A new tool called EcoCast helps fishermen in the West Coast figure out where it's best to fish that day.
When a stream enters a culvert, the flow can be concentrated so much that water flows incredibly fast. So fast, in fact, that small and juvenile fish are unable to swim against the flow and are prevented from reaching where they need to go to eat, reproduce or find safety.
Our new invention tackles one of the greatest impediments to fish migration in Australia: culverts, those tunnels or drains often found under roads.
Lake Victoria sees high levels of illegal fishing carried out by local fisherman and traders.
Urgent measures need to be adopted to prevent corruption linked to illegal fishing activity in and around Lake Victoria.

Australia was thought to have some of the most sustainable fisheries in the world, but a recent count has found that fish numbers have plummeted by a third.
Hoki is one of New Zealand’s most valuable export fish.
Leaked reports reveal that some of New Zealand's largest fishing companies have been under-reporting their catch of the commercially valuable hoki by hundreds of tonnes.

Seagrass meadows play a significant role in supporting world fishery productivity.
Sustained ocean warming could greatly reduce catches of fish like these herring photographed off Norway.
Fish are a key food source for millions of people worldwide. But a recent study finds long-term warming over the next 200 years could starve tiny plankton, with impacts that would ripple up food chains.

The recent Arctic Council meeting in Finland shows there's still avid interest in developing the Arctic. Some are arguing the entire region should be considered a 'global commons.'
Farmed fish like these carp now make an important contribution to global food security.
Many critics say that fish farms mainly sell their output to wealthy countries and don't provide much benefit to poor people in producing countries. Three aquaculture experts show why this view is wrong.
