Empirical Model of the Trophic Basis for Fishery Yield in Coastal Waters of the Eastern USA

Autor: W. E. Schaaf, D. S. Peters

Publikováno v: Transactions of the American Fisheries Society. 120:459-473

A synthesis of information describing the trophic basis for production of marine fishery yield along the east coast of the USA from New York through Georgia is presented. It includes a documentation of the species composition and magnitude of fishery

A Simulation Model of How Life History Strategies Mediate Pollution Effects on Fish Populations

Autor: W. E. Schaaf, C. W. Krouse, David S. Peters, D. S. Vaughan, L. Coston-Clements

Publikováno v: Estuaries. 16:697

Pollution effects on fish populations were estimated with a simulation model, using Leslie matrices. Results from changing only first-year survival rate (So) have already been published (Schaaf et al. 1987). This paper explores the effects of perturb

Effects of Fishing on the Atlantic Menhaden Stock: 1955–1969

Autor: W. E. Schaaf, Gene R. Huntsman

Publikováno v: Transactions of the American Fisheries Society. 101:290-297

To determine the effect of purse-seine fishing on the Atlantic menhaden (Brevoortia tyrannus) population, we analyzed data from 1955–69 on fishing activity and catches. Changes in fishing efficiency necessitated establishment of an abstract effort

Fish Population Responses to Chronic and Acute Pollution: The Influence of Life History Strategies

Autor: C. W. Krouse, D. S. Peters, L. Coston-Clements, D. S. Vaughan, W. E. Schaaf

Publikováno v: Estuaries. 10:267

We have developed a simulation model to estimate pollution effects on economically important estuarine-dependent fish populations. Traditionally, pollution studies have focused upon impacts on individual organisms; however, wise management of marine
