Blacktip reef shark are found along the outer slope of the reef. Three sea turtles which have been categorized threatened visit the coral reef: the hawksbill turtle, green turtle, and olive ...
Kayankerni coral reef is a typical shallow reef with an average length of around roughly 2.5 km (1.6 mi) along the coast at the southern end of the Vandalous Bay. [2] The waters within the territories of the reef is measured on an average depth of within 1 and 1.5 m (3 ft 3 in and 4 ft 11 in) whereas the outer ends of the reef is remarkably measured at 6–7 m (20–23 ft).
The decline of fish populations has been accompanied with reducing numbers of pearl oyster, gorgonian coral, and acorn worm. Local fishermen rely on the reef to feed their families, but destructive fishing methods combined with the stress of pollution and coral mining have meant both nearshore and offshore catches have decreased.
Location of Sri Lanka. Environmental issues in Sri Lanka include large-scale logging of forests and degradation of mangroves, coral reefs and soil. Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Overfishing and insufficient waste management, especially in rural areas, leads to ...
Coral aquaculture, also known as coral farming or coral gardening, is the cultivation of corals for commercial purposes or coral reef restoration. Aquaculture is showing promise as a tool for restoring coral reefs, which are dying off around the world. [1] [2] [3] The process protects young corals while they are most at risk of dying. Small ...
The annual fish catch is 2,000 to 5,000 tonnes from the Lakshadweep islands, which is mostly constituted by tuna (about 70%) and shark. Perches, halfbeaks, Carangidae, needlefish and rays are also caught near the reefs. Shrimp, Achelata [1] and small fish, such as Sprattus, Pomacentridae and Apogonidae are widely used as a bait by the Laccadive ...
