<div class="yiv6329605892MsoNormal"><span style="font-size:10.0pt;">Hi</span></div>
<div class="yiv6329605892MsoNormal"><span style="font-size:10.0pt;">We, at the Australian Museum in Sydney, are currently in the process of moving a large dry shell collection from one storage facility to another. The dry shells are currently
housed in a number of different ways ranging from open shelving and plastic tote bins, to approximately 1400 unlidded archival trays, each approximately 0.5 m square containing shells in press-seal plastic bags. Unfortunately, we have had an outbreak of silverfish
in our storage facility and are trying to come up with the best way of treating the specimens prior to rehousing at another facility (the issue, of course, is the possibility of silverfish eating the specimen labels).
</span></div>
<div class="yiv6329605892MsoNormal"><span style="font-size:10.0pt;"> </span></div>
<div class="yiv6329605892MsoNormal"><span style="font-size:10.0pt;">We appear to have two options:</span></div>
<div class="yiv6329605892MsoListParagraph" style=""><span style="font-size:10.0pt;"><span style="">1)<span style="font:7.0pt;">
</span></span></span><span style="font-size:10.0pt;">Gassing in the absence of oxygen (a nitrogen ‘fumigation’ chamber). This will take many weeks, involve opening thousands of press-seal bags and sealing them again
after treatment.</span></div>
<div class="yiv6329605892MsoListParagraph" style=""><span style="font-size:10.0pt;"><span style="">2)<span style="font:7.0pt;">
</span></span></span><span style="font-size:10.0pt;">Freezing (at approximately -20 degrees c): Simpler, quicker, less handling involved, cheaper option.</span></div>
<div class="yiv6329605892MsoNormal"><span style="font-size:10.0pt;"> </span></div>
<div class="yiv6329605892MsoNormal"><span style="font-size:10.0pt;">We would be grateful if anyone could share their experience of freezing mollusc shells. (I have heard that delamination of some shells e.g. cowries, may be a problem and fragile
shells may break. Is this a huge risk? The shells range in size from micromolluscs to giant clams)</span></div>
