Habitat Suitability Index Models and Instream Flow Suitability Curves: Pink salmon

A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model and instream flow suitability curves for the pink salmon (Oncorhynchus gorbuscha). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum habitat). HSI models are designed to be used with Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.

Habitat Suitability Index Models and Instream Flow Suitability Curves: Gizzard shad

A review and synthesis of existing information were used to develop habitat suitability index models and instream flow suitability curves for the gizzard shad (Dorosoma cepedianum). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum habitat). HSI models are designed to be used with Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.

Habitat Suitability Index Models: Walleye

The wall eye is native to freshwater ri vers and 1akes of Canada and the United States, with rare occurrences in brackish water (Scott and Crossman 1973). In the United States, its native range occurs primarily in drainages east of the Rocky Mountains and west of the Appalachians; however, it has been widely introduced into reservoirs outside its native range (Colby et al. 1979). Walleye hybridize with sauger (S. canadense) and blue pike (S. v. glaucum) (Scott and Crossman 1973).

Habitat Suitability Index Models: Rainbow trout

A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for rainbow trout (Salmo gairdneri), a freshwater species. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater areas of the continental United States. Other habitat suitability models found in the literature are also included. Habitat suitability indexes (HSI's) are designed for use with the habitat evaluation procedures developed by the U.S. Fish and Wildlife Service. Also included are discussions of Suitability Index (SI) curves as used in the Instream Flow Incremental Methodology (IFIM) and SI curves available for an IFIM analysis of Fallfish habitat.

Habitat Suitability Index Models and Instream Flow Suitability Curves: White sucker

The white sucker (Catostomus commersoni) is a highly adaptable, freshwater fish species found in lacustrine and riverine environments from the Mackenzie River, Hudson Bay drainage, and the Labrador Peninsula; south along the Atlantic Coast to western Georgia; along the northern extremes of the Gulf States to northern Oklahoma; north through the eastern sections of Colorado, Wyomi ng, and Montana; and through A"I berta, north-central Bri t ish Col umbi a and southeastern Yukon territory (Carlander 1969; Scott and Crossman 1973).

Habitat Suitability Index Models and Instream Flow Suitability Curves: Warmouth

The wa rmouth (Lepomi s gul osus) occurs naturally throughout the central and southeastern United States. It is distributed throughout Kansas, Iowa, and Missouri, north to southern Wisconsin, lower Michigan, Lake Erie, and western Pennsylvania, and south to Florida and west through the Gulf States to the Rio Grande (Hubbs and Lagler 1947; Larimore 1957). It has been introduced into California (Hubble 1966; Moyle 1976), Arizona (Minckley 1973), and other western states (Smith 1896).

Habitat Suitability Index Models and Instream Flow Suitability Curves: Spotted bass

The Habitat Suitability Index (HSI) models presented in this publication aid in identifying habitat variable important to the growth and survival of spotted bass (Micropterus punctulatus). Facts, ideas, and concepts obtained from the research literature and expert reviews are synthesized and presented in a format that can be used for impact assessment. The models are hypotheses of species-habitat relationships, and model users should recognize that the degree of veracity of the HSI model, SI graphs, and assumptions will vary according to geographical area and the extent of the data base for individual variables. A brief discussion of selected Suitability Index (SI) curves as used in the Instream Flow Incremental Methodology (IFIM), and a discussion of SI curves available for the IFIM analysis of Spotted bass habitat are also included.

Habitat Suitability Index Models and Instream Flow Suitability Curves: Redear sunfish

The redear sunfish (Lepomis microlophus), commonly referred to as the shellcracker, is native from the Mississippi River in Missouri and southern Indiana to North Carolina, south through Florida, and west to eastern Texas (Cole 1951; Trautman 1957; Hubbs and Lagler 1964; Wilbur 1969; Pflieger 1975). The species has been successfully introduced into Arizona, California, and southern Michigan and stocked into new waters in Oklahoma,Missouri, Ohio, Indiana, and Illinois (Cole 1951; Beland 1953; Jenkins 1955; Trautman 1957; Lopinot 1961; Hubbs and Lagler 1964; Wilbur 1969).

Habitat Suitability Index Models: Common shiner

A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for common shiner (Notropis cornutus). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for the northeastern range of the common shiner in North America. Habitat suitability indexes (HSI's) are designed for use with the habitat evaluation procedures developed by the U.S. Fish and Wildlife Service. Also included are discussions of Suitability Index (SI) curves as used in the Instream Flow Incremental Methodology (IFIM) and SI curves available for an IFIM analysis of smallmouth bass habitat.

Habitat Suitability Information: Blacknose dace

A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Blacknose dace, a freshwater species. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater, marine, and estuarine areas of the continental United States. Habitat suitability indexes (HSI's) are designed for use with the habitat evaluation procedures developed by the U.S. Fish and Wildlife Service. Also included are discussions of Suitability Index (SI) curves as used in the Instream Flow Incremental Methodology (IFIM) and SI curves available for an IFIM analysis of Blacknose dace.

Habitat Suitability Index Models: Yellow perch

A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for yellow perch (Perca flavescens). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for riverine, lacustrine, and palustrine habitat in the 48 contiguous United States. Habitat Suitability Indexes (HSI's) are designed for use with the Habitat Evaluation Procedures developed by the U.S. Fish and Wildlife Service. Also included are discussions of Suitability Index (SI) curves as used in the Instream Flow Incremental Methodology (IFIM) and SI curves available for an IFIM analysis of yellow perch habitat.
