MI­CROAL­GAE are mi­cro­scopic plant com­po­nents of the nat­u­ral food found in marine and fresh­wa­ter en­vi­ron­ments. These are con­sid­ered one of the most im­por­tant wa­ter or­gan­isms be­cause of their many uses. Var­i­ous species of mi­croal­gae serve as nat­u­ral food for milk­fish, shrimp, tilapia, other fin­fishes, and crus­taceans at dif­fer­ent stages. The cul­ture of mi­croal­gae is usu­ally done in the lab­o­ra­tory and con­tin­u­ously mon­i­tored to en­sure good growth be­fore mass pro­duc­tion. Be­cause the out­door cul­ture of mi­croal­gae is de­pen­dent on sun­light and nor­mal tem­per­a­tures to grow, any changes in light and tem­per­a­ture af­fect their growth pat­tern. Mi­croal­gae cul­ture be­comes dif­fi­cult dur­ing the rainy sea­son; at this time, the lo­cal aqua­cul­ture in­dus­try finds it un­fa­vor­able to main­tain their feed­ing sys­tem. Hence, there is a need to look for some­thing that can be used as an al­ter­na­tive to live mi­croal­gae as feed for fish.
