It is the habitat for over 500 species of fish, more than 350 species of mollusks, and also to protected or endangered species, such as the manatee, the marine turtle, the whale shark, and acroporid corals, commonly known as elkhorn and staghorn corals.

Fisheries provide food to all the populations of these countries and are the primary source of employment for local fishermen. The fisheries in the MAR, such as lobster, halibut, conch, and snapper, among others, are important at local, regional and international levels. Additionally, the reef structure is the first barrier protection for the coast, because it absorbs up to 99 percent of the wave energy from surges, storms, and hurricanes. 10 TRAINING GUIDE FOR CORAL REEF RESTORATION 1.3 Threats to the MAR The spectacular beauty of the MAR landscape 5.

  • The Benefits and Risks of Aquacultural Production for the Aquarium Trade
    Aquaculture 205 (2002) 203–219 www.elsevier.com/locate/aqua-online The benefits and risks of aquacultural production for the aquarium trade Michael Tlusty * Edgerton Research Laboratory, New England Aquarium, Central Wharf, Boston, MA 02110, USA Received 15 February 2001; accepted 2 May 2001 Abstract Production of animals for the aquarium hobbyist trade is a rapidly growing sector of the aquacultural industry, and it will continue to become more important as restrictions are placed on collecting animals for the wild. Currently, approximately 90% of freshwater fish traded in the hobbyist industry are captively cultured. However, for marine ornamentals, the reverse is true as only a handful of species is produced via aquaculture technology. Given the future importance of aquaculture production of ornamental species, it is important to elucidate the benefits and risks for this sector. Thus, here the production of ornamental species is compared to the production of food species. The most notable difference is that the marine coastal environment is not currently utilized in the production of ornamental species. Thus, public opposition will not be as great since there is no direct impact on the marine environment. In assessing the benefits and risks of ornamental aquaculture production, the cases where further development should and should not be pursued are developed. In general, aquaculture production of ornamental species should be pursued when species are difficult to obtain from the wild, breeding supports a conservation program, there is some environmental benefit or elimination of environmental damage via the breeding program, or to enhance the further production of domesticated species. Aquaculture production of ornamental species should be avoided when it would replace a harvest of wild animals that maintains habitat, a cultural benefit, or an economic benefit.

  • Coral Amendment 3
    3/30/95 AMENDMENT 3 TO THE FISHERY MANAGEMENT PLAN FOR CORAL AND CORAL REEFS OF THE GULF OF MEXICO INCLUDING AN ENVIRONMENTAL ASSESSMENT REGULATORY IMPACT REVIEW AND INITIAL REGULATORY FLEXIBILITY ANALYSIS April 1995 Gulf of Mexico Fishery Management Council Lincoln Center 5401 West Kennedy Boulevard Suite 331 Tampa, Florida 33609-2486 This is a publication of the Gulf of Mexico Fishery Management Council pursuant to National Oceanic and Atmospheric Administration Award No. NA57FC0004. SUMMARY: Amendment 3 with supplementary documents was prepared by the Gulf of Mexico Fishery Management Council to provide additional management to the harvest of live rock in the Gulf of Mexico. Live rock is an assemblage of living marine organisms attached to a hard substrate such as dead coral or limestone. Amendment 2, implemented December 21, 1994, established area closures, vessel trip limits, gear restrictions, permits for harvest and aquaculture, restricted access, a phase-out of harvest by 1997, and a redefinition of octocorals. This amendment considers further live rock regulation including an annual quota during phase- out, revision of trip limits, closed area off Florida's Panhandle, redefinition of allowable octocorals, and limited personal use harvest.

  • Common Conditions in Freshwater Aquarium Fish Fish Are the Largest and Most Species-Rich Group of Vertebrates, Numbering 60,229 Species and Subspecies
    WILDLIFE and EXOTICS | FISH ONLINE EDITION Common conditions in freshwater aquarium fish Fish are the largest and most species-rich group of vertebrates, numbering 60,229 species and subspecies. Given there is such a plethora of species, fish have adapted to a wide range of aquatic environments – from the oceans to desert puddles, and from deep-sea hydrothermal vents to glacial mountain lakes and streams (Weber, Sonya Miles 2013).

Moreover, it also was not clear to what extent precipitation in an anaerobic reactor can be tolerated because adequate knowledge on the structure and quality of methanogenic sludges with high calcium carbonate content was lacking. In this thesis, the feasibility of anaerobic treatment of waste waters with a high calcium content was investigated. The development of high ash content anaerobic sludges was studied under varying conditions of biomass yield, precipitating quantities of CaC03 and particle size of the seed sludge. The location of CaCOa precipitation, within the aggregates or in the bulk solution, appeared to be an important factor determining the quality of high ash content sludges.
