Mixed culture of Pelteobagrus fulvidraco in adult fish ponds has no strict requirements for the main fish in ponds. Pelteobagrus fulvidraco can be mixed in fish ponds where four major fish are cultured and fish ponds where edible fish are mainly cultured.
2, parent fish pond polyculture
Mixed culture in parent fish ponds can not only make full use of the water space of parent fish ponds and improve the utilization rate of parent fish ponds, but also Pelteobagrus fulvidraco can eat some small wild fish that compete with parent fish for oxygen consumption.
3. Mixed culture in adult crab ponds
Mixed culture of Pelteobagrus fulvidraco in crab ponds can make full use of natural bait biological resources in crab ponds.
4. River and ditch polyculture
There are many low-value wild fish in the river ditch, and artificial bait can be saved by polyculture of Pelteobagrus fulvidraco.
5. Large-scale polyculture
The population yield of Pelteobagrus fulvidraco mixed culture in large water surface is high, which does not affect the yield of main cultured varieties and does not need additional feeding.
Extended data:
No matter what kind of polyculture is adopted, the following matters should be paid attention to in aquaculture management:
First, keep the water high in dissolved oxygen.
Second, maintain a reasonable stocking density and stocking specifications.
Third, the mixed culture of Pelteobagrus fulvidraco in fish ponds is no longer suitable for mixed culture of other carnivorous fish, nor for mixed culture of Pelteobagrus fulvidraco in freshwater shrimp and crayfish culture ponds.
4. If the specifications of Pelteobagrus fulvidraco are found to be too small in the process of culture, it means that the biomass of natural bait in the fish pond is insufficient, and small miscellaneous fish and shrimp, summer flowers of domestic fish or artificially prepared special bait for Pelteobagrus fulvidraco can be appropriately supplemented.
5. Mixed culture of Pelteobagrus fulvidraco in crab ponds, because the river crab and Pelteobagrus fulvidraco are in the same water layer, it is easy to cause niche competition between them.
