Overview

Findings reveal correlations of growth and metabolic rates in fish, suggesting trade-offs in energy use.

Key Points

  • This research aims to investigate how metabolic rates and growth patterns change within individual teleost fish during their development.
  • Measured body mass and metabolic rates of 389 fish over an average of 6.6 times per individual.
  • Analyzed data from seven different fish species to examine scaling patterns.
  • Employed longitudinal measures to assess ontogenetic changes.
  • Found a positive correlation between the scaling of maintenance metabolic rates and growth within individuals.
  • Identified a negative correlation between scaling of aerobic scope and growth.
  • Demonstrated that faster ontogenetic growth may limit metabolic capacity for additional functions beyond maintenance.
