Abstract
Growth and survival of the benthic feeding fish Leiosrotnus xanrhurus (‘spot”) was compared in man-made (Project Area 2) and natural oligohaline subtributaries of the Pamlico River Estuary. Experiments during 1984 defined a viable protocol for collecting and individually marking fish, and for employing enclosures to assess growth (increase in weight) and survival of the fish. Spot were collected by short (30 second) otter trawls, and individually marked by clipping all or part of specific fins. Growth and survival of spot in man-made and natural areas was compared by holding a predetermined number of fish for two weeks within circular enclosures placed in both areas.
Growth and survival of spot were similar in the Project Area and the natural creeks. These experiments imply that the Project Area is capable of functioning effectively as a nursery area for spot and other benthic predators with similar feeding habits.
