Constituents Of The Extracts Of A Marine Worm, Perinereis Brevicirrus

Abstract

As a preliminary study for identifying the attractant for prawns and fish, the aqueous ethanolic extracts of a marine worm, Perinereis brevicirrus, were analyzed for free and combined amino acids, nucleotides, organic bases, guanidino compounds, organic acids and sugars, and so far as nitrogenous constituents are concerned, their distribution in the extracts was made clear almost completely. The authors express here their sincere thanks to Dr. A. INOUE in the Naikai Regional Fisheries Research Laboratory for his kindness in obtaining the worm. © 1966, The Japanese Society of Fisheries Science. All rights reserved.
