Prawn Pandalus borealis

Using aqueous extracts of a dried shrimp, Sergestes lucens and a fresh prawn, Pandalus borealis, Take et al. (37) examined organoleptically the role of various constituents in the make-up of their taste. The results are summarized as follows. 

The prawn Pandalus borealis changes its body color by means of movable pigment granules. The neurosecretory octapeptide blanching hormone (Table 30-5) controls the process. This is a member of a larger family of peptide hormones with related functions such as the 18-residue pigment-dispersing hormone of the fiddler crab and similar hormones in insects. ... 

Salmon farm Wild salmon contains predominantly the (3S,3 S)-enantiomer. In fanned salmon, fed with shrimp bran, which is mainly produced from northern prawn (Pandalus borealis) or with an extract from the green alga Haematococcus pluvialis, the (3S,3 S)-enantiomer is also the main enantiomer. However, if the astaxanthin comes from the basidiomycetous yeast Phaffia rhodozyma or its sexual form Xanthophyllomyces dendrorhous, or from the Antarctic krill (Euphausia superba), the (3R,3 R)-enantiomerprevails.
