(BMC, 2022-02-04)
Background
The decapods are a major group of crustaceans that includes shrimps, prawns, crayfishes, lobsters, and crabs. Several studies focused on the study of the digestive system of the decapods, ...
Trophic diversification and parasitic invasion as ecological niche modulators for gut microbiota of whitefish
(Frontiers, 2023-03-14)
Introduction: The impact of parasites on gut microbiota of the host is well documented, but the role of the relationship between the parasite and the host in the formation of the microbiota is poorly ...
Different Fish Meal and Fish Oil Dietary Levels in European Sea Bass: Welfare Implications After Acute Confinement Stress
