Water Parameter for Crayfish / Crawfish

Crayfish can be farmed in large freshwater ponds, a practice known as aquaculture, for food. The most commonly farmed species are Red Claw Crayfish (Cherax Quadricarinatus) in Southeast Asia and Australia and Red Crayfish (Procambarus clarkii) in America. Aquaculture fields typically are shallow ponds sometimes filled with swamp weeds and grass. The substrate of the pond is mud, preferably with a high clay content to prevent water from draining away.

Research has shown that red claw are most active in the evening between 6 p.m. and midnight. This should be the best time for daily feeding since the animals are actively foraging during this period. Broodstock nutrition is

Red Claw / Females

Red claw generally reach sexual maturity by the age of 6 to 12 months at which time they range from 2 to 3 ounces in weight. Mature male red claw develop a distinctive red or orange patch on the outside margin of the claws. Individuals of this same size without the reddish claw patch are usually females. The sexes are best identified, however, by examination of the genital openings on the underside of the cephalothorax at the base of the walking legs. Females have a pair of genital pores at the base of the third pair (counting from the head) of walking legs. Males have a pair of small genital papillae (small projections) at the base of the fifth pair of walking legs.

Crayfish Race / Yabby Race / Yabbies Race

Spirits were high as was the bidding at Australia's richest yabbie races on the Western Downs in Queensland over the weekend.

The event saw fashion, fun and frivolity, with some revellers declaring that it could easily have been Melbourne rather than Moonie.

Moonie's third annual yabbie races attracted around 300 people who watched 64 crustaceans compete in eight races.

White Spot Syndrome Virus (WSSV) has been confirmed in Crawfish / Crayfish

Facts on White Spot Syndrome Virus (WSSV)

By LSU AgCenter. White Spot Syndrome Virus (WSSV) has been confirmed for the first time in Louisiana in crawfish / crayfish from a pond in St. Martin Parish.

This crawfish disease seems to affect mostly the medium to large crawfish / crayfish. Symptoms include sluggish crawfish that don’t move much once they are dumped from the trap. They do not pinch hard and can’t walk. There are no color differences or obvious signs other than weakness and slowness. Some dead crawfish are noticeable in the traps while others are noticeable in the shallow water along the edge of the pond.

Growth and Survival Rate of Crayfish / Crawfish / crawdads

This research was held on October 20th – desember 20th 2006, in laboratory Indoor Fishery, Animal Husbandry and Fishery University of Muhammadiyah Malang. The purpose of this reaserch is to know the growth and survival rate crayfish / crawfish (Cherax quadricarinatus) in which expansion on extreme density unit difference spreading and to know is how much is giving and growth of survival rate best of freshwater crayfish (Cherax quadricarinatus) in extreme density unit.
