|a Stone crabs (Menippe mercenaria) were trapped on a lunar cycle (full moon)
from June 1979 to June 1980 to investigate the population biology and life
history of the organism in south Florida marine waters managed by the
National Park Service. Seventeen stations, located throughout the coastal
regions of Everglades National Park and Biscayne National Park, were
fished for an entire year. Five additional stations were fished the last
nine months of the study. An array of morphometric and biological data
was taken on each crab captured. Salinity, temperature, water clarity,
principal fouling biota, and bottom type were recorded at each station
during sampling.
Relative abundance, proportion of females, and number of juveniles were
highest in Everglades National Park marine waters from Lostmans River
northward. Also, mean size of both sexes was generally smallest in that
region. Progressing southward along the Gulf of Mexico and east into
Florida Bay, relative abundance of both adults and juveniles decreased,
proportion of males increased, and mean size of both sexes became larger.
Juveniles were never found at most stations sampled in Florida Bay.
Biscayne National Park resembled Florida Bay in number and size of adults,
proportion of males, and lack of juveniles. Juvenile distribution and
abundance was directly correlated with relative abundance of adults and
proportion of females in the trapped population. The primary source of
adults in Florida Bay appears to be a very slow movement of crabs from the
Gulf of Mexico progressively farther into Florida Bay. The stone crab
population in Biscayne National Park may be dispersing from farther north
along the Atlantic coast of Florida. |
