Fork length was measured in two groups of salmon parr (32–139 mm, frozen in a straight posture and frozen in a curved posture) before (L 1 ) and after (L 2 ) freezing and thawing. All the fish shrank. The decrease in length was significantly greater in the curved fish than the straight fish. The absolute reduction in length (L 1 –L 2 ) was related directly to L 1 , whereas the percentage reduction in length [(L 1 –L 2 )/L 1 × 100] was related inversely to L 1 .
