Fishing is inseparable from fishing nets. Different freshwater aquatic products use different fishing nets. In the past, fishing nets were all woven by hand. The basic tools for making nets are the qing and qing board. When making a net, first wrap the net line around the qing, and then start to make a knot. Different fishing nets choose different net lines, ranging from thin silk nets to thick river nets. The size of the mesh of different fishing nets is different, ranging from small shrimp nets to large river nets. The size of the qing and qing board selected for different mesh sizes is also different. No matter what kind of net, it is first made into a net sheet and then combined, or a basic net sheet is first tied, and then other parts are further tied on the basic net sheet. Corresponding to this, there are also a series of fishery production customs, which are very distinctive. Due to changes in production methods, wild fish are constantly decreasing, and many freshwater fishing techniques have not been passed down. Now there are only shrimp catching with scoop nets, silk net fishing, net fishing, hook fishing, centipede cage fishing, clams and snails, shrimp fishing with scoop nets, and inner pond nets. Jiashan freshwater fishing customs have been included in the third batch of Jiaxing City's intangible cultural heritage list. Information source: Jiaxing Library Information source: Jiaxing Library
