Flower glue is made by drying the swim bladder (the organ that controls the ups and downs of fish) of large fish. Flower gum, or fish maw, is a dried product of various swim bladders, which is famous for its rich gum, also known as flower gum.

The top fish maw ranks the king of fish glue in turn: money flounder glue (yellow-lipped fish), white flower glue (large white fish), sturgeon glue (sturgeon), yellow flower glue (African bass), flounder glue (halibut) and door eel glue (door eel).

Extended data:

The growth of the swim bladder grows with the growth of the fish body until the fish body stops growing and the swim bladder stops growing. Its shape is determined by the shape of the fish body and the spatial structure of the abdominal cavity, so that the buoyancy of each point of the fish body and the gravity generated by different parts cancel each other out.

The swim bladder has the following three functions:

First, it helps the fish to rise and fall in the water, and it is also used as a stable fish. It is located in the center of the fish and can keep the center of gravity down.

Second, make the abdominal cavity of the fish have enough space to protect its internal organs and avoid damaging the internal organs due to excessive water pressure.

Thirdly, among lungfish and bearded fish, swim bladder can be used as an auxiliary respiratory organ.

Fourthly, the swim bladder can be used as a resonant cavity to generate or receive sound.

Fifthly, in an anoxic environment, the swim bladder can be used as an auxiliary respiratory organ to provide oxygen for fish.
