Abstract
The study on sustainable management of fisheries was taken up in the Cuddalore district of Tamil Nadu with varying
levels of pollution by SIPCOT industries. The cost of fish production was highest for low affected category due to less pollution
intensity and the consequent high fish production in that category. The gross income and net income was highest for low affected
fishermen with Rs. 468816 and Rs. 151237 respectively which showed that they were more profitable than other two categories. Fish
catch was varied with pollution intensity.
Resource use efficiency of fish production with Cobb-Douglas production function revealed that variables of fuel cost, number of
fishermen and maintenance cost were positive and significant for all categories of fishermen. The technical efficiency of affected
fishermen with Data Envelopment Analysis revealed that mean technical efficiency and scale efficiency of the three categories of
serious affected, medium affected and low affected fishermen was similar and was around 99 per cent. The Contingent Valuation
revealed that the WTP amount was also highest for serious affected category with annual amount of Rs. 5850 and higher over
medium affected category by 163.59 per cent and over low affected category by 491.18 per cent. Sustainable Rural Livelihood
framework analyses showed that low affected fishermen was more sustainable followed by medium and low affected fishermen.

Introduction
Tamil Nadu ranked fourth in marine production in
India. Tamil Nadu with its 1076 km of coastline, 1.90
lakh sq.km of Exclusive Economic Zone (EEZ) and a
continental shelf of about 41412 Sq km is one of the
leading producers of both marine and inland fish and
fish products. The marine fish potential in Tamil Nadu
estimated at 7 lakh metric tonnes. The fishing
population in the state is 9.15 lakh fishermen and of
which, 2.60 lakh are actively engaged in fishing.
In Cuddalore district, the chemical industries are
located in the SIPCOT industrial complex. There are
12 major industries covering an area of 516 acres are
very close to the sea coast. These industries polluted
the ground and surface water and also impacted the
availability of fishes. Also, modern shrimp farms have
replaced the coconut gardens and mango orchards and
also affected fish production. Further, the coastal
ecosystem is turned into hotspot for real estate
activities with the development of farm houses like
Happy Bay, Sea Breeze and Vishwamudra. In this
juncture, the sustainable approach to fisheries
management requires at the foremost the analyses of
production efficiency and technical efficiency of
fisheries production. It requires then the conservation
of fisheries resources, which one would realize
through the valuation of fisheries damage using
market and non-market valuation methodologies. It
finally requires the estimation of sustainability
through approaches like Sustainable Rural Livelihood
approach (SRL).
1 Methodology
In Cuddalore district, among the fishing villages
affected by SIPCOT industries, six fishing villages
were selected purposively to study the negative
externalities. Based on the intensity of pollution, they
were categorized into seriously affected, medium
affected and low affected. A sample of 20 fishermen in
each village was selected randomly and the sample
size was 120. Production efficiency analyses were
