A method to reconstruct anguilliform fishes from partially digested items

Estimating the amounts of resources consumed by individuals is important in many studies. For predators, allometric relationships can be used to extrapolate the size of preys from undigested remains found in the stomach and in the faeces. However, such equations are available for a limited number of species. Based on a large sample size gathered in New Caledonia on both predators (sea kraits) and their preys (anguilliform fishes), we provide the first allometric relationships that allow estimating accurately the mass and the size of various anguilliform fish species.

We warmly thank the Aquarium de Nouméa, the Direction des Ressources Naturelles de la Province Sud and the IRD de Nouméa for logistical support. We are especially grateful to F. Devinck, C. Goiran, D. Ponton, E. Potut. S. Lorioux helped during fieldwork. B. Seret helped to identify the fishes. T.R. Cook corrected the English. Rex Cambag tested the quality of the alcohol. The study was carried out under permits # 6024-179/DRN/ENV and # 6024-3601/DRN/ENV.
