New Invasive Fish

This doesn't sound good.

Well that sucks  .

Whose great idea is it to raise potentially invasive species in foreign oceans?

 

Ohhh...but cobia are awesome to catch on hook and line and spear and taste great!

 

JK...kinda....

The article fails to mention whether the fish are triploids (or otherwise sterilized). I think Ecuador gets it's cobia broodstock from an American aquaculture facility in Florida...I hope they sterilize their fish. 

Dr Love said they have a 50-50 chance of spawning...so I assume they aren't triploids.

Maybe someone could explain to me why the chances are only 50/50 if they aren't triploid. 

Whenever I see 50/50 printed anywhere I'm a little skeptical because there is a long running internet meme that the chances of anything are 50/50 - Either it will happen or it won't - no matter how unlikely.  So the chances of a massive asteroid strike on earth in the next 5 minutes are 50/50.  Etc.

    Better Cobia than something like the lionfish.

One possible answer is they may require a certain population density to gather and spawn. Solitary fish that do so must have some mechanism for finding each other for breeding. Below certain numbers and in waters for which they are not evolved, they may not be able to reproduce. Crossing fingers!

Heck Yeah!

 

Let them breed!

That may have something to do with Dr Love's mild skepticism/optimism. Or he's just not sure if the right ocean conditions are available for them to spawn.

Let them breed!   

And then put a bounty on their heads and let us slaughter them.

Remember Jurassic park?  "Nature always finds a way to reproduce"

Bring on the Cobia.  Fished them when I liven in Florida and are awesome fish to catch & eat.
