There has been several questions about when Frank Lallo did his survey and some discussion of mortality numbers. Just thought I'd quote some of the source material...
Peter Rubec, et al "Cyanide-free net-caught fish for he marine aquarium trade",
Aquarium Sciences and Conservation 3: 37-51, 2001:
While trans-shipped fish are cheaper, many fish are dead on arrival (DOA) or extremely 'stressed' when they are received by retailers. To the trade, stressed means the fish arrive in poor condition, and many die shortly thereafter. Several retailers on the U.S. East Coast have reported higher mortality with fish purchased from trans-shippers (>60%) in comparison to fish obtained from traditional importers (30-40%) situated in Los Angeles. In addition to all of the above, there are reports of fish being left out on the tarmac by the airlines in mid-winter that are 100% DOA.
An IMA telephone survey, conducted by one of the present authors (Frank Lallo) during 1997, of over 300 U.S. aquarium retailers determined that mortality of marine fish (DOA and during the following three days) was on average: 60% on the east coast, 35% in the mid-west, and 30% on the west coast of the U.S.A.
Peter, if it is not okay to quote your paper directly like this please contact me and I'll take it down. I just thought that it would be good to get some of the source material in front of the readers eyes.

interesting
the first impression i get is that this points right in the direction of airline/transit time, handling being THE major mortality issue, stateside
(look at the change from east coast to west.the specific mention of the shipments on the tarmac even predisposes the passage to that point)
the question(s) i'm most interested in is, however, what decision making process the individual(s) went through to arrive at
a)how a telephone survey, even if answered truthfully by all participants, is even mildy valid statistically/scientifically, or representative of most of the industry, or able to stand the test of peer revue, if used to back up any statements/claims as data,
and..
b)how did the surveyor(s) assure themselves of the participants veracity ? did they do any independent, 3rd party, checking on the answers given ? (like store logs? invoices, r.o.i. for the livestock sw dept of the lfs, etc?) airway bills ? did they just ask an lfs if they sold sw stock, and go on from there?
i've had customers try to return fish FROM OTHER LFS'S to ours, to try and take advantage of the 7 day warranty the store had-if we didn't have a log of the fish, date, and salesperson, w/their signature, we wouldn't have tripped up nearly 100% of the false claims (one also should know what freezer burn looks like :wink: ))
it's certainly possible that even an honest responder could be duped by his own patrons into thinking his DAA is higher than it is 8O
if the method mentioned above is the main base for the argument of the '30% at each step' or thereabouts claim that is being used to focus on cyanide, and NOT handling, you're on very shaky ground at best
there is absolutely no way to either trace, verify, or back up the assumed data, which was collected with one of the most amateurish methods available to the surveyor(s), and the shift in mortality rates almost flashes a red sign in front of 'airlines and time in transit'
when i was younger and foolish enough to transship, my daa was higher than when i bought from a wholesaler that tanked the fish in cali
that survey just backs up the common sense notion that the longer a continual time a fish spends in a bag in a styro, under transit conditions, the more likely it is to die, and does nothing more
there is no clue to a cyanide issue in that passage, whatsoever, nor any means to assume one
i'm actually shocked
