Topmouth gudgeon market price per jin, breeding season, food, and farming techniques

The topmouth gudgeon is a fish of the suborder Cyprinoidei, family Cyprinidae, subfamily Gobioninae, genus Pseudorasbora, and is an important economic fish in our country. Today, the editor will introduce to you what is the market price of topmouth gudgeon per jin?When does it breed? What does it eat?What are the farming techniques?

I. What is the market price of topmouth gudgeon per jin?

It is understood that the current market price of topmouth gudgeon is around 20-25 yuan per jin. The topmouth gudgeon is extremely widely distributed, and its traces can be found in almost all freshwater waters. Specifically, however, topmouth gudgeon are more numerous in still-water areas and waters with low transparency, while they are rare in waters with fast currents and greater depth.

II. When does it breed? What does it eat?

The topmouth gudgeon breeds from May to June, laying adhesive eggs. The male fish exhibits egg-guarding behavior. It is small in size and has no economic value. It is widely distributed throughout our country except the Qinghai-Tibet Plateau.

The topmouth gudgeon likes to take food in its mouth and break it into pieces. Therefore, whether it is earthworms, red worms, or dough bait, it actively snatches the food, and often runs off with it in its mouth. If you are fishing for topmouth gudgeon, the best way to prevent them from disturbing the hook is to work on the bait. First, the bait should be large; second, it should be hard; third, granular baits such as corn kernels, dried tofu, grasshoppers, dry synthetic pellet bait, and so on can all avoid their interference.

III. What are the farming techniques for topmouth gudgeon?

1. Feed feeding

The topmouth gudgeon is an omnivorous fish that mainly feeds on zooplankton. During farming, it can be fed with oil bran or homemade compound feed. The feed formula is 38% domestic fish meal, 21% rapeseed meal, 12% corn flour, and 29% wheat flour. Adhere to the principle of “four fixed and four observations.” Under normal circumstances, feed twice a day, with the feeding amount at about 5% of the fish body weight in the pond.

2. Water quality management

In the early stage of fry rearing, maintain a relatively low water level, generally 50-80 cm, which can increase the density of bait organisms per unit of pond water and the accumulated temperature of the pond water, which is conducive to the feeding and growth of the fry stocked in the pond. As the fish grow and the water temperature rises, continuously deepen the water level, generally adding water once a week, about 20 cm each time. Due to heavy feeding, the pond water easily becomes fertile. At this time, water quality can be improved through reasonable water addition and fertilization. When necessary, adopt uninterrupted circulating micro-flow water, generally changing the water once every 5 days or so, with each water change amounting to 1/5 of the pond water, and applying microbial preparations once every 10-15 days.

3. Disease prevention and control

Adhere to the policy of “treat when diseased, prevent when disease-free, combine prevention and treatment, with prevention as the priority.” In the early rearing stage, mainly harmful organisms such as cyclops and tadpoles are found. Use 0.3-0.5 mg per liter of crystallized trichlorfon to kill them, and promptly remove the tadpoles from the water. To prevent the occurrence of some bacterial diseases, regularly splash the entire pond with bactericidal and insecticidal drugs such as strong chlorine essence, chlorine dioxide, avermectin, or deltamethrin. Strictly carry out disease prevention and control in accordance with the “Guidelines for the Use of Fishery Drugs,” and do not use prohibited drugs.
