Accessing Hurricane-Produced Mudflat BSC
Mudflats (open water in background) derived via erosion and habitat conversion from former mangrove forests often have a band of mangroves adjacent to the creek bank. Here a researcher accesses a mudflat at high tide to make measurements....
Awaiting High Tide to Set Block Nets
Sampling fish within the intertidal zone of a mangrove forest requires setting a block net at the interface between forest and river at high tide, then retrieving the net at low tide. Here researchers await high tide to set the nets seen in the boat. ...
Deploying Lift Net, Everglades National Park
Lift nets buried in the forest floor and deployed at high tide permit the estimation of fish density within flooded forests....
Closing Seine Around Pivot Pole, Everglades National Park
Seining for fish in open water necessitates closing the seine quickly to avoid fish escape. Closing the seine around a pole offshore accomplishes this objective in sampling....
GCC BSC Set Block Net
Setting block net across an intertidal rivulet draining a hurricane-derived mudflat. Net is retrieved at low tide to obtain an estimate of fish catch. Fish density was found to be greater in waters draining natural tidal forests than in waters from mudflats formed as a result of landfall of a Cate...
