How to Achieve Good Water Quality Management in Aquaculture

Water quality is the most important factor affecting fish health and performance in aquaculture production systems

Environment

Manage pH Cycles To Maintain Animal Health

pH levels in ponds are affected by such factors as time of day, vegetation and aeration activity.

Total Alkalinity, Total Hardness

Proper management of phytoplankton in aquaculture ponds is important to maintain adequate water pH levels.

Measuring Dissolved Oxygen Concentration in Aquaculture

Dissolved oxygen concentration (DO) is considered the most impor-tant water quality variable in fish culture. In the broadest sense, how-ever, dissolved oxygen

Dissolved Oxygen Management In Aquaculture

Regular monitoring can identify changing D.O. levels and avoid stressful impacts on culture animals.

Feeding Affects Pond Water Quality

Since not all feed is consumed by the animals in aquaculture systems, careful feed application is called for.

Measuring Circulation, Mixing in Ponds

Several methods for evaluating water circulation and mixing in aquaculture ponds are available to farm operators.

Feed Efficiency Indicators for Responsible Aquaculture

Environmentally responsible, profitable aquaculture has its foundation in efficient resource use. Feed usually is the most costly item in aquaculture production

Lake, Reservoir Characteristics Affect Cage Culture Potential

Factors that include area, volume and flushing rates interact to affect water quality in lakes and reservoirs.

Dissolved-Oxygen Requirements In Aquatic Animal Respiration

In aquatic animals, blood hemo-globin unloads oxygen to the tissue fluids. Coldwater species have higher dissolved-oxygen concentration requirements

Drying, Liming, Other Treatments Disinfect Pond Bottoms

Drying pond bottoms between cycles is the first step toward disinfection. Puddles and wet areas should receive lime or another effective treatment to eliminate

Embodied Resource Use In Feed-Based Aquaculture

In life cycle analysis of aquaculture, there is a danger of the entire array of embodied resources and impacts being assigned to the production facility
