Fishing for clams means fishing in the river.

Diaomu is a Shaanxi dialect, which means fishing in the river. River mussels are molluscs that can be found in most freshwaters. They have an oval-shaped shell outside their body. Its shell is removed and its viscera and tender meat are used for fishing. It is a good bait for carp fishing. However, be careful to choose fresh bait.

After the bait is hooked, a short hand pole of 2.7 meters or 3.6 meters is suitable. Gently swing into the fishing spot. The water depth at the fishing spot is about 2 meters. There are many fish but few small fish in the deep water near the shore. Do not throw the hook bait hard to prevent it from falling off. When using field snails as bait specifically for fishing herrings, do not break the shells to avoid being swallowed by other fish before the herrings find them. This will defeat the purpose of fishing for big herrings.

Introduction to river mussels

River mussels are the collective name for a class of animals belonging to the family Molluscidae. In some places, they are called clam shells and wailers. Lives at the bottom of freshwater lakes, ponds, rivers, etc., half buried in mud and sand. The meat is edible and can also be used as bait for fish and poultry and as feed for poultry and livestock.

In some areas, freshwater pearl clams are used to raise pearls. The main species used to raise pearls are the triangular sail clam and the ruffled crown clam. The inlet and outlet water pipes at the rear end of the clam body are exposed, and water can flow into and out of the mantle cavity to complete functions such as feeding, breathing, and excretion of feces and metabolites. It filters and feeds on tiny organisms and organic matter particles in the water, and also eats small microorganisms.

The shell shape varies, and the two shells are equal. The carvings on the top of the shell are often concentric circles or broken lines, but they are somewhat degraded. The hinge part changes greatly, sometimes with pseudo-primary teeth and an external ligament. The septal membrane between the gill lobes is intact and arranged parallel to the gill filaments. The posterior part of the outer lobe of the outer gills is healed with the mantle, and there are gill water tubes. The openings of the gills and anus are completely separated by a septum.
