Summary

Otolith mass asymmetry in fish, a key factor in acoustic function, is generally small (<5%) and stable throughout life. This finding impacts understanding fish behavior in altered gravity environments.

Area of Science:

  • Ichthyology
  • Bioacoustics
  • Gravitational Biology

Background:

  • Otolith mass asymmetry in fish can affect acoustic functionality and behavior, particularly in weightlessness.
  • Previous studies suggested asymmetry values can fluctuate significantly during a fish's lifetime.

Purpose of the Study:

  • To investigate the stability of otolith mass asymmetry throughout a fish's life.
  • To quantify otolith mass asymmetry in a diverse range of teleost fish species.

Main Methods:

  • Calculated a dimensionless measure of otolith mass asymmetry (chi).
  • Studied saccular otolith asymmetry in 59 Mediterranean teleost species, 14 Black Sea teleost species, red drum, and guppy.
  • Examined utricular otolith asymmetry in carp and goldfish.

Main Results:

  • The calculated asymmetry value (chi) was independent of fish size, systematic or ecological group, or otolith growth rate.
  • In most studied fish, saccular otolith asymmetry was small, with an absolute value less than 0.05 (or 5%).
  • Mathematical modeling suggests asymmetry values are stable within an individual fish's lifetime.

Conclusions:

  • Otolith mass asymmetry is generally small and stable in most teleost fish species.
  • This stability contrasts with previous hypotheses of significant lifetime fluctuations.
  • Findings are crucial for understanding fish sensory perception and behavior in altered gravity, including spaceflight.
