Evolutionary regime shifts in age and size at maturation of exploited fish stocks

Selection differential S is calculated using standard techniques Taylor , equating individual fitness with the number of eggs spawned. Dashed lines in right panel project consequences of continuing harvesting at the same intensity and size threshold. Results a Evolutionary dynamics in equilibrium populations For a wide range of parameter sets that we examined, the unharvested population exhibits year-to-year fixed-point dynamics, in which population abundance and size distribution is the same after each spawning event. Given that the contribution to lifetime reproductive output rapidly diminishes with age due to mortality, we argue that this different energy allocation model would only lead to small quantitative differences. However I don't descriminate in my taste in women - young or old if they have a pussy, I'd fuck it! Our results show that successful management of such complex, adaptive systems is not straightforward and requires a careful unravelling of all the feedbacks in the system that influence individual life history on ecological as well as evolutionary timescales.

Life-history evolution in harvested populations: Also, in the model exhibiting fixed-point dynamics, we assumed a positive correlation between growth rate and maturation size, which benefits individuals maturing at larger sizes. Only a swift and complete fishing moratorium imposed less than 40 years after the onset of harvesting can reverse the trend solid arrow in figure 4. The number of recruits relates to the number of eggs spawned the previous year. It is a generic representation of the interaction between a size-structured fish population and its shared resource base, although it is parameterized for a particular, well-studied species.
