Larval Enhancement — Bayahibe

Published as: Assisted fertilization of threatened Staghorn Coral to complement the restoration of nurseries in Southeastern Dominican Republic | Technique: Larval Enhancement | Genera: Acropora | Method: Gametes were collected at spawning in situ, using traps placed over colonies. Gametes from genetically distinct colonies were mixed ex situ, and fertilised eggs removed and kept in 12L buckets. four types of substrates were introduced into buckets as larval stage was reached: 1) cleaned rock (year 1), 2) conditioned cement block 3) red cement block, 4) white cement block The water in buckets was replaced daily. Half the polyps were placed in aquaria, with wave makers and artificial light after … | Survival of transplants reported by the source: 10% | Post-restoration monitoring: 11 months | Authors' conclusion: Fertilization and settlement rates were 90% and 50%, respectively. The highest mortality occurred in the first 30 days, and was 10% at the end of 11 months. | Lessons reported: The procedure complements A. cervicornis restoration efforts in coral nurseries. This manuscript presents a detailed outline for restoration practitioners and managers, who can use assisted fertilization to increase genetic diversity within nurseries, as well as outplants to increase species recovery, or use assisted fertilization to increase reproductive success for sexually mature colonies. | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work. No contribution to the condition index is recorded: the source reports survival of transplanted material, which is not a measure of ecosystem condition.

Recorded result

No result recorded yet. A result is recorded when the project moves to Paused, Completed or Discontinued.

A variable shows "pending" instead of a contribution when no domain area has been set for it yet — the share of the world a project touched cannot be computed without one. The health percentages are accurate regardless.
