ChangJiangjun: The invasion of alien species in rivers and lakes will undoubtedly affect the indigenous ecosystem, but interestingly, some alien species with less ecological damage but delicious flesh will often be "clapped" by many people as soon as they appear.
For example, recently there are fishing enthusiasts in Guangzhou, Guangdong Province, when fishing in suburban reservoirs, they found that there were many "colored prawns" in the reservoir, suspected of artificial release of alien species, but unexpectedly caused many netizens to "interest"...
Much larger than the native freshwater shrimp – a new type of prawn invasion?
01 Anglers: There are a lot of them, but it's hard to catch
Mr. Zhu, an angler in Guangzhou, said that he found this "colored prawn" when he went fishing in the reservoir on the weekend, and thought it was a "mutant crayfish" at the time, until he caught several more, all of which were colorful.
"Fishing for tilapia bait fished up, the mouth is difficult to catch, to not catch more than a lot, this (prawns) nest is very bad, other fish do not come to eat the hook at all, but at the end of the day also caught more than a dozen, I feel that there are many in the reservoir, but it is difficult to catch up ..."
——Mr. Zhu, an angler from Guangzhou.
The biggest one
According to this fisherman, this colored prawn has not been found in the previous fishing in this reservoir, and he suspects that someone has recently released a lot of this colored prawn here.
The release of fish and shrimp aquariums from reservoirs is still relatively common in Guangdong, but it seems that this colored prawn has not yet been released.
What species of shrimp are these?
02 Netizens: 70 a pound, good things
Fishing in the reservoir has caught some unknown "prawns", and this Guangzhou fishing friend also posted this scene on social media.
Unexpectedly, it immediately aroused the attention and hot discussion of a large number of netizens - it turned out that some netizens recognized that this colored crayfish was actually a very delicious and valuable "excellent shrimp", and even some people envied that "this shrimp is 70 pounds, good things, where is this reservoir, I also want to fish." ”
Some netizens commented
Changjiang Jun: This colored crayfish is commonly known as Australian blue lobster, Australian crayfish, red crawfish, etc., in fact, it refers to a creature - the scientific name is four-ridge light shell Nanao shrimp.
The name of this "crayfish" is very strange, and it may be relatively unfamiliar to many people, because this "colored crayfish" is still in the ascending stage in the aquaculture industry, and the current scale of farming is not too large (in short supply).

However, this colored crayfish compared with ordinary crayfish (scientific name Keshi proto-crayfish), the meat is more crisp and tender (the meat yield is also higher), the economic value is far beyond, in the southeast region is indeed 50-70 yuan a catty, belongs to high-end shrimp aquatic products ...
(Yangtze River Jun's note: This Australian blue lobster can be understood as an "upgraded version of the crayfish")

If the "colorful crayfish" that appeared in this Guangzhou reservoir were really released by someone, it was really a "big hand of local tycoons".
After all, from the description of this Guangzhou angler, the number of this colorful crayfish in the reservoir seems to be quite large...
Angler: The biggest three were left, and the small ones were all eaten
In any case, the Australian blue lobster is an invasive alien species, and it is not known how big the impact is on the ecosystem of this reservoir.
03 Angler: Much tastier than crayfish
However, as netizens said, "This is the best shrimp" - according to this fishing friend, the dozen or so "colored crayfish" he caught back are much more delicious than ordinary crayfish!
"Several friends have come (eat shrimp), a dozen are not enough to eat, delicious is indeed delicious, more delicious than crayfish, is too expensive wine, hahaha already know not to fish."
——Mr. Zhu, an angler in Guangzhou.
Cooked much like a crayfish, but more delicious and crispy
Old drivers, do you have this "colorful crayfish" in your local area? What do you think of the invasion of this new alien species?
