Habitat Suitability Index Models and Instream Flow Suitability Curves: Spotted bass
Thomas E. McMahon, Glen Gebhart, O. Eugene Maughan, Patrick C. Nelson
1984, FWS/OBS 82/10.72
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...
Habitat Suitability Index Models: Larval and juvenile red drum
Jack Buckley
1984, FWS/OBS 82/10.74
A review and synthesis of existing information were used to develop a habitat model for larval and juvenile red drum. The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for estuarine areas along the Gulf of Mexico and Atlantic...
Habitat Suitability Index Models: Spotted seatrout
Paul T. Kostecki
1984, FWS/OBS 82/10.75
The estuarine spotted seatrout, a primarily estuarine species, is one of the most important sport and commercial fishes in coastal Gulf of Mexico waters (Arnold et a1. 1976). Spotted seatrout rank second by weight in catches by U.S. saltwater sport fishermen (National Marine Fisheries Services 1981) ....
Habitat Suitability Index Models: Muskrat
Arthur W. Allen, Robert D. Hoffman
1984, FWS/OBS 82/10.46
The muskrat (Ondatra zibethicus) is the most valuable semi-aquatic furbearer in North America, with a total fur trade income in the millions of dollars (Willner et al. 1980). With the exception of Florida, and coastal Georgia and South Carol ina, native and introduced populations of muskrats occur throughout most of...
