This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the age structure, recruitment, and reproduction of two endangered anadromous fish species, Atlantic Sturgeon (Acipenser oxyrinchus) and Shortnose Sturgeon (Acipenser brevirostrum), in the Cooper River in South Carolina. The second marginal pectoral fin ray was evaluated as a new ageing technique, and validated in hatchery-raised Atlantic Sturgeon. There was no significant difference between side sampled (left vs. right pectoral fins) in Atlantic Sturgeon (n = 47, t = 0.000, p = 1.00) and Shortnose Sturgeon (n = 48, t = 1.1985, p = 0.2367). Shortnose Sturgeon sampled were estimated to be between 13 to 41 yrs old (N = 39) and Atlantic Sturgeon sampled were estimated to be between 3 to 21 yrs old (N = 9). Reproductive surveys resulted in one Shortnose Sturgeon egg collected in 2015 and 14 eggs collected in 2017. No Atlantic Sturgeon eggs were collected, but spawning adults were sampled at the spawning site in the Cooper River.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the research was to determine if shortnose sturgeon, Acipenser brevirostrum, occur within the Neuse River, North Carolina. Shortnose sturgeon historically occurred in most major Atlantic Coast rivers from Saint Johns River, New Brunswick, Canada to St. Johns River, Florida. Anecdotal evidence suggests that a population of shortnose sturgeon once occurred in the Neuse River, North Carolina, but their current status was unknown. In compliance with the National Marine Fisheries Service shortnose sturgeon sampling protocol, a two-year intensive gillnet survey was conducted in order to determine the population status of shortnose sturgeon within the Neuse River. Habitat surveys showed that the lower Neuse River, where shortnose sturgeon would be expected to occur during summer, was severely hypoxic in June - September of 2001 - 2002. No shortnose sturgeon were observed during the two-year survey (> 200 h of netting effort) although four juvenile Atlantic sturgeon were encountered. These two species occupy similar habitats in other river systems. A juvenile Atlantic sturgeon tagged with a transmitter moved upstream of the unsuitable habitat and remained in a restricted area until late fall, when water quality improved due to increased flows and lower temperatures. The probability of detection for varying population sizes of shortnose sturgeon was calculated in order to determine if adequate sampling had been completed to conclude an absence of shortnose sturgeon in the Neuse River. The detection analysis stated that a population size of 50 or more individuals should be detected in 200 h of netting effort. Therefore, based on our sampling efforts, we hypothesize that shortnose sturgeon are extirpated from the Neuse River. We believe that poor water quality is a key factor in the extirpation of shortnose sturgeon in the Neuse River. Population recovery may be impossible until habitat quality can be improved. Finally, we observed that shortnose sturgeon have a.

This book was released on 2018 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endangered Atlantic (Acipenser oxyrinchus oxyrinchus) and Shortnose Sturgeons (A. brevirostrum) were once abundant within major rivers along North America's Atlantic coast from the St. John River, Canada and the St. Johns River, Florida. Anthropogenic factors such as over-harvest and habitat degradation have contributed to severe declines in populations of both species throughout their ranges. Despite both species being listed as endangered, significant gaps in scientific literature, particularly population demographics are still present. The objectives of this study are to quantify annual recruitment of juvenile Atlantic and Shortnose Sturgeons in the Savannah River, and to determine environmental drivers of recruitment. The results of this study provide baseline abundance data that will be critical in evaluating long-term population trends and for assessing the effects of dredging in the Savannah River. This study provides key information regarding long-term management of endangered Atlantic and Shortnose Sturgeon throughout the southern reaches of their range.
