Implications on assessment of the British Columbia prawn populations with the adoption of a quota management system / J.A. Boutillier and J.A. Bond.: Fs70-1/1999-130E-PDF

During the last three years fishing intensity in the prawn trap fishery has risen dramatically, with the 1998 fishery lasting only 93 days coastwide. It has been suggested that a less intense fishing pattern over a longer period would be favourable, and fisheries managers have been considering the possibility of adopting a quota type system for prawns and abandoning the current fixed escapement framework. This paper discusses the critical problems and questions that must be answered in order to develop a quota management system, such as determining the population size, the spatial scale of the population, and how the population responds to exploitation, and considers methods of addressing these problems. It is noted, however, that many such methods may prove difficult to implement for prawns and that the data and analytical requirements would be substantial, making assessments of the prawn stocks highly expensive.
