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.
So, what is the economic value of artificially cultured wheat ear fish? It is impossible to make a lot of money simply by raising wheat-ear fish, because the economic value of this fish itself is relatively low. In the northeast, even when the market is good, the wheat-ear fish can only be sold at the price of 7~ 10 yuan/kg, so it is difficult to supply the market in full.
In fact, the practice of most farmers is to use ear fish as a fish breeding variety, that is, a large number of freshwater fish such as carp, crucian carp and grass carp are matched in the breeding process, which plays a icing on the cake. In this way, a large number of fish can be harvested at the end of the year, and at the same time, additional income can be obtained through the wheat ear fish.
The above-mentioned culture mode is polyculture, and after a large number of fish fry are put in the pond every year, an additional 2.5~5 kg of wheat ear fish can be put in each mu of water surface. When the water temperature is above 18℃, the sea bream naturally reproduces. In order to improve the efficiency of aquaculture, some branches, aquatic plants and fishing nets can be artificially added in the pond as artificial fish nests.
It should be noted that the wheat ear fish should pay attention to small fish, and avoid using pyrethroids and other irritating pesticides in the breeding process, otherwise the wheat ear fish will easily die of drug poisoning.
In addition, domestic studies have proved that after 6 months of artificial breeding, the average body length of the fish can reach about 4 cm and the average weight is about 0.5 g. The average growth rate of Ophiopogon japonicus is mainly affected by water temperature: since June, the water temperature has increased, and the growth rate of Ophiopogon japonicus has gradually increased; In September, the water temperature reached its peak, and the growth rate of wheat ear fish also reached its peak.
Therefore, as long as the water temperature is well controlled, the large-scale artificial culture of wheat-ear fish is expected to achieve high yield.
To sum up, the ear of wheat is tender in meat, less in intermuscular thorns, delicious in taste and rich in nutrition, especially with high content of protein and calcium, which is very suitable for children, pregnant women and the elderly. Although wheat-ear fish has been playing the role of "wild miscellaneous fish" for a long time, with the diversification of people's diet and the improvement of living standards, fried wheat-ear fish has got rid of the embarrassing situation of "nobody cares" and is loved by more and more people.
Although there is a wide distribution and a large number of wheat-ear fish, it is quite difficult to catch a certain number of wheat-ear fish from the wild, and it is difficult to meet the market demand only by natural resources. With more and more attention paid to the economic benefits of wheat ear fish, I believe that the future wheat ear fish can also occupy a place in the field of artificial breeding, bringing more taste enjoyment to the general public!
