An image analysis technique was examined to assess its ability to estimate automatically the carapace length of shrimp (Pandalus borealis). Carapace length, pixel area, and weight were measured in a sample of 285 shrimp. An accurate slide calliper was used to measure the carapace length (13–30 mm) by an experienced operator with a precision (standard deviation) of 0.2 mm. A high-resolution still image camera was used to produce an 181
