This goes along with some recent statements (some direct quotes) I heard from DMF folks in the last year:
How about we buy back fishing licenses to see if people sell them to us?
How about we tag fish that we keep and not the ones we release?
SB populations are not down from years past, it was just we had too many back then. (seriously)
Those draggers were not probably not fishing in muskegut channel they were probably just cleaning their nets.
We monitor bunker in MA...the populations are down.
It is OK if the bulk of the quota comes from one spot...we have a quota so we don't over fish.
"we have observers, no comm fisherman is taking herring"
"Codfish have been overfished for the last 150 years"
" I sleep good at night"
I have given up on all hope for any kind of future fishery.

Simple logic. If (lets just say) one in ten thousand elvers survives to become an adult silver eel, then a fisherman could catch nine thousand elvers and not do as much damage as a bait fisherman catching one adult eel. The real problem with eels is the water turbines that kill thousands of adult (silver) eels when they migrate downstream to spawn.

Those 9000 elvers aren't just dying of natural causes, most are probably being eaten by natural predators. Remove the 9000 and the natural predators just eat the 1000 that are left.

I disagree. most predators are opportunistic and if the eels are there they'll eat something else. Also we don't know what the causes of natural mortality are, so it is merely an assumption that it all due to predators. As I said before, the main cause of mortality on adult, silver eels is hydroelectric dams.

It's a systems problem though...unless steps can be taken to reduce human caused mortality you still only have the remainder in the food chain. If predators shift to other food sources does that pressure other threatened species?

If what you are saying is that its all interrelated and what we really need is ecosystem management, I couldn't agree more. The problem though is that relatively little is known about the ecosystem, so there is little to base any ecosystem management on. One easy fix is to shut down hydroelectric turbines during the prime migration of silver eels to the sea, but NOAA/NMFS doesn't have the authority to do that, so the killing continues.
