Abstract:
... Blood is an important animal by-product and an attractive source for animal feed production. However, the outspread of bovine spongiform encephalopathy led to strict regulations on the usage of animal by-products in animal feed. Although, the ban on certain processed animal proteins has been partially abolished in recent years, it is still challenging to distinguish legal from illegal protein addi ...

Abstract:
... The trend toward using plant‐based ingredients in aquafeeds is set to intensify; however, mycotoxin contamination might be a challenge. Two diets, with deoxynivalenol (DON) levels of 1,166 μg/kg (1.1 DON) and 2,745 μg/kg (2.7 DON), were prepared for short‐term DON exposure (50 days). A third diet with a low DON level of 367 μg/kg (0.3 DON) was prepared for long‐term DON exposure (168 days). Ingest ...

Abstract:
... Photosynthetic microalgae are unicellular plants, many of which are rich in protein, lipids, and bioactives and form an important part of the base of the natural aquatic food chain. Population growth, demand for high-quality protein, and depletion of wild fishstocks are forecast to increase aquacultural fish demand by 37% between 2016 and 2030. This review highlights the role of microalgae and rec ...

Abstract:
... The growing demand for aquaculture products can only be maintained by increasing the production of lower trophic species such as bivalves and tunicates. Low trophic species avoid the energy losses during trophic transfers to build animal protein, making them ideal candidates to exploit available resources in coastal waters. In the particular case of fjords, forced upwelling of deep nutrient-rich w ...

Abstract:
... Glycerol is a well-tolerated additive in aquafeeds. We hypothesized that in seabass, a carnivorous fish whose endogenous carbohydrate demands are mostly met by hepatic amino acid gluconeogenesis, glycerol effectively competes with these substrates for endogenous glucose and glycogen synthesis. To test this hypothesis, we injected fasted and fed juvenile seabass with an intraperitoneal 2 g.kg−1 bol ...
