Development and Validation of a New System for Control of Marine Biofouling on Cultivation Structures for Oysters Raised in Suspension

Summary:
Vienneau Aquaculture has been working for several years to develop a technique for raising oysters in the water column rather than near the water surface. First results, although inconclusive in terms of growth, had highlighted constraints that could cause infestations of marine biofouling on cultivation structures, especially mussels. The company has therefore undertaken to validate a process for treating cultivation structures in hot water, perfecting a scalding process which is multipurpose in the sense that the company can treat its various cultivation structures.

The technique of controlling marine biofouling in a hot water bath is common practise in cupped oyster cultivation in Asia and Europe. Results obtained in this study have allowed a procedure to be established for control of marine fouling. A new machine which is better adapted to the reality of oyster cultivation activities in New Brunswick and a local expertise has been developed.
