Comparing fish catches taken with gill nets of different combinations of mesh sizes
Based on net selectivity curves and the pooled relative efficiency of combinations of mesh sizes, models for comparing gill‐net catches taken with different combinations of mesh sizes are presented for perch, burbot and, in more detail, for salmonids. The models enable comparison of length frequenci...

| Summary: | Based on net selectivity curves and the pooled relative efficiency of combinations of mesh sizes, models for comparing gill‐net catches taken with different combinations of mesh sizes are presented for perch, burbot and, in more detail, for salmonids. The models enable comparison of length frequencies and the numbers of fish within any length range caught with an acceptable net efficiency. A standard for comparing salmonids is proposed. |
