Summary

Trap color significantly impacts catch per unit of effort (CPUE) for nine-spined stickleback. Galvanized traps yielded 81% more fish than black traps, highlighting trap design importance in fisheries studies.

Area of Science:

  • Fisheries Science
  • Ichthyology
  • Ecology

Background:

  • Limited understanding of catch per unit of effort (CPUE) variation in stickleback fisheries.
  • Factors influencing CPUE in nine-spined stickleback (Pungitius pungitius) remain largely unknown.
  • Investigating the impact of trap models on CPUE is crucial for accurate fisheries assessments.

Purpose of the Study:

  • To determine how different minnow trap models affect CPUE for nine-spined stickleback.
  • To compare the effectiveness of two visually similar trap types in capturing stickleback.
  • To identify potential biases in fisheries data collection due to trap variations.

Main Methods:

  • Paired experimental design comparing two minnow trap models side-by-side.
  • Simultaneous fishing of galvanized and black trap types in the same environment.

  • Quantification of catch per unit of effort (CPUE) for each trap type.

    • Main Results:

    • Galvanized traps (mean CPUE = 1.31 fish/h) significantly outperformed black traps (mean CPUE = 0.20 fish/h).
    • Galvanized traps consistently yielded higher catches, averaging 81% more fish than black traps.
    • Trap color demonstrated a substantial influence on the efficiency of fish capture.

    Conclusions:

    • Minor variations in trap appearance, such as color, can dramatically affect CPUE.
    • Findings have significant implications for the design and interpretation of fish abundance and occurrence studies using minnow traps.
    • Standardization of trap models is recommended to minimize bias in fisheries research and monitoring.
