Maisui fish can be eaten, and it tastes better when fried and fried. Golden crisp, bite by bite, is really a kind of enjoyment. Wheat ear fish used to be considered as a kind of wild miscellaneous fish, which, like vegetable fish, has no great economic value. In recent years, the wheat-ear fish in the aquatic product market has begun to emerge, and the current price is generally low, which is quite close to the people. The purchase price of Maisui fish in Tangkou is only 5~6 yuan per catty, which still has certain economic value for farmers.
What kind of fish is the wheat ear fish in the ditch? This should start with the ecological habits of the wheat ear fish, which belongs to the native species of East Asia. However, some foreign countries did not control the population size after the introduction of the fish, so the fish was included in the list of invasive species. This is mainly because this kind of fish has strong reproductive ability. Adult female fish can lay 3500~4500 eggs at a time, which are closely attached to reeds, branches, fishing nets or aquatic plants, and male fish will escort the hatching of fish eggs.
In addition, it has strong adaptability to the environment, and can survive normally in the water environment of 1~35℃, and the optimum growth water temperature is 18~25℃. May every year is the peak season for this kind of fish to lay eggs. At this time, the water temperature is often above 20℃, which is the best growth temperature for fish.
From the feeding point of view, wheat ear is an omnivorous fish, which feeds on plankton, insects, rotifers, cladocera, buds of aquatic plants and organic debris in water. The habit of "not picky about food" has won a stronger viability and a wider range of survival for the wheat ear fish. In winter, most fish such as carp can still eat normally when they enter hibernation, which can be described as "wolf nature".
In recent years, some people have taken a fancy to the high reproductive characteristics of wheat ear fish and started stocking them in reservoirs and lakes. I didn't expect to catch a lot of wheat ear fish at harvest time.
The general practice of stocking is: in April every year, the fish with a body length of 5-6 cm is selected as the parent fish, and 0.25-0.5 kg of the fish is stocked on average per mu of water surface, so that it can naturally spawn and reproduce in the reservoir. In June of that year, the eggs of the wheat ear fish will hatch. At this time, we should seize the opportunity and appropriately add organic fertilizer (per mu 10 kg) to cultivate plankton. If the harvest is good, the average yield per mu of water surface can be 10 kg of wheat ear fish, and the benefit is still acceptable.
