Abstract
Brachyuran larvae were sampled every two hours at two depths in Indian River Inlet over six consecutive tidal cycles. Larvae from seven taxa were collected. Three taxa were identified at the level of species. Pinnixa spp. and Uca spp. zoeae were most common at the surface on ebbing tides and were apparently exported to coastal shelf waters. Uca spp. and Callinectes sapidus megalopae were common near the bottom on flooding tides. This would promote retention in the estuary and is consistent with previous reports in the literature. Ovalipes ocellatus, Cancer irroratus and Libinia spp. were most common on flooding tides. This suggests that a pool of these larvae existed in adjacent coastal waters, and that these larvae were carried into the inlet on flooding tides.
