<p class="MsoNormal"><span style="color:#1F497D">The DNA work was done at another university, one that does not have collections to maintain vouchers. The DNA was collected and analyzed from these vouchers, the paper written and submitted for publication, and
 the author/researcher wants to deposit the individual fish as vouchers. Shoal Chub (<i>Macrhybopsis hyostoma</i>) are small, the largest maybe 5 cm long. My institution does not have any of the removed tissues that were analyzed for DNA, nor any products from
 that DNA, only the fish themselves. The researcher’s preference is for individual containers for each specimen should someone want to extract new tissue for DNA. Doing so would mean an approximately 10X increase in shelf space and material necessary to maintain
 these vouchers. Since we do not have the DNA samples or products, and are holding only the fish themselves, I submit that we should individually package each fish with its information but maintain all the samples from the same collecting locality in joint
 jars (4 jars instead of 35). Yes, cross-contamination would potentially occur between those jointly held samples, but since they are from the same collecting site cross-contamination would also be true in the natural environment where they were collected.
 Being small one option is to stuff them into individual tubes and put them in the freezers with tissues from other specimens where the vouchers are at this institution. That might work in this case but doesn’t lend itself  to ready access for species verification,
 nor does it function well as policy or protocol should another project produce larger numbers of samples from larger species.

 or do you mean fish from which DNA will be extracted in the future? <o:p></o:p></span></p>

 example, see von Endt 1994, "Spirit collections: a preliminary analysis of some organic materials found in the storage fluid of mammals," Collection Forum 10(1):10-19). Whether that contamination would affect the DNA in the fish specimen itself has not been
