Prevention and treatment of fish diseases in cold seasons
Will not make attention. When the spring water temperature rises, rapidly developing into acute epidemics, causing many deaths. Disinfected to prevent the disease should improve the pond, fish pond before the next salt diffuse wash with 5 3-5 minutes after the pool under the concentration regularly lppm 20ppm bleach or lime Quanchiposa, prevention and treatment effects are good. 2. Fungal fish diseases: a Shuimei Bing. Mechanical damage, frostbite, or over-intensive care in the winter and spring types of fish most susceptible to the disease, causing death after another. Potassium permanganate solution with 20ppm immersion disease species, prevention is better. Available when gall disease (a type of traditional Chinese medicine) Jianzhi Quanchiposa treatment, medication concentration of 2ppm. 3. Fish diseases caused by protozoa: the main port of filariasis and echinococcosis inclined tube. The two fish diseases in the area of small, dirty water ponds most likely to occur, suitable temperature onset of 12-20 �� ,8-11 �� still a lot of time there. Density, poor health of the species in the near future a large number of infections can cause death. In addition to doing a good job of ponds and fish disease disinfection, 07ppm available before and after the spread of fish disease, between the dorsal and anal fins at the surface were tested as well as white. Finally diseased fish head down, tail up, with the water perpendicular to the near dead. 2. And effect of treatment with lOppm bleach dip, dip one day, 3 times effective. 'Five, skin abrasions, if the mistake (and tied box of friction) causing fish table (mainly snout) mechanical damage. 1O per treatment and 80 million liters of water immersion species of penicillin for 5 minutes every other day, 2 or 3 times the effect. Copper sulfate and ferrous sulfate (5; 2) units or single-agent use o. 8ppm of copper sulfate to prevent Quanchiposa lift. 4. Fish disease caused by crustaceans; mainly pediculosis. Favorite winter species cluster, pediculosis extremely popular,[link widoczny dla zalogowanych], resulting in fish thin, poor body, affecting growth; lice bite open the door to bacterial invasion. Periodic crystal with 90 trichlorfon concentration of 0.2 ~ 0.5ppm throwing aside, you can kill all. 5. Non-parasitic fish diseases: lack of food caused mainly by the deflated wilt disease. Cold season, many people think the habit of starved fish, in fact, most of the time cold season, or a small amount of fish feeding, long-term investment and not feed fish to maintain their basic metabolism and nutrition after excessive consumption of their own will the disease occurs. The disease occurs, the fish physical range of the spring breeding sub-pool will cause a lot of fishing mortality, and disease take a very long time to recover,[link widoczny dla zalogowanych], seriously affecting the growth and development, but also susceptible to suffering from various diseases. The best way to prevent disease is to strengthen the feed management, keep food in winter and spring (but can be less investment), and wintering species pool and even more so. Luoma fish market Suqian City Code 223808 Lau Yiu feeding the fish you have to buy However, the blood meal to feed the fish homemade poorly,[link widoczny dla zalogowanych], Harada is the absorption rate is too low, that most of the excreted protein in vitro myeloid and wasted. To solve this problem, our research scientists shed a amino acid, thus greatly improving the utilization of blood meal. According to our determination of blood meal in the fermentation of various amino acids can be absorbed the ancient protein accounted for 85% or more. In addition,[link widoczny dla zalogowanych], the fermentation process,[link widoczny dla zalogowanych], the addition of the vegetable protein source ingredients such as wheat bran, so that more homogeneous barrier kinds of amino acids, also increased the diet of vitamins, particularly vitamin B content of more than a general source of animal protein. We replace most of the fermented blood meal into the I: 1 sperm Roof feed on carp with grass carp, leather and river catfish Catfish have achieved satisfactory results.
