The growth of thick trees around the pond can block the passage of sunlight to the pond, resulting in death of plants and thus the animals. Besides this, natural succession can occur which can totally change the biotic community. It actually occurs due to the changes in the plants, animals or other a-biotic factors, and so a new eco cycle can beginNitrogen cycle affected: During transportation, ammonia is released in the atmosphere, which is absorbed in the pond. Fertilizers are highly harmful for the fishes as it contains nitrites and nitrates and thus can affect the nitrogen cycle. Ammonia is extremely toxic to fish and should be removed or converted into harmless matter. If the level of ammonia increases in the pond, fishes can die. New agricultural practices have highly disturbed the nitrogen cycle of the pond. In order to fulfill the agricultural demands for food, there is an extensive usage of nitrogen gas in the green house which enters the pond through different means.Carbon cycle affected: Accumulation of Carbon dioxide in the pond is highly dangerous for the fish species living in it. If the carbon dioxide amount is high in the pond, it would be difficult for the fishes to remove their internal carbon dioxide in the water, resulting in accumulation in fish blood. This inhibits and endangers the ability of hemoglobin in the fish blood, and thus causes suffocation for fishes.Bioaccumulation and Biomagnifications: Bioaccumulation can occur when human drain the contaminants in the pond. The contaminants entering the pound are absorbed in the tissues of species inhabited. This is highly dangerous and results in the accumulation of contaminants (mercury etc) over time. This happens when the species at the lower tropical level with contaminants are consumed by specie at a higher tropical level.Endocrine Disrupting Substances: People can pollute pond water with Endocrine disrupting substances (EDS), which are pollutants have the tendency to alter the growth, development and the reproduction of aquatic organisms. EDS are found highly in alkylphenolics (detergents used to remove oils), agricultural pesticides etc. If consumed by fish, can destroy fish embryo and damage fish reproduction organs.Michigan University extensions wrote a paper on pond management, according to which, many local runoffs are diverted and kept away
