redOrbit Staff & Wire Reports - Your Universe Online It has been found that an unevenness of nutrients in reef waters can increase the bleaching vulnerability of reef corals according to Research from the University of Southampton and the National Oceanography Centre, Southampton. Numerous polyps jointly forming a layer of living tissue that cover the calcareous skeletons make up the corals. Single-celled algae called zooxanthellae, which live within the coral polyps, is what they...

Growing populations have established themselves at distant points in...
In the long term, the industry will benefit from measures taken to prevent overfishing, such as the license buyback scheme. This scheme will have broad ranging implications for industry revenue. It may reduce the number of establishments given the paucity of licenses, but it also may allow larger catches with fewer operators, increasing economies of scale and possibly make those companies that remain more profitable. For these reasons, industry research firm IBISWorld has added a report on...
April Flowers for redOrbit.com - Your Universe Online An international team of researchers recently rated every coastal nation on their contribution to the health of the world's oceans. The United States rated just above average, with food provision, tourism and recreation identified as leading concerns. The report, published in the journal Nature, gave each nation a score between 0-100 in ten separate categories like clean water, biodiversity, food provision, carbon storage, coastal...
BOSTON, NEW YORK and WASHINGTON, Aug. 15, 2012 /PRNewswire/ -- Conservation International, The National Geographic Society, the New England Aquarium and the Pacific Life Foundation today unveiled the Ocean Health Index, the first comprehensive measure of ocean health for 171 coastal regions worldwide. (Logo: http://photos.prnewswire.com/prnh/20120815/NY58138LOGO ) The new index is a quantitative measure of ocean health that considers human beings as part of the ocean's ecosystem....
'High microcystin concentrations occur only at low nitrogen-to-phosphorus ratios in nutrient-rich Canadian lakes' Nutrient pollution, one of the greatest threats to our freshwater resources, is responsible for the algal blooms that blanket our lakes and waterways in summer months. Large blooms of cyanobacteria ('blue green algae') can cause fish kills, increase the cost of drinking water treatment, devalue shoreline properties, and pose health risks to people, pets, and wildlife. A new...
The growth of aquaculture market is playing its role in bridging the gap between demand and supply of fishery industry products. (PRWEB) August 12, 2012 From ancient times, fishing from oceans, lakes and rivers has been a major source of food, provider of employment and other economic benefits for humanity. However, for nearly 4 decades, the dramatic increase of pollution, abusive fishing techniques worldwide, and illegal, unreported and unregulated fishing, has resulted in declining fish...
Study by Wildlife Conservation Society and University of the Azores identifies additional risks to reefs stemming from pollution and heavy fishing Microbes, sponges, and worms—the side effects of pollution and heavy fishing—are adding insult to injury in Kenya's imperiled reef systems, according to a recent study by the Wildlife Conservation Society and the University of Azores. The authors of the study have found that pollution and overfishing on reef systems have an ecological...
Most people think of seafood as either wild or farmed, but in fact both categories may apply to the fish you pick up from your grocery store. In recent years, for example, as much as 40 percent of the Alaskan salmon catch originated in fish hatcheries, although it may be labeled "all wild, never farmed." An article produced by a working group of UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) recommends that when a combination of seafood production...
redOrbit Staff & Wire Reports - Your Universe Online In the journal Global Change Biology, a worldwide study is published to understand and forecast the likely impact of ocean acidification on shellfish and other marine life living in seas from the tropics to the north and south poles. Ocean acidification is occurring because some of the increased carbon dioxide humans are adding to the atmosphere dissolves in the ocean and reacts with water to produce an acid. According to the...

Synaptula lamperti is a species of sea cucumber that can be found in the waters of the Indo-Pacific. Its range includes the coastal waters of Papua New Guinea, the Philippines, Indonesia, and Micronesia. It does not have the tube feet, which are common to other species of sea cucumber, instead moving around by using a small grouping of pinnate feeding tentacles, which are always moving. It can also move by using the small, hook-like bones found along its body, attaching itself to the sea...
Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...
Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...
The little tunny is found widespread in temperate and tropical waters of the Atlantic Ocean, Black Sea and Mediterranean Sea. It is the most common tuna and is highly migratory, with a range from Cape Cod, Massachusetts to Brazil in the Western Atlantic. In the Eastern Atlantic it is found from Skagerrak to South Africa. The little tunny will form schools close to the shoreline, around inlets, and sandbars that can cover up to two miles. This fish prefers warm water and will migrate south in...
This harmless shark is native to the Pacific Ocean off the coast of Indonesia, it is also found in coastal waters from Japan to India. It lives on the ocean floor in shallow areas around coral reefs, hiding during the day and feeding at night. In Taiwan and Madagascar the whitespotted bamboo shark is used for food. Occasionally this species is kept in home aquariums as pets. The young whitespotted bamboo shark will have a black body covered with white and light blue spots and dark vertical...
