TECHNICAL NOTE A NEW, VOLUNTEER-BASED, COST EFFECTIVE METHOD FOR ZOOLOGICAL MAPPING: THE PHOTO IDENTIFICATION OF FRESHWATER CRAYFISH (CRUSTACEA: DECAPODA) SPECIES AND THE IMPORTANCE OF VOLUNTEERS IN CRAYFISH RESEARCH
The publication of the European Crayfish Atlas within the framework of the CRAYNET programme is a major breakthrough in Decapoda mapping in Europe. The current data base contains information from approximately 60-70% of the 50 km × 50 km squares covering the continent. A new method to improve t...

The publication of the European Crayfish Atlas within the framework of the CRAYNET programme is a major breakthrough in Decapoda mapping in Europe. The current data base contains information from approximately 60-70% of the 50 km × 50 km squares covering the continent. A new method to improve this situation further is the use of photo identification involving volunteers in the collection of distribution data. The crayfish identification ability of two potential user groups, astacologists and biology teachers/students, was tested using the questionnaire given in Figure 2. One picture (Astacus leptodactylus male) was correctly identified by everyone, the others were recognised by 59-94% (astacologists) and 30-88% (non-crayfish specialised biology teachers and students). The first European Decapoda photo identification survey proved that the necessary expertise exists in the continent to determine crayfish species from pictures and also that the quality of the pictures is less important than the presence of key details.
