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. 

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. 

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). 

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. 

Shrimp nursery systems offer the shrimp industry an important opportunity to increase profits, by helping produce strong, healthy and uniform juveniles with significant potential for compensatory growth after their transfer for final pond grow-out. Biofloc technology and water quality are 

It is one of the most commonly measured water quality variables in aquaculture, and probably the most misunderstood water quality variable in aquaculture. The pH levels in water have a propensity to change rapidly, but this is a natural phenomenon 

Attention to pH, a numeric scale used to specify the acid or alkaline condition of an aqueous solution, is very important. Reducing biomass and feeding rates together with phytoplankton control and liming can often keep pH at desirable values. 

Amigos, colegas y ex alumnos del Profesor Claude E. Boyd, Ph.D. de muchos años de la Universidad de Auburn, no esperan que el nativo de Mississippi vaya a reducir su paso, a pesar del callado anuncio de su retiro a 

Friends, colleagues and former students of longtime Auburn University Professor Claude E. Boyd, Ph.D., don’t expect the Mississippi native to slow down, despite the quiet announcement of his retirement earlier this month. The 50-year veteran researcher’s career has been truly
