| Lineage | Biologists walk through areas where pinnipeds have hauled out on San Miguel Island. They collect individual fresh (i.e. minimal dessication) scats into Whirl-Pak or mesh bags. Scats are kept at room temperature until they arrive in the laboratory from the field and then frozen at -20 until processed for contents. Prior to 2002, scats were thawed and soaked in warm water with detergent for 24 hours and then rinsed through nested sieves. Prey hard parts were recovered from each sieve and placed in vials. Prior to 1996, only cephalopod beaks and fish otoliths were retained and identified. After 1996, all fish hard parts and cephalopod beaks were identified. A change in processing methods occurred after 2002. Scats were thawed, placed in a washing machine and washed on the gentle cycle to remove organic material (Orr et al. 2003). Prey hard parts were collected and placed in vials using post-1996 methods. Each vial was labeled with date and scat number. Fish parts were stored dry and cephalopod remains were stored in alcohol in vials. Prey parts were identified to the lowest taxonomic level using a compound microscope, reference collection, and species identification keys. Fish otoliths and cephalopod beaks were measured using calipers or ocular micrometer. These measurements were used to estimate prey size from published regression equations. Data were entered on paper datasheets in the identification laboratory and then transcribed into the database. |
