Series forms part of National Sea Products fonds and consists of records relating to the fishing operations of National Sea Products and its predecessors. Includes records of fishing vessels that did business with the company and fishing trip inventories that detail the species and amount of fish purchased and processed. The vessel records consist of ledgers and journals for individual schooners and trawlers, 1900-1938, that include names of owners, shareholders, amount of expenses and profits, and often, individual payments for catches. The fishing trip records consist of trip sheets, one set arranged by vessel name, 1927-1952 (including such well known trawlers as Cape LaHave and Cape North), and the other set arranged by date, 1945-1950. The sheets record the amount and species caught, and fishermen's share amounts each trip. There are also daily fish inventories of catches received at the Lunenburg Sea Products plants and subsequent shipments of fresh, frozen and salt fish, 1927-1954. Also includes 24 b&w copy prints with negatives, depicting fishing trawlers of the Maritime National Fish Company fishing for cod, 1933.
