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 ...
Variations in Bacterial Community of Rearing Water and Gut of Common Dentex, Dentex dentex (Linnaeus 1758), Larvae Using Three Microalgae Management Approaches
(Wiley, 2017-05-30)
Microorganisms present in the rearing water colonize the gut of first feeding larvae and represent the first barrier against opportunistic pathogens. The aim of the experiments presented herein was to ...
The feasibility of using gas mixture to stun seabream (Sparus aurata) before slaughtering in aquaculture production
(Elsevier, 2021-07-10)
Current European Union regulation explicitly states that farmed fish should be spared any avoidable pain, distress or suffering at the time of slaughter. It has been shown that fish suffer when they are ...
Meta‐analysis approach to the effects of live prey on the growth of Octopus vulgaris paralarvae under culture conditions
(Wiley, 2016-02-14)
The common octopus (Octopus vulgaris, Cuvier 1797) is a promising species for aquaculture diversification, but the massive mortality during the first life stage is the main bottleneck for its commercial ...
Temperature effects on the growth and survival of tdh positive Vibrio parahaemolyticus in tissues of postharvest Manila clam (Ruditapes philippinarum)
(Elsevier, 2017-10-31)
Bivalve storage at inadequate temperatures contains greater densities of Vibrio parahaemolyticus. The objective of the present study was to determine if there were any differences in growth and survival ...
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 ...
