Crustacean Research is a peer-reviewed, open access journal that covers all fields of biology of crustaceans and their related taxa. This journal has been running for some time, but it is new to me. The former president of The Crustacean Society, Akira Asakura, is editor-in-chief.
The publication costs are quite reasonable for an open access journal. People who are not members of the Carcinological Society of Japan pay about US$30 per page if there is no colour on the page. $300 for a ten page paper compares very favourably to, say, PLOS ONE ($1,350).
It might be a good venue to submit research on Marmorkrebs!
