In addition to the important factors affecting the result of the crop is the quality of seed, tiger shrimp farmers need to consider many other factors.
The environment has a very important meaning in shrimp farming, making a lot of decisions on the success or failure of the crop. Therefore, in the process of raising, farmers should pay attention to good management of environmental factors by stabilizing the water environment in the pond, managing water color, salinity, temperature, oxygen … Farmers should pay attention to ensuring ensure these parameters are in the most appropriate threshold, such as algae density, keep stable throughout the culture period. When it rains, apply lime on the pond bank and apply directly to the pond to limit the pH change. In addition, it is necessary to avoid changing the pond water environment. When using chemicals to treat shrimp pond water, attention must be paid to detoxification for shrimp.
Good management of disease will help ensure a successful crop. During the culture process, shrimp can be infected by many factors such as weather changes, adverse environmental factors, toxins of toxic algae, parasites, bacteria, viruses or by nutritional factors. , such as poor feed quality, vitamin deficiency … When the disease occurs, it should be handled thoroughly and responsibly, immediately informing the agency concerned about the disease to handle it promptly and properly. For finished ponds, wastewater and solid waste must be pumped into separate areas for sludge and waste storage; wastewater must be treated before being discharged naturally, limiting the spread of pathogens, monitoring the health of farmed shrimp …
Food for shrimps
The cost of feed in shrimp farming usually accounts for 50% of the total investment cost and feed management still needs to be improved. The cost of feed in shrimp farming has an important influence on the whole farming process. While raising, only use high quality feed, feed shrimp properly, do not use expired food or mold. In the diet of shrimp, it is necessary to regularly or periodically supplement Vitamin C, minerals, digestive enzymes … to enhance the resistance of shrimps. The best solution, should feed shrimp according to needs, help shrimp grow healthy, reduce worries for farmers.
Investing in the infrastructure system will help shrimp farming be convenient; limit risks and epidemics; maintain productivity and quality. Currently many businesses and farmers have invested in filtering technology. Filtering by biotechnology to convert NH3, NO2, CO2 … into non-toxic form. During the rearing process, water will circulate in a closed system and not completely change water, only a small amount of new water is added to the system to compensate for water loss due to evaporation. The amount of water supplied depends on the use of a partial or complete water system. In addition, businesses and shrimp farmers have applied modern farming models (cultured according to Biofloc, Semifloc technology, greenhouses …), minimizing the impact of environmental factors.
