Looks like it's the same everywhere you go. Back in Korea I used to complain because there, they allow netting; there were gill nets strung out every few feet which made boating hazardous with the nets and the ropes strung everywhere. And at least half the nets were unattended, rotting away and sinking under the surface so that they would catch your prop or lures.

The nets were set out to catch anything that swam (but mainly carp), and the sad part was that a lot of the time, the netters wouldn't come and check their nets which led to so many fish dying. And the ones that did check their nets on a daily basis, they would keep anything they caught, regardless of size. Made me wonder how the bass ever survived.
