Shrimp seed production and searanching- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

The pioneering efforts of Hudinaga (1942), in the successful spawning of Penaeus japonicus and rearing of its \nlarvae up to the juvenile stage under controlled conditions, have paved way for the large scale hatchery seed \nproduction of penaeid prawns for aquaculture. There are two basic hatchery seed techniques for mass production of \nlarvae of penaeid prawns are Japanese technique and Galveston Technique. These techniques have been appropriately \nmodified to suit to the different geographical and climatic conditions as well as for different species. Sometimes \ncombinations of these two techniques have also been used.
