A model for understanding the influence of selective and nonselective harvest on fish populations

Creator:: Hirai, Takayuki
Abstract:: To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

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...

The dynamics of exploited guppy populations exposed to dieldrin

Creator:: Liss, William J.
Abstract:: Sixteen populations of guppies (Poecilia reticulata) were established in laboratory aquariums. Eight populations were exposed to dieldrin at a mean concentration of 0.525 ppb in the water and 2.11 ppm in the food, tubificid worms. Eight populations received control water and food. All populations were fed three grams of tubificid...

A preliminary investigation of the spotted owl in Oregon

Creator:: Forsman, Eric D.
Abstract:: Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One-hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least...

Range-use estimation and encounter probability for juvenile Steller sea lions (Eumetopias jubatus) in the Prince William Sound-Kenai Fjords region of Alaska

Creator:: Meck, Stephen R.
Abstract:: Range, areas of concentrated activity, and dispersal characteristics for juvenile Steller sea lions Eumetopias jubatus in the endangered western population (west of 144° W in the Gulf of Alaska) are poorly understood. This study quantified space use by analyzing post-release telemetric tracking data from satellite transmitters externally attached to n...
