A Case For Site Acclimation In The Reintroduction Of The Endangered Razorback Sucker (Xyrauchen Texanus), United States Geological Survey
A Case For Site Acclimation In The Reintroduction Of The Endangered Razorback Sucker (Xyrauchen Texanus), United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
Two site-acclimation studies (Mueller and Marsh 1998, Foster and Mueller 1999) were conducted in 1997 and 1998. The primary emphasis was habitat use and dispersal but we also examined if the rapid dispersal, typically associated with hatchery-produced razorback suckers (suckers), could be mitigated by allowing fish a period of time to recover from stocking-induced stress. Findings of those studies and existing physiological literature suggest that current stocking protocols may subject stocked fish to unnecessary behavioral or physiological stress that could impact performance and ultimately survival. This report presents those findings and recommends an evaluation of existing stocking procedures for the …

Information pertaining to post-stocking dispersal and habitat use of endangered razorback sucker (Xyrauchen Texanus) is primarily limited to the adult life stage. Radio or sonic transmitters are normally surgically implanted in the fish's abdominal cavity.

The Colorado River of the American West supports a mainstream fish community that is classified as the “Big River” fishes. Four of these fishes are listed as endangered under provisions of the Endangered Species Act of 1973, as amended. Three fishes (i.e., Colorado pike minnow Ptychocheilus Lucius, humpback chub Gila cypha, and bonytail G. elegans) have been listed for over 10 years, and they have recovery plans that were prepared prior to designation of critical habitats. Recently the Colorado squawfish was renamed by the American Fisheries Society and hereafter will be refered to in this document as the Colorado pike …
