Biological Harvest is the collection of living things from the ecosystem for recreation, consumption, or sale of marine products. Boring sponges bore into the calcium carbonate skeleton of coral. Complex habitat and resources reflects the complex architecture of sessile, plant-like organisms, such as octocoral and sponges, which provides shelter and protection for small fish and other invertebrates from predators. Contact Uses, such as biological additions, physical damage, and biological harvesting, are activities in which humans create pressures through direct contact with the ecosystem. Coral is a colonial marine animal consisting of polyps. Cultural services are the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, recreational opportunities, aesthetic experiences, sense of place, and educational and research opportunities. Discharge limitations are responses to regulate and control the discharge of pollutants and the use of chemicals. Discharges are the intentional or unintentional distribution of chemicals, debris, or other pollution, into the environment as a consequence of human activities. Ecosystem monitoring and restoration refers to responses to directly alter the condition of the reef ecosystem through restoration or remediation activities, setting limits on degradation through biological criteria or water quality criteria, or improving knowledge through monitoring, mapping, and scientific research. Ecosystem services are the benefits people obtain from ecosystems . Encrusting sponges grow on top of the coral. Nutrient and contaminant processing refers to an ecosystem's ability to process and cycle contaminants and nutrients through its system. Nutrients are essential elements needed by plants and animals for growth and primarily include nitrogen, phosphorous, and potassium, as well as minor nutrients such as calcium, magnesium, or zinc. The Reef Ecosystem includes a suite of abiotic variables that form the physical and chemical environment. Pressures are human activities that create stress on the environment. Provisioning services are the products or ecosystem goods obtained from ecosystems, including seafood, genetic and biochemical resources, pharmaceuticals, ornamental resources, and water resources. The state of the Reef Ecosystem is the condition, in terms of quantity and quality, of the abiotic and biotic components including physical, chemical, and biological variables. Reef Habitat is the abundance, distribution, and condition of the benthic components of the reef ecosystem. Reef Inhabitants are all of the motile components of the reef ecosystem, including fish, invertebrates, marine reptiles and mammals, and are quantified by their abundance, distribution, and condition. Reef Life is the abundance, distribution, and condition of the biological components of the coral reef ecosystem. Resource use management pertains to responses to regulate or limit contact activities that may directly impact coastal species through harvesting or physical damage. Responses are actions taken by groups or individuals in society and government to prevent, compensate, ameliorate or adapt to changes in Ecosystem Services or their perceived value. Sediment includes dirt, sand, silt, clay, and small rocks that form soil on land or soft substrate in marine habitats, and may be transported by water, wind, or human activities. Socio-Economic Drivers include the sectors that fulfill human needs for Food & Raw Materials, Water, Shelter, Health, Culture, and Security, and the Infrastructure that supports the sectors. Sponges are sessile colonial animals with soft porous bodies supported by a fibrous skeletal framework. Supporting services are ecological processes that indirectly benefit humans by maintaining a functional ecosystem for the production of other ecosystem goods and services. Toxics are chemical pollutants that are poisonous, carcinogenic, or otherwise directly harmful to humans, plants, or animals. Tube, barrel, and finger sponges have vertical morphologies.

CMap Description

Sponges provide complex habitat and resources for fish and other invertebrates. Boring sponges may erode coral skeletons. Encrusting sponges may damage coral by growing over their surface, but can also help bind the reef, facilitate recruitment of crustose coralline algae, and contribute to reef structural strength. Nutrient and contaminant processing by sponges and wetlands can improve water quality and reduces human exposure to contaminants. Sponges may be harvested for household uses, aquariums, or ornamental resources. Sponges also provide aesthetic value, contributing to recreational opportunities for snorkelers and scuba divers. Sponges are a source for natural products (pharmaceutical, neutraceuticals, and cosmetics). Natural products are often derived from secondary metabolites found either in the sponges themselves or in their symbiotic microorganisms. Pollution and harvesting can affect survival and growth of sponges. Monitoring and scientific research can be used to track the condition and abundance of sponges, and to understand interactions with other species. Resource use management may be used to protect endangered species or limit harvesting.

Economic Markets & Policy: Regulate International Trade of Reef Species Many coral reef species are harvested internationally for a variety of markets including the aquarium trade, food, curios, jewelry and pharmaceuticals. The US is the largest importer for many of these markets. The US strictly limits extraction of stony coral and many reef species in its waters; but as a major importer and consumer of coral reef species, more actions can be taken to decrease the demand on international imports. Setting and enforcing regulations on what can be imported (such as Convention on International Trade in Endangered Species CITES) is one approach that has been taken. More information is needed, leaving room to collect trade data and assess the impacts of extraction techniques to find sustainable methods. Demand for species collected this way will be increased with greater transparency to consumers, which can be accomplished through certifications for environmentally cognoscente collectors and those using alternatives like aquaculture and coral farming. Continued participation in Asia Pacific Economic Cooperation (APEC) and International Coral Reef Initiative (ICRI) is also beneficial. U.S. Coral Reef Task Force. 2000.

Monitor & Research: Research Artificial Reef Siting, Size, and Materials Impact for Future Management Decisions The effects of artificial reefs on fish and invertebrate abundance and community composition and on other sanctuary resources need to be assessed. Siting and size considerations should include spatial components such as nearest natural reef, species connectivity, currents, distance to shore, expected use, hurricane occurances, etc. The longevity of artificial reefs composed of different materials needs to be evaluated and considered heavily.

Resource Use Management: Seasonal Fisheries and Harvesting Finfish and shellfish stocks may be more or less susceptible to fishing pressures during certain times of the year. This may be due to seasonality of recruitment and/or changes in food/predation pressures. If fishing restrictions may be more successful if this seasonality is taken into consideration and fishing pressure adjusted accordingly.

Florida Keys National Marine Sanctuary Regulations, Federal Register § Volume 66, Number 11 (2001). NOAA established the Tortugas Ecological Reserve (a no-take zone) in the Tortugas region (Tortugas or region) of the Florida Keys to protect significant coral resources and to protect an area that serves as a source of biodiversity for the Sanctuary as well as for the southwest shelf of Florida. Establishment of the Reserve included expansion of the Sanctuary boundary to ensure that the Reserve protects sensitive coral habitats lying outside the existing boundary of the Sanctuary.

Application to Coral Reefs:The Regulation protects significant coral resources and many marine species by providing a no-take zone.

Legislative Actions:The regulation increased the no-take zones to 24 areas. Fishing is prohibited in Tortugas north for areas that are within State waters. Diving is prohibited in Tortugas south.
