Abstract:

The use of a large-meshed seine net (aperture 2 multiplied by 5 cm) in enclosed compounds was an effective method for the capture of large grass carp, Ctenopharyngodon idella (Val.), and tench, Tinca tinca L., with mean fork lengths of 42.9 cm and 38 multiplied by 3 cm and mean weights of 1 multiplied by 53 kg and 1 multiplied by 10 kg respectively. Calculated population estimates using a constant-effort removal technique showed a high degree of accuracy for grass carp, when the absolute index of population size was checked after completion of netting with an application of a commercially available rotenone formulation.
