## Catches in removal events for Brook Trout in the Nashwaak Experimental Watersheds Project.

### Description

Catches in removal events for Brook Trout (*Salvelinus fontinalis*) in two streams in the the Nashwaak Experimental Watersheds Project on multiple dates. Includes results from Schnute (1983).

### Format

A data frame of 16 observations on the following 7 variables:

- sample: A unique identified for the sample.
- stream: Stream (
`UNM`

=Upper Narrows Mountain Brook and `Hay`

=Hyaden Brook).
- section: Section of stream. See source.
- date: Data of collections.
- first: Catch on the first removal pass.
- second: Catch on the second removal pass.
- third: Catch on the third removal pass.
- fourth: Catch on the fourth removal pass.
- Moran.N: Schnute (1983) estimate of N using the Moran (1951) method.
- Moran.NLCI: Schnute (1983) estimate of N 95% LCI using the Moran (1951) method.
- Moran.NUCI: Schnute (1983) estimate of N 95% UCI using the Moran (1951) method.
- Moran.p: Schnute (1983) estimate of p using the Moran (1951) method.
- Moran.LH: Schnute (1983) negative log likelihood using the Moran (1951) method.
- Schnute.N: Schnute (1983) estimate of N.
- Schnute.NLCI: Schnute (1983) estimate of N 95% LCI.
- Schnute.NUCI: Schnute (1983) estimate of N 95% UCI.
- Schnute.p1: Schnute (1983) estimate of p1.
- Schnute.p: Schnute (1983) estimate of p.
- Schnute.LH: Schnute (1983) negative log-likelihood.
- ChiSq: Schnute (1983) chi-square from likelihood ratio comparison of Moran and Schnute methods.
