Ramamurthy, S (1972) Observations on the prawn fishery of the Mangalore Estuary on the south-west coast of India. Indian Journal of Fisheries, 19 (1&2). pp. 143-155.
The estimated annual prawn landing varied from 1.09 to 5.S4 tonnes, the peak period of the fishery ^ bfia&. November-February. The fishery showed an inverse relationship to rainfall in ali''Q(g<;y||a£S except in 1965-66. The catch was mainly composed of Metapenaeus dobsoni, Penaeus indicus and M. monoceros in the order of their abundance. The modal size for M. dobsoni, exclusively caught by shore-seine, ranged from 31 to 40 mm. Differences were noticed in the size composition of P, indicus caught by different gears which were apparently related to the areas of operation. X^ analysis showed significant variations in the sex ratio of the juveniles of M. dobsoni especially during the latter part of the season. It has been pointed out that this is also likely to be a factor of influence on the pattern of sex distribution of adult sizes in the sea.
