The Translocation Of Barramundi. A Discussion Paper., Makaira Pty Ltd
The Translocation Of Barramundi. A Discussion Paper., Makaira Pty Ltd
Fisheries management papers
There is recognisable economic benefit to the translocation of barramundi, but there is also a need to ensure the translocation will not adversely impact upon the genetic diversity, introduce disease or impact on the natural environment and biodiversity. This discussion paper has been prepared to provide information to assist in the assessment of the possible impact of translocation of barramundi into and within Western Australia, for the purposed of recreational stock enhancement, aquaculture development and domestic stocking. In contemplating the translocation any aquatic species, signigicant economic and social benefits must be balanced with biological and environmental risks; that is, the …

The South Coast Estuarine Fishery. A Discussion Paper., Rod Pearn, Tony Cappelluti
Fisheries management papers
This discussion paper proposes a way for the South Coast Estuarine Fishery to address issues relating to the long-term sustainable management and sharing of the fish resource.

Proposals For Community Discussion. A Quality Future For Recreational Fishing In The Gascoyne. A Five-Year Management Strategy For Recreational Fishing., Gascoyne Recreational Fishing Working Group
Fisheries management papers
Gascoyne has seen a series of rapid developments in recreational fisheries management, starting with the introduction of state-wide bag limits in 1991; followed by area specific controls at Ningaloo in 1992; landing limits in Exmouth Gulf in 1993; strict controls on the take of pink snapper in Shark Bay’s inner gulfs in 1997; new bag limits for Shark Bay in 1998; and the introduction of a management system for the charter and aquatic tour industry in 1999. The management proposals presented for community discussion in this paper are aimed at maintaining or improving the quality and diversity of the Gascoyne's …
Intermediate Rings Between A Local Domain And Its Completion, William Heinzer, Christel Rotthaus, Sylvia Wiegand
Intermediate Rings Between A Local Domain And Its Completion, William Heinzer, Christel Rotthaus, Sylvia Wiegand
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
We consider the structure of certain intermediate domains between a local Noetherian domain Rand an ideal-adic completion R* of R that arise as the intersection of R* with a field containing R. In the case where the intersection domain A can be expressed as a directed union of localized polynomial extension rings of R, the computation of A is easier. We examine conditions for this to happen. We also present examples to motivate and illustrate the concepts considered.
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
All Master's Theses
Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …
Under-Ice Diel Vertical Migrations Of Oncorhynchus Nerka And Their Zooplankton Prey, G. B. Steinhart, Wayne A. Wurtsbaugh
Under-Ice Diel Vertical Migrations Of Oncorhynchus Nerka And Their Zooplankton Prey, G. B. Steinhart, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
We used stationary hydroacoustics and measures of environmental conditions (water temperature, dissolved oxygen, light levels, and zooplankton) to determine what factors, foraging or predation risk, influenced diel vertical migrations of Oncorhynchus nerka during winter in three high-mountain lakes. The Sawtooth Valley lakes are deep, oligotrophic, glacial lakes located in central Idaho, U.S.A., and historically contained populations of anadromous O. nerka. In general, low light intensities limited foraging opportunities of O. nerka under ice, especially at night. In Stanley Lake, O. nerka underwent diel vertical migrations to exploit available light to feed. Oncorhynchus nerka occupied shallow water at night, where there …
Ontogenetic Habitat Shifts Of Juvenile Bear Lake Sculpin, J. Ruzycki, Wayne A. Wurtsbaugh
Ontogenetic Habitat Shifts Of Juvenile Bear Lake Sculpin, J. Ruzycki, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
Bear lake sculpin Cottus extensus exhibit ontogenetic habitat shifts during their initial year of life. Distribution and habitat switching was measured with bimonthly bottom-trawl surveys repeated throughout the summer. Patterns of daily growth increments on otoliths were used to measure the history of habitat residence, individual size at the time of the habitat switch, and habitat-specific growth rates. Laboratory experiments and known-age fish confirmed daily increment formation of otoliths. After dispersing during an initial pelagic larval stage, postlarval juveniles settled in both the warm, food-rich littoral zone and the cold, unproductive profundal zone. During summer, initial profundal-zone inhabitants underwent a …
