(Japanese: bamboo wheel, ちくわ, Japanese Roman character: Tikuwa), commonly known as poodle fish eggs, poodle balls, poodle rolls or poodle in Hong Kong and Macao, was originally a snack that mixed fish paste, flour, protein and seasonings, wrapped on bamboo sticks and twigs, and roasted or steamed, but now it is mostly used. People put salt, sugar, starch, protein, etc. into the fish meat of Mingtai fish, shark, flying fish, Carassius auratus, etc., and put them in bamboo rings, which are clamped with thick sticks made of bamboo or metal, and then roasted or steamed. Bamboo wheels are hollow cylindrical, most of which are 2 cm in diameter and 4-6 cm in length, with light yellow head and tail, brown middle and wrinkled surface, as if they had been roasted. According to different regions, fish used, production forms and tastes, bamboo wheels have their own characteristics. On the other hand, bamboo wheel is used as dog food because of its low cost, low fat content and high protein content.
