The use of acidifiers in tropical and non-tropical fish and shrimp culture
The promotion of environmentally sound practices in all fields of fish and shrimp production is a relevant point for the aquaculture industry if sustainability is to be achieved. However, in the field of aquaculture it is well established so far that the inclusion of antibiotics into the diets of fish can promote growth and feed conversion.
But the use of low levels of these antibiotics in animal feeds possesses the possibility to transfer bacterial immunity to species pathogenic in animals and humans. Due to the above mentioned facts alternatives needed to be found.
Since the use of fish silage from preserved fish and fish viscera included the acid preservation, in-feed acidifier came into scientific observation too. Investigate the effects of these short-chain acids onto the fish directly became a point of interest.
The article discusses the effects of organic acids such as sodium lactate on Arctic charr and Atlantic salm, tilapia, trout and shrimp.
The later part of the article discusses how potassium-diformate affects weight gains in tilapia and the various studies conducted to find out the effects of acidifiers on different fish species.
