How to prevent Loach from escaping

The "step" escape prevention method can be adopted, and the effect is very good. That is, build another step on the inner edge of the ridge. Wide 20cm, lower 15cm than the ridge of the field, Loach jump to the steps, it is difficult to jump up the ridge of the field, so as to achieve the purpose of escape prevention.

The anti-escape net can also be installed. Generally, the width of the anti-escape net is 1.8 meters. In order to make the anti-escape net erect and upright (the anti-escape net is as straight as possible, not close to the water embankment, so as not to be bitten by rats or squeezed by the waterproof dike), you should first drive piles, the distance between the pile and the pile is about 1-1.5 meters, dig a 60-70 cm ditch, bury the anti-escape net, and then fill the ditch. The soil used is collected nearby in the mud pool, but the pit can not be dug, it can only be flattened, and it can be prepared for catching Loach in the future.

The above is for reference only.
