Optimal stocking density for culturing tropical soil-dwelling earthworm, pontoscolex corethrurus

The present study was carried out to determine the optimal stocking density for culturing tropical soil dwelling earthworm, Pontoscolex corethrurus. F1 generation earthworms were cultured in four different stocking densities of 1, 4, 7 and 10 worms per vessel, corresponding to field densities of 50,...
