If mixed with fish, then there is no need to feed (mussels are to eat fish feces grow up).

Mussel farming:

1, the current mussel farming methods are mostly used in hanging and cage farming, hanging methods have a single hanging and string farming in a line hanging more than two mussels, the number of cages depending on the size of the cages (mesh cages, mesh clamps), generally to the bottom of the cage can be contacted by each mussel as appropriate.

2, pearl mussels general mu breeding ponds for 800-1200, 600-800 outside the swing, breeding density depending on the weight of the fertility, water flow, water depth and other physical and chemical, biological, with the size of the mussels to the appropriate amount of increase or decrease.

3, mussel farming has become the city outside the body of fisheries in the comprehensive development and utilization of the main production of the body, to bead-based ponds can be appropriate stocking of grass carp, bream, crucian carp, Mandarin fish, Pelteobagrus fulvidraco, etc., and a small number of silver carp, bighead carp, in order to fully tap the productive potential of the water body.

Management of mussels:

1, post-surgery management of the temporary period: after the operation of the mussels, temporary in the micro-flow water, water quality, fresh waters, rest 15-30 days.

During this period, the general suspension should not be arbitrarily turned, and may not leave the water, not to open the shell to check, so as not to affect the recovery of its body and the formation of bead capsules.

If the water is too fat, the transparency is less than 30 cm, then you need to take measures to reduce the degree of fertilization.

After one month, the mussels in the temporary aquatic area will be inspected, and the dead mussels will be removed in time, and then they will be re-hanging to the bead-cultivation area.

2, strengthen the injection, water change and oxygenation: in the absence of running water in the closed static water mussels, high temperature, shallow water, low pressure, will cause hypoxia dead mussels.

So we must add water in a timely manner, change the water or keep the water fresh and oxygenated enough to avoid the lack of oxygen mussels, mussels, beads in the case of low-oxygen growth slow.

3, timely adjustment of hanging depth: according to the water level, water temperature and seasonal changes, should be adjusted in time to raise the depth of mussels hanging.

Winter and summer should be appropriate deep hanging (40-60 cm below the surface of the water), spring and fall can be hanging shallow (15-20 cm below the surface of the water).

4, do a good job of water fertilization: such as pearl pond water quality is thin, to timely fertilization.

Fertilizer available organic fertilizer or chemical fertilizer, or both.

Organic fertilizer mountain chickens, ducks, birds are good, before using the need to add a quicklime and fermentation after rotting before application.

Chemical fertilizers are mainly urea and calcium superphosphate (dosage ratio 1:2 or 1:3), the two mixed with water and sprinkled, to do more than once, the amount of less, less施, diligently施, generally mu with urea 1 kg.

Also available splash of soybean milk (feed and fertilizer).

At the same time apply calcium fertilizer (quicklime), PH value is low more; PH value is high less.

5, the removal of adhesions: pearl mussels after hanging for some time, in the hanging mesh cages, mesh bags and mussels often attached to a large number of mud and organisms (such as algae, freshwater sponges, poly polycondensation worms, etc.), affecting the growth of pearl mussels must be cleaned on a regular basis.

In April-October, wash every other month.

6, maintenance of aquaculture facilities: in the process of aquaculture, found that the aquaculture facilities are damaged should be repaired in time to avoid economic losses.

Extended information:

Mussels are very nutritious. p>Mussels have a high nutritional value, containing protein, fat, sugar, calcium, phosphorus, iron, vitamins A, B1, B2.

Mussels contain 10.9 grams of protein per 100 grams of edible portion, 248 milligrams of calcium, 26.6 milligrams of iron, 6.23 milligrams of zinc, 305 milligrams of phosphorus, 243 micrograms of vitamin A, 20.24 micrograms of selenium, 2.3 micrograms of carotenoids, and also contains more riboflavin and other nutrients, the total energy can reach 20.71 MJ/kg.

Mussel meat has good health effects on the human body, nourishing yin and calm the liver, brighten the eyes and prevent eye diseases and other effects.
