I can take that.
We did a study three years ago on the effect of temperature and potentially fishing on the change in size and maturity. What we think is that when it's warmer, lobsters grow a bit faster. Then they tend to mature at a smaller size and have smaller eggs. This is as a consequence of temperature. It can also be as a consequence of fishing pressure. If you get very high fishing pressure, you tend to remove larger individuals in your population. Then you get only smaller individuals with faster growth rates and smaller size and maturity. Temperature and fishing can lead to smaller size and maturity, which ultimately leads to lower egg production in your population.
