I stared diving in 1990, my last dive was in 2005 when my wife was 7 month pregnant with our last son. There have been Mickey Mouse dives since but nothing serious.
I can tell you that just over the 15 years or so the reef around Cozumel change tremendously. I don’t think that change does not have anything to do with fish collection, but due to human activity as a whole.
Don’t ask me for scientific evidence because I don’t have any. I don’t dive a huge amount. Just my experiences Ofer checking the same spot over 15 years.
over the last 15 years my family and professional life just got too hectic, and the children were too young to have diving vacations. They get first choice of destinations.
