Description:

The growing popularity of the aquarium trade is greatly increasing the demand for many ornamental fish. While shipping technology has made the worldwide transportation of ornamental fish possible, a significant portion of the fish caught for the aquarium trade perish in transport before being sold to hobbyists. One of the major causes of fish death in transport is ammonia building up to toxic levels in the shipping bags. In order to solve this problem, we investigated the effectiveness of using nitrifying consortia in reducing the ammonia build-up in marine fish bags during transport. A pre-activated nitrifying consortium was effective in safely maintaining low ammonia levels during a three-day experiment. We found that both ammonium chloride and urea can activate nitrifying consortia. Activation of nitrifiers by urea is not only novel but also beneficial due to being less harmful to fish in comparison with ammonia. We also discovered that unexpectedly one nitrifying consortium examined mainly contained ammonia-oxidizing archaea. The confirmation of the concept of the use of activated nitrifying consortia and the usefulness of nitrifying archaea for fish transportation may be beneficial for the fish trading and aquaculture.
