A small invasive fish known as the topmouth gudgeon has already wreaked havoc on European species and its arrival to the US and South America is only a matter of time.
This common lionfish (Pterois volitans) was sighted more than 200km further south than expected down the NSW coast by 14-year-old scuba diver Georgia Poyner. It’s one of almost 40 verified observations she has submitted to Redmap.

We know the warming seas are forcing some marine life to new waters, but we don’t know much about how fast and how far they are moving. But now you can help scientists find the answers with Redmap.
Samal, Philippines: protected area to manage fish recovery.

The combination of local fishing rights with adjacent marine reserves creates incentives to avoid overfishing and could improve nearshore, small-scale fisheries around the world.

How will climate change affect life in the oceans? New research shows that the answer is likely good and bad.
The Great Southern Reef is unique, beautiful and contributes significantly to Australia’s culture and economy. However, few of us realise the magnitude and value of this gem right at our doorstep.

We used to think of sharks as primitive fish because the had cartilage instead of bones. Turns out there was a good reason why and it makes them anything but primitive.
Warmer temperatures can throw off the gender balance in some species. But some fish can adjust their offspring’s gender to compensate, but only if temperatures don’t rise too high.
“That’s obscene,” I thought when I saw the photo of Helena Bonham Carter, nude, clasping a tuna between her legs and gazing lovingly into its face. She declared the fish was her “Valentine”. My Western…
Looks healthy, but still lacks the big predatory fish… how would it rate on the index?

We know that fishing has significant impacts on our oceans and the animals that live in them. Effects can range from habitat modification caused by bottom trawls, stock declines from overfishing or subtler…
The feeding habits of an unusual 200-million-year-old fish have been tested in a ground-breaking study published in Palaeontology. This research is particularly notable as it wasn’t carried out by a leading…
Coral reefs are like an underwater metropolis – and function in similar ways.

Consensus is growing that we are steering towards a sixth mass extinction event. There are calls for increased efforts to stop the accelerating loss of plants and animals. But do we really need to protect…
