First, when the squid is found to be pulling or floating, it is necessary to dissect the squid and check the gastrointestinal tract for judgment. There are two general conditions:
1. Anal swelling, intestinal congestion, indicating that bacteria caused by enteritis, need to take some drugs, such as norfloxacin, allicin or furazolidone for treatment, generally oral course of treatment for 5 days to 7 days. After oral administration of the above drugs, care should be taken to use the beneficial bacteria + vitamin C + Liwei San to treat the gastrointestinal tract for about 10 days.
2. If there is no congestion between the gastrointestinal tract and the anus, this is a case of climatic enteritis. Do not blindly use oral antibiotics in such cases. Such as micro-ecological preparations + vitamin C + Liwei scattered orally for 10 days.
Pay attention to determine the phenomenon of good enteritis, whether the treatment is correct will directly affect the level of aquaculture costs and the length of the breeding cycle.
Second, this year's Ou Miao basically entered the White Tsai with feed, in Fuqing, Yongtai, Yubei, Fujian and other places as early as the seedlings market has begun feeding white feed material, black feed, most of the market selection Feed the "Hippocampus brand" white litter. With the exception of a small number of pests and diseases, the rest of the market is ideal for using the "Hai Ma Brand" white material to reflect its viscoelasticity, palatability, and longevity. The quality of seedling cultivation will directly affect the number of three types of seedlings and the success rate of the year, and thus determine the cost per ton. In this case, there is a suggestion that the average day of feeding for white litter feed is from 10 days to 15 days. A short or long feeding period is not conducive to the cultivation of seedlings.
Thirdly, a number of bipolar bugs have been found in the field during the breeding of white seedlings. They have been severely infiltrated into the kidneys. The occurrence of bipolar diseases will cause a large increase in the number of three types of seedlings. Occurrence of bipolar worms generally does not cause a large number of squid deaths, so they are often overlooked by marketers. In addition, the bipolar worms are not easy to observe. Therefore, how to observe and treat the bipolar worms is the key to current salmon culture. The dipoles resemble olives with a small circle at both ends and resemble glasses. If parasitized in the kidney, the white-spot cysts can be seen by the naked eye. After we cut out the white spots and observe them with a microscope, we can find that there are bipolar shrimps.
The main methods of prevention and control are:
1. Oral administration of spore powder or chlorhexidine 5 grams per kilogram of material, and even served 10 days.
2. Oral administration of primaquine 5 tablets to 6 tablets, even for 5 days.
3. The medicated bath was treated with 5 mg of spore powder and 1.5 ppm of insecticidal agent.
