"Not to be cited without permission of author." Includes bibliographical references (page 7). "Growth data for one Newfoundland area were run on the Ennis and Akenhead lobster yield per recruit model at different natural mortality rates. Even at the highest level of natural mortality considered, the model predicts increases in yield per recruit for increases in recruitment length above the present 81 mm carapace length and for decreases in exploitation rate from current levels (around 80%). Yield per recruit curves from this model and those from the Beverton and Holt model using the same growth data are compared"--Abstract.
