I thought they were a protected species in Oz?

^ A sad thing at the Nong Khai aquarium was seeing how many Mekong basin fish are classed as endangered. I don't reckon there will be much left in 20 years.
^I don't think the damming helps matters also.

Possibly taking steps, similar to Chinese authorities, may help. Introducing their own suitable fish species.
10,000 Chinese sturgeons released into Yangtze River

"On April 22, 2020, a total of 10,000 Chinese sturgeons was released into Yangtze River in Yichang city, Hubei province in central China. This is the 62nd release by The Chinese Sturgeon Research Institute of Three Gorges Corp, also the largest scale in recent years.
In the last seven years, the number of Chinese sturgeons released were: 2,000 (2014), 3,000(2015), 2020(2016), 500(2017), 500(2018), 700(2019) and 10,000(2020). According to statistics from WWF, a total of 5,030,000 Chinese sturgeons has been released in China since 1984.
After releasing, the Chinese Sturgeon Research Institute tracks them through sonar monitor system along the river.
The reason for such a big number of released fish this year is that experts have successfully induced two adult females, both fourteen years old, with the help of technology, increasing the survival rate of young fishes.
All the Chinese sturgeon released this year are artificially bred. They were released in April because the water temperature rose in spring, and there are enough aquatic creatures to feed the fish.
Moreover, fishing is banned on Yangtze River in April, which ensures the safety of released fishes.".
The other Mekong basin countries may do similar when they too become "moderately wealthy countries". To ensure none of their citizens get left out of economic benefits.

A tray full of GOLD is not worth a moment in time.
^^ they will really enjoy struggling through all the pollution, still lets hope Xi and the party enjoy their caviar
Yangtze River Pollution
According to report by the Chinese Academy of Science released in April 2007 the Yangtze is seriously and largely irreversibly polluted. More than 600 kilometers and almost 30 percent of the major tributaries are in critical condition. In 2002, Beijing announced it was going to spend US$5 billion to clean up the river but the river remains as polluted as ever.
The Yangtze River is polluted with 40 million tons of industrial and sewage waste. Half of China's 20,000 petrochemical factories lie on its banks. About 40 percent of all waste water produced in China---about 25 billion tons---flows into the Yangtze, of which only about 20 percent is treated beforehand.
The pollution has taken its toll on aquatic life. Deformities to fish such as one or no eyes and misshapen skeletons and decreasing numbers of rare wild Chinese sturgeon in the Yangtze have been blamed on a paint chemical widely used in Chinese industry. The Chinese sturgeon has been around for 140 million years. It grows very slowly and was among the first class of animals to be protected in China. Harvests of aquatic life from the river declined from 427,000 tons in the 1950s to 100,000 tons in the 1990s. The Yangtze is in danger of becoming a “dead river” unable to sustain marine life or provide drinking water. See Yangtze River Dolphin, under Nature, Animals and Animals and Plants again.
^ good lord you are one boring fker Lom, perhaps getting back on topic you could solve Mendip's fish problem by popping over and talking them to sleep so they float to the surface
I like herons, they are good indicators of healthy fish stocks helge
Kill one round my way and i'll rip your horns off - you can Valhalla all you like
First you force Ant into his bed, and now you want to de-horn me ?
Worried about some footie tonight ?
Sorry to hear about the lad, Calpol him
Yes sorry Mendip, well be in trouble with Lom, Shhhh
Today I finally had some time to start sorting the pond out.
There's been a lot of rain about so my plan is to drain the pond in the next few days and remove the unwanted fish, keep the good fish and restock with pla nin and pla tabtim fingerlings. I was hoping to head down to Chon Buri to pick up a paddle wheel aerator but with the Covid restrictions that plan has gone on hold for the time being.
Today I thought I'd get ahead of the game and start catching the pla sawai that now dominate the pond, and also hopefully catch a few of these bladdy snakehead, or pla chon.
