Summary of ACH Solutions
Traditionally, production in Australia has relied on stocking clay ponds with large crayfish breeders for harvest of 5-15 g juveniles that are stocked in growout ponds and reared 9 months to commercial size (70 g). This presents a number of problems:
- Lack of control of reproduction.
- Increase of diseases affecting egg and juvenile survival.
- High levels of juvenile loss due to cannibalism and predation during the extended rearing time.
- Variable age of harvested juveniles, where mixed cohorts in the pond may affect commercial harvest distribution spread, female size and biomass composition.
- Unreliable supply of uniform commercial size crayfish to the market.
- Although there are significant innovations, this production strategy has remained largely unchanged in commercial farms.
ACH Novel Solutions
Among the knowledge-based technology advances, we now:
- Produce significant numbers of high-quality anti-biotic free, specific pathogen free (SPF) juveniles in ponds or hatcheries.
- Apply molecular marker assisted genetic selection programs to improve growth rate, disease resistance and juvenile production.
- Obtain feed conversion rates of around 1 – 1.4: 1.
- Eliminate water exchange and discharges of wastes to the environment.
- Harvest 5-6 tonnes per hectare /140-day cycle, of 60-90 g monosex individuals.
- Deliver consistent product sizes (60-90 g) to the market year-round.
- Significantly increase production through growout modules that are economically viable, environmentally sustainable and socially responsible.
