What should be noted in mandarin fish farming? Water quality regulation and stocking density are key
Abstract During mandarin fish farming, attention should be paid to water quality regulation and stocking density, and filter-feeding fish can be polycultured to maintain the energy cycle of the pond. Fry are easily damaged during transport, so cultivating seedlings yourself can ensure the survival rate. Pesticides should be used rationally to reduce stimulation

Is the mandarin fish easy to raise in winter? Reduce stocking density and build a wintering pond before overwintering
Abstract The mandarin fish is not very easy to raise in winter, because the optimal water temperature for mandarin fish growth is around 20°C, and the lower winter temperatures affect its growth. Therefore, a wintering pond needs to be built, and pond consolidation should be carried out on sunny days when the water temperature is above 10°C. Before overwintering, stocking should be sparse and the water deep, reducing stocking density.

What are the precautions for mandarin fish farming in autumn
As autumn approaches, mandarin fish farmers should pay attention, so what are the precautions for farming mandarin fish in autumn? Below we introduce them for you.

Experience Sharing on Rotational Culture of Giant Freshwater Prawn and Mandarin Fish
Macrobrachium rosenbergii is not tolerant of low temperatures. In late autumn and early winter, when the water temperature drops to 15°C, the pond must be drained and the prawns harvested for market in a timely manner. In this way, the Macrobrachium rosenbergii culture pond is actually only utilized for half a year (May to October). Mandarin fish do not completely stop feeding in winter and continue to grow, only with reduced feeding intensity and growth rate.

Experience and Methods for Polyculture of Mandarin Fish in Adult Fish Ponds
1. Pond conditions. Adult fish ponds mainly stocked with bottom-feeding fish are generally 5-10 mu in area, while ponds mainly stocked with upper-layer filter-feeding fish are generally 10-20 mu in area, with a water depth of 2-3 m. Pond sediment should be relatively low, and there should be a complete water inlet and drainage system and equipment.
