Loan Conditions



The collection maintained by the Ichthyology Section is property of the scientific community. Our duty is mainly to keep the collection in good condition for eternal use, and to make it available for scientific study. Thus, we permit loans to all scientists worldwide that are doing systematic revisions or comparable work.

The following restrictions apply:

  1. The loanee must be permanent staff of a research museum. If you are a student at a museum, we will lend to your supervisor or the curator of that museum. If you are based somewhere else, please make an agreement with the nearest museum to study the material there.
  2. The lending institution must practice a reciprocal loan policy, i.e., permit loans to active researchers for the time it takes to complete a study (often several years).
  3. Alcohol specimens must be maintained in pure 70-75% ethanol. Ethanol denaturated with methanol or some other destructive substance must under no circumstances be used.
  4. Loans are made for periods of 3, 6 or 12 months. To keep it longer, just write, or reply to our reminders. Failure to reply to the second reminder will result in some action from us.
  5. Any kind of dissection or treatment that damages specimens requires prior authorization from us.
  6. We may refuse a loan if we feel that the loan is not necessary for the study for which requested.
  7. Linnaean types are not lent, because they are sort of cultural heritage. All other type specimens are avilable for study by loan.
  8. All international loans must be shipped by air mail. Packages containing types must be fully insured, other packages must be insured for the same amount as we have insured them for. This means that unconventional means of transport must be sought for countries not having a system of mail insurance.
  9. Loanees are not allowed to maintain specimens in any location other than the permanent institutional address of the loanee. This means also that loans cannot be transferred without special permission.
  10. Loaned material listed in a description of a new species must be designated as paratypes of that species, unless holotype.
  11. If tissue is lent for biochemical research (usually DNA sequencing), all tissue remaining after sampling, all sequences obtained, and all extracted DNA not consumed during analysis, has to be returned.
  12. Any changes to these conditions applies retroactively.
