12.1.1 Importance of cray fish
Cray fish or craw fish are popular freshwater crustaceans in Europe and Australia. Their commercial exploitation and culture are very popular in the above continents due to high demand and consumers' preference. They are being cultured in ponds and marketed. Worldwide cray fishes are the freshwater crustaceans contributing more to the aquaculture production. Procambarus clarkii is the most widely cultured species among the cray fishes and Cherax spp are the next ones. Craw fish are temperate in distribution and can live and grow only in temperatures below 20 deg C. Therefore they are not distributed in tropical countries. Their breeding biology is well known and therefore their seed production is also popular in the countries where they are cultured.
