He continued "The new hatchery in Singapore will go a long way to providing a stable and high-quality supply of craylings to supply the domestic and potentially international industry, like any aquaculture industry, success often depends on having access to juveniles."
#CLAWFISH FARM HOW TO#
"One of the bottlenecks in the past has been the lack of knowledge on how to extract the craylings from the parents to prevent filial cannibalism." Commented Tan.
Professor Matthew Tan, co-chair for Sustainable Development in Agriculture and Fishery Sectors at Asia-Pacific Economic Cooperation (APEC), said this breakthrough technology was a big win for the industry. That way, we can literally do three grow outs a year instead of only once every 12 months." "For small crawfish farms like ours, we will require professional hatcheries to provide us with craylings, so we can focus on the “grow out” phase. Through this process, the mortality of the craylings spikes, due to various reasons such as environmental changes, mishandling etc.".Ĭrawfish farmer Alex Low, from Johor, said the collaboration with hatcheries like this one would be critical to the industry's growth.
#CLAWFISH FARM MANUAL#
The males and females were randomly put in ponds with the hopes they will produce offspring and then much manual labor is required to separate and collect the fries. "The major problem in the past was that production of craylings was an ad hoc affair.
"We've actually been able to extract the craylings from their parents efficiently and at the same time cut the labor by 90%, which is extremely efficient when you are looking at a commercial scale," Chow said. The company’s founder, Desmond Chow, said the industry's traditional grow out farmers (grow out farming is the post-hatchery rearing process from fry to market size crawfish) had been hampered in the past by inefficient on-farm breeding processes that suffered large production losses. This auto separation system is versatile and could also be used for certain breeds of fish and shrimp. This technology could change the face of global aquaculture.Īmong the techniques and technologies developed to improve crawfish production is an auto separation system for crawfish, that has the ability to produce hundreds of thousands of juveniles each day.
Now, a Singapore-based company is in the process of patenting technology and building a specific pathogen free (SPF) hatchery to increase the number of crawfish fry produced and lower their hatching mortality.
