Yes, it is very mature. The article was written in 2017.
They're incredibly hardy, and unlike most other food fish you can easily grow them in simple container setups.
A female Atlantic mackerel typically lays between 200,000 and 450,000 eggs during a spawning season. However, larger, healthier individuals can sometimes produce up to a million eggs, often in multiple batches over several weeks.
it is the mackerel themselves who consider baby mackerel lives to be industrial in scale. they produce that many in anticipation of consumption. Each foodfish humans consume has already slaughtered untold thousands of other fish to grow themselves to size.
'cause they don't have any feelings" - Something in the way
If other fish skins were tried it must have been similar results.
The rules are:
Illegal to Keep: You cannot keep tilapia (dead or alive), sell them, give them away, or use them as bait.
Immediate Euthanasia: Humanely kill the fish as soon as you catch it.
Disposal:
Bury: Bury them deep and well away from the water's edge to prevent scavengers from dragging them back in or floodwaters from releasing eggs.
Bin: Place them in a rubbish bin.
No Filleting: You cannot take fillets and dispose of the rest; the entire fish must be destroyed.
Various state departments have hotlines for reporting tilapia.
There are different hotlines per state:
Queensland Department of Agriculture and Fisheries (DAF) (13 25 23)
New South Wales Department of Primary Industries (DPI) (1800 675 888)
Victoria (VFA) Reporting hotline (13FISH or 13 34 74)
Western Australia Dept. of Primary Industries & Regional Development (1800 815 507)
I've had rewards for reporting them (fishing reel, free bait, etc).
I'm not surprised, a lot of vets I know from Iraq and Afghanistan had used Tilapias for battlefield dressing. Worst case there was a Tilapia MRE people kept around for this purpose. Honestly it's great to see them taking those skills from war and translating them into helping street animals such as cats.
