| Abstract |
Two experiments (I and II) were performed in drainable ponds. Yellow eels Anguilla anguilla were stocked in early June at three biomasses: 10, 20 and 60 kg/ha in experiment I; and 10, 20 and 40 kg/ha in experiment II. The mean body weights were 27.0 and 24.2 g respectively. Glass eels were stocked only in experiment II at equal densities of 1600/ha. In both experiments each biomass of yellow eel was combined in a factorial design with three cyprinid communities differing in biomass and in species- and size-composition. The ponds were drained in autumn. The final body weights at draining ranged from 25.9 to 63.6 g for yellow eel and from 3.9 to 8.8 g for glass eel. The final body weights of yellow eel and of glass eel decreased with increasing biomass of yellow eel. No significant relation was found between the bream Abramis brama biomass and the growth of eel. The growth rates of yellow eel and glass eel were positively correlated in experiment II. |
