Maximum sedimentation rates that can be tolerated by different corals range from 400 mg cm −2 d −1. Turbidity and sedimentation also reduce the recruitment, survival and settlement of coral larvae. Fine sediments tend to have greater effects on corals than coarse sediments. Increased sedimentation can cause smothering and burial of coral polyps, shading, tissue necrosis and population explosions of bacteria in coral mucus. The duration that corals can survive high turbidities ranges from several days (sensitive species) to at least 5–6 weeks (tolerant species). Some individual coral species can tolerate short-term exposure (days) to suspended-sediment concentrations as high as 1000 mg L −1 while others show mortality after exposure (weeks) to concentrations as low as 30 mg L −1. Minimum light requirements of corals range from 100 mg L −1 in marginal nearshore reefs.
Coral polyps undergo stress from high suspended-sediment concentrations and the subsequent effects on light attenuation which affect their algal symbionts. Results of these investigations have provided a generic understanding of tolerance levels, response mechanisms, adaptations and threshold levels of corals to the effects of natural and anthropogenic sediment disturbances. Effects of sediment stress have so far been investigated in 89 coral species (∼10% of all known reef-building corals). The sensitivity of a coral reef to dredging impacts and its ability to recover depend on the antecedent ecological conditions of the reef, its resilience and the ambient conditions normally experienced. The risks and severity of impact from dredging (and other sediment disturbances) on corals are primarily related to the intensity, duration and frequency of exposure to increased turbidity and sedimentation. We hope you have an interest in our field of expertise so we can do business &develop a long term partnership.A review of published literature on the sensitivity of corals to turbidity and sedimentation is presented, with an emphasis on the effects of dredging.
