The diversification of future aquaculture feed formulas is expected to rise due to the increasing fish feed production. Changes in formulas and the corresponding adjustments to processing parameters can create variations in the pellet physical qualit

Yellowtail kingfish (Seriola lalandi), a marine species, has recently been cultured in recirculation aquaculture systems (RAS). A challenge regarding faecal waste management of farming yellowtail kingfish in RAS is their poor faecal integrity. One ap

This study assessed the potential of four bacterial (Methylococcus capsulatus) single cell protein (SCP) products as alternative protein sources for Pacific white shrimp (Penaeus vannamei) diets. A growth trial and a digestibility trial were undertak

Applying an external carbohydrate source to stimulate heterotrophic bacteria growth in biofloc systems is a common practice which could be simplified by combining the carbohydrate source with the feed into one pellet. In the current study, such an ap

Abstract Sustainable aquafeed production requires fishmeal replacement, leading to an increasing use of plant-derived ingredients. As a consequence, higher levels of antinutritional substances, such as non-starch polysaccharides and phytate, are pres

The first part of this study evaluates the occurrence of mycotoxin patterns in feedstuffs and fish feeds. Results were extrapolated from a large data pool derived from wheat (n = 857), corn (n = 725), soybean meal (n = 139) and fish feed (n = 44) sam

Intensive aquaculture practices involve rearing fish at high densities. In these conditions, fish may be exposed to suboptimal dissolved O2 levels with an increased formation of reactive O2 species (ROS) in tissues. Seaweeds (SW) contain biologically

In aquaculture, fish may be exposed to sub-optimal rearing conditions, which generate a stress response if full adaptation is not displayed. However, our current knowledge of several coexisting factors that may give rise to a stress response is limit
