Description The fisheries service provided by an artificial reef (AR) with a pile size of 450
m3 deployed at 20 m depth off Chinnandikuppam, 20 km south of Chennai was
assessed. In 16 months, the fishermen expended 3843.7 hours of hooks & line
fishing in the AR ground and landed 6404 kg. The catch index was 14.2 kg/m3
and the total income was Rs. 2,74,000. Compared with the income per hour of
operation of gillnet fishing in the non-AR grounds (Rs. 52.5 kg/h), the income
was 36% higher from hooks & line fishing in the AR ground (Rs. 71.3 kg/h).
This was possible due to aggregation of high quality fish such as the snappers,
emperor and carangids in the AR. Biological investigations on three resident
species in the AR show that juvenile fish colonise in the initial months after
deployment, grow to a larger size and spawn in the AR, indicating the service
provided by the AR for enhancement of resident fish stocks.
