AERATION SYSTEMS USED FOR THE OPERATION IN OPTIMAL PARAMETERS OF FISHING PONDS

The ecological conditions for fish development depends on certain water quality parameters, such as: dissolved oxygen, total ammonia-nitrogen ratio, total alkalinity, free C02, total hardness and planktonic life in the pond (Hepherand Pruginin, 1981; Ali eta I., 2000). Artificial aeration is a method that has a positive impact on pond productivity, thus increasing the growth and production offish at high storage densities, and the use of aeration equipment in aquaculture ponds depends on a very well-developed management (Perry L Oakes et al., 2011). In an intensive aquaculture system, increased fertilization, overfeeding and high storage density lead to insufficient natural aeration, and this may become a limiting factor for production. [...]a very good method is artificial aeration, being a beneficial alternative for the survival of flora and fauna, since it leads to a rapid and healthy growth of crop species (Tanveer et. al., 2018). Dissolved oxygen from aquaculture ponds is one of the most critical limiting parameters and is a very important factor in terms of water quality and underwater life, as aquatic organisms require a constant supply of oxygen to perform respiration and other biological activities, and food waste from water will be oxidized efficiently (Tanveer M., 2017).
