Responsibility
Changes in atmospheric carbon dioxide concentration should have little effect on rising alkalinity concentration in aquaculture systems. Climate change is of greater concern in freshwater aquaculture than is an increase in alkalinity.
Health & Welfare
Iron is the fourth most abundant element in the earth’s crust, but occurs at very low concentrations in surface waters and oceans. It is an essential element for many organisms as part of many enzymes, and also has an important role in plant photosynthesis.
Responsibility
Copper is used for control of the blue-green algae responsible for off-flavors in aquaculture animals, treating diseases and parasites, and avoiding cage net fouling. Although copper is an essential nutrient for plants and animals, an excess can negatively affect the environment and human health.
