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 ...
Scope for growth and dietary needs of Mediteranean Pinnids maintained in captivity
(BMC, 2022-07-27)
Background
The measurement of the energy available for growth (scope of growth, SFG) can be used in bivalves to make a long-term prediction in a short-term experiment of the condition of the individual. ...
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 ...
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 ...
Transcriptome analysis of flathead grey mullet (Mugil cephalus) ovarian development induced by recombinant gonadotropin hormones
(Frontiers Media, 2022-11-01)
Background: Treatment with recombinant gonadotropin hormones (rGths), follicle-stimulating hormone (rFsh) and luteinizing hormone (rLh), was shown to induce and complete vitellogenesis to finally obtain ...
Improved culture enrichment broth for isolation of Arcobacter-like species from the marine environment
(Springer Nature Limited, 2020-09-03)
Arcobacter-like species are found associated with many matrices, including shellfish in marine environments. The culture media and conditions play a major role in the recovery of new Arcobacter-like ...
A transcriptomic analysis of diploid and triploid Atlantic salmon lenses with and without cataracts
(Elsevier, 2020-07-28)
To avoid negative environmental impacts of escapees and potential inter-breeding with wild populations, the Atlantic salmon farming industry has and continues to extensively test triploid fish that are ...
No hybridization and marked interspecific differences in individual growth rate in mixed cultures of Manila clam (Ruditapes philippinarum) and grooved carpet-shell clam (R. decussatus)
(Elsevier, 2021-04-24)
The Manila clam (Ruditapes philippinarum) was introduced in Europe in the 1970's and in the following years it became naturalized. Interactions with the native species include hybridization with the ...
Mapping the knowledge of the main diseases affecting sea bass and sea bream in Mediterranean
(Wiley, 2020-01-21)
Good knowledge on the disease situation and its impact on production is a base mechanism for designing health surveillance, risk analysis and biosecurity systems. Mediterranean marine fish farming, as ...
Diet, Immunity, and Microbiota Interactions: An Integrative Analysis of the Intestine Transcriptional Response and Microbiota Modulation in Gilthead Seabream (Sparus aurata) Fed an Essential Oils-Based Functional Diet
(Frontiers Media, 2021-03-04)
Essential oils (EOs) are promising alternatives to chemotherapeutics in animal production due to their immunostimulant, antimicrobial, and antioxidant properties, without associated environmental or ...
