The goal of these techniques is to give an overall look at the health and structure of fish populations. Currently the analysis focuses on largemouth bass (aka LMB). The data for the analysis is collected for each lake during spring electrofishing surveys and represent the number of fish collected in one hour of electrofishing. The analysis covers fish growth, the ability for the population to sustain itself (i.e. recruitment), and overall population structure as it pertains to fish size (i.e. how many and how big fish are).
The parameters listed below are rated for each lake for each year of data based on the following table. The score of each parameter can range from 1 to 4 (1 = Poor, 2 = Fair, 3 = Good, 4 = Excellent). For example, if 25 bass sized 12-14.9 inches are collected per hour, it would receive a 2 or a FAIR rating.
- Length at Age 3 (Growth)
- Number of Age 1 Bass (Recruitment)
- Number of Bass 12.0 to 14.9 Inches (Population Structure)
- Number of Bass 15 inches and Longer (Population Structure)
- Number of Bass 20 inches and Longer (Population Structure)
