Field application methods for recovery of the selective lampricide, 3-trifluoromethyl-4-nitrophenol
Colorimetric methods are described for the detection of residues of the selective lampricide, 3-trifluoromethyl-4-nitrophenol (TFM), in natural waters and fish tissues. Solvent extraction and anion exchange were used to separate and concentrate the lampricide, and to reduce high background colors which often interfere with the determinations. Data from the Pentwater and Muskegon Rivers (Michigan)

Detection and measurement of organic lampricide residues
The selective lampricide, 3-trifluoromethyl-4-nitrophenol (TFM), and its synergist, 5,2'-dichloro-4'-nitrosalicylanilide (DCN), are separable from natural waters by anion exchange. The adsorbed compounds can then be recovered from the resin as concentrates by elution with selective solvent mixtures. Measurements of the amounts of lampricides in the final concentrates can be made colorimetrically a

A review of advances in the study of diseases of fish: 1954-1964
STUDY OF DISEASE IN ANIMALS, INCLUDING MAN, has progressed rapidly in the past decade. Looking back, we find amazing success in the study of man's diseases and possibly only a little less success in studies of diseases of domesticated homeothermic animals. We who are interested in the poikilothermic animals may feel at times that we have not advanced so rapidly in our field. The reason for this ma
