The platinum is one of the most commonly eaten freshwater fish, with small heads, fine meat but more pricks, and we usually use it for red burning, which tastes very good. In particular, wild mackerel tastes sweeter, but in smaller quantities. Salmons are of high nutritional value and contain proteins and trace elements for humans. So how much for 2019? How to grow high yields
One, 2019. How much is a pound
In 2019, the price of mackerel remained almost at around $4-8 per pound, although the size of different regions, different markets, the mackerel itself could influence price changes。
The following is based on the quotes from the relevant website:
The price of fish is 5. 7 yuan per pound at the hunan samsung farmer's by-products market; $5 yuan per pound at the hunan chang shama king's whole vegetables market; 4. 3 yuan per pound at the hubei wuhan sands agricultural by-products market; $7 yuan per pound at the north wholesale agricultural products market in hubei wuhan city; 7. 5 yuan per pound at the west vegetables centre at shi jia jia hashi; $6. 3 yuan per pound at the new zone wholesty agricultural products market in the peking dai district; and $6 yuan per pound at the river soo-ling farm by-products market。
The above-mentioned market prices are relatively small, and the price of the herring in hunan lake north is lower than the price of the herring in beijing and hebei in the north, depending on their needs。
Ii. How does the mackerel produce high yields
1. Selected saplings
Choosing the seedlings is a major step towards success, and it is also one of the key factors in the high yield of the fish. We usually choose to buy fish seedlings on the formal market, with high levels of activity, early sterilization, etc., so that transport can reduce the mortality of fish seedlings。
Note the density of fish seedlings
The density of seedlings is determined on the basis of the size of the pond, water quality, etc., and a certain amount of growth space is generally reserved。
3. Mixed species
To achieve a high yield of mackerel is not to say that it is exclusively fished in ponds, but that it is necessary to mix and feed with other fish, such as mackerel, which is a good option, bearing in mind that it cannot be dropped too soon, otherwise it may affect its domestication。
4. Scientific feeding
In addition to eating algae, fertilizers and small fish shrimps in ponds, the platinum is required to regularly feed some protein-rich nutrients and to increase fattening. However, care should be taken to keep water quality clean and to dispose of the remaining feed residues on the pond surface in a timely manner in order to prevent contamination of the water quality and the occurrence of oxygen deficiency in the gillfish。
5. Daily patrols
In addition to feeding fish, care is normally taken to see whether there is sufficient oxygen capacity in the morning and evening, to increase pond water in the summer, and to prevent the occurrence of a runoff in thunderstorm weather。
Summarised by the fact that the mackerel is a fine, expensive and easy to feed and a more economically efficient freshwater fish。
