What kind of natural environment was indispensable for the production of ancient fishery agriculture?

China's four agricultural cultures are gradually formed in the process of agricultural development. The development of agriculture is first in hilly areas, then rivers and plains, and then mountains and grasslands. The origin of agriculture is neither in mountainous areas nor in river plains, but in hilly areas or platforms beside rivers. Poor mountain conditions, flooding rivers and swamps, hilly areas or riverside platforms have a variety of ecological flora, which can be used for hunting, animals and plants for domestication, as well as small pieces of cultivated land and water sources, making it an ideal place for agricultural origin.

After agriculture originated in hilly areas, after a long period of reclamation, the second step is to advance to river plain areas. After drainage, the land is fertile and rich in water resources, suitable for crop planting, and gradually developed into a plain farming cultural area, which is an ideal place for agricultural production. When the plain area is saturated, the third step is to spread to poor mountainous areas and grassland areas. The formation of grassland animal husbandry cultural area and mountain hunting cultural area is the development process of "exhausting the land (wasteland) and exhausting the mountains" in history.

Fishery culture was very popular in Neolithic Age, and waterline, net line and fishing line on pottery were very common. Fishermen fish and eat fish and decorate them with fish bones. All kinds of fish pictures, such as conjoined fish, mutant fish, mermaid and bird fish, have rich cultural meanings. After entering the agricultural society, fisheries are concentrated in large rivers, banks of large rivers, around lakes and coastal areas.

There are many inland rivers and lakes in China, and fishermen make a living by fishing. They go into the water, go into the water, take the boat as their home, and their lives are very mobile. Fishermen's special mode of production has formed a unique lifestyle, unique habits, taboos and beliefs. China has a long coastline, and sea fishing is the main content of coastal fishing village economy. Fishing at sea is seasonal and risky, and the reverence and belief in Poseidon is prevalent among fishermen.
