Distribution and abundance of ichthyoplankton in Florida Bay
Ichthyoplankton was sampled at 14 stations with 60 cm bongo nets fitted with 0.333 mm mesh in basins throughout Florida Bay in 1994-1995. In addition, I compared collections madeusing an epibenthic sled to those made with standard ichthyoplankton bongo nets at four stations during July 1997-November...
