Les personnes impliquées dans le projet:

Samples were made by SCUBA diving and also by installing recruitment granite plates in three harbors monitored along the state's coast.

Description des étapes de la méthode:

1. Recruitment granite plates were installed in three harbors across the Santa Catarina coast. There were five metal sets per locality, each with three 25 x 30 cm square granite plates attached, hung directly into the water by steel ropes so that during low tide they would still be at a minimum of 2 m underwater. During each monitoring event, the metal sets were lifted and placed in a container with seawater from the site, as photoquadrats were taken and further observations were made, with few collections and minimal alterations to the biota on the plates. Afterwards, plates were hung back into the water until the next monitoring event. SCUBA dives were also held across the state’s rocky shores. These dives were performed regularly, often more than once a month, and included not only the assessment of exotic and invasive species, but also the study of the benthic community and environmental variables monitored by data loggers. Five specimens from the São Francisco do Sul harbor were collected and analyzed under a stereomicroscope for identification. Posteriorly, these were fixed in 100% ethanol.
