To raise shrimp well, water quality management and scientific feeding are key

Shrimp farming is an important category of aquaculture, referring to the production activity of raising shrimp fry to marketable size through artificial control of the water environment. According to the farming water body, it can be divided into modes such as marine shrimp farming, freshwater shrimp farming, and rice-field shrimp farming, which are suitable both for large-scale pond operations and for small-area ponds or courtyard pools.

There are quite a few common farmed species. In marine water, whiteleg shrimp (Litopenaeus vannamei) and black tiger shrimp (Penaeus monodon) are relatively common, while in freshwater there are giant river prawn (Macrobrachium rosenbergii) and oriental river prawn (Macrobrachium nipponense); in recent years, red swamp crayfish farming has also been very popular. When choosing a species, it is generally necessary to take into account local water temperature, salinity conditions, and market conditions; for example, whiteleg shrimp has strong adaptability and grows quickly, making it the main farming target in many regions.

The core of shrimp farming lies in managing water. Dissolved oxygen, ammonia nitrogen, nitrite, and pH value in the water body are directly related to the shrimp survival rate. In daily management, it is necessary to persist in changing water, increasing oxygen, and regulating the algal phase. When the weather changes abruptly, it is even more important to turn on the aerators in time to prevent shrimp from gasping at the surface due to oxygen deficiency. For feeding, the emphasis is on small amounts given many times, with the amount preferably being what the shrimp can finish in a relatively short time, so as to avoid leftover feed spoiling the water quality. During the molting period, the feeding amount should also be appropriately reduced.

Disease prevention and control also cannot be ignored. Thorough pond clearing and disinfection before stocking, purchasing healthy and active shrimp fry, and regularly improving the pond bottom and regulating water during the farming process are basic practices for reducing common problems such as white spot syndrome and vibriosis. Overall, shrimp farming is a meticulous job. Only by doing a solid job in the links of water quality, fry, feed, and disease prevention is it easier to obtain a stable harvest.
