Department of Aquatic Environment Management


The Department of Fisheries Environment was established at Fisheries College and Research Institute, Thoothukudi by Tamil Nadu Agricultural University (TNAU) in 1977. The department was established with the aim of offering professional education on the aquatic environment, conducting pollution monitoring studies and extending fisheries knowledge to the farming and fishing communities. The major thrust areas of research focuses on pollution monitoring studies in Gulf of Mannar, bioremediation of effluents from aquaculture systems, seafood processing plants, development of soil probiotics in fish/shrimp culture systems, screening and monitoring of occurrence of harmful algal blooms and stranding of mammals in Gulf of Mannar, hydrobiology and biodiversity of inland and coastal waters of Tamil Nadu. Current research programmes in the department are in the fields of utilization of fish waste and drifted seaweeds as fertilizer for Agriculture, water quality management aspects in Penaeus vannamei culture systems and monitoring of pesticide residues in Thamirabharani river belts.

This department offers 7 UG, 12 PG and 10 Ph.D. courses and till date 51 PG students have graduated. The department has successfully developed 3 technologies viz., cost effective white worm (Enchytraeus albidus) production as live food for ornamental fish, vermi composting of seafood processing plant sludge, rapid composting of sea food waste using sugarcane bagasse and transferred to the farming community by conducting several training programmes. Since January 2017, this department has been renamed as Department of Aquatic Environment Management as per the ICAR nomenclature. The department has various lab facilities like UG laboratory, PG laboratory, Algal culture Unit, Environmental Microbiology laboratory and fish compost yard.

The department periodically receives samples from farmers of various districts of the state to understand the prospects of establishing a farm or learn problems in water quality and at times due to sudden mass mortality of cultured fishes/shrimps. The department provides advisory services to the fish, shrimp and ornamental farmers and entrepreneurs, related to soil and water management. The State Fisheries Department also approaches this department with local problems related to mass fish kills in public water bodies.
