A dinoflagellate-like parasite in Alaskan spot shrimp Pandalus platyceros and pink shrimp P. borealis Theodore R. Meyersl, Donald V. ~i g h t n e r * , Rita M. ~e d r n a n~ '~l a s k a ABSTMCT: Similar dinoflagellate-like organisms were observed histologically in spot shrimp Pandalus platyceros and pink shrimp P borealis from Yakutat and Prince William Sound, Alaska, USA, respectively. Infection in spot shrimp caused chalky white musculature, described as 'milky' by local fishers.

Ultrastructurally, the organism in the spot shrimp differed morphologically from the bitter-crab-syndrome dinoflagellate described for Alaskan Tanner crabs Chionoecetes bairdi and C. opilio, and Hematodinium perezi described from various crab species in marine waters off Europe and the southeastern United States. Our results suggest that the agent is undescribed and infects 2 species of pandalid shrimp.
