Species of Feces Help Phytoplankton Feed Itself

Phytoplankton Culture for Aquaculture Feed

freshwater microalgae and other plant-like organisms. They are used in the production of pharmaceuticals, diet supplements, pigments, and biofuels, and also used as feeds in aquaculture. Phytoplankton are cultured to feed bivalve molluscs (all life stages), the early larval stages of crustaceans, and the zooplankton (e.g., rotifers, copepods) that are used as live food in fish hatcheries.

Can sub-Saharan Africa feed itself?

Although global food demand is expected to increase 60% by 2050 compared with 2005/2007, the rise will be much greater in sub-Saharan Africa (SSA). Indeed, SSA is the region at greatest food security risk because by 2050 its population will increase 2.5-fold and demand for cereals approximately triple, whereas current levels of cereal consumption already depend on substantial imports. At issue ...

Seeking sailors to help measure phytoplankton populations.

Richard Kirby, a plankton biologist at Plymouth University’s Marine Institute, United Kingdom, has observed that phytoplankton—microscopic organisms dependent on photosynthesis—are being affected by rising sea temperatures. Responding to research indicating a dramatic decline in phytoplankton populations, Kirby says, “Phytoplankton underpin the marine food chain; without them the seas would be ...
