Fish farming tips
First, a simple oxygen measurement method using a siphon pond to take 260 ml of water sample and inject into a 250 ml volumetric flask. Immediately fix the oxygen in water with 05 mg each of manganese sulfate and basic potassium iodide to make it flocculent to the middle and then use it. Concentrated sulfuric acid (density 184 g/cm3) 05 ml acidification of the precipitate, this time in accordance with the color of the fish pond water samples draw different color threshold oxygen value map for comparison, you can know the dissolved oxygen in water, the comparison is as follows: Brown, dissolved oxygen: 10 mg/l or more (high oxygen is favorable); brownish yellow, dissolved oxygen: 63-71 mg/l (safe and harmless); orange, dissolved oxygen: 44-51 mg/l ( (vigilance); pale yellow, dissolved oxygen: 15-21 mg / liter (hypoxia risk); gray or white, dissolved oxygen: 10 mg / liter or less (extremely dangerous). Second, how to add drugs in pellet feeds 1. For example, when the amount of drugs added is 15%, 150g of drugs and 30g of drug binders can be mixed first and then added to 1000ml (1kg) of clean water. Stir, stir and stand for 10 minutes. When the liquid becomes viscous, mix 10 kg of feed and dry the bait in the shade. 2. Precautions for use: (1) Drugs and drug adhesives must be dried to avoid moisture; (2) After the drugs and drug adhesives are mixed in a dry state, they are slowly added to water and stirred while stirring.
