In FESta: Fishing Effort Standardization

MGMSstd_dataset

Description

A simulated multi-gear, multi-species fisheries dataset for illustrating the application of the MGMSstd() function for multigear mean standardization of Catch Per Unit Effort (CPUE).

Usage

MGMSstd_dataset

Format

A data frame with 375 observations and 4 variables:

Year

Fishing year.

Gear

Fishing gear used for harvesting the species.

Species

Fish species for which CPUE observations are available.

CPUE

Catch per unit effort corresponding to a particular species, gear, and year combination.

Details

The dataset contains annual CPUE observations for several fish species captured by different fishing gears over multiple years. It is intended for demonstrating the estimation of nominal and standardized CPUE indices in complex multispecies and multigear fisheries.

The dataset represents a hypothetical multigear fishery in which several fishing gears exploit multiple fish species simultaneously. Each row corresponds to the CPUE value for a specific species captured by a particular fishing gear during a given year.

The dataset can be used to demonstrate:

• Calculation of gear-specific mean CPUE.

• Multigear mean standardization.

• Estimation of nominal and standardized CPUE indices.

• Visualization of temporal CPUE trends.

Source

Simulated dataset generated for illustrating the MGMSstd() methodology implemented in the FESta package.
