Table 1 Trophic position of Nephrops in Clew Bay (2014), based on δ13C and δ15N isotopic signatures from different time periods represented by long-term storage tissues (muscle: ‘Spring long’ and ‘Summer long’) and short-term storage tissue (hepatopancreas: ‘Spring short’ and ‘Summer short’). See Table 2 for relevant time periods.
