Shrinkage correction and length conversion equations for Theragra chalcogramma, Mallotus villosus and

chon Thaleichthys pacificus by freezing decreased fork length (LF) up to 18, 56 and 27 % and reduced mass by up to 84, 35 and 11%, respectively. Shrinkage of walleye pollock standard length (LS) was greater for fish in 95 % ethanol v. 5 % formalin and for fish in 10 % formalin v. frozen. Equations describing the shrinkage and loss in mass for these species are presented as well as conversions between different length measurements (LS, LF and total length, LT) for fishes that were frozen. # 2005 The Fisheries Society of the British Isles (No claim to original US government works) Key words: body mass loss; capelin; eulachon; length conversion; shrinkage; walleye pollock. Scientific research frequently requires preservation of samples collected in the field, and generally, preservation results in body shrinkage and loss of mas
