At what temperature does the herring stop?

In general, when the water temperature is lower than 10, herring will not open its mouth. The survival temperature of herring is 0℃~40℃, the optimum water temperature is 20℃~30℃, and the optimum temperature for catching herring is 25℃~40℃.

The PH value of the most comfortable water for herring is 7~8.5, that is, the weakly alkaline water quality is the best. The requirement of herring for dissolved oxygen in water is 3mg/L, which can generally be met in most ponds. To sum up, it is possible to catch a full bowl of herring according to the weather, temperature, pH of water and dissolved oxygen in water.

Living habits of herring

Black herring is not as active as grass carp, but it is much stronger than grass carp. Black herring is a carnivorous fish. Black herring takes mollusks at the bottom of the water as its main food source, and especially likes to eat snail meat, so black herring is also called snail green.

Black herring also eats clams, mussels, shrimps, dragonflies, larvae and water worms. In artificial fish farms, black herring naturally mainly uses granular plant bait artificially put in. Bran, bran powder, cooked sweet potato, bean powder, rice grains and grass are also bait for herring.

Black herring has different needs for food in different growth periods, such as young black herring, which mainly feeds on zooplankton; The larval stage mainly feeds on benthos, dragonfly larvae and chironomids. When fish grow up, people feed herring with silkworm chrysalis, corn, bean cake, bean dregs and fermented grains.
