New oyster plant to propel NB into global market

The building of a new aquaculture facility in New Brunswick (NB) could launch the province into the international farmed oyster market.

Village Bay Sea Products will begin construction on a CAD 1 million (USD 981,595) farmed oyster system in Richibucto. The land-based cultivation system will produce a steady, year round supply of oysters for the international market.

"We are absolutely the first in Canada," said Danny King, general manager at Village Bay. "It's a real innovation."

During July and August, or spawning season, oysters experience physiological changes and become un-appetizing for mollusk consumers. Village Bay lost contracts in the past when it was unable to guarantee the quality of its product in the summer, King told, NB Business Journal reports.

"This will allow us to compete at an international level," he affirmed.

Oyster markets in Brussels, Asia and Germany all seek consistency in their supply, King commented.

Although most farmed oyster facilities are in the water, Village Bay’s will be constructed on land. It will span over 5,500 sqmt and include large temperature controlled tanks.

Oysters’ physiological changes are triggered by warmer water, King explained. By controlling environmental conditions, the company hopes to raise better oysters.

Village Bay wants to lower the water temperature and prevent the oysters from spawning, he informed. The company has attempted the experiment on a smaller scale with positive results.

Once water temperature reaches around 20 degrees, oysters change their stored body fat into reproductive organs in preparation for spawning. Although this does not make them poisonous, they become less appealing, explained Marie-Josée Maillet, a biologist with the NB Department of Aquaculture.

Cultivators solve prevent spawning through genetic manipulation, such that the oysters have an extra set of chromosomes, King said.

Cultivators in France use genetic sterilization but have experienced major problems with high death rates. The other downside is that these oysters must be artificially spawned in the lab, he continued.

According to King, the tank method should maintain the mollusks’ fat levels. Then, when the oysters are ready to spawn, they will manipulate the water temperature.

Around 11 million farmed oysters are sold each year in NB, said Maillet. The two main farmed varieties are commercial and cocktail oysters.

Village Bay hopes to finish constructing the exterior of the building this summer and continue the internal construction into autumn.
 
The project recently received CAD 375,000 (USD 368,098) through an innovation grant from Fisheries and Oceans Canada (DFO). The Aquaculture Innovation and Market Access Programme (AIMAP) funding assisted in leveraging an anticipated total of over CAD 1 million (USD 981,595) from other sources.
