Davis GE. 1978. SFRC M-530 Management Recommendations fo Juvenile Spiny Lobsters, Panulirus argus in Biscayne National Monument, Florida. Report M-530. South Florida Natural Resources Center. Homestead, Florida
The distribution, abundance, growth, and migration of spiny lobsters, Panulirus argus, in southern Biscayne Bay, Florida, were investigated from 1975 to 1978, using skin and SCUBA diving techniques and roller frame trawls. Impacts of fishery activities were also documented. The abundance of post-larval to medium-sized juvenile P. argus 8.5 to 60 mm carapace length (CL), caught in bait shrimp trawls was only one third as great in 1976-78 as it was in 1968-69. Most larger juvenile lobsters (50-75 mm CL) in the Bay were concentrated in rocky dens along the western shore of Elliott Key and in the tidal creeks between the Keys. Data on growth and migration were collected from 1,688 observations of 534 of the 5,080 P. argus tagged during the study. Growth rates varied with season and condition of individual lobsters.
