Figure 1 in Catching carp: a review of bigheaded carp capture strategies

Figure 1. Conceptual representation of the gear performance matrices used to evaluate gear catch rates or gear precision in differing river strata. (Step 1) Each cell (representing gear by strata) was assigned a score (see methods). Averages (± SE) across river strata and gear types (see dashed arrows) were used to compare gear performance. (Step 2) Scores from each matrix were summed to create a third matrix representing the combined Catch rates and Precision attributes.
