pulling up a 20kg Cobia

Yeah it was a surprise bycatch as I was chasing flathead off the banana banks 

No worries. They're a pretty cool looking fish.

Cheers for info @ellicat in that case I’m glad I let him swim away 🍻

No size limit. They are supposed to be terrible on the chew. I don't know for sure but I'm pretty sure their spines are not poisonous.

I caught and released one of those Yellowfin tripod fish today behind Coochie Island. 
Do you have any info on them? Like:
What is size limit?
Are they good eating?
are any of their spines poisonous?
cheers mate.
Mick.🍻
