Abstract
A directed fishery on horse clams is being developed in British Columbia,
Canada. The paper describes how the development follows the guidelines of a
framework, which explicitly endorses the precautionary approach. At the first
phase of the development, biological and fisheries information on horse clams,
such as longevity, reproductive characteristics, growth, mortality, and
management schemes, was synthesised based on scientific literature, technical
reports, and surveys. Growth parameters and natural mortality rates were
estimated in the literature with certain degrees of uncertainties. At the second
phase of the development, alternative management strategies were evaluated and
a precautionary approach for setting up biological reference points was provided
through a simulation study. A stochastic spawning
