Surface mining in the oil sands region of Alberta, Canada, often requires that mining operators drain lakes or divert streams to access the underlying ore. “Compensation lakes” can be constructed to create new fish habitat to offset the loss of fish habitat due to mining activity and to satisfy conditions under a project’s Fisheries Act Authorization. The design of these lakes requires prediction of future water temperature and dissolved oxygen levels to determine the suitability of the new habitat for fish. These predictions are made using a calibrated hydrodynamic and water quality model. Un

In riverine species, gene flow is determined by species biology, riverine architecture and flow regime.

Toxaphene offers a case study on the history of toxic contamination in Lake Superior fish. How did chemicals such as toxaphene make their way into fish in the postwar era? How did governments and communities around the Great Lakes struggle to comprehend and then control these toxics? This chapter explores the intersection of human culture with the pollutants that have made their way into water bodies — and the bodies of fish and the people who eat those fish — everywhere. Fish is a healthy source of protein that we’re encouraged to eat, and eating fish is also of great cultural significance to people, particularly tribal communities, throughout the Great Lakes region. But the potential toxicity of fish today forces people to make difficult trade-offs: How much fish do you eat when it’s culturally important? How much do you eat when you’re pregnant?

<em>Abstract</em>.—In Lake Martin (16,000 ha), Alabama, black bass <em>Micropterus </em>spp. tournaments occur nearly every weekend at a single site (Wind Creek State Park [WCSP]), which could cause fish to accumulate at this release site and potentially cause negative impacts to the population. Over a 7-month period, nearly 6,600 tour-nament-caught largemouth bass <em>M. salmoides </em>and spotted bass <em>M. punctulatus </em>were injected with a coded wire tag at different body locations before release at WCSP. After release, black bass were collected with electrofishing up to 1.5 years following release at 0–10 km from the release site and scanned for a tag. Although variable, a substantial proportion (10–70%) of tournament-caught black bass comprised the black bass population within 3 km of WCSP up to 3 months after release. After 3 months, proportions of tagged black bass within 10 km of WCSP decreased dramatically and by an order of magnitude after 1 year, which strongly suggested that these fish dispersed from WCSP. Over a 2- to 70-d period after release from a tournament, relative weights of tournament-released black bass were typically less than fish not released in tournaments. In addition, we collected and aged black bass throughout Lake Martin; relative weights of both black bass species were less and spotted bass growth was lower within 10 km of WCSP compared to other regions of Lake Martin. Even though black bass dispersed from the WCSP release site, these negative population effects were attributed to the constant translocation and accumulation of tournament-caught fish in this region of Lake Martin. In water bodies such as Lake Martin where mass translocation of black bass occurs annually at a single site, the use of live-release boats to transport tournament-caught black bass and the promotion and use of alternative release sites should be encouraged to reduce possible localized negative population effects.

Abstract:
<i>Abstract</i>.—Recovery of Brook Trout <i>Salvelinus fontinalis</i> in an Adirondack (New York, USA) lake that was subject to anthropogenic acidification provides a remarkable example of fishery improvement in response to environmental regulation. Studies initiated in the 1950s following a steady decline in Brook Trout populations helped document this recovery. Unsuccessful efforts to maintain a fishery in Honnedaga Lake with hatchery-reared fish in the 1950s forced managers to look beyond stocking, the primary approach employed until that time. As a result, fishery scientists collaborated in the 1960s and 1970s with researchers from other disciplines, providing a broad understanding of atmospheric inputs, watershed processes, and chemical interactions influencing lakes and streams. Extensive studies in the 1980s confirmed the connection between Brook Trout mortality and airborne emissions of strong acid nitrogen and sulfur compounds that released toxic inorganic aluminum from increasingly acidic soils. Political debates in that decade focused on federal regulatory efforts to reduce these emissions, which culminated in passage of the Clean Air Act Amendments of 1990. Within the next decade, Brook Trout that took refuge within a few well-buffered, groundwater-fed tributaries began to recolonize Honnedaga Lake as conditions improved in the main lake due to reduced atmospheric deposition of sulfur dioxide and nitrogen oxides. Since then, management of Honnedaga Lake in the 21st century relied upon natural reproduction by wild Brook Trout. Ultimately, social and political decisions made far away from the Adirondack Mountain region developed regulations that fostered recovery of the Honnedaga Lake fishery by restoring necessary water-chemistry conditions. The recovery of Honnedaga Lake highlights three lessons. First, environment and habitat conditions must be suitable before fishery management actions can be effective. This criterion requires a broad understanding of environmental conditions that sustain fisheries, incorporating insights from atmospheric sciences, geology, and limnology. Second, natural reproduction of Brook Trout in Honnedaga Lake successfully increased population abundance without the additional intervention of stocking hatchery-reared fish. Finally, successful management of Honnedaga Lake required political support and regulatory action from beyond the Adirondack region, as well as media attention.

Abstract:
<em>Abstract.</em>—Assessments of stream fish or benthos assemblages normally involve a contrast of conditions at test sites to conditions represented by regional reference sites that are either minimally or least disturbed. Identification of reference sites is difficult and normally involves a variety of subjective criteria. The development of reference models for stream fish and benthos in the Canadian tributaries of Lake Ontario is particularly challenging because there are few undeveloped areas and there is no consensus on criteria for a least-disturbed condition. Rather than identify sites as representing a least-disturbed condition, we developed a series of models that relate the existing biophysical condition of streams (i.e., the fish, benthos, and instream habitat) to landscape (i.e., slope, geology, catchment area) and land use/land cover (percent impervious cover [PIC]). Relationships between indices of biophysical condition and PIC can be used to hindcast or estimate the expected biophysical condition at a variety of land cover scenarios. The models cannot be used to predict conditions outside the calibration data range, but this approach does allow us to make use of a disturbance gradient and make predictions with a minimal number of least-disturbed sites. The difference between the hindcast reference and present day conditions is an estimate of present-day impacts. Results from this exercise provided an estimate of the magnitude of impairment of streams in the Canadian portion of the Lake Ontario region.

Abstract:
Rainfall time series data from three sites (Kinshasa, Luki, and Mabali) in the western Democratic Republic of Congo were analyzed using regression analysis; rainfall intensities decreased in all three sites. The Congo Basin waters will follow the equation y = -20894x + 5483.16; R2 = 0.7945. The model suggests 18%-loss of the Congo Basin water volume and 7%-decrease for fish biomasses by 2025. Financial incomes generated by fishing will decrease by 11% by 2040 compared with 1998 levels. About 51% of women (N= 408,173) from the Lake Tumba Landscape fish; their revenues decreased by 11% between 2005 and 2010. If this trend continues, women's revenues will decrease by 59% by 2040.

Abstract:
This chapter looks at three more regions of North America: the Columbia Plateau and adjacent areas of the Pacific Northwest Coast; the Great Basin; and California. It also focuses on three main themes: the development of new identities as many groups adapted aspects of the lifestyle and customs of those on the Plains and more coherent tribal entities emerged; raiding for captives; and raiding for horses. A fourth topic, which casts these into relief, is why some groups rejected the horse, or chose to adopt it very late in their history. The Great Basin was the first of the three areas to receive the horse. It is an arid region of desert, salt lakes, and mountains where rainfall is unpredictable and low, but increases eastward (Plate 15). Except for the Colorado along its southern edge and the headwaters in the rockies of streams draining towards the Missouri, none of its rivers reach the sea. Fremont farmers had once made a living across Utah, but by the 1600s cultivation was restricted to a few groups in the south and west. Elsewhere, the Basin’s inhabitants depended entirely on hunting and gathering, though strategies like burning enhanced the productivity of wild plants and game. Very broadly, two subsistence patterns were followed: one emphasized fish and waterfowl around wetlands, the other a more mobile, broadly based foraging economy in deserts and mountains in which pine nuts (piñons), grass seeds, rabbits, and larger game were important. Except for the Washoe near Lake Tahoe in eastern California, all the region’s historic inhabitants spoke Numic languages. Major groups included Utes in the southeast, Shoshones in the north and centre, and Paiutes in the west and southwest. To the north of the Great Basin lies the Plateau, centred on the Columbia River and its tributaries, which collectively send their waters into the Pacific Ocean (Plate 16). Coniferous forest covers its northern and eastern parts (including several ranges running parallel to but west of the Rockies), but the drier, hilly country of Oregon and eastern Washington is more steppe-like, with sagebrush common and trees more localized.

Hármas-Koros river lies between the mouth of the Tisza and the city Békés. In the nineteenth century, the work of regulatory her bed was made, which resulted in 44 oxbow lakes were created, of which 36 still exist till today. In presented work 14 oxbow lakes was selected and the following objectives were carried out: 1. The classification of oxbow lakes based on selected criteria: the manner and intensity of water exchange, sediment thickness, redox potential, usage, ichtiofouna. 2. The assessment of the state of spawning and its impact on ichtiofauna. 3. Determination the best methods of wate

Abstract:
Since the early 1980’s TransCanada PipeLines Ltd. (TransCanada) has employed a number of stream bank stabilization measures in an effort to minimize the loss of fish habitat and to reduce the risk of long term erosion and sedimentation. Traditional stream crossing stabilization involved the re-contouring of streambanks to a stable slope (generally 2:1) and then lining the banks with rock armour and seeding. TransCanada began using alternate techniques, primarily log-walls in 1981. Since 1981 TransCanada has evolved the use stream bank stabilization techniques to include bio-stabilization techn

Abstract:
Assessing the potential environmental and human effects of deploying renewable energy along our coasts, on the Outer Continental Shelf, and in the Great Lakes requires a new risk paradigm. Evaluating potential risks requires a consistent program of research over time that collects relevant data by each sectoral area, such as bat and bird collisions, entanglement with mammals and fish, safety within shipping lanes, etc. Data collection alone, however, will not lead to better decisionmaking. Arriving at a broad and integrated risk profile of environmental and human effects is beyond a linear pro

Abstract:
The Greater Yellowstone Area (GYA) is one of the last remaining large and nearly intact temperate ecosystems on Earth (Reese 1984; NPSa undated). GYA was originally defined in the 1970s as the Greater Yellowstone Ecosystem, which encompassed the minimum range of the grizzly bear (Schullery 1992). The boundary was enlarged through time and now includes about 22 million acres (8.9 million ha) in northwestern Wyoming, south central Montana, and eastern Idaho. Two national parks, five national forests, three wildlife refuges, 20 counties, and state and private lands lie within the GYA boundary. GY
