In terms of farming techniques, especially in black pits, attracting herring into dens is a critical step. First of all, we need to understand the habits and preferences of herring. Herring usually prefer to be active in quiet waters and prefer to feed on the bottom, so it is important to choose a deep water area suitable for herring to inhabit as a den. In addition, to attract herring, we can use some food as bait, such as small shrimp, earthworms, etc. These foods can give off a strong flavor that attracts herring to feed.
When rearing herring in black pits, we also need to pay attention to water quality and the environment. Keeping the water fresh and the right amount of oxygen is key to attracting herring. At the same time, proper adjustment of water temperature and pH can also help herring better adapt to the environment. In addition, it is also necessary to avoid overfeeding and contamination, as this can affect the water quality and the health of the herring.
In order to better attract herring into the den, we can also use some special tricks. For example, we can use the sounds that herring likes to attract them. For example, striking a metal object, using a sonar device, or a herring favorite sound can all be tried. In addition, we can also use lures of the color and shape that the herring likes to attract them.
In conclusion, to attract herring into the den, we need to understand the habits and preferences of herring, maintain proper water quality and environment, and use some special techniques to attract them. Through continuous practice and adjustment, we can gradually master the breeding skills and improve the efficiency of herring farming in the black pit.
