about the biology and ecology of most bonefi sh species. This is particularly true of
early life history stages of bonefi sh, including both larval and early juvenile stages.
Early life stages are often of critical importance to fi sh populations. The larval
stage is when dispersal occurs over the greatest distances, connecting populations
that may otherwise be separated by barriers to juvenile or adult movements. Larval
and early juvenile stages are also the ones in which mortality rates are greatest and
can vary considerably in response to a variety of environmental, biological, and
anthropogenic infl uences (Chambers and Trippel, 1997). Physical transport of larvae
by ocean currents, larval behavior, varying environmental conditions that affect
larval growth, trophic interactions that affect larval survival, and both quantitative
and qualitative differences in settlement and nursery habitats can cause larval infl ux
to vary (reviewed by Cowen, 2002; Leis and McCormick, 2002). |
