INFERRING TRANSPORT OF ATLANTIC CROAKER (MICROPOGONIAS UNDULATUS) AND SPOT (LEIOSTOMUS XANTHURUS) LARVAE FROM THEIR DEMOGRAPHIC CHARACTERISTICS
Atlantic croaker (Micropogonias undulatus) and spot (Leiostomus xanthurus) spawn in the fall and winter in the shelf waters of the Middle Atlantic and South Atlantic Bights. To settle in their estuarine nursery grounds, they must be transported inshore within a month or two of their births. For these two species, spawning and estuarine ingress may last up to seven months. This seven-month duration of larval ingress means that I can examine ingress with respect to various transport hypotheses. I use data on abundance, birth dates, age, and growth of larvae sampled at the mouths of Oregon and Ocracoke Inlets to examine a generalized model constructed for another estuarine-dependent species, Atlantic menhaden, that spawns during the same time. Whatever model is used, it must explain the transport of these other two species, Atlantic croaker and spot, as well as Atlantic menhaden.
