Implication

Explores environmental influences on recruitment variability in narrow-barred Spanish mackerel, suggesting management strategies for stock rebuilding.

Key Points

  • The study aims to understand how environmental conditions affect recruitment variability in the narrow-barred Spanish mackerel fishery.
  • Analyzed long-term age composition data over 24 years
  • Reconstructed year class strength using generalized additive models
  • Identified key environmental indices influencing recruitment variability
  • Generalized additive models explained 76%-84% deviance in year class strength
  • Key environmental factors included flooding events and sea surface temperatures
  • Hindcast recruitment variability provided insights into historical fishery fluctuations
