Abstract:
The past two decades have seen great intensification of the aquaculture industry. Currently
aquaculture production accounts close to 50% of the consumption of fish worldwide. This
substantial growth in the aquaculture sector is greatly attributed by the increase in fish demand,
declining fisheries, improved technologies among others. To meet this demand, there have
emerged intensive culture practices which are associated with both an uncontrolled use of feed
and a massive production of waste. For this reason, the aquaculture industry is currently
considered to produce an adverse and negative impact in the environment. Most governments
have establishmentstrict regulations dealing with the discharge of untreated aquaculture wastes
to the environment. Given the risks associated to the use of antibiotics in general and in fish
farms in particular, bioremediation therefore remains the most health and efficient way of
treating aquaculture waste. Several studies have identified microorganisms as the paramount
bioremediators, as they are able to completely remove the wastes generated by the fish-farm
facilities. This paper reviews several concepts under which micro-organisms bioremediate
aquaculture wastes.
