When writing the article on the Yangtze Finless Porpoise, I briefly touched on the topic of overfishing. Many of you have probably heard about it, and know it is a massive problem threatening our seas and their inhabitants. Overfishing is so destructive, it can kill all life in the ocean, and many of you might be part of it every day. So I read through many articles from international organisations, and they all say pretty much the same things. It's a highly complex topic, with so many things to say and do, so this is just an introduction to the broadest points. It's very interesting (and sad) but when you look into it further you realize there is actually a lot you can do! This is very important, especially for ocean lovers and seafood people.
What is overfishing?
By definition, overfishing is so intense fishing, people catch fish quicker than the stocks can reproduce. Leading to a massive decrease in stocks that can peak in the extinction of a species. Overfishing is closely related to bycatch and Illegal, unreported and unregulated fishing (IUU). The thing is, when an entire species of fish are wiped out, an ecosystem can collapse and that in return can collapse fisheries. However, billions of people rely on fish as their main source of protein, and if the seas can not provide our demand for fish and collapse, we'd face a food crisis. That is not the case just now though, as it looks like people catch way more than the demand for fish there actually is. That simply is an unnecessary waste of billions of fish lives.
Bycatch
Bycatch is the unwanted animals caught along with the fish that was initially targeted. Often bycatch is sea turtles, other fish species or seals that are caught along in the gigantic nets. Due to the sheer masses of bycatch, many of these species are now endangered. But for the big companies, that is no reason to stop. All they care about is having enough fish for the demand. Only that many provide way too much and so many lives are ended for nothing. Bycatch is a huge threat to marine species, especially as huge quantities are always caught and lots of animals die. If you do not consider how many fishing boats go out to sea every day, the amount of deaths is extremely sad!
