Historically, industrial fishers avoided coral because their nets would get caught on the reefs. In the 1980s, "rock-hopper" trawls attached large tires and rollers to allow the nets to roll over rough surfaces. Fifty-five percent of Alaskan cold-water coral that was damaged by one pass from a bottom trawl had not recovered a year later.
Deep-water coral Paragorgia arborea and a Coryphaenoides fish at a depth of 1,255 m (4,117 ft) on the Davidson Seamount. The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond 2,000 metres (6,600 ft) where water temperatures may be as cold as 4 °C (39 °F).

A diversity of corals. Coral reef protection is the process of modifying human activities to avoid damage to healthy coral reefs and to help damaged reefs recover. The key strategies used in reef protection include defining measurable goals and introducing active management and community involvement to reduce stressors that damage reef health.
Coral reefs are important buffers between the land and water and help to reduce storm damage and coastal erosion. [2] They provide employment, recreational opportunities and they are a major source of food for coastal communities. [2] It is estimated that $375 billion dollars come from ecosystem services provided by coral reefs each year. [3]
