...resources of Bangladesh emphasizing the coastal environment, capture fisheries and management issues relative to the sector. Bangladesh’s Exclusive Economic Zone (EEZ) covers an area of about 166 000 km2. This area has abundant natural resources such as fish, shrimps, crabs and other marine products. Shrimp and fish trawling is the most important economic activity in this area. The fishery sector makes a significant contribution to the national economy in terms of foreign exchange, income generation and employment. It is very important in nutrition, especially in providing animal protein. In 1997 - 99, the marine fisheries sector contributed 22% of the total fishery production of 1 373 000 t. However, the resources are being destroyed in many ways. The fisheries resources have declined and fishers are getting poorer. The decline is partly due to estuarine set bag net, push net, and beach seine fishing, which result in recruitment over-fishing. A multiplicity of factors adversely affect the coastal fishery resources of Bangladesh. Various laws, ordinances and acts have been formulated to manage the fisheries resources and to protect the coastal zone environment. Most of the laws have been amended to meet current needs. However, marine fisheries...

Porter's Diamond of National Advantage

...Porter's Diamond of National Advantage (Part I) Classical theories of international trade propose that comparative advantage resides in the factor endowments that a country may be fortunate enough to inherit. Factor endowments include land, natural resources, labor, and the size of the local population. Michael E. Porter argued that a nation can create new advanced factor endowments such as skilled labor, a strong technology and knowledge base, government support, and culture. Porter used a diamond shaped diagram as the basis of a framework to illustrate the determinants of national advantage. This diamond represents the national playing field that countries establish for their industries. The complete Porter’s Diamond system (Porter, 1998, pg 127) The individual points on the diamond and the diamond as a whole affect four ingredients that lead to a national comparative advantage. These ingredients are: The availability of resources and skills, Information that firms use to decide which opportunities to pursue with those resources and skills, The goals of individuals in companies, The pressure on companies to innovate and invest. The points of the diamond are described as follows: I. Factor Conditions A country creates its own important factors such as skilled resources and technological base. The stock of factors at a given time is less important than the extent that they are upgraded and deployed. Local disadvantages in factors of production force...

...Crustaceans (Crustacea) form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 67,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by the nauplius form of the larvae. Most crustaceans are free-living aquatic animals, but some are terrestrial (e.g. woodlice), some are parasitic (e.g. Rhizocephala, fish lice, tongue worms) and some are sessile (e.g. barnacles). The group has an extensive fossil record, reaching back to the Cambrian, and includes living fossils such as Triops cancriformis, which has existed apparently unchanged since the Triassic period. More than 10 million tons of crustaceans are produced by fishery or farming for human consumption, the majority of it being shrimp and prawns. Krill and copepods are not as widely fished, but may be the animals with the greatest biomass on the planet, and form a vital part of the food chain. The scientific study of crustaceans is known as carcinology (alternatively, malacostracology, crustaceology or crustalogy), and a scientist who works in carcinology is a carcinologist...

Case in Point

...CASE STUDY: HOW HUMANS HAVE AFFECTED THE ANTARCTIC FOOD WEB Although the icy waters around Antarctica may seem an inhospitable environment, a complex food web is found there. The base of the food web consists of microscopic, photosynthetic algae present in vast numbers in the well-lit, nutrient-rich water. A huge population of herbivores—tiny shrimp like krill—eat these marine algae. Krill, in turn, support a variety of larger animals. A major consumer of krill is the baleen whale, which filters krill out of the frigid water. Baleen whales include blue whales, humpback whales, and right whales. Squid and fishes also consume krill in great quantities. These, in turn, are eaten by other carnivores: toothed whales such as the sperm whale, elephant seals and leopard seals, king penguins and emperor penguins, and birds such as the albatross and the petrel. Humans have had an impact on the Antarctic food web as they have had on most other ecosystems. Before the advent of whaling, baleen whales consumed huge quantities of krill. Until a global ban on hunting large whales was enacted in 1986, whaling steadily reduced the number of large baleen whales in Antarctic waters. As a result, of fewer whales eating krill, more krill became available for other krill-eating animals, whose populations increased. Now that commercial whaling is regulated, it is hoped that the number of large baleen whales will slowly increase, and that appears to be the case for some species. However, the populations...

Marine Fungi; a Review

...Marine Mycology: An Overview of Pathogens, and Secondary Metabolites Introduction and History The golden age of marine mycology occurred from 1960-1990 with the research and discovery of most of the roughly 500 species of obligate marine fungi. Much of said research was conducted from 1980-2000; this 30 year period saw the report of nearly half of the marine fungal species currently known (Jones et al. 2009; Jones, 2011). That being said, marine fungi are vastly understudied and under rated in comparison to marine plants, animals, and other microorganisms; frequently they are omitted or only briefly referenced in marine biodiversity and ecology text books (Jones and Pang, 2012). The cladistics of marine fungi is currently in a state of flux, with new taxa being discovered as molecular techniques such as DNA and RNA analysis via polymerase chain reactions, and gel electrophoresis are implemented (Ald et al 2005). Even though fungus-like organisms such as oomycetes are not fungi, marine mycologists often study them as they perform similar functions, and until recently most had been classified as fungi based on their morphological similarities (Jones, 2011). These fungus-like organisms are eukaryotic, heterotrophic, zoospores, have chitin containing cell walls, and similar life cycles to fungi (Neuhauser et al. 2012). Conventionally terrestrial or freshwater species are also included in the marine fungal group as facultative species; this is due to their active ecological...

Living Coastal Resources

...LIVING COASTAL RESOURCES OF THE ASEAN REGIONAND DATA REQUIREMENTS FOR THEIR MANAGEMENT SIGNIFICANCE OF LIVING COASTAL RESOURCES Living coastal resources are found within major coastal ecosystems consisting of coral reefs, mangroves, seagrass beds, benthic systems, and estuaries or lagoons. Coastal ecosystems, particularly estuaries and inshore marine waters have the highest rate of primary production as compared to terrestrial and oceanic regions. Daily gross production rate in terms of grams of dry organic matter per square metre area for the narrow coastal band ranges from 10 to 25, with all other regions having substantially lower values (2). The coastal band conveniently thought of as the transition area between land and sea, holdsthis great diversity of ecosystems, each characterized by its own unique ecological feature. Conditions here may be harsh with wide fluctuations in temperature and salinity, but because of the abundance of food supply, these areas can and do support a high diversity of species which have become efficiently adapted to the widely fluctuating environmental conditions. These ecosystems remain productive because of tidal action which circulates food and nutrients rapidly and efficiently and at the same time washes away waste materials. They also serve as efficient nutrient traps of the continuous nutrient input washed down from land. Within these ecosystems, the autotrophic and heterotrophic layers are maintained in close contact so that energy transfer...

Bp Explosion

...spill, triggered by the April 20 explosion of the Deepwater Horizon rig: THE SCALE OF THE CATASTROPHE "This is probably the biggest environmental disaster we have ever faced in this country," top White House energy adviser Carol Browner said on Sunday. "There could be oil coming up 'til August." Browner told CBS's "Face The Nation," "We are prepared for the worst." Louisiana, the nearest state to BP's gushing undersea well that is 42 miles out in the Gulf of Mexico, has been the most impacted by the spill so far. Louisiana Governor Bobby Jindal said this week that more than 100 miles of Louisiana's 400-mile coast had so far been impacted by the spilled oil. State officials have reported sheets of oil soiling wetlands and seeping into marine and bird nurseries, leaving a stain of sticky crude on cane that binds the marshes together. Billy Nungesser, president of Plaquemines Parish, saw dying cane and "no life" in parts of Pass-a-Loutre wildlife refuge. "Oil debris", in the form of tar balls and surface "sheen", has also been reported coming ashore since the April 20 accident in outlying parts of coastal Mississippi and Alabama. In the week of May 17, Coast Guard officials found tar balls on some beaches in the Florida Keys, raising fears that the so-called Loop Current that runs from the Gulf of Mexico through the Florida Straits may have already brought oil from the spill far to the southeast. But laboratory tests subsequently showed the tar balls were not from the BP spill...

It is also an example of a protected mark, serving as inspiration and a viable model to several other products and product groups from Jamaica. In addition to this qualitative rationale for the industry, coffee contributes to the Jamaican economy, grown in a region with full employment, something very few geographical areas are able to boast. In addition to its social contribution there is significant export potential that may be realised from both increased production and export volume, increased value of export by expanding the percentage of value added production locally, as well as development of value-added products. It is argued that the sector has negatively impacted the natural environment and is likely to continue doing so, however, farm practices have improved with increased utilisation of natural fertilisers and pesticides.

Turtles

...The biology of the sea turtle and facors affecting its population Upon first sight of the great sea turtle it might just think that it is like any other turtle. The truth is that marine turtles are beautiful creatures spending a majority of their lives wandering endlessly through our massive ocean. These reptiles have the ability to do amazing things. Some of these things include evolving to a range of purely innate responses to the demands of a changing suite of environments and having remarkable navigations skills for their excursions that may last up to several years. Sea turtles have been in existence for more than 100 million years and researchers have been studying them for great deal of time. During the past 20 years however, the natural history of marine turtles has received growing attention and much has been learned (Bjorndal 19). Instantly you will fall in love with their beauty and majestic way of life. The biology behind these amazing animals causes them stand out from much of the ocean life. There are seven different species of sea turtles. These species include Kemps Ridley, Flatback, Loggerhead, Olive Ridley, Leatherback, Hawksbill, and the Hawaiian Green Turtle (Gardner 2004). Unlike many animals the female sea turtle is generally larger than the males. The main distinction between the two is that the male tends to have a longer tail. The core part of the sea turtle and the part that helps protect them from predators is the shell. The shell grows around the...

Arctic Ocean

...shield covering the back part of an animal) and has laterally compressed bodies. Basically, Amphipods are shrimp –like in form. Copepods are animals that also belong to phylum Arthropoda but to a different class Maxillopoda. They are usually 1 to 2 millimeters long, with a cylindrical body and rounded head with large antennae. Their body, including their armored exoskeleton, is so small and so thin that it is almost transparent. Because of their size, they have no need for a circulatory system and of course, a heart. These two organisms are very important in the food chain in the Arctic Ocean because they concentrate the protein and fatty acids from phytoplankton, bacteria, and in extreme cases, from dead animals, into a nutritious package that is consumed by the marine animals especially in the Arctic region. 9. List down the findings of the 4 experts in the Arctic Ocean? 1. Majority of the ice in the Arctic Ocean is comparatively thin (less than 2 meters). 2. The underside of the ice enters a series of depressions, which causes it to melt from underneath. 3. The team discovered the old history of whaling in Svalbard. 10. Make a 10 line conclusion based on the findings of the expedition. Give its implications to the environment. The ice caps in the Arctic Ocean are becoming thinner than it should be mainly because of global warming. Based from recent studies, ice that is two meters thick is likely to survive the heat of the summer. But as the explorers have discovered...
