Quotas for the 1992-1993 geoduck clam fisheries / by R. Harbo, G. Thomas and K. Hobbs.: Fs97-4/2179E-PDF

"The geoduck clam fishery is managed by setting area quotas which are then equally divided for 55 Individual Vessel Quotas. The coast is divided into three licence areas: north coast, southern inside waters and the west coast of Vancouver Island. A three year rotation of fishing areas was also implemented in 1989, with the I.Q. program to reduce the annual number of landing ports. It appears that the total harvest to date exceeds the current estimates of stock and production. This has been compensated in 1992 and 1993 by closures and quota reductions. Due to stock uncertainties, industry agreed to reduce the quotas but on the basis of a two year plan being set so that the industry could plan their fishery and market the product. Reductions of annual quotas by 15% each season for 1992 and 1993 were accepted by industry in 1991. A licence will be moved each year from the west coast of Vancouver Island to the north coast. Over the period, 1992-1993 a scientific review of quota options is recommended prior to determining the 1994 quota. To determine the 1992-1993 quota options, the hectares of known commercial fishing areas were calculated (1-631 ha) and original densities were estimated as 1 geoduck/m² for southern inside waters, 2 geoducks/m² for the west coast of Vancouver Island and higher densities of 3.5 geoducks/m² for beds in the north coast. Yield options of 1% were recommended for all areas in 1992 and 1993. There is a great uncertainty as to the stock size of subtidal geoduck clams"--Abstract, page viii.
