View the PDF document Fishing pressure on the resource of the elongated giant clam, Tridacna maxima, in Tonga (In Fisheries Research Bulletin of Tonga, Volume 3, 1995)
Author(s): Kava, V., Udagawa, K., Ikenoue, H.
Publisher: Ministry of Fisheries, Tonga
Place: Nuku'alofa (Tonga)
Notes: pp. 11-17
ASFA Keywords: Clam fisheries, Fishery statistics, Fishery data, Fishery management
Country Collection: Tonga
Abstract: The size distribution of T. maxima landed at Vuna Wharf fish market indicated that the stock of T. maxima was subjected to stronger fishing pressure in 1992-94 than in 1979. The stock of clams larger than 100mm SL has decreased to such a low level that the catch of larger clams cannot be increased by intensifying fising effort.
