A shrimp survey was conducted in Chatham Sound (PFMA 3 and 4) from September 13-18, 2015 primarily to inform shrimp stock assessment in the Prince Rupert District (PRD). Nass/Skeena Eulachon have been assessed by COSEWIC as a species of special concern and the Eulachon Technical Committee of the Skeena Area Marine Research Collaboration group identified the need for additional Eulachon data. Thus, biological sampling of Eulachon was conducted during the survey, including tissue sampling to be used to genetically determine stock composition. Eulachon were observed in all 42 tows and comprised 12.48% of the cumulative catch by weight. A bi-modal length-frequency distribution confirms two dominant Eulachon age classes were present in Chatham Sound. Microsatellite analysis indicates that 45.6% of the fish sampled originated from the Nass/Skeena system with 45.6% representing Eulachon from Central Coast populations. Continued monitoring of Eulachon dynamics in this area is important to inform the recovery potential of this at-risk species"--Abstract. |
