Algae alternatives serve in larval rearing of sea bream
Sea bream fry are produced using the greenwater technique in which microalgae are added to larval-rearing tanks during the first 20 to 30 days after hatching.
Responsibility
HISTAR development
The Hydraulically Integrated Serial Turbidostat Algal Reactor (HISTAR) developed at Louisiana State University superimposes contaminant control techniques on a continuous algal production system.

Phytoplankton in aquaculture ponds
Aquaculture ponds typically have ideal conditions for the growth of various species of phytoplankton. Green algae are considered most desirable in freshwater ponds.

Shrimp feed trials find pen size matters
By comparing the growth of shrimp fed different diets in big versus small net pens, trial results suggested that shrimp could compensate for lower diet quality by grazing on the algae growing on the surfaces of the net cages.
Responsibility
Phytoplankton dynamics in aquaculture ponds
Phytoplankton are essential in intensive aquaculture ponds but an excess can result in shallow thermal stratification.

Formulated diets for bivalve spat replace algae in hatchery trials
Although the hatchery rearing of bivalves currently relies heavily on the mass production of microalgae, new feed alternatives are being developed.
