Organisms include all plants (phytoplankton) and animal (zooplankton) live grazed/eaten upon by economically important fishes. PLANT – Unicellular, colonial, or filamentous forms ANIMAL - phytoplankton zooplankton Animal, small protozoans or metazoans such as Microalgae that live in surface water crustaceans and other animals Photosynthetic which is the primer Consumers of the planktonic world producers of the planktonic world Grazed by zooplankton & other aquatic Feed on plankton to obtain energy and nutrients organisms to survive Invisible to the unaided eyes and can only be Mostly are large enough to be seen with naked seen as green patches in large number eyes Include organisms such as diatoms dinoflagellates, & cyanobacteria Found floating in the middle layer of water bodies DYQ 20263: LIVE FEED CULTURE  Chlorella Nannochloropsis Skeletonema PHYTOPLANKTON Dunaliella Chaetoceros Scenedesmus Arthrospira Closterium DYQ 20263: LIVE FEED CULTURE Isochrysis Navicula Spirogyra PHYTOPLANKTON Oscillatoria Westella Anabaena DYQ 20263: LIVE FEED CULTURE Rotifer Daphnia Bloodworm ZOOPLANKTON Moina Tubifex Copepod Artemia sp.
