Several methods were used to evaluate the quality of ship-processed and U.S. land-processed surimi. The fold test is useful to distinguish between high and low quality surimi but lacks the sensitivity to discriminate between surimi samples having similar yet different functional properties as measured by the punch test and torsional shear test. Moisture content of U.S. land-processed surimi was linearly correlated with several functional properties. Much work is still required to determine the relationship of the results of the various tests to the quality and sensory properties of finished products.

am appreciative for the logistical support, planning and editing of this report by Doug Perkinson and Dave Center. Also, the Montana Natural Heritage Program staff were supportive and provided follow-through in a timely manner.Don Skaar and his staff at the Fish, Wildlife and Parks, Libby field office, and Wayne Kasworm and his staff (same base) were especially supportive with equipment and lodging.Lewis Young of the Eureka Ranger District readily provided information and suggestions pertinent to achieving the study objectives. Also, my thanks to the rangers and staff at the Fortine Ranger District for providing occasional lodging and facilities during the study.Qualitative evaluations of stream habitat were used to assess differences between sites.Individual species habitat requirements were similar enough to require that quantitative measures of a number of physical, chemical, and biological conditions be made before distinctions could be determined for individual species.Electroshocking in conjunction with D-netting was the best method for sampling sculpin. Alternate sampling methods may be valuable for obtaining additional information.
