Nitrogen a limiting factor in aquaculture production
Improved feeds and feeding practices increase the proportion of nitrogen recovered in fish and shrimp and lessen the amount of ammonia excreted by the culture animals.

Biofilter start-up problems? Just add sugar!
One way to jump start biofilter operation is by adding sugar, which can provide sufficient organic carbon to neutralize the ammonia-nitrogen produced.
Responsibility
Microbial mats remove nitrogen, phosphorus from aquaculture effluents
Research has shown that microbial mats are effective at removing nitrogen and phosphorus from aquaculture effluents.

Nitrogen management for shrimp nutrition in low water-exchange production systems
Research in culture systems without water exchange indicates that dietary protein levels have great impact on dissolved inorganic nitrogen loading.
