This goes back a few years. My research was fundamental and aimed at understanding the link between larval growth and survival. We now know that the strong cohorts really emerge at the larval stage. These are the factors that favour or disadvantage larval survival and really affect the stocks that can be fished four to five years later.
Right now, the conditions for recruitment in the southern gulf are not there for mackerel, but the system is very variable. We can hope that the stock will be able to come back, but we have to take care of it.
