Hatchery Production of Shrimp Seeds

T he pioneering efforts of Hudinaga in the successful spawning of Penaeus japonicus under \ncontrolled conditions and their subsequent rearing upto the juvenile stage have paved way for the \nlarge scale hatchery production of seed of penaeid prawns for aquaculture. There are two basic \nhatchery techniques for mass rearing of larvae of penaeid prawns - Japanese techniques and \nGalveston technique. These techniques have been appropriately modified to suit different \ngeographical and climatic conditions and different species of prawns used for aquaculture. Thus \nm any gradations between these two techniques have been noticed in different parts of the world. \nSom etim es combinations o f these two techniques have also been used.
