Sampling Methods
For future management purposes, further population monitoring needs to be conducted. In one study, a simple dip net was found to be the best method to collect Tennessee dace. They were very productive because the species usually inhabits very small streams. Dip nets can be placed at the down stream side of a pool, and moved to the upstream side. In the larger pools and streams, a seine net was used. Seining was conducted using the standard seine method, blocking one end of a pool or sample area and kicking into the seine. An electro shocker could be helpful in larger streams, but it is unnecessary in most streams. In the same survey, minnow traps were used and proved ineffective. On separate occasions, both Tennessee dace and common creek chub were captured in minnow traps. Ten minutes later, the Tennessee dace were absent. It is assumed that they were consumed by the larger creek chub.

Famous quotes containing the word methods:
“The comparison between Coleridge and Johnson is obvious in so far as each held sway chiefly by the power of his tongue. The difference between their methods is so marked that it is tempting, but also unnecessary, to judge one to be inferior to the other. Johnson was robust, combative, and concrete; Coleridge was the opposite. The contrast was perhaps in his mind when he said of Johnson: “his bow-wow manner must have had a good deal to do with the effect produced.””
—Virginia Woolf (1882–1941)
