Ever since earthen ponds have been used for fish cultivation, the necessity of dike protection against erosion has existed. Various materials and methods have been developed in the hydraulic industry to protect earthen structures against water, but their application in fish ponds is costly. Based on experiences gained during the last 15 years in the Fish Culture Research Institute, Hungary, a new slope-protection method has been developed that is cheap, simple, and becomes an integral part of the fish pond environment. A NETLON plastic mesh binds the floating organic materials and forms a flexible supporting medium for the plants growing on the slope, thus providing a self-regenerating biological protection strip around the fish pond. A modified version of the above-mentioned protection method has also been developed for fish ponds where the dikes are highly exposed to wave action. This method combines the advantages of the conventional rigid concrete and the flexible plastic-lining methods by using a thin concrete layer with NETLON plastic-mesh reinforcement. The special large-size concrete slabs follow the contours of the dike. The slabs can be prefabricated and easily installed.
