Aquaculture, encompassing the cultivation of diverse saltwater and freshwater fish and shellfish species, is rapidly expanding, driven by the pressing need for sustainable food production. However, intensified farming practices often lead to significant economic losses due to fish mortality from infectious diseases and stress‐related conditions. Consequently, enhancing the immune responses of farmed species has become vital fo...

Immunostimulants were widely used in aquafeed due to their multiple important functions, including promoting growth, enhancing non‐specific defence mechanisms and resisting infectious diseases. But the efficiencies of the positive effects of immunostimulants were affected by the duration of the administration and their dose. Short‐term and normal‐dose of immunostimulants promoted the growth and enhance non‐specific immunity of...

Most host organisms undergo metabolic changes in response to pathogens, environmental cues or simply to boost their immunity. Metabolic modulation has therefore been exploited by both host and pathogens to outwit the other during host–pathogen interactions. Recent studies have revealed that a growing number of metabolites and metabolic processes in crustaceans are crucial in host–pathogen interactions. Here, we reviewed recent...

Clostridium butyricum is a bacterium of rod shape, strictly anaerobic, Gram‐positive and form spores. Short‐chain fatty acids, biofuel compounds and precursors of biomaterials (H 2 , butanol and 1,3‐propanediol) are produced by C. butyricum during the fermentation of carbohydrates and sugars. In humans and animals, although C. butyricum has been found to be associated with botulism in infant and necrotising enterocolitis in pr...

The rapid expansion in shrimp farming comes with problems such as inadequate culture technology, disease outbreak, water pollution and other environmental degradation‐related problems. Prominent among these is the level of ammonia, which has been rising steadily in the last couple of years, mainly due to farming practices and other anthropogenic activities, and therefore has had consequent effects on marine life, especially sh...

Gut microbiota is important and plays a crucial role in the host health and nutritional metabolism through multiple mechanisms. Short‐chain fatty acids (SCFAs), which are carboxylic acids with aliphatic tails
