Production and Efficiency Increases from Technology Transfer of New Zealand Double-Back Longline Oyster Grow-Out System

Summary:
Taylor Shellfish Farms Canada ULC has completed a technology transfer project that demonstrates a unique double-back longline farm design. Unique flotation drum designs and moulds from New Zealand make this system superior to previous designs and the company intends to commercialize the technology in Canada. This efficient system, primarily used for Mussel sock culture, was developed in Japan, Chile and New Zealand. Until now it has not been applied at all in North America.   

A specialized production machine was imported from New Zealand and then the unique flotation drums required for the system were produced. By October 2011, the farmsite was seeded with 10,000 oyster tubes, with hundreds more being added every day. With this double-back long line system, production within the existing tenure footprint has been doubled. The visual appearance of floats on the water has also been reduced dramatically.

Taylor Shellfish Farms Canada ULC has received numerous enquiries from other growers in the area about converting their own farms to this system, and the company is working with them on delivery schedules. This project has clearly improved the economic and environmental sustainability of shellfish farming in Canada.
