<p class="MsoNormal">What kind of stopper do you use in vials that are submerged in fluid? Presumably they must be impermeable, to prevent cross-contamination, but does e. g. polypropylene last well under full immersion? I know that phenolic does not – it will
leach into alcohol after only a few years. <o:p></o:p></p>

<p class="MsoNormal"><span style="color:#1F497D">We have used vials within jars to keep tissue vouchers separate and prevent cross-contamination. You can vary the vials size based on the size of the fish and as such it shouldn’t take up too much more space
– even though it will take up a lot more of your time </span><span style="font-family:Wingdings;color:#1F497D">J</span><span style="color:#1F497D">. Having said that I wonder how much cross-contamination you would get after the fish have been preserved?
Not sure that there would be much floating around in the liquid after preservation that wouldn’t be drowned out by sending a tissue sample from the original fish for analysis.</span><o:p></o:p></p>

<p class="MsoNormal">Greetings from snowy central North America!<o:p></o:p></p>
<p class="MsoNormal">Has anyone developed policy or protocol for the receipt, treatment, and maintenance of eDNA fish voucher specimens? Would you share? The individual fish are small and the researcher recommends keeping each individual in a separate container
(how they were delivered) to prohibit cross contamination of DNA via the ethanol solution. That is understandable but will utilize lots of space and containers.<o:p></o:p></p>
