This one-year project involved several components, and aimed to develop and evaluate equipment designed to mitigate the impact of solitary or colonial species of tunicates present on the mussel farms of the co-applicants. The original objectives of the project were to develop equipment for treating colonial tunicates and a platform for the treatment of various species of tunicates. The ultimate goal of the project was to improve existing treatment equipment for pre-commercialization purposes. The overall objectives of the project have been achieved. With AIMAP funding, the project has developed two innovative colonial tunicate treatment systems using treatment technologies in and out of the water. A high pressure sprayer already in use was improved using an innovative and safer nozzle configuration. A device for housing equipment was developed for mussel farmers who need to treat various species of tunicates present on their farms. It should be noted that in the past, mussel farmers used a garden hose to dislodge tunicates from mussel lines. This mitigation method was not only time consuming, but also produced inconsistent results in treating lines, because its effectiveness depended on the distance from the sprayer to the line. Manual mitigation methods are a challenge when large crops of mussels are involved. While the performance of lines decreases, labour costs and processing times gradually increase depending on the degree and evolution of the infection during the season. By operating this high pressure sprayer, it is hoped that mussel farmers will be able to treat their entire crop within a week instead of over the previous three-to-four-week period. With this mechanized system, mussel farmers hope to improve safety on board their vessels, since workers will no longer have to lean over the side to treat lines.

The provision of supporting and standardized drawings for each of its treatment systems will enable this project to provide mussel farmers with a basis for building their own new systems. These drawings will enable farmers to develop new ideas and systems, and to communicate their needs to equipment manufacturers.
