In the afternoon of June 8th, many people in Zhapu and Longhai in Zhangzhou City suspected eating poisoned mussels and experienced symptoms of dizziness and limb paralysis. Among them, according to the Xupu County Government, as of June 10, 62 villagers had been sent to hospitals at city and county levels. At present, several villagers have been discharged and the remaining patients are in stable condition. Mussels, also known as mussels, are called mussels and are bivalve molluscs. They are dark brown and live on rocks on the seashore. Fresh mussels are popular seafood products. It can be steamed and cooked, or it can be mixed and fried with other vegetables. Due to the large volume of mussels, it is not easy to preserve them after harvest and has been processed into dried products - mussels. Mussels have high nutritional value and have some medicinal value. According to the analysis, each shellfish shellfish contains 10.8 grams of protein, 2.4 grams of sugar, 2.4 grams of ash, and 1.4 grams of fat. The protein content of dried mussel meat is as high as 59.3%. Mussels also contain a variety of vitamins and human essential manganese, zinc, selenium, iodine and other trace elements. It is worth mentioning that the nutritional value of mussels is high because of the 8 essential Amino Acids such as valine and leucine required by the human body. The content of mussels is much higher than that of eggs and chickens, ducks, fish and shrimps. And meat and other essential amino acid content. According to another study, mussel fat also contains essential fatty acids in the human body. Its saturated fatty acid content is lower than foods such as pork, beef, lamb, and milk, and the content of unsaturated fatty acids is relatively high. On June 9, the Department of Oceanic and Fisheries of the Province initiated a second-level emergency response to red tides in response to suspected poisoning of mussels, and requested Quanzhou to initiate a three-level emergency response to red tides, immediately close the aquaculture production area in the red tide, and strengthen the control and control of fishing boats. Suspend fishing operations for aquatic products, strengthen inspections, and strictly prohibit the listing of aquatic products in the waters surrounding red tides. What is red tide? Red tide is a natural phenomenon. It refers to the general term of an ecological anomaly caused by some tiny planktonic algae, protozoa or bacteria in the ocean, which are fulminated (proliferated) or highly aggregated under certain conditions. As the temperature, wind, tide and other environmental factors in the sea area change, red tides will naturally disappear. In fact, red tide is not always red and red, it is the collective name of various color waves. In addition to the most common red color, there are pink, brown, khaki, beige, green, white and so on. Red tide is divided into non-toxic red tide and toxic red tide. Non-toxic red tides are generally harmless, and many of Hong Kong's famous “blue tears†landscape is actually a kind of red tide generated by noctiluca. Red tide organisms in poisonous red tides can secrete paralytic shellfish poisons, pelagic shellfish poisons, and neurotoxic shellfish poisons. Once eaten, humans can easily cause poisoning reactions. How to prevent after occurrence of red tide The general public friends, after knowing that there is a red tide in the relevant sea area, do not go to the sea for fishing and other activities, and do not eat seafood from the vicinity of Red Tide. Once ingested, it is found that the lips, mouth, and tongue are abnormal and numb. The needles and toes often have acupuncture-like pain. When accompanied by headaches and dizziness, they should seek medical attention. Of course, aquatic products caught from normal sea areas can still be eaten with confidence. Aquaculture farmers, when red tides occur in the aquaculture sea area, may adopt measures such as transfer, subsidence, isolation, and recovery of relevant sea aquaculture cages to reduce the damage of red tide organisms to marine aquaculture. The nursery and breeding farms located at the source of seawater intake in the Red Tide area should close water intakes to avoid losses caused by water pollution. Amino Acids Amino acid additives are used in feed to balance or supplement a particular production purpose of the required nutrients. The main amino acids added in the feed are: lysine, tryptophan, methionine, threonine these limiting amino acids. Amino acids are the basic building blocks of proteins. The essence of protein nutrition is amino acid nutrition. The core of amino acid nutrition is the balance between amino acids.
The balance of amino acids in natural feed is very poor. Almost all of them are not balanced. The animal body in the limited feed can not synthesize themselves.
They can only rely on eating intake of amino acids. The amino acid content of natural feed is very different, each is not the same, because of different kinds, different ratio of natural feed composed of full price compound feed, although try to mix according to the principle of amino acid balance, but their various amino acid content and the proportion between amino acid is still variable, various. Therefore, amino acid additives are needed to balance or supplement the requirements for a particular production purpose.
