| description | The presence of the signal crayfish, Pacifastacus leniusculus, in
waterbodies of Europe is of high concern due to its potentially major ecological impact on
invaded ecosystems and native crayfish. In this study, we examined population
characteristics and spatial dynamics of a recently established signal crayfish population
near the edge of its invasive range in the Mura river (Croatia), by analyzing population
density, fecundity, and sex and size structure, as well as movement patterns. The obtained
results revealed that the examined population is characterized by relatively low
population density, balanced sex and size structure of adult crayfish, and high spatial
activity of examined individuals, with an average daily movement of 28 m/day. Pleopodal
fecundity was in a similar range to other signal crayfish populations in Europe. The large
minimal size of caught mature females (85 mm total length), coupled with the estimated low
population density (0.8–1.2 crayfish.m-2), suggested that the examined
population has not reached its maximum density yet. Obtained results represent baseline
information for the development of monitoring procedures and management strategies aimed
at signal crayfish control within the Mura and Drava catchments and also highlight the
importance of understanding local factors controlling invasive species’ population
dynamics and productivity. |
