Recreational clam harvest survey - 1984 / by N. Bourne, R.A. Carmichael and B. Bishop-Lowen. : Fs97-6/1570E-PDF

"Results of a 1984 survey to assess the recreational intertidal clam fishery on ten beaches in southern British Columbia are presented. Time of day appeared to be more important in determining when people dug clams than state of the tide. Most of the catch (82%), was steamer clams, littleneck, Protothaca staminea, and manila, Tapes philoppinarum, which are also important species in the commercial fishery. Some recreational diggers were targeting on these species but much of the catch appeared to result from random digging. There was a tendency for people to dig larger-sized littleneck clams than manila clams. Interviews showed that 72% of the people had catches within the legal recreational limit of 75 clams in total per person per day. One attempt was made to count recreational clam harvesters over an extended area from an aircraft and methods are described to improve this assessment technique"--Abstract, page vii.
