Transcriptomic evidences of local thermal adaptation for the native fish Colossoma macropomum (Cuvier, 1818) [PDF]

Genetics and Molecular Biology, 2020
Brazil has five climatically distinct regions, with an annual average temperature difference up to 14 ºC between the northern and southern extremes. Environmental variation of this magnitude can lead to new genetic patterns among farmed fish populations.

Growth Performance and Histomorphology of Intestine, Skin, Gills and Liver of Juvenile Colossoma macropomum Fed Diets Containing Different Levels of the Essential Oil of Nectandra grandiflora

Fishes, 2023
The present study evaluated different levels of the essential oil of Nectandra grandiflora (EONG) in the diet of juvenile Colossoma macropomum. The juveniles (0.75 ± 0.05 g) were fed four experimental diets with differing levels of EONG (0, 0.5, 0.75 ...

Influence of guava residue on tambaqui growth performance

Acta Scientiarum. Animal Sciences, 2022
Fruit residues represent alternative ingredients that can be included in diets of tambaqui, Colossoma macropomum. This study evaluated the growth performance of tambaqui fed diets containing different levels of guava agroindustrial residue. The experiment was based on a completely randomised design, with 105 fish randomly distributed in 15 plastic 60 L-

Impact of Cryopreservation Extenders on Epigenetic Changes in Bull Sperm: H19 and MEG3 Methylation. [PDF]

Vet Med Sci
This study compared the cryoprotective effects of soy lecithin (SLE) and egg yolk (EYE) extenders on post‐thaw bull sperm quality and the methylation status of imprinted genes H19 and MEG3. The visual abstract outlines the experimental workflow: Bull sperm collection, dilution with either SLE or EYE extenders, followed by cryopreservation (symbolized ...
