Photo-Identification field and laboratory protocols utilizing FinBase Version 2.

Abstract

Marine mammal photo-identification surveys are conducted for multiple reasons that include estimating or evaluating abundance, survival, spatial and temporal habitat use, social structure and/or health. Surveys are performed along set tracklines in designated survey areas. When animals are sighted during a survey they are digitally photographed with an effort to capture images of all animals in a sighting for individual identification. Additionally, ancillary data and observations of the animals are recorded onto datasheets. The data obtained is then entered into FinBase, a customizable database system for managing photo-identification catalogs. These protocols were designed for small boat based dolphin photo-identification surveys, but can be utilized for any type of photo-identification surveys. Since FinBase is customizable the user can make changes to fit the needs of their specific survey. All the data and cropped images collected from photo-identification surveys can be stored in and managed with FinBase. Using the cropped images a catalog of individuals can be created and structured based on the attributes assigned to each animal. Within FinBase the user can track the sighting history of each individual, mother and calf relationships, and known associates of the individual.
