Abstract:

The invention relates to systems and methods for reducing algal biomass in eutrophic water, wherein organism that feed on algae are introduced into the eutrophic water and cultured in the eutrophic water, until the algal biomass is reduced or the organisms have reach desirable size. The body of eutrophic water can be restocked with juveniles after harvesting. The organisms can be fishes and/or shellfishes. The methods further comprising producing biofuel, specialty chemicals, nutraceuticals, food, and/or fish meal from the harvested fish.

Abstract:

The invention relates to systems and methods for regulating algal biomass in offshore waters near an oil and gas production platform. The systems of the invention encompasses a plurality of modules for managing nutrients, algae, and aquaculture, including enclosures for containing aquatic organisms, and various operating subsystems that are operably associated with surface and underwater structures of the platform. In one embodiment of the invention, aquatic organisms are cultured in eutrophic water to feed on algae, thereby reducing the algal biomass. In other embodiments, the diversity of algae in an algal bloom is modified and the productivity of oligotrophic water is increased.
