Sport Fishery Harvest and Effort on Albemarle Sound, North Carolina

A creel census was conducted on Albemarle Sound and its tributaries from February 1, 1977 through January 31, 1980 to estimate the total annual sport fishing pressure and harvest of major sport fish species, particularly striped bass (Morone saxatilis). Total sport fishing effort was in excess of 400,000 party-hours per year, and largemouth bass (Micropterus salmoides), was the species for which the greatest amount of specific effort was exerted. The harvest of striped bass and most other species declined drastically during the study. The relative harvests of the sport and commercial...


Currituck Sound Fish Populations Before And After Infestation By Eurasian Water·milfoil

Data collected from rotenone samples of 3 coves before (1959-65) and after (1977) infestation by Eurasian water-milfoil (Myriophyllum spicatum) were compared to document changes in the fish populations. Using the mean of the 3 areas for comparison, both weight and number per hectare increased after water-milfoil infestation. The average weight per individual decreased from 0.02 kg (1959-65) to 0.008 kg (1977). The species were separated into 7 groups. Six of the groups had higher mean numbers per hectare and all groups had higher mean weights per hectare. Multivariate analyses of variance...
