  • Herring Diversity (Family Clupeidae and Dussumieriidae) in North Carolina
    Herring Diversity (Family Clupeidae and Dussumieriidae) in North Carolina North Carolina is home to 13 species of herrings, but most people only know of or heard of the more common ones such as American Shad, Hickory Shad, Alewife, Blueback Herring, Atlantic Menhaden, Gizzard Shad, and Threadfin Shad (Table 1; NCWRC undated – a). Except for perhaps some fishermen along the coast, few people have ever heard of or seen Round Herring, Yellowfin Menhaden, Atlantic Herring, Scaled Sardine, Atlantic Thread Herring, or Spanish Sardine. Table 1. Species of herrings found in or along the coast of North Carolina.

Fish taxonomists now place this species in the Family Dussumieriidae. Alewife and Blueback Herring are often referred to as “River Herring”; other colorful names applied to this family of fishes include glut herring, bigeye herring, nanny shad, stink shad, or just plain “shad”. Each species has an American Fisheries Society-accepted common name (Page et al. 2013) and a scientific (Latin) name (Table 1; Appendix 1). Herring occur across the state in freshwater and saltwater environments, but especially in many of our reservoirs, coastal rivers, estuaries, and offshore (Tracy et al.

  • History of Striped Bass Management in the Colorado River
    American Fisheries Society Symposium 80:15–23, 2013 © 2013 by the American Fisheries Society History of Striped Bass Management in the Colorado River WAYNE GUSTAVESON* AND GEORG BLOMMER Utah Division of Wildlife Resources Post Office Box 1446, Page, Arizona 86040, USA Abstract.—The discovery of landlocked populations of striped bass Morone saxatilis in Santee–Cooper Reservoir, South Carolina and Kerr Reservoir, Vir- ginia prompted a rush to stock striped bass in other inland waters of the United States, including impoundments in the Colorado River. Fisheries managers re- sponsible for Colorado River waters studied existing literature and predicted that it would be unlikely for successful natural reproduction of striped bass in these systems. Striped bass population development proved unique in the Colorado River system, which is marked by nutrient-poor, well-oxygenated waters with limited forage. Natural reproduction did occur in these reservoirs despite the lack of current previously thought to be essential for successful reproduction, resulting in high survival. Developing populations were sometimes overabundant to the point of forage elimination from pelagic zones. Lack of prey limited growth and temporarily reduced reproduction. Eventually forage returned, increasing striped bass growth and maturity, which led to more reproduction (a “boom and bust” cycle). Planned low-impact, low-abundance adult trophy fisheries produced by managed stocking were replaced by high-abundance juvenile fisheries with high catch rates produced by natural reproduction. In most years, juvenile striped bass living in warm surface waters proved to have the competitive advantage over adults for limited forage.

  • Summary the Sample of Gizzard Shad, Dorosoma Cepedianum (Le
    Summary The sample of gizzard shad, Dorosoma cepedianum (Le Sueur), used for this study consisted of 7, 477 fish from Elephant Butte Lake, New Mexico. They were taken be- tween June 1, 1964, and December 31, 1970. Locality of this study, along with findings in the literature, allows extension of the described range of gizzard shad. Extension of standard descriptions of range of the species includes a broad strip along the western boundary encompassing the Great Plains of Wyoming and Colorado and westward to the Continental Divide in New Mexico and north-central Mexico. Published opinions of the role of gizzard shad in community ecology of fishes vary with characteristics of the waters in which studies have been made. Value of the giz- zard shad as a link in the food chain of game fishes is not disputed, at least when the shad is small. With a high reproductive potential and rapid rate of growth, gizzard shad tend to overpopulate many waters to the detriment of other fish populations. This is true in warm, shallow lakes with mud bottoms, excessive turbidity, and few predators. The gizzard shad is highly esteemed as a forage fish in fluctuating impoundments which contain deep and relatively clear water, have abrupt shorelines, support little or no littoral vegetation, adequate plankton, sparse benthic flora and fauna, and con- tain sufficient predators to crop young-of-the-year shad. This is essentially a descrip- tion of Elephant Butte Lake, except that predation is inadequate to prevent stunting. Age and growth determinations were made from scales by use of the Lee Method (corrected direct-proportion).
