Download or read book Fish Habitat Protection Guidelines written by Sentar Consultants Ltd and published by . This book was released on 1995 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: These guidelines are intended to eliminate or minimize the impact of stream crossings and road construction on adjacent lakes and streams in Saskatchewan. The guidelines first outline the legislation and policies relating to the construction of stream crossings and roads adjacent to water bodies in the province. The guidelines then examine the effects of stream crossings, sedimentation, and erosion on fish habitat and behavior. This is followed by topics specifically related to protection of fish habitat: scheduling of construction activities to avoid conflicts with fish migration, spawning, and incubation periods; route planning to avoid conflicts with fish passage and habitat; reservation of undisturbed vegetation along edges of water bodies; design of bridges and culverts; installation of culverts and other crossings; stream crossing approaches; control of deleterious substances; road maintenance; decommissioning; and control of erosion and sedimentation. A glossary is included.

Available in PDF, EPUB and Kindle. Book excerpt: The British Columbia Forest Practices Code specifies planning and operational guidelines for each phase of timber harvesting operations around streams, lakes, and wetlands. This guide describes suitable practices to meet the objectives of the riparian management regulations within the Code, specifically the requirement to correctly identify streams on the basis of fish presence in order to ensure the protection of fish populations and habitats during all phases of forest harvesting. The guide defines the classes of streams distinguished for aquatic ecosystem and riparian zone management, identifies fish species that define a stream as fish-bearing under the Code, and describes factors influencing fish-stream identification such as stream reach, gradient, stream size, natural barriers, and fisheries sensitive zones. The guide concludes with methods for identifying fish streams, including measurement, sampling, data recording, and mapping procedures.

Download or read book An Assessment of Fish Passage Conditions at Stream Crossings Associated with the State Road System on the Seward Peninsula written by David B. Ryland and published by . This book was released on 2008 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where roads intersect streams, crossing structures can become barriers to fish passage significantly affecting fish populations by delaying, impeding, or blocking normal movements. Unrestricted movement through stream systems is necessary for anadromous and resident fish species of all age classes and life stages to maintain access to spawning, rearing, and over-wintering habitats, which are essential to maintaining viable populations. Results of stream crossing inventories in the Pacific Northwest and Alaska suggest that a majority of culverts in fish-bearing waters obstruct normal fish movements to varying degrees. The loss of freshwater habitat is often considered a central factor in the decline of wild fish stocks throughout the range of Pacific salmon. This study was undertaken to assess fish passage at stream crossings along state-maintained roads on the Seward Peninsula in northwestern Alaska. Approximately 74 percent of the stream crossings surveyed were categorized as barriers to juvenile fish; an additional 19 percent were categorized as potential barriers. At the majority of the crossings surveyed, culverts were found to constrict the stream channel and be too steep for juvenile fish passage. Steep gradient was the most common factor that contributed to any crossing being categorized as a barrier.
