Study evaluates production characteristics, minerals, off-flavors and water quality dynamics on channel catfish reared in used and in new biofloc water.
Responsibility
Fast, easy, reliable method offers great potential for all aquaculture systems There is a widespread need for cultivation-free methods to quantify the viability of microbial communities in aquatic environments. This demand also exists within the aquaculture industry, where rapid and reliable methods for measuring bacterial activity and bioavailable organic matter in water are increasingly required.

Prof. Claude Boyd discusses the importance of pH for farmed fish and shellfish, the normal and natural fluctuations and how aquaculture systems can manage it.
Responsibility
Several large shrimp farms in Latin America, originally built to operate using significant, flow-through water exchange with the surrounding environment, have been retrofitted to a recirculating operation mode. This modification provides numerous benefits, including improved biosecurity.
Responsibility
Confusion can result because of differences in units (dimensions) used to report water quality variables, which can lead to faulty assessments. Professor Claude Boyd discusses issues related to units of measure for some common water quality values in aquaculture.

Wisconsin State Rep. Mary Felzkowski and others are championing aquaculture to grow food production in the state, with a keen interest in recirculating aquaculture systems (RAS).
Health & Welfare
Phytoplankton has several important effects on water quality, including removing ammonia nitrogen from water and absorbing nutrients from the water for its growth. Abundance of blue-green algae tends to increase as nutrient inputs in aquafeeds or fertilizers increase.
