Temperature changes cause water quality changes, how to do a good job in fish pond management work in May

 

Fish pond 

 

    In May, air temperatures rise, fish feeding increases and growth speeds up, but the climate is unpredictable, water quality changes easily and diseases break out and spread, making it a month that requires special attention in fish pond farming. The main points to pay attention to are the following:


    First, pay attention to fertilizing and feeding.For ponds mainly raising filter-feeding fish, topdressing fertilizer should be applied in good time according to water color and transparency. For ponds mainly raising feeding fish, feed should be provided in good time.


    Second, pay attention to increasing oxygen and changing water.In May, fish feeding increases, excrement increases, and water quality easily deteriorates and becomes oxygen-deficient. So every day, according to weather conditions and water quality conditions, use aerators in good time to increase oxygen. Especially during showers and muggy weather. At the same time, add new water, raise the water level, and replace part of the bottom water. Apply beneficial microbial preparations (photosynthetic bacteria, EM bacteria, etc.) once every 15 days, splashing evenly over the whole pond, to decompose organic matter in the pond, reduce harmful substances, inhibit the reproduction of pathogens, and keep water quality good.


    Third, pay attention to disease prevention.Because the water temperature is suitable at this time, various pathogens breed and multiply, and fish are very prone to disease, but proper prevention can effectively reduce economic losses. The types of diseases that easily break out at this time include saprolegniasis, skin rot disease, branchiomycosis, enteritis disease, hemorrhage disease, ichthyophthiriasis, trichodiniasis, etc. The key work to do well is preventing bacterial and parasitic diseases. The method is to regularly use quicklime, chlorine dioxide, dibromohydantoin or microbial preparations, etc., splashed to disinfect and improve water quality.
