Restoration/renovation

Rehydration

• Osmosis via rehydration chamber (Singer protocol adapted from John Simmons method for herps). Most economical method with least chance for damage to specimens. Protocol involves using warm DI water, thymol crystals (anti-fungal), sealed glass container and a mesh, pliable and water resistant material (e.g. rubber mesh or chicken wire).

Deaccessioning

Labels and systems for printing

• Pre-printed labels with blanks for required information are best so collectors in the field know what is expected. Can be on ‘rite in the rain’ paper, linen resistal paper, other paper that does not degrade in ethanol, isopropanol, or formalin solutions. Use pencil or indelible ink. No sharpies! See field collecting subcommittee for data fields.
• Archival (long term): thermal impact printer labels (Datamax printers, polyester labeling media, special SDR ribbon for alcohol solutions). Alpha Systems is one vendor.

Identification and sorting of collected material

Keep accession and field numbers with specimens

A summary of sorting fish eggs and larvae is found in Smith and Richardson (1977).

Accessioning

Required paperwork: permits, international declarations (e.g. USFWS form 3-177) if appropriate, copies of field notes, collections notes; documentation demonstrating legal acquisition and ownership of specimens (Deed of Gift form), any copyright transfers that may relate to photographs, etc.

Cataloging

Matching subsamples with whole specimen in lots with >1 individual: Give sub-sampled individuals a unique catalog number (lot is now n=1) and cross-reference old catalog number and new catalog number. Alternatively, tag individual with its own identifier, such as catalog number XXXXX 1 of 6. Tag tissue and individuals with same identifier and ensure that tags stay with individuals: place or tie tag in gills, mouth, body cavity, or wrap individually in cheese cloth.

Georeferencing (see Digitization)

Collection organization

• Taxonomic: By family, then alphabetical by genus and species

Recommendation: Most recent edition of Eschmeyer or Nelson

Examples of institutional organisation by taxonomic authority:

• Alphabetical: By genus and species
• Geographic
• Temporal (e.g., by cruise)
• Catalog number

Storage in collection (containers)

Sensitive and rare specimen handling/preserving

• Types:
  • Mark jars (with ribbon around neck or write on lids).
  • Store separately (under lock and key).
• Other special specimens: Use ribbons, wires, etc. around jars to indicate.

Clear glass, screw-top jars

Type of glass: Borosilicate (preferred, but expensive). Flint glass is readily available and a very good option. The ideal lid for these jars is polypropylene with an F217 tri-seal foam liner, a knurled (ribbed) edge, and a buff (rough) top.

Potential vendors:

• Kols/Oberk,
• Duval
• William R. Hill, Co. (http://www.wmrhill.com)
• General Bottle (http://www.bottlesetc.com)
• Continental Glass
• Wheaton
• Fisher
• VWR

Standard Sizes (check with fire marshal for allowable sizes)

Bold = commonly used by most large fish collections in North America.

Glass Gasket jars

• Le Parfait jars – unique sizes, wide mouth (0.5L, 1.5L, 2L, 3L). Buno white, rubber gasket.
• Bail-top jars - not recommended for new collections. If you are already using them, you need to check gaskets for cracking and replace.

Plastic Containers

(polypropylene lid with F217 tri-seal foam liner (as above for glass) PET (polyethylene terephthalate) HDPE (high density polyethylene) Vendors: University Products: 1-22 quarts

Vials Containing Whole Specimens

Stored within larger, fluid filled jars. All vials are stoppered with cotton or synthetic polyethylene stuffing (no phenolic black plastic). Vials are stored cotton end down in case of evaporation (be sure to pack cotton well, or fish will fall out!). Vial labels are a smaller version of a standard adult label. One small label has catalog number, ID, abbreviated locality (often only a field number to save space) and identifier’s name or initials. A large cover label goes into the large jar with a header that has the species name then a list of the catalog numbers and abbreviated locality.

Stainless steel tanks

Vendors:

• Delta designs
• Stainless Steel Manufacturing
• J.W. Appley
