How to identify the quality of Loach seedlings

How to identify the quality of Loach seedlings? The quality of Misgurnus anguillicaudatus seedlings will directly affect the economic benefits of Misgurnus anguillicaudatus culture. In fact, the quality of Loach seedlings can be identified from the following aspects:

To understand the fertilization rate and hatching rate in the propagation of this batch of seedlings. In general, the fry with high fertilization rate and hatching rate have better physique. Using wild Loach to directly promote the hatching of Loach seedlings, the hatching rate is very low, the quality of Loach seedlings is not good. Therefore, the purchase of Loach spray seedlings depends on whether there is enough breeding for Loach. It is best not to buy the hatchery where the species of Loach is relatively rare or purely uses the wild Loach to induce the birth temporarily.

The body color is fresh and tender. The seedlings that are symmetrical, fat, uniform in size and active in spirit are good seedlings.

Fill a small amount of Loach seedlings in a white porcelain basin, blow the water surface moderately with the mouth, the strong swim against the wind and swim against the current; the weak are blown to the edge of the basin with the water waves, and if the strong ones are most, the Loach seedlings can be used for breeding.

Sheng seedlings in the white porcelain basin, after draining water, high-quality seedlings struggle violently at the bottom of the basin, the head and tail bend severely; the fish stick to the edge of the basin, the struggle is weak, or only twist the head and tail slightly.

Loach spray seedlings temporarily raised in the cage for too long, it will lose weight, physical decline, not suitable for long-distance transport. Suitable transportation of splash seedlings is 3-5 days after hatching, too late will reduce the survival rate of transport.
