References ... 143Atlantic tarpon (Megalops atlanticus) represent a valuable component of the recreational shery across a distribution that encompasses coastal and nearshore waters
of the Caribbean Sea, Gulf of Mexico, and the western Atlantic from Canada toBrazil. Peripheral populations occur in the eastern Atlantic off Africa and the Paci c
of Panama. Tolerant of wide ranges in salinity and oxygen concentrations, tarpon
distribution is limited by sensitivity to low temperature at the northern extreme of
the range (Zale and Merri eld, 1989). The reproductive cycle of tarpon is complex.
Adults spawn offshore (Crabtree et al., 1992), eggs and larvae have an extended
planktonic stage followed by recruitment into fresh and brackish water nursery
areas, and juveniles spend 4-5 years in rivers, bays, and estuaries before joining
offshore aggregations of adults (Crabtree et al., 1995). Adults in some portions of
the range are highly migratory. They move from spawning sites to forage areas on a
seasonal basis (see Luo et al., Chapter 18, this volume). |
