Evaluation of Formalin and Hydrogen Peroxide Treatment Regimes on Rainbow Trout Eyed Eggs

Autor: Craig A. Soupir, Michael E. Barnes

Publikováno v: North American Journal of Aquaculture. 69:5-10

This study examined the use of antifungal chemicals at nonstandard treatment concentrations or treatment intervals during the incubation of eyed eggs of rainbow trout Oncorhynchus mykiss until hatch in vertically stacked incubation trays. Daily chemi

Reduced Formalin and Hydrogen Peroxide Treatments during Walleye Egg Incubation

Autor: Michael E. Barnes, Craig A. Soupir

Publikováno v: North American Journal of Aquaculture. 68:276-280

Formalin use was evaluated as part of an investigational new animal drug study to determine its effectiveness in controlling fungus (water molds: Saprolegniaceae) on incubating eggs of the walleye Sander vitreus. Hydrogen peroxide was also evaluated

Comparison of Creel Survey Methods on Missouri River Reservoirs

Autor: John P. Lott, Michael L. Brown, Cliff C. Stone, Craig A. Soupir

Publikováno v: North American Journal of Fisheries Management. 26:338-350

When creel survey methods such as noncontact aerial designs are applied to large water bodies, they are often biased because of scheduling difficulties and flight reductions made to reduce cost. An aerial creel survey has been used to estimate fishin

Trophic ecology of largemouth bass and northern pike in allopatric and sympatric assemblages in northern boreal lakes

Autor: Michael L. Brown, Larry W. Kallemeyn, Craig A. Soupir

Publikováno v: Canadian Journal of Zoology. 78:1759-1766

Largemouth bass (Mieropferus salmoides) and northern pike (Esox lucius) are top predators in the food chain in most aquatic environments that they occupy; however, limited infonnation exists on species interactions in the north ern reaches of large

Relative Precision among Calcified Structures for White Bass Age and Growth Assessment

Autor: Craig A. Soupir, Michael L. Brown, Brian B. Blackwell

Publikováno v: Journal of Freshwater Ecology. 12:531-538

We assessed the relative precision among scales, sagittal otoliths, and opercles for determining age and estimating the growth of 124 white bass (Morone chrysops). Percent agreement for age among the three structures was 72.1%. Scale assessments prov

Caloric Densities of Three Predatory Fishes and Their Prey in Lake Oahe, South Dakota

Autor: Scott D. Bryan, Walter G. Duffy, Craig A. Soupir, Chris E. Freiburger

Publikováno v: Journal of Freshwater Ecology. 11:153-161

We determined mean seasonal caloric density of walleye Stizostedion vitreum, chinook salmon Oncorhynchus tschawytscha, rainbow trout Oncorhynchus mykiss and ten species of prey fish from Lake Oahe, South Dakota. Age 3 and older walleye, chinook salmo
