Table 1. Fish densities in the river in the three experiments.

Experiment I = low nase density; experiment II = intermediate nase density, and experiment III = high nase density. Values are the total number of individuals caught per m² and calculated stock per m² (large fish: Ricker, 1975; small fish: De Lury, 1951, given only in case of significant regression coefficients).
