The green scum shown in this image is the algae bloom in Lake Erie. Within aquatic ecosystems, algae assumes a pivotal role by utilizing photosynthesis to transform water and carbon dioxide into sugar, concurrently releasing oxygen as a by-product. However, inadequate management can create significant environmental consequences.
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
Adding urea to the ocean can cause phytoplankton blooms that serve as a food source for zooplankton and in turn feed for fish. This may increase fish catches. [54] However, if cyanobacteria and dinoflagellates dominate phytoplankton assemblages that are considered poor quality food for fish then the increase in fish quantity may not be large. [55]
Ocean iron fertilization is an example of a geoengineering technique that involves intentional introduction of iron-rich deposits into oceans, and is aimed to enhance biological productivity of organisms in ocean waters in order to increase carbon dioxide (CO 2) uptake from the atmosphere, possibly resulting in mitigating its global warming effects.
Algae grown in floating farms could be harvested and used for food or fuel. All biological life is made up of lipids, carbohydrates, amino acids, and nucleic acids. Whole algae could be turned into animal feed, fertilizer, or bio-char. Separating the lipids from the algae could also create bio-diesel from the lipid content and bio-char from the ...
Scientists in attendance were interested in how harvesting algae could become a method to maintain and improve water quality. Algae to fertilizer: Harvester could help defend against Florida's ...
In oligotrophic water, nitrogen (N) is a limiting nutrient for phytoplankton growth. [17] Nitrate (NO − 3) and ammonium (NH + 4), both inorganic form of nitrogen, are most often taken up by phytoplankton and are necessary for growth and metabolic processes. [3]
Fresh water also has a positive effect on the growth of phytoplankton, since it is less dense, creates a layered water column and carries nutrients necessary for phytoplankton to carry out processes (photosynthesis). Collapse can be caused by nutrient depletion, vertical mixing when nutrients are at the bottom, resulting in less bloom.
