Global Aquaculture Alliance — The Advocate
A global survey of feed producers in 134 countries found that aquaculture feed production rose 17 percent in 2012, affirming its position as the fastest-growing species sector.
About 30 percent of global microalgae production goes to animal feeds, with large applications in aquaculture, particularly for larval stages.
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.
Pond pH had a strong effect on the effectiveness of a product applied to remove excess phosphate to control algal blooms in eutrophic aquaculture ponds.
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.
Ultrasound offers a low-impact alternative to chemical treatments for unwanted algae, like chlorophyll a, and biofilms in aquaculture.
The Hydraulically Integrated Serial Turbidostat Algal Reactor (HISTAR) developed at Louisiana State University superimposes contaminant control techniques on a continuous algal production system.
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.
Aquaculture ponds typically have ideal conditions for the growth of various species of phytoplankton. Green algae are considered most desirable in freshwater ponds.
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.
