Fish assemblage sampling. In each of the watersheds, the fish assemblage was sampled at multiple sites between and by the Toronto and Region Conservation Authority (TRCA) and the Ontario Ministry of Natural Resources and Forestry (OMNRF) according to the Ontario Stream Assessment Protocol (OSAP—Stanfield ) (Fig. 2a) as part of a broad scale monitoring :// Habitat Assessment A general habitat assessment is crucial in evaluating the ecological integrity of a site. The assessment is done using a visually-based approach to characterizing the physical habitat structure of the stream site (Figure 7). Habitat assessment evaluates the human-induced degradation (Figure 8) of the

The aims of this study were to describe the habitat preference and its availability to fish assemblage, as well as ecology, habitat use, and habitat characteristics. We collected fish with backpack electrofishing three times during August
Riparian clearing and the removal of wood from channels have affected many streams in agricultural landscapes. As a result, these streams often have depauperate in-stream wood loads, and therefore decreased habitat complexity and lower levels of in-stream biodiversity. The introduction of wood was investigated as a possible rehabilitation technique for agricultural streams. Wood was re characteristics in the field. This information is both collected and analyzed based on a hierarchical system of regions, basins, streams, reaches, and habitat units. Supervisors are responsible for collecting the general information on regions and basins and for directing the activities of the survey crews. Survey teams will

Herrington and Donald K. Dunham. Topics: Fishes, Habitat General Sampling Procedures: Mean stream width (MSW) is an important characteristic of each stream assessment station (reach), and is used to define the length of the station and the spacing of habitat measurements (i.e., distances between transects) for most wadable streams.
The MSW is based on the mean of 10 preliminary Conservation programs for imperiled fish require a sampling method for quantifying their habitat relationships and their progress toward recovery, via abundance estimation and subsequent monitoring.
Depletion sampling is a commonly used method, although the assumptions of homogeneous capture probabilities are :// a preselected set of habitat characteristics in an entire watershed. Habitat sampling occurs in two steps (Hankin and Reeves ). During the first step, the sampling team classifies individual habitat units by habitat type and records visual observations of habitat characteristics, such as water surface area and substrate :// Graph showing results from canonical correspondence analysis of fish relative abundance and five environmental variables in the Willamette Basin, Oregon.
52 TABLES 1. Sampling strategy for habitat measurements at National Water-Quality Assessment Program protocols for sampling wadeable streams. Wadeable stream sampling may consist of fish sampling, habitat analysis, water quality analysis, social measures, and benthic macroinvertebrate analysis.
Any or all of these components may be sampled as part of a wadeable stream survey. The components sampled depend upon the objective of the stream Water and Facility Regulation.
The following major stream habitat types are colonized by macroinvertebrates and generally support macroinvertebrate diversity in stream ecosystems. Some combination of these habitats will be sampled using this multi-habitat approach to benthic sampling.

Research objectives, habitat characteristics and availability of power source dictate the type of current to be used. If fish are being collected for residue analysis, a minimum of 10 individual fish will be collected for each composite sample.
If possible, similar species should be collected at each sampling :// Fish are diverse — each species has evolved to live successfully in its specific underwater environment, from streams and lakes to the vast expanse of the ocean.
Despite the thousands of different species, all fish share common evolutionary adaptations that help them thrive in their watery :// Sampling procedures effective for large rivers are described in Gammon (), Hughes and Gammon (), and Ohio EPA ().
Typical sampling station lengths range from to m for small streams and to m in rivers, but are best determined by pilot studies.

Several factors, including the behavior of the target fish species and attributes of the physical habitat, can bias underwater counts.

Characteristics of fish community being sampled are among the biological factors affecting in shallow streams they allow to user to identify potential hazards and habitat :// Assessing Fish Populations sampling efficiency is not constant or that too small a sample has been obtained.
More inten-sive sampling may increase precision and reduce bias (White et al. ), but identifying and accounting for the ecological, demographic, or habitat-related factors that affect sampling The general results of my work on the relationship between fish and their habitat are currently being used to develop state-wide fishery objectives for stream and lake fish populations.

Integrator Sites are chosen to represent water-quality conditions of streams and rivers in heterogeneous large basins that often are affected by complex combinations of Habitat and Water Quality Evaluations General stream characteristics including woody and herbaceous vegetation, abundance of woody debris, stream habitat type, and substrate are recorded in each station.
Wetted stream width was measured at the lower, middle, and upper extent of each sample station and was collected for years. Depth was. Water sampling and analysis for selected organic contaminants and inorganic water chemistry is performed at selected wells (locations see Fig.

The RBPs are recommended methods for sampling macroinvertebrates, fish, and habitat quality in nontidal streams.
