Halibut Data

### Description

A list containing two time series, annual catch per unit effort (CPUE), and exploitable biomass of Pacific halibut for the years 1935 through 1989.
The list has the following components:

### Arguments

cpue | the catch per unit effort in pounds of halibut per skate. A skate is 1800 feet of line with baited hooks attached at 18 foot intervals. The data are independent observations.
biomass | an estimate of the exploitable biomass in millions of pounds. The time series is estimated from a nonlinear least squares fit to annual measures of catch stratified by age and total effort.
