Volunteers can assist the scientists, however, by collecting shellfish for analysis in designated study areas. Shellfish are easier to collect than finfish because most tend to move more slowly or not at all. Moreover, they often congregate an oyster bed or a boulder studded with mussels are two examplesand are fairly easy to reach. The training of volunteers should include a session on the identification of the species required for testing. Most of the popular field guides for the coastal regions include sections on shellfish identification.
Volunteers can bring a suitable guide to the site to identify any questionable specimens.
Once at the sample site, volunteers should capture animals using the method designated by the program manager. They may also want to record auxiliary measurements, such as water temperature and site conditions, and visually evaluate the surrounding area. Such information may be helpful if abnormally high levels of toxic substances, coliform bacteria, or the neurotoxin causing PSP are found by the laboratory. The volunteers should carefully label the sample container in which the animal will be transported with the date, site name, shellfish type, and the name of the collector. An indelible marker is best for ensuring that the labeling is permanent.
