The pattern of stable isotope signatures in a sub‐sample of 67 juvenile weakfish Cynoscion regalis, captured at the mouth of the Christina River, 113 km upstream of the mouth of Delaware Bay (U.S.A) in the autumn of 2000, suggested that they resided at the location since recruitment. The possibility that young C. regalis departed from the generally characteristic life‐history pattern of marine migrants at this latitude, i.e . emigrating offshore with the adults in autumn was bolstered by the collection of 69 individuals during the winters of 2000–2006 from the travelling screens of a power plant located at river kilometre 88 including an 118 mm total length juvenile captured in mid‐February 2006.
