Overview

Randomized trial explores larval settlement strategies in mesophotic octocorals, suggesting key factors for restoration efforts.

Key Points

  • This study investigates the spawning and larval settlement preferences of mesophotic octocorals to aid restoration efforts.
  • Collected octocoral fragments from Texas to Florida (2021-2023).
  • Analyzed spawning periodicity, egg development, and larval behavior.
  • Evaluated larval settlement rates and substrate preferences.
  • High fertilization rates throughout spawning in both species.
  • Larvae preferred tiles with crustose coralline algae, indicating substrate preference.
  • Survival was evident within days of presence on substrates, with some larvae surviving up to 2 months without settlement.
