Résumé

Catchability coefficients (q) of 366-m and 732-m trammel nets set along the shore in a rectangular shape were determined for selected fish species, utilizing noise and sublethal rotenone strike methods. Catachbility coefficients ranged from 0 to 1 for both trammel nets; 65% and 75% of the values for the 366-m and 732-m nets, respectively, were less than 0.1. Only the perpendicular strike method may have affected the catch efficiency of the nets, but the effect was not consistent among all species. Catchability coefficients were slightly higher when fish too small to be caught in the net were removed from the calculations. Despite the wide range of catchability coefficients among species, trammel nets struck with noise can be used to detect gross changes in abundance (standing stock) of many estuarine fishes. Increases in trammel net efficiency may be obtained by improvement in striking techniques or changes in net design, such as use of less visible monofilament webbing.
