Abstract
An experimental watercress – crayfish polyculture system is described. The watercress bed receives nutrient-rich effluent from a connecting trout hatchery and effectively strips nitrates, ammonia, and phosphorous from the waters. The harvested water-cress also provides a clean and easy food source for crayfish. Preliminary feeding trials indicate that the watercress combined with protein supplement provides a satisfactory crayfish diet in terms of both growth and mortality. The development of watercress-crayfish polyculture is economically promising because of three valuable outputs – cleaner water, watercress, and crayfish.
