在斯里蘭卡，研究人員發現與天然珊瑚礁相比，沉船為珊瑚和魚類提供了更多不同的微生境結構。當地很多沉船已有近一個世紀的歷史，為魚類提供食物和安全的棲息環境，更有較高密度的魚群，但棲息於沉船的魚群與天然珊瑚礁的種類有異。研究人員希望從這些沉船案例學習，並幫助日後人工珊瑚礁的保育工作。近年當地亦把一些舊巴士丟棄在海洋希望作保育用途，但生態學家認為，並非所有材料都適合，有些可能會造成污染，而且選擇合適的地點也很重要。
In Sri Lanka, researchers discovered shipwrecks provide more complex structures for corals and fish compared to natural coral reefs. Many of these shipwrecks are nearly a century old, providing food and safety for fish and have higher fish density, but the fish communities on these wrecks can be varied compare to natural reefs. researchers hope to learn from these sites and help develop artificial reefs to support marine communities. old buses were dumped in the ocean for fish breeding in the recent years, but ecologists warn not all materials are suitable as some might become pollution, and that selecting the right location is also very important.
