- W2055770897 abstract "Lobster fishery scientists measure rates of growth, mortality, egg production, and catch per unit effort and use these measurements to derive other rates used for management targets. I propose that targets be based instead on annual landings. These would not be quotas to limit catch, but optimistic objectives to reach for, positive goals easily understood by stakeholders. Recent high landings in Canada have challenged our assumptions on potential stock production; four areas are 3–5 times their long term average. Increasing already high fishing mortality will not improve yields. Rather, levers of stock regulation would be chosen by stakeholders and adjusted on a trial and error basis until yield targets are achieved. Egg production, yield per recruit (Y/R), preserving habitat, and preventing waste during fishing are candidate levers. Much effort has been expended trying to answer the very difficult question of how many lobster eggs are enough. How many eggs are more than enough is a larger target and is as affordable because eggs are inexpensive. Monitoring abundance of ovigerous females, larvae, early benthic stages, or juveniles would provide early feedback on the success of lever adjustments. Areas reserved for experimental fishing would also be useful for testing stock response to lever adjustments." @default.
