Fry bone fry cultivation

The annual splash of our bony fish fry is starting to sprout again. Now I will tell you about the technical points of cultivating flower buds into summer flowers so as to give you a reference.

First of all, let's take a look at the growth rate of the Bony fish. Generally, it can only grow for a year (60 to 80 tails or 100 to 120 tails for a catty) to 0.2 to 0.5 catties, and the Bison fish are generally Cultivated. The average fishmonger also received 0.2 to 0.5 pounds of bone fish on the market.

1: Preparation of fishponds: First drain the water to empty the fishpond; generally disinfect the fishponds around April 10th, and then order the seedlings from the supplier, and fill the water one day in advance. The purpose mesh filter, so as not to bring into the fish or miscellaneous fish.

2: Fang Miao: Do ​​not put the fish fry directly after the fish ponds. One must look at the weather. If the weather is good, if the weather is good, the temperature of the surface of the fish pond cannot be kept high. You can wait until the evening when you are stocked. If it has been a long time, then you must first stir the water. On the surface, let another person put the seedlings on the surface; and look at the wind direction: choose a tuyere or a half-uplet to put the seedlings (the lower tuyere, such as the flies, will be blown to the edge of the fish pond due to a small wind, and cause death); Depends on whether the temperature in the oxygen bag is the same as that in the fish pond (can not be too different, if the difference is too big, the oxygen bag is high, the temperature of the fish pond is at the end, let the oxygen bag in the cool place for about half an hour, until the temperature is almost the same So far, sunny days cannot be placed in fish ponds where solar energy shines. The reason is that due to the sun's rays, the temperature in oxygen bags will rise rapidly and the young fish will be killed by heat;

3: splash soy milk: Soak high-quality soybeans to the skin without wrinkles so far (to use natural water), with a refiner squeezed into milk, the first three days to an acre with about 4 kg of soybeans, after the fish pond water can be thin Appropriately increase or decrease a little.

Sprinkle when you want to evenly, be fine. It's a bit like the best style of rain. When people pour milk in the fish ponds, they should walk backwards, and the steps should be small; the whole pool should be spilled.

4: Buffy fish seedlings can grow to about 3 cm after 20 days to 25 days! At this point, it may be possible to capture or sell fish or fish ponds (too small to grow in size, and the specifications will vary in size)
