bonito: Data from an age and growth study of the pacific bonito.

Description Usage Format Details Source

Description

Growth increment data derived from tagging experiments on Pacific bonito (Sarda chiliensis) used to illustrate Francis's maximum likelihood method estimation of growth and growth variability (1988).

Usage

1

Format

A data frame with 138 observations on the following 4 variables.

T1

a numeric vector describing the release date

T2

a numeric vector describing the recovery date

L1

a numeric vector describing the length at release in cenitmeters

L2

a numeric vector describing the length at recapture in centimeters

Details

Note that Francis (1988) has discarded several records from the original dataset collected by Campbell et al. (1975).
