Ming-Tsung Chung et al. report a method for estimating field metabolic rate (FMR) in teleost fishes using the isotopic composition of carbon found in inner ear structures called otoliths. They show that their method can provide accurate estimates of FMR for free-ranging wild fishes and allows for tracking FMR of individual fish over time.
