Steller sea lions (Eumetopias jubatus) of Oregon and Northern California: seasonal haulout abundance patterns, movements of marked juveniles, and effects of hot-iron branding on apparent survival of pups at Rogue Reef

Creator:: Scordino, Jonathan
Abstract:: The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...

Some chronic effects of exposure to kraft mill effluent on juvenile chinook salmon

Creator:: Tokar, Erick M.
Abstract:: The effects of sublethal concentrations of kraft mill effluents (KME) on the growth, food consumption, and swimming ability of juvenile chinook salmon, Oncorhynchus tschawytscha (Walbaum), were studied from February 1966 to May, 1967. The KME used in these studies was obtained from two pulp and paper mills producing paper from...

The effects of different otolith ageing techniques on estimates of growth and mortality for two species of rockfishes, Sebastes pinniger and Sebastes diploproa

Creator:: Wilson, Christopher D.
Abstract:: The use of some age determination methods may result in the incorrect age structure of fish populations. This in turn may lead to incorporation of inappropriate data into models used for stock management. Otoliths are commonly used for determining the age of fishes, and ages based on the whole otoliths...

Experimental analysis of intra- and interspecific competitive interactions between cutthroat trout and sculpins in small streams

Creator:: Ramirez, Ben S.
Abstract:: In the Pacific Northwest ecoregion of North America, sculpins represent a major constituent of freshwater assemblages in coastal rivers. Based on their prevalence and abundance, sculpins are likely important ecologically, yet little is known of their interactions with co-occurring species, such as widely studied salmon and trout (salmonines). In this...

Natal source contributions of Pacific cod (Gadus macrocephalus) recruits in the southeastern Bering Sea

Creator:: DiMaria, Ruth A.
Abstract:: Effective and sustainable fisheries management not only depends on identifying and defining stocks (fundamental unit of management), but also on having knowledge of factors influencing the abundance, distribution and connectivity of stocks. Population structure of Pacific cod (Gadus macrocephalus) in the southeastern Bering Sea (EBS) remains unresolved although genetic data...

An Integrated Approach to the Investigation of Age, Growth and Population Dynamics of Burrowing Thalassinidean Shrimps in a U.S. West Coast Estuary

Creator:: Bosley, Katelyn Marie
Abstract:: Two indigenous species of burrowing shrimp inhabit and often dominate the intertidal zone of estuaries along the US West Coast, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species are considered ecosystem engineers and play a role in maintaining estuarine health and ecosystem function. They...

The effect of landscape topography and in-stream habitat on the distribution, growth, and survival of Lahontan cutthroat trout (Oncorhynchus clarki henshawi) in a high desert watershed

Creator:: Boxall, George D.
Abstract:: Lahontan cutthroat trout (LCT) (Oncorhynchus clarki henshawi) are currently limited in their distribution to a patchwork of small isolated populations, the result of habitat degradation and natural variation in landscape and in-stream conditions. The objectives of this study were to determine how landscape level topographic features influence LCT distribution patterns....

Evaluation of baits and baiting techniques for Belding's ground squirrels

Creator:: Sullins, George Lamont
Abstract:: Quantitative data concerning bait preference and bait application were collected for Belding's ground squirrels (Spermophilus beldingi) during February-July 1975. Bait materials tested for preference were crimped oats, oatgroats, whole wheat, barley, rolled wheat, rye, chopped lettuce, chopped apple, oatgroats + Rhodamine B dye, oatgroats + starch paste, oatgroats + Rhoplex...

Food habits and species composition of neritic reef fishes off Depoe Bay, Oregon

Creator:: Steiner, Richard George
Abstract:: The distribution and trophic ecology of neritic reef fishes was studied to provide biological information useful in conserving these stocks. Houk and line fishing was conducted from July 1976 to July 1977 on neritic reefs within 5 km of the Oregon coast adjacent to Depoe Bay. Sampling was designed to...
