Abstract
During
the last few decades, aquaculture as a useful animal protein providing sector
intensifies to meet the growing world population demands. Although fish culture
technological advancement has resulted in increased production, intensive
technology has negatively affected the environment—consequently, aquaculture
research efforts have been diverted towards developing sustainable culture
technology. Introducing algae and bacteria singly or in combination in
aquaculture was advantageous both by ex-vivo and in-vivo culture techniques.
Utilization of microbial consortium in aquaculture can help to construct
three pillars (social, economical, and ecological) of sustainability by
improving water quality, reducing dependency on a wild fish stock as a feed
ingredient, improving the health status of animals, and increasing economic
returns along with protection of the environment. Numerous fruitful research
outcomes on using algal-bacterial systems are available for its application
in aquaculture. In this context, the present article highlights an updated
review of current research trends on various aspects such as application of
algal-bacterial consortia for aquaculture, available technologies based on
their interaction, and recommendations for further improvement. This review
will also provide some critical clues for the standardization of novel fish
culture techniques based on microbial interaction.
