Abstract

The occurrence of commercially important groupers in high percentages in the nursery ground near Vellapatti, North of Tuticorin in Gulf of Mannar Coast reveals the resources of the spices for collection and scope for farming. Epirrephelrts In~~vintdro minates the catches of mini-shore-seine, popularly known as 'Ola-valai'. The peak season for the collection of young ones in the size range 70 - 200 lnln is October - January, though it is observed round the year. The estimated catch, effort, species composition and size distribution are presented in the paper. The monthly catch of this valuable species is estimated to be 15,000. The techniques employed in the collection of adult, matured size specimens of the size range 530 - 850 mm, weighing 2 - 12 kg are described. The feeding strategy and conditioning of the collected specimens in holding tanks/ cages are discussed. The technology evolved for the transportation of young specimens as well as broodstocks to different culture sites are highlighted. The present observations reveal the scope for large scale farming of groupers in cages and coastal ponds as well as to promote the export trades of live specimens.
