Their method is to use reasonable breeding methods, introduce groundwater, select fish suitable for survival in the local ecological environment, and choose to build fish ponds in river valley areas, adhering to the principle of adapting measures to local conditions.

Israel is located on the southeast coast of the Mediterranean Sea. The local climate is Mediterranean. Summers are supposed to be dry and hot, and winters are cold and humid. However, the place Israel chose to build fish ponds is a river valley area. Due to the influence of natural factors, the summers here are hot and humid and the winters are cold and rainy.

The river valley area has a good ecological environment and provides a good living environment for fish.

The largest fish pond in Israel is located in the Jordan Valley, and its aquaculture accounts for more than 80% of the country's total.

Although Israel has few freshwater resources, fish farming does not require freshwater resources. Fish can be raised even in water with high salinity. The Israeli people introduce groundwater to build artificial fish ponds. Moreover, Israel is in a subtropical area, and most of the groundwater is groundwater.

Hot water, there is no need to worry about fish death due to too low water temperature in winter.

Although people in Israel have introduced groundwater to build artificial fish ponds, groundwater resources are also very precious in water-poor areas like Israel. Faced with this problem, they adjust when to breed and harvest fish ponds according to climate changes.

, and after harvesting, they will save the remaining water to other fish ponds for secondary use.

Moreover, they also fill the fish ponds with inflatable plastic foam, which facilitates the biological filter circulation of the water, so in Israel they only replace the water in the fish ponds on average every three years to maximize resource utilization.

For the fish species they chose tilapia, because tilapia can survive in subtropical climate conditions and does not have many requirements for food, and mullet, because mullet can be mixed with other fish, Israeli production

The largest fish is tilapia, and tilapia is also very popular with locals. Israel’s current national aquatic production is 1,700 tons, which has fully met the country’s people’s demand for fish and has begun exporting abroad.
