Reasonable nesting In general, there are more wild fish in adult fish ponds. They compete for food and oxygen with the main fish. In this case, if the fertile fish with higher economic value are properly set in the intensive culture pool, the wild fish in the pond can be eliminated, and the economic benefits of the fish pond can be further improved.
Fish farming does not follow the trend When selecting aquaculture species, do not look at glutinous rice varieties to make money to raise oysters. Determine cultivars according to the overall market conditions and culture structure.
Emphasis on new technologies will give priority to new aquaculture species with high market demand and high technological content.
In the present pond intensive culture mode, the feed cost accounts for about 80% of the entire production cost. When the main herbivorous fish is mainly raised, some grasses can be used in the diet, which can reduce the cost of cultivation. Can also improve the feeding structure of fish to achieve the purpose of promoting growth.
Large-scale stocking For some cultured species (such as grass carp, head bream, squid, etc.), large-scale fish species can be invested to increase the outlet size.
The more carefully selected feedstuffs, the more they must use high-quality feeds in the case of sluggish breeding conditions. Otherwise, the fish's constitution will decline and the disease will occur more frequently.
