Habitat Suitability Index Models: Bigmouth buffalo

A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Bigmouth buffalo (Ictiobus cyprinellus), a freshwater fish. The models are scaled to produce an indices of habitat suitability between 0 (unsuitable habitat) and 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 indices (HSI's) are designed for use with the habitat evaluation procedures developed by the U.S. Fish and Wildlife Service.

Habitat Suitability Index Models: Longnose sucker

A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Longnose sucker (Catostomus catostomus), a freshwater fish. 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. Habitat suitability indexes (HSI's) are designed for use with the habitat evaluation procedures developed by the U.S. Fish and Wildlife Service.

Habitat Suitability Index Models: Smallmouth bass

A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Smallmouth bass (Micropterus dolomieui), a freshwater species. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for freshwater 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. The instream flow suitability curves are intended for use with the Instream Flow Incremental Methodology. Also included are discussions of Suitability Index (SI) curves as used by the Instream Flow Incremental Methodology (IFIM) and SI curves available for an IFIM analysis of Smallmouth bass habitat.

Habitat Suitability Index Models: Common carp

The common carp (Cyprinus carpio) is a native of Asia. It is now found on every continent except Antarctica (Jester 1974) and in all 48 contiguous States (Sigler 1958). The northern limit to carp distribution appears to be the 18° C isotherm (Keleher 1956). The common carp hybridizes in nature with the goldfish (Carassius auratus) (Bardach et al. 1972; Smith 1979).

Habitat suitability index models: Black crappie

Characteristics and habitat requirements of the black crappie (Pomoxis nigromaculatus) are described in a review of Habitat Suitability Index models. This is one in a series of publications to provide information on the habitat requirements of selected fish and wildlife species. Numerous literature sources have been consulted in an effort to consolidate scientific data on species-habitat relationships. These data have subsequently been synthesized into explicit Habitat Suitability Index (HSI) models. The models are based on suitability indices indicating habitat preferences. Indices have been formulated for variables found to affect the life cycle and survival of each species. Habitat Suitability Index (HSI) models are designed to provide information for use in impact assessment and habitat management activities. The HSI technique is a corollary to the U.S. Fish and Wildlife Service's Habitat Evaluation Procedures.

Habitat Suitability Index models: White crappie

The white crappie (Pomoxis annularis) is native to freshwater lakes and streams from the southern Great Lakes, west to Nebraska, south to Texas and Alabama, east to North Carolina, then west of the Appalachian Mountains to New York. It has been widely introduced outside this range throughout North America (Hubbs and Lagler 1958; Goodson 1966; Scott and Crossman 1973).

Habitat Suitability Index Models: Slough darter

The native range of the slough darter (Etheostoma gracile) extends from western Alabama (Smith-Vaniz 1968) to central Texas and northward in the lowland areas of the former Mississippi Embayment and the Interior Low Plateau to central Illinois (Collette 1962) and southwestern Indiana (Gerking 1945). Its distribution also includes southeast Kansas (Metcalf 1959; Cross 1967) and northeast Oklahoma (Blair 1959). Natural hybridization with the blackside darter (Percina maculata) has been recorded (Page 1976).
