Moshenko January 1980 Canadian Data Report of Fisheries & Aquatic Sciences No.175 • Canadian Data Report of Fisheries and Aquatic Sciences These reports provide a medium for filing and archiving data compilations where little or no analysis is included . Such compilations commonly will have been prepared in support of other journal publications or reports. The subject matter of Data Reports reflects the broad interests and policies of the Department of Fisheries and Oceans, namely, fisheries management, technology and development, ocean sciences, and aquatic environments relevant to Canada. Numbers 1-25 in this series were issued as Fisheries and Marine Service Data Records. Numbers 26-160 were issued as Department of Fisheries and the Environ ment , Fisheries and Marine Service Data Reports. The current series name was changed with report number 161.
