... For instance, it is possible that exceptional feeding conditions in Southeast Alaska may allow fish to grow both gonadally and somatically, whereas that may not occur for NSS Atlantic herring. It is also possible that the shorter migrations of Sitka Sound Pacific herring (based on limited studies of Southeast Alaska stocks; Rounsefell, 1930;Rounsefell and Dahlgren, 1933;Dahlgren, 1936;Carlson, 1980;Csepp et al., 2011) allow for a smaller reduction in somatic growth compared to reductions in somatic growth from energetically costly migrations for NSS Atlantic herring (Slotte, 1999b). As scales for this study were collected in a single year, it is possible that unusual environmental influences may have limited the reduction in growth for maturing Sitka Sound Pacific herring in 2017 (such as small first year gonads in response to poor feeding conditions), whereas NSS Atlantic herring scale collections made over many years moderated year-specific environmental influences thereby revealing differences in growth between immature and mature fish. ...
