Chinese fishermen are illegally trawling South American waters, inflaming tensions with the US. But for centuries Washington used aggressive fishing to expand its overseas presence, too.

Hurricane Harvey destroyed the fishing infrastructure of Aransas Bay and reduced fishing by 80% over the following year. This removed humans from the trophic cascade and whole food webs changed.
An enormous amount of fishing gear is cut loose in the ocean each year. The losses cut into fishers’ profits and kill marine wildlife. A new project aims to get ghost gear out of the ocean.
Everyone who cares about marine biodiversity, fish, fishers, coastal communities and fishing industry workers of today and tomorrow must push for the end of fisheries subsidies.
In the 1800s, Americans hunted many wild species near or into extinction. Then in the early 1900s, the US shifted from uncontrolled consumption of wildlife to conservation. Could Asia follow suit?
Fish must be released into good quality water, with suitable habitat and lots of food. These conditions have been quite rare in Murray Darling rivers in recent years.
Biodiversity is often highest in places with human activity. The fishing industry has shown we can often have it both ways: maintain important livelihoods while protecting precious marine life.
Fishers who hunt wild tuna use fish’s natural attraction to floating objects to lure them to known positions near GPS-equipped rafts. However, these rafts are attracting increasing concern.
Fish can’t read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.

As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.
