The shrimp fishing takes place at low tide, both in summer and in winter, for about two hours, i.e. one hour before and one hour after low water. The fishermen, clad in traditional southwester, bright yellow oilskins and rubber waders, climb into the saddle. A brief word of command, the lines between collar and net tighten and off they go. Breast deep in water, the horses advance at a steady pace, often side by side, dragging the nets up which scoop up both wanted and unwanted prey from the bottom. From time to time, the fishermen and his mount leave the water to empty the net and to put the contents into two wicker baskets fixed on each side of the horse. Usually the horse is a robust stallion of the Brabant or Hainaut breed, for this work requires exceptional strenght and powers of resistance.
