterns of males and females of the spider crab species Maja brachydactylaBalss, 1922 and M. squinado (Herbst, 1788) from several geographic areas (three ...
Toward developing recombinant gonadotropin-based hormone therapies for increasing fertility in the flatfish Senegalese sole
(Public Library of Science, 2017-03-22)
Captive flatfishes, such as the Senegalese sole, typically produce very low volumes of sperm. This situation is particularly prevalent in the first generation (F1) of reared sole males, which limits the ...
Insect glycerol transporters evolved by functional co-option and gene replacement
(Nature Research, 2015-07-17)
Transmembrane glycerol transport is typically facilitated by aquaglyceroporins in Prokaryota and Eukaryota. In holometabolan insects however, aquaglyceroporins are absent, yet several species possess ...
Low sperm to egg ratio required for successful in vitro fertilization in a pair-spawning teleost, Senegalese sole (Solea senegalensis)
(The Royal Society, 2021-03-10)
Cultured Senegalese sole (Solea senegalensis) breeders fail to spawn fertilized eggs. The implantation of large-scale in vitro fertilization protocols, to solve this problem, has been frustrated by low ...
Spray-dried plasma promotes growth, modulates the activity of antioxidant defenses, and enhances the immune status of gilthead sea bream (Sparus aurata) fingerlings
(Oxford University Press, 2015-01-01)
Terrestrial animal byproduct meals, including nonruminant blood meal and blood products, represent the largest and largely untapped safe source of animal protein available within the international market ...
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 ...
