Shipwrecks off NC coast harbor tropical migrants

Shipwrecks and sunken structures off the North Carolina coast may act as stepping stones for tropical fish searching for favorable habitats at or beyond the edge of their normal geographic range. A study co-led by Duke University scientists finds these fishes prefer artificial reefs over natural ones and suggests linked networks of these human-made structures could be used to aid the survival of the ecologically and economically important species.
