Aquafeeds

Microalgae provide food, feed, fuel

About 30 percent of global microalgae production goes to animal feeds, with large applications in aquaculture, particularly for larval stages.

Off-flavors in aquaculture products, part 2

Off-flavors in seafood can stem from a variety of sources. Industrial effluents can at least secondarily contribute to off-flavors in fish. Off-flavor oxidative carbonyl compounds increase during cold storage of some farmed fish.

Farming algal fuel: Economics challenge process potential

Algae offer advantages over terrestrial plants for biofuel production: short generation cycles and fast population growth. Algal fuel production would spare corn and soybeans for consumption as food for humans.

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.
