The relationship between first vertebra width and body length of Atlantic salmon differs between parr and smolts
The relationship between the width of the first vertebra ( W V ) and the fork length ( L F ) of Atlantic salmon differs between parr and smolts. The previous use of the first vertebra to reconstruct the diets of predators from the bone remains of ingested prey will have underestimated the size of sm...

| Summary: | The relationship between the width of the first vertebra ( W V ) and the fork length ( L F ) of Atlantic salmon differs between parr and smolts. The previous use of the first vertebra to reconstruct the diets of predators from the bone remains of ingested prey will have underestimated the size of smolts and probably also their frequency of occurrence in the diet. Using the ratio W V :L F provides potential for differentiating between intact parr, smolts and pre‐smolts in the diet. |
