Does anyone know about how sustainable squid fishing is, whether it be commercial or for leisure?
I have some views but look forward to what the members think....
Obviously we have no bycatch or impact on the seafloor, apart from lost jigs.
Hint..think about their biology/ecology.

hi blue, as far as i know, the squid fisheries are generally sustainable because squid have a short lifespan and breed like rabbits :th

Yes, I recall hearing that of all the fisheries worldwide, commercial and recreational, squid fisheries are the most ecologically sustainable, mostly due to high reproductive rates, short lifespan, and also the fact that the biomass of squid is INCREASING to 'fill the gap' in the food chain created by overfishing of larger predators like sharks, tuna, etc.

An interesting fact I read recently, the oldest southern calamari squid ever recorded was only 291 days old! :th

Thought provoking stuff !
i agree that of all the fisheries it seems the 'cleanest',but wonder if oceanic species may be overfished in the future.

Hi
what makes you think oceanic waters are going to be overfished?

Re my original question, squid are very short lived and highly fecund...in other words able to sustain high levels of fishing. Habitat and environmental conditions might also be important but i need to research this more. Perhaps someone out there knows about this, Glen?

The funny thing is that the fishery may be based on only 1-2 year year classes at any given time. This means you only need one bad year of spawning/recruitment for the stocks to go down...

Well i guess access to suitable spawning grounds would be pretty important. Then again, I have never heard of any species of squid getting wiped out from poor spawning or overfishing etc. Other factors to consider include the size of suitable habitat, migration patterns, diet, impacts on preferred food (e.g. overfishing)...etc...

Seems to be a large commercial squid industry around Portland.
You still find acres of squid at times when trolling for fin.
Perhaps a good place to search for info. Not sure what research has been done that way, but worth a google.

That's what you mostly see offshore.
I think the pro's do have calamari grounds.
Saw a couple buckets of baby cala's at the marina before.
Good LB calamari first light of the mooring pier opposite the cleaning tables.

The oceanic arrows are more easily caught,and located using modern electronics,therefore they are more at risk of being targeted during spawning aggregations
