Department of Aquatic Environment Management

Introduction

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, 15 PG and 10 Ph.D. courses and till date 68 PG and 9 Ph.D. 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, Central Instrumentation 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. The department also provides different training programmes and webinar on “Field level water quality issues in the management of fish and shrimp farms and compost preparation using fish solid wastes.

Infrastructure

Central Instrumentation Lab

A Central Instrumentation Lab was established during March 2015, as a separate \ scheme under the Department of Aquatic Environment Management, for common benefit of PG and Ph.D students, to pursue their research work.

  • The facility was primarily established with the following objectives.
  • To create a common research facility for UG and PG students and also for staff research.
  • To pool up research infrastructure so as to strengthen research capability to maximize research output.
  • To facilitate inter-departmental research programmes, and avoid duplication of research establishment in different departments
  • To maintain all instruments in proper working condition, for better utilization.
  • This facility provides easy access to all staff and students to carry out their research work unhindered.
