The document summarizes a presentation about the environmental effects of overfishing in the Great Barrier Reef. It notes that overfishing is one of several threats to the reef, along with pollution, climate change, and coral bleaching. While fishing generates over $1 billion annually for Australia's economy, overfishing is unsustainable and can damage marine life and coastal communities that rely on fish. The presentation calls for increased awareness of overfishing issues and encourages sustainable practices to protect the Great Barrier Reef for future generations.
The document discusses threats facing coral reefs from human activities such as global warming, pollution, overfishing, and tourism. It notes that 70% of corals are threatened or destroyed, coral reefs have high biodiversity similar to rainforests, and 75% of fish are overfished. Human waste from cruise ships and other threats endanger coral reefs. The document calls on readers to help protect coral reefs through conservation efforts in their local communities and beyond.
Coral reefs are diverse underwater ecosystems known as the "rainforests of the sea." They occupy less than 1% of the ocean but support 25% of marine species and have an annual global economic value of $375 billion. Coral reefs protect coastlines from erosion, create habitats, sequester carbon, and provide resources for tourism, fishing and medicine. However, they face many threats including pollution, coastal development, warming oceans, overfishing, and damage from ships and divers. Countries and organizations have established protections for coral reefs including marine sanctuaries, regulations on collection and trade, and management plans, but continued conservation efforts are needed to sustain these fragile ecosystems.

This document discusses coral reefs and their importance. It notes that coral reefs have an extremely high biodiversity and provide many benefits including tourism, fisheries, and shoreline protection worth over $164 million annually in Tobago. However, coral reefs are fragile ecosystems that are threatened by rising temperatures, pollution, sedimentation and other human impacts. In 2005, a major bleaching event killed 66% of hard corals on Buccoo Reef in Tobago and subsequent monitoring found partial mortality of 32.5% and total mortality of 6.6% by 2006. Conservation efforts are needed to protect these valuable ecosystems.
Coral reefs are formed by colonies of tiny animals called polyps that have a symbiotic relationship with algae. Though they cover less than 1% of the ocean, coral reefs are home to 25% of marine species and have potential medical benefits. However, coral reefs are threatened by human activities such as pollution and dynamite fishing as well as climate change. When stressed, corals expel the algae living in their tissues, causing them to bleach and often die. Efforts to preserve coral reefs include cryopreservation and lab regeneration before returning corals to the ocean.
Coral reefs are biologically rich ecosystems that support billions of people but are increasingly threatened by pollution, invasive species, disease, bleaching, and climate change. In response, the U.S. established the Coral Reef Task Force in 1998 to map, monitor, research the causes of degradation, and promote conservation of coral reefs. The Task Force and NOAA work to fulfill the goals of the Coral Reef Conservation Act of 2000 to protect these valuable ecosystems.

Importance of coral reefs & its propertiesDr. sreeremya S
As these corals grow and die, they leave behind their calcium carbonate skeletons. On these skeletons, other corals grow. As the year’s passes, walls of coral begin to form: massive walls of rock (Kleypas, 1999).
As the waves and currents beat upon these reefs, nooks, crannies, ledges and caverns form in these walls. Just as there are different types of corals, there are different types of coral reefs. The three major types of reefs are fringing reefs, barrier reefs and atolls(Langdon,2000).Like coral reefs , sponges are also a wonderful resource, which has immense applications (Sreeremya et al.,2018).
The Great Barrier Reef is the largest coral reef system in the world, located off the coast of Australia. It is home to thousands of plant and animal species but is endangered due to threats like climate change, pollution, overfishing, and natural disasters. Conservation efforts include the Great Barrier Reef Marine Park Authority, which manages the reef, and plans like the Reef Water Protection Plan and Biodiversity Strategy that aim to protect water quality and preserve species diversity in the reef.
Coral reefs are diverse underwater ecosystems made up of calcium carbonate structures secreted by coral polyps. They support enormous biodiversity and provide goods and services valued at $30 billion annually, including fisheries that support one billion people and tourism that generates billions for economies like those of Florida and Australia. However, coral reefs are severely threatened by bleaching due to rising water temperatures, pollution, sedimentation, poison fishing, and careless tourism. Conservation efforts include supporting marine protected areas, reducing plastic use, and inspiring others to protect coral reefs for future generations.

Coral reef and fisheries habitat restoration in the coral trianglebayuvita
The document discusses the degradation of coral reefs in the Coral Triangle region and the need for large-scale restoration efforts. It notes that 95% of coral reefs in the region are severely damaged and losing ecosystem functions. Conservation alone is not enough to preserve reefs and dependent species as habitat has been destroyed. Active restoration is needed on a large scale through training local communities and students in restoration techniques to revive fisheries and protect coastlines from hazards.
Coral reef and fisheries habitat restoration in the coral trianglebayuvita
The document discusses coral reef and fisheries habitat restoration in the Coral Triangle region. It states that 95% of coral reefs in the region are severely damaged and restoration is needed to maintain fisheries, shore protection, and biodiversity. While some conservation efforts have been made, restoration has not received sufficient funding and needs to be prioritized to sustain the ecosystems and communities that depend on them. Traditional and newer restoration techniques exist but require more investment in training and large-scale application.
The document summarizes the importance of coral reefs to the global economy and environment, and discusses efforts to study and monitor coral reef health in the Turks and Caicos Islands. The School for Field Studies has established a research center on South Caicos to collect long-term data on the local reef system. Researchers use methods like fish surveys and coral bleaching assessments to evaluate the condition of reefs over time. Preliminary results show the reefs have approximately 15% live coral cover dominated by star corals and sea rods. Healthier reefs farther from shipping channels indicate human impacts. Continued monitoring is needed to understand climate change effects on the fragile reef ecosystems.
The Massachusetts Oyster Project aims to restore oyster reefs in Boston Harbor to improve water quality by filtering pollutants. They conducted a pilot project placing 100,000 oyster seeds in the Charles River and saw a 50% survival rate after 6 months. Their goals are to continue monitoring the pilot site, establish more reefs, and help perpetuate the oyster species and their benefits to the harbor ecosystem.
Presentation on status of Oceanic Blue Carbon science and knowledge gaps. Presented at the Global Ocean Commission's High Seas Symposium, 12 November 2015.
The document summarizes the current state of coral bleaching on the Great Barrier Reef. It describes how coral bleaching occurs when algae are expelled from coral due to stressors like heat waves. This year, record high ocean temperatures caused the worst mass bleaching event on the Great Barrier Reef. 50% of corals died in northern areas. The bleaching is part of the impacts of human-caused climate change and rising ocean temperatures. The document ends by highlighting some organizations working to help protect the reef through sustainable practices and fundraising.
Apo Reef Natural Park is a protected marine area located off the coast of Occidental Mindoro, Philippines. It consists of three islands covering a total area of 27,469 hectares, including a 15,763 hectare marine area. The park supports diverse ecosystems like mangroves, beaches, and coral reefs which are home to over 385 fish species and threatened species like sea turtles and dolphins. Visitor numbers and revenues have been increasing in recent years, demonstrating the park's potential for ecotourism through activities such as scuba diving, snorkeling, and bird watching.
A coral reef is an underwater ecosystem characterized by reef-building corals. Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet. They:
• protect coastlines from the damaging effects of wave action and tropical storms
• provide habitats and shelter for many marine organisms
• are the source of nitrogen and other essential nutrients for marine food chains
• assist in carbon and nitrogen fixing
• nutrient recycling.

Coral reef Threats, conservation and Restoration.pptxVIRENDRA KUMAR
Coral reefs are some of the most diverse ecosystems in the world. About 25% of the ocean's fish depend on healthy coral reefs. Unfortunately, coral reef ecosystems are severely threatened. Some threats are natural, such as diseases, predators, and storms. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. Saving and restoring the world's coral reefs requires a multi-pronged approach that ranges from the local to the global level.
The document discusses threats from climate change to the Great Barrier Reef, including increasing ocean temperatures causing coral bleaching and algae growth. This decreases biodiversity and damages the reef ecosystem. Climate change also threatens the reef through declining water quality and decreased marine tourism. Efforts are underway by groups like the Great Barrier Reef Foundation to address these challenges and protect the reef through fundraising, volunteer opportunities, education, and research.

87. Results: Slow but steady progression of yellow band disease 2007 January April July October
88. Conclusions The total percent cover of live hard coral on Tobago’s reefs is low, at an average of 17.55% with no significant change over the three years of study. Both Bulldog and Cove Reef have the lowest amount of live coral (5%) and high macroalgal cover (over 40%), while dead coral composes the rest of the reef. These two sites are down current from Scarborough, the main town in Tobago, and are affected by land-based sources of silt and pollution.
89. Conclusions The sediment that settles on the study reefs is coming from land. Monitoring stations situated far away from the coast such as Sisters Rocks, had a low sedimentation rate, less than 0.5 gram of dry weight per month, while other study sites like Little Englishman’s Bay had over 60 grams per month. Three reefs showed increase in live hard coral such as Spiny Colony in Speyside, Plymouth and the Buccoo Reef.
90. Conclusions Six reefs had no change over the three year study: Bulldog Reef (off Scarborough), Sisters Rocks, Arnos Vale, Mount Irvine, Blackjack Hole (Speyside), and Little Englishman’s Bay. Four reefs lost live coral cover: Cove reef close to Scarborough, North Point off Charlotteville and Culloden. Kariwak lost more than half of its live coral in 3 years. The most prevalent coral disease is Yellow Blotch Disease (YBD), which was found in 9 of the 13 monitoring stations infecting Montastraea faveolata
91. Recommendations We recommend the implementation of policies that address coastal sediment by minimizing soil erosion from agriculture, deforestation and construction. These should include more rigorous procedures for planning and the issuing of Certificates of Environmental Clearance that require the applicant to take steps to prevent mud from entering coastal waters (e.g. the use of sediment traps on construction sites, seeding exposed soil with grass). All domestic and industrial wastewater should be treated before reaching the sea, or if this is not feasible, diverted to outfall pipes that discharge far from the coastline, in deep water with strong currents.
92. Recommendations We also recommend the creation of new marine protected areas (MPAs) around Tobago. These MPAs should focus on areas of healthy coral and include areas where fishing activities are restricted, in order to increase populations of herbivores (e.g., parrotfish) which are critically important to the recovery and resilience of coral reefs after bleaching or disease outbreaks (Mumby et al., 2006). MPAs are also known to benefit fisheries and tourism, as they act as fish replenishment reserves where commercially important species of fish and shellfish (e,g, groupers, snappers, lobster) are allowed to grow and reproduce while also providing an attraction for divers and snorkelers.
93. Recommendations Monitoring programs on coral reefs provide information about the status of these ecosystems and can help to observe changes over time. They can also indicate the factors that have negative impact on the reefs and make suggestions on how to solve them. With this information, policymakers can take action to solve the issues before is too late. Therefore, it’s recommended to continue monitoring coral reefs in Tobago so everyone can be informed about what happens afterwards, and if there is any improvement in the ecosystem. The Reef-check protocol is a very simple and economic way to keep gathering valuable data and should be adopted and applied indefinitely in Tobago.
