Application of semi‐quantitative electrofishing to juvenile salmonid stock surveys
A semi‐quantitative electrofishing technique is described, which has applications for assessing distribution and densities of 0+ salmonids in streams. Linear regressions of logarithmically‐transformed data satisfactorily described the relationship between numbers of 0+ Atlantic salmon ( Salmo salar...

Summary: | A semi‐quantitative electrofishing technique is described, which has applications for assessing distribution and densities of 0+ salmonids in streams. Linear regressions of logarithmically‐transformed data satisfactorily described the relationship between numbers of 0+ Atlantic salmon ( Salmo salar L.) and 0+ brown trout ( Salmo trutta L.) captured in a standard 5 min fishing and quantitative population estimates obtained using a commonly used method. Applications of the semi‐quantitative technique to management are discussed and a categorization system proposed. |
