  Microbial activity assessment based on hydrogen peroxide decomposition rates

  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

  Retrofitting shrimp farms to recirculating systems

  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.

  Understanding water quality variables for aquaculture

  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.

  Phytoplankton and its impact on water quality

  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.

  Building a better shrimp nursery, part 2

  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

  The inevitable pH fluctuations of aquaculture pond water

  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

  The oft-overlooked water quality parameter: pH

  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.
