Responsibility
Aquaculture ponds typically have ideal conditions for the growth of various species of phytoplankton. Green algae are considered most desirable in freshwater ponds.
Responsibility
Iron supplementation of pond fertilizers can improve their effectiveness in promoting phytoplankton growth. Ferrous iron in bottom sediment precipitates hydrogen sulfide gas produced by microbial activity.
Responsibility
Phosphorus from uneaten feed and feces of culture animals can cause excessive phytoplankton growth and associated degradation of water quality.
Responsibility
Phytoplankton are essential in intensive aquaculture ponds but an excess can result in shallow thermal stratification.
Responsibility
Copper sulfate is widely used as an algicide in ponds and other aquatic systems. Although copper quickly disappears from pond water, cupric ions can be harmful to aquatic animals.
