Aquafeeds
Discussion of aquaculture development should consider trophic levels. Seaweed culture, for example, could possibly double plant food production by farming less than 1 percent of the ocean’s surface.
Responsibility
The regulatory system for aquaculture in New Zealand addresses social and cultural factors through legislation and policies that strongly utilize public consultation. The indigenous Mäori people, for example, play an integral role in aquaculture development.
Responsibility
Carbon dioxide is both a nutrient and a waste product in aquaculture. Some pond managers feel that application of organic matter to provide additional carbon dioxide can reduce pH and control blue-green algae.
Health & Welfare
Aquaculture may deliver commerical quantities of the tiny sea creatures, Bugula neritina, that provide important anticancer compounds.
Health & Welfare
The microbial flora of farmed seafood products, particularly the microorganisms considered human pathogens, are important to individuals and agencies.
