Pest fish busting is catching on in Australia

I thought I didn’t have anything to write about so I went to our national news site to try to find something that might be interesting. And I had quite a field day!
Firstly, have you heard of pest fish-busting? This is the sport of fishing for invasive fish species that are threatening native species. The sport is fast catching on among fisherpeople (Note the non-gender specific term!) and pest fishing contests are pulling in large numbers of contestants. Carp and Mozambique tilapia are two of the species targeted.
Mozambique tilapia was introduced to Australia about 50 years ago as an ornamental aquarium fish and are considered a huge threat to the aquatic ecosystem. It is now illegal to keep them in Australia or to use them as bait.
As they can survive salty and oxygen-starved waters, they are found in lakes, reservoirs, drain, swamps and creeks. So far, they are mostly found along the eastern seaboard and north of Geraldton in Western Australia.
Although tilapia is a primary protein source in some countries, and I’ve heard ‘tilapia’ mentioned in myLot discussions, it is not permitted to take them as food fish here. This is because females carry their eggs in their mouths until well after they hatch. The eggs and babies can survive long after the death of the mother.
The anglers share pictures and videos of their catches, and maps of where to go to combine a love of fishing with helping protect native species.
I don’t have a photo of a fish but the one here is the tail of a whale.

A good method for reducing the number of invading species. That, in my opinion, is one approach to remove them from the environment while allowing the local species to recover their growth.
A similar thing happened in one of our lakes which was formerly thought to be home to the world's tiniest fish, but people later learned that the tilapia industry was prospering at the time and introduced it to the lake. As a result of eating all the local fish there, the tilapia harvested there were larger than usual. Currently, it appears that the smallest fist is almost extinct.

There are people advocating using invasive species as food. In Louisiana there is an orange-toothed thing called Nutria, and I saw Andrew Zimmern on Bizarre Foods eating it. The invasive species rarely have predatory enemies, which makes things worse.
Good luck to your fishermen in helping getting the problem under control!!!

I had tilapia once, at a good seafood restaurant chain. To me it tasted like mud. I wondered if it was farmed. It sounds like people have found a fun way to deal with a problem.

At some places they pull in two or three hundred in an afternoon. Surely it has to be helping reduce numbers.

@allknowing It's either that or have our native species go extinct.

What a great idea that is. I'm not sure if that is done much in the US, but it should be. I know that Florida pays a premium for people who have proof of killing pythons in the Everglades.

The python is another example of an introduced species that has no predators in its new environment. I've heard it is a big problem there.

@Ronrybs Muntjac rings more bells for me so I think maybe it's the muntjac, although there are sika deer in the UK too. The muntjac escaped from Woburn Abbey around 1925 and I understand it is quite a pest there now and has spread widely.

There are also companies in Florida that are killing iguanas by the hundreds. They are just one of the invasive species in that state. I'm glad to hear that they are trying to get rid of invasive fish too.

We don't eat a lot of fish although I know they're good for you.

I eat varieties of fish, but never tried tilapia.
