We hear all about land species disappearing ... but not much about those species in "the deep". However whenever I read about it it seems there is a serious problem down there ...
Our planet is mostly water .... it needs to be well managed ... are the oceans being overfished?
Many of the larger shark populations have declined in excess of 90% in the last 20 years.
Cod stocks began to collapse in the northern hemisphere in the 1960's (ish).
The methods we use to fish are also problematic, which destroy the ecosystems over time that the larval / adult fish depend on.
Ghost fishing kills many species of fish, birds, mammals.
Pollution / rubbish etc also major problems.
Larval fish are also being harvested to supplement aquaculture.
Tuna are herded into pens (I believe they do this for other species too).
Tools hunt trophy fish for fun, this often kills them.
Shark finning kills ~200 million shraks per year.
Not only are many fish stocks declining in number, but they are also becoming smaller in body mass (due to lack of time to grow to full maturity).
Overall I think the oceans have been mis-managed for decades, i hope we can resolve this situation and quickly.
