What?s wrong with current redclaw crayfish stocking practices?

Known Inefficiencies with Current Stocking Practices

  • Stocking numbers are dependent on the numbers of berried females, which makes it difficult to predict stocking numbers.
    Current stocking practices are not conducive to control of genetics, which leads to inbreeding issues.
  • There’s neither control nor accurate information on stocking density, size variations or survival rates, which respectively and cumulatively lead to unpredictable production outcomes.
  • Stocking and harvesting are labour intensive and season dependent—because berried females are required to stock new ponds, not to mention that spawning is season dependent.
  • Stocking and harvesting of ponds are linked—ponds must be harvested to stock new ponds, making stocking quite complicated an exercise.
  • Production outcomes are unpredictable—as accurate stocking density is unknown.

The ACH Solution

ACH offer a simplified method of stocking and harvesting ponds by providing a “batch-in, batch-out’ method. Farmers simply add a specific number of same age ACH craylings to new ponds without the need for harvesting a pond and sorting harvested animals. That also means that there is no need for additional ponds to hold juveniles or broodstock, which in turns allows farmers to utilize all ponds for production.

Further Benefits

  • By using ACH craylings and the ‘batch-in, batch-out’ method, inbreeding is absent resulting in stronger, faster growing animals.
  • Reduced size variation at harvest, reducing labour costs and time.
  • Stocking and harvesting of ponds are not linked and can be undertaken at any time.
  • Farmers can accurately predict and monitor production outcomes increasing productivity and profitability.

Low labour requirement—Batch-in, batch-out method. No need to sort animals into groups for re-stocking.

  • ACH produces healthy, specific pathogen and antibiotics-free craylings from selectively bred broodstock, that eliminate inbreeding issues altogether.
