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 ...
An Endeavor to Find Starter Feed Alternatives and Techniques for Zebrafish First-Feeding Larvae: The Effects on Viability, Morphometric Traits, Digestive Enzymes, and Expression of Growth-Related Genes
(Mary Ann Liebert, 2021-02-12)
Low and variable growth and survival rates (SR) of 6–10 days postfertilization zebrafish larvae are a problem. This problem seems to be linked to starter feed characteristics. This study is an attempt ...
Vibrio eleionomae sp. nov., isolated from shrimp (Penaeus vannamei) pond water
(Microbiology Society, 2023-05-11)
A novel Vibrio strain (CAIM 722T=SW9T=DSM 24596T) was isolated in 2003 from water of a shrimp (Penaeus vannamei) culture pond located in Los Mochis, Sinaloa, Mexico, and taxonomically characterized using ...
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 ...
Isolation, identification, and gene expression analysis of the main digestive enzymes during ontogeny of the Neotropical catfish Pseudoplatystoma punctifer (Castelnau, 1855)
(Elsevier, 2021-06-09)
The ontogeny of the digestive capacities in fish is species-specific and its knowledge is essential for understanding the nutritional requirements of fish larvae. While the Amazon basin contains the ...
A re-evaluation of conflicting taxonomic structures of Eurasian Triaenophorus spp. (Cestoda, Bothriocephalidea: Triaenophoridae) based on partial cox1 mtDNA and 28S rRNA gene sequences
(Canadian Science Publishing, 2022-07-13)
Cestodes of the genus Triaenophorus Rudolphi, 1793 are widely distributed parasites of Esocidae, Percidae, Salmonidae, Thimallidae, Cobitidae, Osmeridae, Cyprinidae, Cottiidae, Lotidae, and several ...
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 ...
Digestive enzyme activities during pejerrey (Odontesthes bonariensis) ontogeny
(Elsevier, 2020-02-22)
The first step for assessing and refining the nutritional requirements during the larval and early juvenile stages of a fish is the study of the ontogeny of digestive system functionality. The combination ...
