In this book, the authors present current research in the study of the evolutionary history, ecological significance and effects on dietary consumption of shrimp. Topics include the biology, morphology and antiviral defence of penaeid shrimp (Crustacea: decapoda); shrimp (penaeus monodon) farming in the coastal areas of Bangladesh; three analytical methods that employ ion chromatography coupled with conductivity detection for the determination of sulphiting agents, polyphosphates and organic acids in shrimps; movement and habitat use by the abundant seagrass shrimp Phycomenes zostericola (Decapoda: palaemonidae); and the availability of brine shrimp bioassay as a screening technique of allelopathic compounds.
