Polychaete serves as aquafeed for most aquaculture species and as bioremediation agent of organic waste. Polychaete used for broodstocks of finfish and crustaceans stimulates gonadal maturation and endocrine system in penaeid shrimp, therefore overcoming the shortfall in juvenile production of animals and securing reliable production of aquaculture harvests. Commercial feed has gained the most ground in polychaete farming. Microalgae’s essential nutrients and favorable morphology are ideal for polychaete larviculture. Home-made feed is less attractive due to its complex structural fibre but applicable as co-feed in polychaete nourishment. High organic matter waste is competitive as polychaete feed although it might lack adequate nutrients. The ideal feeds for polychaete growth, distinguished by the different life stages, are poorly studied. This review studies the fitness of microalgae in larviculture, nutritional value of commercial feed, and home-made feed as co-feed option, in polychaete nourishment; and the bioremediation benefit from polychaete’s waste-feeding behaviour.
