“…The fi rst information about the occurrence of blue crab in Montenegro, specifi cally in Port Milena, comes from a personal observation in 2006 [10]. The fi rst verifi ed record dates back to 2013, when two males were caught with a gill net in Boka Kotorska bay, while the fi rst female was discovered in 2017 in the lagoon of the Tivat Solila nature reserve [11]. This study addresses the population characteristics of blue crab using common tools such as morphometrics, length to weight ratio and sex ratio.…”

The Atlantic blue crab, Callinectes sapidus, is a highly invasive species that poses a significant threat to Mediterranean ecosystems. In the last two decades, it has become established in several marine and estuarine areas of the eastern Adriatic Sea, resulting in a decline in commercial catches and damage to fishing gear. This article reviews the current status of blue crab invasion in Montenegro and Croatia and analyses its abundance and population structure. Overall 619 crabs were sampled (male:female ratio, 1:1.91). Both carapace width and weight differed significantly between males and females, with males having a wider carapace and more weight. There was a significant difference in carapace width and weight among sites. For the total population, the mean male and female carapace width was 130.3 ± 30.8 and 108.8 ± 41.4 mm, respectively. In addition, the mean male and female weight was 187.2 ± 85.6 and 132.5 ± 39.1 g, respectively. Coefficient b between the weight and carapace width of blue crabs was significant at all locations, although it varied between males and females. This work will also document the impacts of the blue crab invasion on local ecosystems and provide comprehensive overview of populations structures and shed light on this important aspect of blue crab ecology.
