Variation in response of channel catfish to Henneguya sp. infections (Protozoa: Myxosporidea) Variation in response of channel catfish to Henneguya sp. infections (Protozoa: Myxosporidea)

Infections in channel catfish (Ictalurus punctatus, Rafinesque) induced by the sporozoan Henneguya (Protozoa: Myxosporidea) result in seven known and diverse disease manifestations. Most outstanding is an interlamellar branchial form responsible for significant losses among immature catfish, and a unique papillomatous form. The question of whether or not the species of Henneguya involved...

Flood of April 1975 at East Lansing, Michigan Flood of April 1975 at East Lansing, Michigan

On April 18 between 5 p.m. and 12 p.m. the city of East Lansing experienced an intense rainstorm that caused the Red Cedar River to overflow its banks, resulting in the most devastating flood since 1904. During the period of flooding the U.S. Geological Survey obtained aerial photography of the East Lansing area to document the disaster. The photography has been used to show the extent...

Effects of TFM and Bayer 73 on in vivo oxygen consumption of the aquatic midge Chironomus tentans Effects of TFM and Bayer 73 on in vivo oxygen consumption of the aquatic midge Chironomus tentans

Exposure of fourth instar larvae of Chironomus tentans to 2.0‐8.0 mg/liter of TFM (3‐trifluormethyl‐4‐nitrophenol) for 6 hr at 22 ± 0.5 C in soft water resulted in a significantly increased rate of larval oxygen consumption compared to that of control larvae, as measured with the Warburg respirometer. Maximum stimulation of oxygen consumption occurred with 8.0 mg/liter of TFM, and 1.0 mg...

Toxicity of formalin, malachite green, and the mixture to four life stages of rainbow trout Toxicity of formalin, malachite green, and the mixture to four life stages of rainbow trout

Formalin, malachite green, or a mixture of them are utilized in fish culture for control of external parasites of fish and control of fungus on fish and fish eggs. Very little information is available concerning the toxicity of these compounds to fish under laboratory test conditions or the differences in sensitivity to these chemicals at various life stages. This study was designed to 1...

Hydrology and trout populations of cold-water rivers of Michigan and Wisconsin Hydrology and trout populations of cold-water rivers of Michigan and Wisconsin

Statistical multiple-regression analyses showed significant relationships between trout populations and hydrologic parameters. Parameters showing the higher levels of significance were temperature, hardness of water, percentage of gravel bottom, percentage of bottom vegetation, variability of streamflow, and discharge per unit drainage area. Trout populations increase with lower levels...
