What can plankton be used for?
Plankton is the productive base of both marine and freshwater ecosystems, providing food for larger animals and indirectly for humans, whose fisheries depend upon plankton. As a human resource, plankton has only begun to be developed and exploited, in view of its high biological productivity and wide extent.
Is plankton considered fish?
Plankton are microscopic organisms that play an important role in the marine ecosystem. They are food for shelled animals and fish. Plankton refers to both plant- and animal-like beings that float along the sea’s tides and currents.
How do you grow plankton for fish?
To grow phytoplankton, you need to provide a starter culture with light, nutrients, carbon dioxide, oxygen, and a clean place to live. About every 7 days, you harvest about half to two-thirds of the culture to feed your rotifers, brine shrimp or corals, and you repeat the process over and over again.
