[Nhcoll-l] Advice on partial fish voucher options

[Katrina Derieg]

Hi Folks,
I’m not a fish person, but I just want to throw my two cents in regarding genetic barcoding. I would caution against IDing a specimen based on a mitochondrial locus, since the mitochondrial and nuclear genomes may have different and conflicting evolutionary histories. But if you have tissues, you can always go back with new genomic tech/knowledge, which is great!

Hi Angela

Yes, I would say a good photo voucher would do the trick to act as a proxy for a physical voucher.  With the advent of CO1 sequencing, the need for a physical voucher has been somewhat reduced – especially for common, easy to identify species.  We have a number of tissues in our collection that only have photo vouchers, or in some cases, no voucher at all.  Not ideal but better than not having the tissue at all in my view.

Hi everyone,

I'm hoping someone has a few minutes to help a mammalogist learn how to deal with fish!

In short, a grad student here is collecting up to 1500 fish this summer for a project on environmental toxins.  Because the fish will be pulled apart to analyze separate tissues and search for parasites, they'll be in poor condition by the time they're in our (the museum's) hands.

My question is whether there is a preferred partial voucher option for fish.  Dermestid-cleaned skeletons?  Dried scales?  Fins in EtOH?  Since vouchering wasn't in the original research plan, we don't have the capacity to formalin fix the remaining carcasses even if that's the preferred option.  We'll be ultracold archiving tissue, regardless.

Thanks in advance,

Angela Hornsby
