Use of chemicals in aquaculture in Andhra Pradesh

The importance of aquaculture to the socio-economic growth of a state cannot be over emphasised. It increases the production of animal protein to meet the needs of a fast growing population. However development of aquaculture is well known to be the major contributor to the increasing level of organic waste and toxic chemicals in the aquaculture industry. Apart from this intensive aquaculture carry high risks of serious aquatic disease outbreaks because it has greater needs for water treatment chemicals and drugs for disease prophylaxis and treatment. Any misuse of these chemicals and drugs could have serious environmental consequences to adjacent waters and may lead to the development of resistant strains of human pathogens. This paper focuses on the environmental impact of chemicals such as chemical fertilisers, chemical in feed, antibiotics, anti-fungal agents, agro-chemicals and industrial pollutants that are used in aquaculture industry of Andhra Pradesh due to intensive shrimp farming and pisiculture in the coastal region of Andhra Pradesh. The paucity of information regarding the health hazards and risks associated with the use of hormones, feed additives, anaesthetics, veterinary drugs and vaccines in Andhra Pradesh and most of the other states and the need to intensify investigations to generate data for the development of quality criteria and legislative frame work for adequate use of chemicals in aquaculture were stressed. The chemical health concerns associated with products from aquaculture and the possible risks to consumers are discussed in this paper. The need for rational use of chemicals in aquaculture was stressed. Therefore, it is apparent that appropriate waste treatment processes are needed for sustaining aquaculture development.
