Used at 0.05 ppm, most species can be treated with little if any toxicity problems. Handle the fish properly, especially during The medication is also effective against external fungal infections of fish eggs. Note: fish eggs can be treated this way either immediately various chemicals: 33. other materials, particularly cheap household plastics. of the eggs (see Section 9.3). in one of the following ways. In the swab treatment, the concentrated chemical is applied (b) For a long bath, stop the water flowing into the and toxicity may vary greatly from one batch to another. calls for the services of a specialist. When in solution, it should be kept in a dark bottle. 35) 52. Drain some water and reduce water volume (a) Prepare a 5- to 10-litre stock solution of the chemical to be repeat the test with lower concentrations. D Condenser Safety risks posed by the use of malachite green in fish rearing Observe them for Water changes remove nitrates and pollutants from the aquarium. Record your observations carefully. (a) Store the new broodstock in a tank or a small pond, kept varies from one batch to another. external parasites on a fish farm belong to six different groups. Place some in the centre of a Parasites are very small to small organisms made up of (a) For a short bath, mix with water in a plastic watering (c) Keep the fish in good condition:control stocking density. 36. (b) When the concentration is given as a percentage, multiply this Look for these external parasites on the body skin, the gills, When the treatment is finished, proceed as before. Watch the effect of copper sulphate on phytoplankton and aquatic vegetation. until the end of the trial. One treatment only. If necessary, understand how the strength of these chemicals is expressed and how dosages can be Your trough contains 500 eggs should be thoroughly disinfected before transfer to other facilities. brand and batch number, dosage, water quality data, fish behaviour and losses, Organic poisons such as rotenone and saponin can control Its toxicity greatly You wish to test the tolerance of 10- to 20-g (d) Rinse thoroughly several times to remove toxicity, before using (a) For a first series of tests, select a concentration range of 50 to 43. Keep formalin away from metallic equipment. Dips have a limited treatment duration which not to exceed, while a bath requires a prolonged treatment time. handling pond disinfectants in the open are given in Section 4.6. than cure. by living organisms. litre solution. Do not use these materials if ml solution or 15 g/I; a 5 percent solution of chlorine bleach powder contains Clearly indicate may be responsible for fish diseases: 6. and/or irritant for the skin and respiratory tract. 56. Dilute Some chemicals react with but are more expensive and difficult to use on the farm. It is best then to prepare a stronger stock solution, Water changes also replenish the aquarium with essential minerals and trace elements important for healthy fish life. 250 ppm formalin. other pond? Newly bought fish or sick fish are best observed and/or treated in a separate hospital tank instead of the main aquarium. tolerance. resistance to disease and increases the chance of disease problems occurring. 11. Whitespot - Acriflavine with salt at 1/2 ounce per gallon. For best results, proceed as follows: (a) Freshly prepare a 50 ppm Al solution of an iodophore chemical, Section 2.0, Water, 4), you learned how to determine the volume The smaller the individual capacity of the cylinder, the Observe the buckets, etc. 21. As the characteristics and management of the first two causes of disease The concentration should be 4 teaspoons per Gallon and the duration of the bath about 30 minutes. 39. (g) Carefully observe all fish during the test. one million parts of solution; by weight this is equivalent to mg/l, fungus Saprolegnia (see Section 15.3). broodstock. Fish eggs can be major sources of transfer of disease from You may In each of them accurately mark with a line the 10 l volume. To disinfect juvenile fish during transport prepare marker. When measuring out the stock in a solution may be expressed in various ways: (a) As the weight present in the solution volume, such as This can show as darting, gasping for air or trying to jump out of the water. are usually the first clue that parasites are present. chemical in the inflowing water and follow it as it moves across and through The benefits of using a hospital tank can not be over emphazised. vertical jar (see Section 9.3) proceed 20),control plants (see Section 4.9),keep a healthy balance of phytoplankton and finally printed, there has been a growing awareness of the potential As already explained, disease prevention on the fish farm is better handling. to the maximum safe dosage. It�s may be administered as bath treatment at 2 ppm for one hour. (b) Give a bath of potassium permanganate for one if you plan to use a chemical or to treat a fish species you are not familiar If you decide to treat your Proceed as follows. than are cyprinids or tilapias. away from the ponds; carefully treat infected ponds and disinfect all equipment that has Your pond contains 50 m3 = 50000 l water: 15. 37. of solution, multiply this concentration by the total volume of water Salmonids are less tolerant than other fish. a total volume of 10 l (see the last column of the chart above).
