The most delicious and inexpensive fish I have ever eaten is the fish with few spines. This kind of fish has bright white, delicate flesh and delicious taste. It can be cooked in soup, braised in braised sauce or steamed.

The yellow stickleback is small in size and is characterized by a row of spines on its back in front of the dorsal fin. Each pelvic fin has a sharp spine; the caudal peduncle is slender and the caudal fin is square. There are no scales, and there are an indefinite number of hard armor plates on the sides of the body. Stickleback fish are known for their reproductive behavior. Yellow stickleback fish mainly feeds on aquatic insects, molluscs, shrimps, small fish, etc. It likes to live at the bottom of ditches and grows slowly.
