Consideration of snow crab yield per recruit incorporating terminal molt and a differential harvesting strategy / by R.K. Mohn and R.W. Elner. : Fs70-8/88-14E-PDF
"A yield per recruit model is presented as an adjunct to the assessment for Atlantic coast Cape Breton snow crab. The assessment posed a harvesting strategy which preferentially exploited males in terminal molt status. A potential method for such preferential exploitation is a ring which sets a minimal chelal diameter limit as opposed to the current limitation based on minimum carapace width (CW). As is standard for yield per recruit analysis, the model incorporates growth and mortality rates. However, growth in snow crab must include the probability of entering terminal molt over a wide size range. The model presented allows for fishing mortalities to be applied independently to terminal and non-terminal animals"--Abstract, page 2.
