SMBassWB: Growth increment data for West Bearskin Lake, MN, Smallmouth Bass.

Description

Growth data from Smallmouth Bass (Micropterus dolomieu) captured in West Bearksin Lake, MN. Five samples were collected over three years (1988-1990) with two gears (fall -- trapnets, spring -- electrofishing).

Arguments

Format

A data frame of 445 observations on the following 20 variables:

species

Species of the fish (SMB for each fish in this file)

lake

Lake fish was captured in (WB for each fish in this file)

gear

Gear used to capture the fish (T=Trapnet and E=Electrofishing)

yearcap

Year fish was captured (1988, 1989, or 1990)

fish

A unique identifier for each fish

agecap

Assigned age-at-capture for the fish (from scales)

lencap

Total length-at-capture for the fish (mm)

anu1

Magnified scale radius (mm) to the 1st annulus

anu2

Magnified scale radius (mm) to the 2nd annulus

anu3

Magnified scale radius (mm) to the 3rd annulus

anu4

Magnified scale radius (mm) to the 4th annulus

anu5

Magnified scale radius (mm) to the 5th annulus

anu6

Magnified scale radius (mm) to the 6th annulus

anu7

Magnified scale radius (mm) to the 7th annulus

anu8

Magnified scale radius (mm) to the 8th annulus

anu9

Magnified scale radius (mm) to the 9th annulus

anu10

Magnified scale radius (mm) to the 10th annulus

anu11

Magnified scale radius (mm) to the 11th annulus

anu12
