Groupers are mostly protogynous, meaning that when they become sexually mature, they are always females. Only later in life, when they have grown bigger (and have the right environmental influences), do they transition to males. This species can live for more than 30 years, but that’s actually relatively short for a lot of the grouper species, some of which can live to 60 years or more. Scamp grouper come together in groups to reproduce, so this makes them vulnerable to overfishing. The management councils take this into consideration when making a management plan and will close off areas known to be spawning grounds during the reproductive season.Read the blog post
