Ponds

you should Clean the ponds thoroughly before putting the crayfish es into them. Ponds that had been practiced used for more than one year should be sanitized by insolating or disinfecting first ly . Insolating is available for those ponds could be drain ed completely. Those ones can not be drained should be handled by medication such as calces and bleaching powderchloride of lime etc. Good aeration system is essential to keep dissolved oxygen level for normal and fast growing. Especially in the dawn.

Ponds should be drained , drafty and appropriate float glass above it to keep away from snake or mice etc. And there should be bolt netting at the inlet and outlet to prevent crayfishes from running away. It is necessary to distribute different forms of habitat by tyres and netting throughout the ponds as crayfishes are timid animal requiring some form of shelter for faster growth rate, and crayfishes' mouting oftentimes to grow in its lifetime, this leaves them in a safe shell state. Gravel lined natural hides for juvenile crayfishes. Gravel also keeps crayfishes out of the silt which accumulates on the bottom of the pond which make crayfishes cleaner. Excessive sludgy should be removed.

Ponds should not be too deep, 0.7-1.5 meter deep maybe appropriate. This leaves aquatic grass prone to photo-synthesize and make it easy to supplement oxygen.

Water should be fresh and there is enough dissolved oxygen. Keep water PH value as 7.0-8.0. Crayfishes may live under 3℃ to 37℃ and thrive under 20℃ to 35℃. Water temperature should not be below 12℃ when crayfishes are in their moulting stage. Water quality and temperature should be monitored daily. It's important to provide optimum conditions for health and fast growing of crayfishes.

Feed

Crayfishes are mainly fed on prawn feedstuff. Animal feedstuff such as fresh fish, earthworms is also available as well as vegetal feedstuff such as soybeans, wheat etc which has to be processed by heating to eliminate albumen albumin enzyme of anti-trypsin. Food nutrition, water temperature and environment should be paid much attention to when crayfishes are moulting.

Routine work

Observation is made regularly to get an idea of the appetite and activity of crayfishes so as to take reciprocal actions immediately. To douse calcium oxide at 20-30 PPM about one time 10 days to 15 days to improve the water quality for crayfishes' moulting.

Transportation

Living crayfish should be packed with ice to keep body temperature when transporting, and wadding is used for packing firmly in polystyrene boxes. Juvenile crayfishes are transported in minimum water and oxygen filled bags. It should be dispersed and watered as soon as it arrived the destination.

Price

Prices are available on the application and depend depended on the size and quantity required.

To maintain and enhance the quality of breeding stock, we actively select strong crayfishes at each harvest and keep adding selectively broodstock from genetic reliable sources to produce high quality and efficient PL. We also pay much attention to the use of newest technologies in hatchery innovation. With many years of successful breeding and growing, we can define advanced management practice now.
