Description Reefs were constructed mostly in the sandy region at a depth varying from 5 to 27m. Granite stones of varying sizes were put first on the site selected for the reef construction so as to form a circular or rectangular ridge. Eventhough fishing was done throughout the year in the neighbouring areas, in the reef environment, it is done only during the calm season between November and April. Tthe landing during 1987-'88 from the reef environment was only 59.0 tonnes. A drastic reduction in the landing from the reef environment could be noted during the subsequent year, ie., 1988-'89, with a total of 24.2 tonnes. The percentage contribution of fishes from the artificial reef environment dwindled to 3.6 from 8.5. Fishes like Decapterus dayi, Carangoides plagiotaenia, Priacanthus hamrur, Sphyraena sp. Rastrelliger kanagurta and Nemipterus spp. dominated the catch of the reef region. From the present study the general
guidelines for the placement of artificial reefs are suggested.
