(NRC Research Press (Canadian Science Publishing), 2021-11-05)
The Coregonus lavaretus (Linnaeus, 1758) complex is a morphologically and genetically diverse group of whitefish. Its taxonomic structure has been controversial for almost a century. At least 25 forms ...
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 ...
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 ...
Narrow versus broad: sexual dimorphism in the wing form of western European species of the subgenus Avaritia (Culicoides, Ceratopogonidae)
(Wiley, 2021-01-12)
While wing form is known to differ between males and females of the genus Culicoides, detailed studies of sexual dimorphism are lacking. In this study, we analyze sex-specific differences in the wing ...

(Wiley, 2021-05-08)
Bluetongue (BT) is an emerging and re-emerging communicable vector-borne disease of animal health concern. A serosurvey was performed to assess exposure to BT virus (BTV) in zoo animals in Spain and to ...
Stable neutralizing antibody levels 6 months after mild and severe COVID-19 episodes
(Elsevier, 2021-01-31)
Background. Understanding mid-term kinetics of immunity to SARS-CoV-2 is the cornerstone for public health control of the pandemic and vaccine development. However, current evidence is rather based on ...
Complete feed versus concentrate and straw fed separately: Effect of feeding method on eating and sorting behavior, rumen acidosis, and digestibility in crossbred Angus bulls fed high-concentrate diets
(Elsevier, 2021-01-06)
The aim of this study was to evaluate the effect of feeding method on eating and sorting behavior, rumen acidosis, and apparent total tract digestibility of crossbred Angus bulls fed a high-concentrate ...
Effects of the application of a moderate alternate wetting and drying technique on the performance of different European varieties in Northern Italy rice system
(Elsevier, 2021-07-03)
Alternate wetting and drying (AWD) technique has been developed and evaluated on rice (Oryza sativa) systems in several countries worldwide for increasing water use efficiency and reducing negative ...
Development, nutrition, and rearing practices of relevant catfish species (Siluriformes) at early stages
(Wiley, 2021-06-17)
Catfish (Siluriformes) are important species for aquaculture worldwide, with an annual production in 2018 of ca. 6 million t. This review focuses on reassessing larval development, first feeding, and ...
