The article describes the results of study on a group (sub-population) of the
red king crab, an invasive species, in Dalnezelenetskaya Bay in July 2014. Egg
bearing females were the most abundant at the study site. Both the number of
crabs with injured legs and the share of crabs with old shells were lower than
in 2013. The total stock of red king crab was calculated to be 3850 specimens.
In 2014, the number of juveniles was higher and the number of old males was
lower in comparison to the levels of 2013.
