Feed management: The key to successful shrimp farming

In addition to shrimp factors of premature death due to liver disease, pancreatitis, the food supply is a cause detrimental to shrimp, leading to crop failed as expected. Therefore, the management of animal feed must be the top priority, especially during the current epidemic.

Shrimp feed must be provided from the company reputable, proven quality and breeding success over the years. The transportation of food from agents to farmers may occur scrapes, peck bag or damp will inevitably reduce the quality and harm the health of farmed shrimp.

The appropriate feed management is an important factor for successful crop.

Du To Sua, Hoa Trung Village , Tran Luong commune, Cai Nuoc district, Ca Mau province, said: "Recently I used 15 bags of food plots with the phenomenon as drying, no smell and shrimp eat for 10 days, the phenomenon of edge rush shrimp. To the early harvest list ".

Regarding the process of breeding, rearing techniques, he said milk when feeding excess water about 3 Election to blackish green algae. Meanwhile, a number of cases handled by the algae crop chemicals to limit algal blooms, and micro-processing, mixing medicines, mineral hooked to enhance the health of shrimp, stable environment pond. These measures are very expensive and only effective in the short period that does not stabilize until the end of the crop.

Master Do Van Hoang, Aquatic Research Institute of Ming Hai, said: "There are many types of protein food companies are announced, but the shrimp absorb the proteins are easily digested axitamin remaining shrimp absorbed by the discharge external environment ".

According to Master Do Van Hoang, from the results of the research materials scientists, shrimp absorb only about 17% protein in the diet. Depending on the health of shrimp in different times and depending on protein content (axitamin) digestion of food that the shrimp can absorb varies during the day. Besides, current inspection and quality control of food - protein content in food companies announced on food packaging is very difficult.

Shrimp protein is discharged daily with food protein directly from the farmers feeding excess buildup on the bottom of the pond. After a while, this protein decomposition, generate toxic gases NH3 and H2S. Poisonous gases are handled by farmers fisheries drugs and must periodically to stable but very expensive. Along with direct excess nitrogen causes algae blooms and algae remains will be brought to shrimp shrimp cause respiratory difficulties, leading to mortality bottom, farmers harvested early in the period 1-2 months of age as the past.

Therefore, for successful crop, farmers must use microbiological quality of processed bottom periodicals; to management, feeding under the motto from enough to lower the amount of shrimp feed on each feeding. Must be based on the current weight of shrimp and prawn farming amounts to determine the amount of food for each meal. If done well managing the cost of food on the crop will reduce and reduce risk, help higher crop success ...
