What are some parasites in the coral reef?
The main parasites that are found in or on reef fish are isopods and copepods, which are small crustaceans1. A famous example of parasitism on reefs is the tongue-eating louse of the species Cymothoa exigua.
How do humans Threate corals?
Local Threats to Coral Reefs Coral reefs face many threats from local sources, including: Physical damage or destruction from coastal development, dredging, quarrying, destructive fishing practices and gear, boat anchors and groundings, and recreational misuse (touching or removing corals).
What is coral Outplanting?
Outplanting, or planting coral fragments grown in nurseries back onto reefs, is a type of restoration activity. Photo Credit: NOAA/Kelli O’Donnell. The NOAA Coral Reef Conservation Program is working with partners on various restoration activities.
Are there coral reefs in Sri Lanka?
Nearly all of Sri Lanka’s reefs are located within 40 km from the coast and they contribute significantly to the marine fish production (Rajasuriya and White, 1995). Figure 1. Important recorded coral reef areas in Sri Lanka.
Is coral bleaching caused by humans?
Increased greenhouse gases from activities like deforestation, and the burning of fossil fuels for heat and energy, cause ocean temperatures to rise, change storm patterns, and contribute to sea level rise. These changes lead to more coral bleaching events, increased storm destruction, and more.
How long is coral restoration?
As many as 25% of all the fish in the sea depend on coral reefs for their survival. It can take 25 years to regrow a coral reef.
Is Sri Lanka good for snorkelling?
Apart from its pristine beauty, Sri Lanka has come into the limelight for its exotic snorkeling spots which are ideal for exploring the world underwater. The cost of snorkeling in Sri Lanka is not too high as well.
What is the biggest coral reef in Sri Lanka?
The Bar Reef
The Bar Reef, located 2 km off the coast of Kalpitiya, is in fact the largest coral reef and the largest protected marine area in Sri Lanka. While it was declared a marine sanctuary in 1992, the reef remained relatively unexplored or otherwise affected by human activity due to the then ongoing civil war.
What kind of parasites are in the ocean?
Some of the most common parasites include skin crawlers (copepods), tongue biters or ‘doctors’ (isopods), ectoparasitic flukes (monogeneans), endoparasitic flukes (digeneans), round worms (nematodes), tapeworms (cestodes) and spiny headed worms (acanthocephalans) – to name a few!
Can you get a parasite from the ocean?
In addition to pools and hot tubs, it is possible to get the infection from any type of “recreational” water including lakes, rivers, and the ocean.
What happens if we lose our coral reefs?
If coral reefs disappeared, essential food, shelter and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer as a consequence. Marine food-webs would be altered, and many economically important species would disappear.
Can bleached coral survive?
When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality. In 2005, the U.S. lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event.
