The establishment and population characteristics of the invasive blue crab Callinectes sapidus in the lagoon of Narta, Albania.


The aim of this study is to evaluate the establishment of blue crab population in Narta Lagoon, to monitor its distribution, to assess its abundance and to analyze its population structure and biometric characteristics. Comparative analyses were done between data collected in 2012 and those collected during 2014 - 2015. Blue crab individuals were collected from gillnets and fyke nets of local fishermen. Abundance, carapace width and height, as well as weight of each collected individual have been evaluated. Questionnaires were also distributed to local fishermen, in order to gather additional information on the presence, state and impact of the blue crab to other populations of Narta Lagoon. Based on the collected data and analysis in this study, the population of the blue crab Callinectes sapidus can be considered as established in the Narta Lagoon.
