Life history and evolutionary adaptation of Pacific salmon and its application in management

Creator:: Wevers, Mary Jo
Abstract:: An approach to understanding and managing anadromous salmon, steelhead, and sea-run cutthroat trout (Oncorhynchus spp.) based on life history and evolutionary adaptive capacities of species and stocks is presented. Species, stocks, and local populations are viewed as systems that are continuously adapting to changing environmental conditions. They have the potential...

Toward a general theory of exploitation of fish populations

Creator:: Liss, William J.
Abstract:: A possible form of a theory of exploitation of fish populations was examined. The exploitation theory was derived from a theory of community dynamics that represents the interactions between populations in a biological community with complex interrelated systems of isoclines on phase planes. The isocline systems are deduced, with a...

The effects of sewage on the distribution and abundance of benthic animals in a Puget Sound bay

Creator:: Shapeero, William L.
Abstract:: The effects of discharged sewage on physico-chemical conditions and the distribution and abundance of marine benthic animals were studied in Shilshole Bay, a part of Puget Sound, off Seattle, Washington. For over 50 years prior to 1965, when this study was initiated, 87,300 pounds (32,400 pounds BOD) per day of...

Organization and the adaptation of aquatic laboratory ecosystems to resource availability, exploitation, and a toxicant

Creator:: Woltering, Daniel Mark
Abstract:: Organization and the adaptation of aquatic laboratory ecosystems to resource availability, exploitation, and a toxicant were examined in a 34-month study. Sixteen 560-liter microcosms including prey, predator, and competitor populations were employed over a wide range of energy and habitat resource availability and exploitation of the top predator. Chronic exposure...

Classification of Icelandic watersheds and rivers to explain life history strategies of Atlantic salmon

Creator:: Gudjonsson, Sigurdur
Abstract:: A hierarchical classification system of Iceland's watersheds and rivers is presented. The classification is based on Iceland's substrate, climate, water, biota, and human cultural influences. The geological formations of Iceland are very different in character depending on their age and formation history. Three major types of formations occur: Tertiary, Plio-Pleistocene,...

Life history patterns of two allopatric clupeids : Atlantic menhaden (Brevoortia tyrannus) and gulf menhaden (B. patronus)

Creator:: Powell, Allyn B.
Abstract:: Atlantic menhaden, compared to gulf menhaden, exhibit a life history pattern that appears to be adapted to a more unpredictable reproductive environment. From experiments on laboratory-reared eggs and larvae, Atlantic menhaden have larger eggs with larger yolk volume. They are larger at hatching, utilize their yolk faster, begin feeding at...

Influence of marine environment on age and size at maturity, growth, and abundance of chum salmon, Ohcorhynchus keta (Walbaum), from Olsen Creek, Prince William Sound, Alaska

Creator:: Helle, John H.
Abstract:: Effects of the marine environment on age and size at maturity, early marine growth, and abundance of chum salmon, Oncorhynchus keta, were studied at Olsen Creek during 1959-77. Chum salmon returned to Olsen Creek as predominately 3-, 4-, and 5-year fish; however, age composition varied from year to year. The...

Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

Creator:: Taft, Oriane Williams
Abstract:: Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...

Life history strategies and tactics of striped bass (Morone saxatilis) Walbaum

Creator:: Eldridge, Maxwell B.
Abstract:: Traditional approaches to research and management of striped bass have tended to be mechanistic, numerically oriented, and based on limited life history information. In the study presented here, comprehensive conceptual perspective was used in a multivariate study of life history and evolutionary adaptation of 10 striped bass populations representing the...
