Fish Group use B-shaped traps


The set up: The traps sit with the opening facing the incoming tide. Two plastic mesh wings are secured at the opening of the traps to direct fish into them. The traps fish for two hours during incoming tide.

The opening is somewhat small so the main fish collected are small fish and shrimp. Fiddler crabs and hermit crabs are also found inside the trap a lot, for the purpose of our study these are not identified and processed. The amount of fish collected using this method is not nearly as much as the data we collect while seining.

Both times while using the these traps we were able to see the wake energy approaching the shore. Some wakes were strong and damaged wings, moved traps or turned them. The wakes this shore is hit by is a constant problem and we have been able to see what recreational boating does to some of our shorelines.
