[Nhcoll-l] bagging and thawing or thawing and bagging?

[Dirk Neumann]

Hi all,

a brief question regarding bagging of dry shark fins that were 
confiscated by customs (approx. 50 kg) and deposited in our collection. 
When the material arrived, boxes were full of life with thick layers of 
beetle remains at their bottom. We kept the fins mostly frozen so far 
(several freezing / thawing cycles to kill the critters) but now have to 
move the fins into our storage area where they will be kept at room 
temperature.

Because of major renovation works, our climate control systems are 
currently shut down thus temperature and rH are fluctuating and not 
really stable, thus I was wondering if I should seal small subsets (5-10 
fins, depending on their size and volume) while they are still frozen to 
avoid that tissues would attract too much humidity during thawing. Of 
course this would cause condensation inside bags after sealing to some 
extent, but given the small total volume of air inside the bags, 
potential negative effects might be negligible ? Bagged fins will 
finally be stored in transparent plastic boxes to allow easy monitoring.

Any ideas/ suggestions would be welcome; thanks in advance

Dirk
