Use of copper sulfate in fish and shrimp ponds
Copper sulfate is a cost-effective algae control for aquaculture ponds but producers should consider alternative products or management practices.

Factors affecting efficiency of commercial fertilizers in aquaculture
Intensification of pond aquaculture involves the use of commercial fertilizers such as urea and triple superphosphate to stimulate phytoplankton blooms. There is no objective way of determining the ideal fertilization rate for an individual pond.

Phytoplankton in aquaculture ponds: Friend or foe?
A vigorous phytoplankton bloom will support a healthy benthic community and will contribute significantly to stabilising and maintaining adequate pond water and bottom quality.

La correcta circulación del agua en los estanques, Parte 2
El promover la circulación del agua durante el día es una estrategia eficaz para enriquecer el agua del estanque con el oxígeno producido por la fotosíntesis, y puede reducir significativamente los costos de aireación suplementaria en la noche. Muchos tipos de bombas de circulación de agua comerciales eficaces están disponibles.

La correcta circulación del agua en los estanques acuícolas es crítica
Muchos estanques acuícolas requieren aireación mecánica tanto para aumentar los niveles de oxígeno disuelto como para favorecer la mezcla de las aguas ricas y pobres en oxígeno, que también ayuda a prevenir el volteo.

Proper water circulation in aquaculture ponds, Part 2
Promoting water circulation during the day time is an effective strategy to enrich pond water with oxygen produced by photosynthesis, and can significantly reduce the costs of night time supplemental aeration. Many types of effective, commercial water circulators are available.

Erosion, sedimentation in earthen aquaculture ponds
The control of external inputs of suspended soil particles to ponds and internal erosion of embankments and bottoms should begin at the design and construction stage.
