Between 1992 and 1999, US commercial fishing vessels averaged 78 deaths per year. The main contributors to fatalities are:<br /><br /> * inadequate preparation for emergencies<br /> * poor vessel maintenance and inadequate safety equipment<br /> * lack of awareness of or ignoring stability issues.<br /><br />Many fishermen, while accepting that fishing is dangerous, staunchly defend their independence. Many proposed laws and additional regulation to increase safety have been defeated because fishermen oppose them.<br /><br />Alaska's commercial fishermen work in one of the world's harshest environments. They endure isolated fishing grounds, high winds, seasonal darkness, very cold water, icing, and short fishing seasons, where very long work days are the norm. Fatigue, physical stress, and financial pressures face most Alaska fishermen through their careers. The hazardous work conditions faced by fishermen have a strong impact on their safety. Out of 948 work-related deaths that took place in Alaska during 1990-2006, one-third (311) occurred to fishermen. This is equivalent to an estimated annual fatality rate of 128/100,000 workers/year. This fatality rate is 26 times that of the overall U.S. work-related fatality rate of approximately 5/100,000 workers/year for the same time period.Fishermanhttp://www.blogger.com/profile/06513006151163786047noreply@blogger.com0tag:blogger.com,1999:blog-494752429744724857.post-69260543409791131622009-01-24T23:56:00.001-08:002009-01-25T00:02:01.342-08:00History<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAPDpPJUoZSJH3BDtH-eTlH0djNtVwK-_PLeoMs3-_hEq5XHT1eoKqG0uQ6mXdBe-GxEbXZqFnI1gkicu81yMTPfhoHyQzq_MRpdmFV47W_4LzZt5vOY7wwDkAnNPPUmjMw4ITUKGqL6c/s1600-h/fishing.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 180px; height: 108px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAPDpPJUoZSJH3BDtH-eTlH0djNtVwK-_PLeoMs3-_hEq5XHT1eoKqG0uQ6mXdBe-GxEbXZqFnI1gkicu81yMTPfhoHyQzq_MRpdmFV47W_4LzZt5vOY7wwDkAnNPPUmjMw4ITUKGqL6c/s320/fishing.jpg" alt="" id="BLOGGER_PHOTO_ID_5295137250218633906" border="0" /></a>Fishing has existed as a means of obtaining food since the Mesolithic period. By the time of the Ancient Egyptians, fishermen provided the majority of food for Egyptians. Fishing had become a major means of survival as well as a business venture. Fishing and the fisherman had also influenced Ancient Egyptian religion; mullets were worshiped as a sign of the arriving flood season. Bastet was often manifested in the form of a catfish. The method Amun, in ancient Egyptian literature, created the world, is associated with the Tilapia's method of mouth-brooding.Fishermanhttp://www.blogger.com/profile/06513006151163786047noreply@blogger.com0tag:blogger.com,1999:blog-494752429744724857.post-85268869828860635092009-01-24T23:52:00.000-08:002009-01-25T00:21:14.150-08:00Commercial fishing<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgML5bmceEOkVdF50ik0Gsfqgju8DcqstrGiWoojs-jvf2DdJ1j9w1CxDi5UZMQzMBJsC6ZYxVvK6JCLACkGMA1NJQ1o1OSf_yEU-W0D1JGbNdCs2ZAqdEBtaDRPDVlf9df58I-cdWpo0s/s1600-h/fun_fishing.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 158px; height: 105px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgML5bmceEOkVdF50ik0Gsfqgju8DcqstrGiWoojs-jvf2DdJ1j9w1CxDi5UZMQzMBJsC6ZYxVvK6JCLACkGMA1NJQ1o1OSf_yEU-W0D1JGbNdCs2ZAqdEBtaDRPDVlf9df58I-cdWpo0s/s320/fun_fishing.jpg" alt="" id="BLOGGER_PHOTO_ID_5295136776356895362" border="0" /></a>According to the FAO, there were 38 million commercial and subsistence fishermen and fish farmers in 2002, more than triple the number in 1970. Of this total, 74% worked in capture fisheries and 26% in aquaculture. The total fishery production of 133 million tonnes equated to an average productivity of 3.5 tonnes per person.[2]<br /><br />Most of this growth took place in Asian countries, where four-fifths of world fishers and fish farmers dwell.<br /><br />Most fishermen are men involved in offshore and deep-sea fisheries. Women fish in some regions inshore from small boats or collect shellfish and seaweed. In many artisanal fishing communities, women are responsible for making and repairing nets, post-harvest processing and marketingFishermanhttp://www.blogger.com/profile/06513006151163786047noreply@blogger.com0tag:blogger.com,1999:blog-494752429744724857.post-36442459987825975982009-01-24T23:51:00.001-08:002009-01-25T00:21:33.967-08:00Mercury contentFish and shellfish have a natural tendency to concentrate mercury in their bodies, often in the form of methylmercury, a highly toxic organic compound of mercury. Species of fish that are high on the food chain, such as shark, swordfish, king mackerel, albacore tuna, and tilefish contain higher concentrations of mercury than others. This is because mercury is stored in the muscle tissues of fish, and when a predatory fish eats another fish, it assumes the entire body burden of mercury in the consumed fish. Since fish are less efficient at depurating than accumulating methylmercury, fish-tissue concentrations increase over time. Thus species that are high on the food chain amass body burdens of mercury that can be ten times higher than the species they consume. This process is called biomagnification. The first occurrence of widespread mercury poisoning in humans occurred this way in Minamata, Japan, now called Minamata disease.<br /><br />The complexities associated with mercury transport and environmental fate are described by USEPA in their 1997 Mercury Study Report to Congress. Because methylmercury and high levels of elemental mercury can be particularly toxic to unborn or young children, organizations such as the U.S. EPA and FDA recommend that women who are pregnant or plan to become pregnant within the next one or two years, as well as young children avoid eating more than 6 ounces (one average meal) of fish per week.<br /><br />In the United States the FDA has an action level for methyl mercury in commercial marine and freshwater fish that is 1.0 parts per million (ppm), and in Canada the limit for the total of mercury content is 0.5 ppm. The Got Mercury? website includes a calculator for determining mercury levels in fish.<br /><br />Species with characteristically low levels of mercury include shrimp, tilapia, salmon, pollock, and catfish (FDA March 2004). The FDA characterizes shrimp, catfish, pollock, salmon, and canned light tuna as low-mercury seafood, although recent tests have indicated that up to 6 percent of canned light tuna may contain high levels.Fishermanhttp://www.blogger.com/profile/06513006151163786047noreply@blogger.com0tag:blogger.com,1999:blog-494752429744724857.post-54538746029144259842009-01-24T23:50:00.001-08:002009-01-25T00:02:01.344-08:00Fish productsToday, fisheries are estimated to provide 16% of the world population's protein, and that figure is considerably elevated in some developing nations and in regions that depend heavily on the sea. The flesh of many fish are primarily valued as a source of food; there are many edible species of fish. Other marine life taken as food includes shellfish, crustaceans, sea cucumber, and jellyfish. Roe are also harvested.<br /><br /><span style="font-weight: bold;">Fish may also be collected live for research observation or for the aquarium trade</span>.<br /><br />Fish and other marine life have uses apart from food. Pearls and mother-of-pearl are valued for their lustre. Traditional methods of pearl hunting are now virtually extinct. Sharkskin and rayskin which are covered with, in effect, tiny teeth (dermal denticles) were used for sandpaper. These skins are also used to make leather. Sharkskin leather is used in the manufacture of the hilt of traditional Japanese swords. Sea horse, star fish, sea urchin and sea cucumber are used in traditional Chinese medicine. Tyrian purple is a pigment made from marine snails Murex brandaris and Murex trunculus.<br /><br />Sepia is a pigment made from the inky secretions of cuttlefish. Fish glue is made by boiling the skin, bones and swim bladders of fish. Fish glue has been valued for its use in products from illuminated manuscripts to the Mongolian war bow. Isinglass is a substance obtained from the swim bladders of fish (especially sturgeon), it is used for the clarification of wine and beer. Fish emulsion is a fertilizer emulsion that is produced from the fluid remains of fish processed for fish oil and fish meal.Fishermanhttp://www.blogger.com/profile/06513006151163786047noreply@blogger.com0tag:blogger.com,1999:blog-494752429744724857.post-73034717863098993292009-01-24T23:49:00.000-08:002009-01-25T00:02:01.345-08:00TechniquesThere are many techniques for fishing. Fishermen may use hooks and fishing line and a fishing rod.Fishing nets, fish traps, and trap nets may be used to capture fish. Lobster and crab pots use a similar method. Hand fishing consists of fishing with the hands or through the use of minimal equipment. In spear fishing, the fish is killed using an ordinary spear or a specialized variant thereof. Closely related to spear fishing is bow fishing. Trained animals can assist in fishing; one notable example is Asian cormorant fishing.<br /><br />Kite fishing allows the fisherman to cast far into the water, even without a boat. Dredging is sometimes used to scoop scallops or oysters from the seabed. Poisonous plants can be used to stun fish so that they become easy to collect by hand; cyanide can also be used. Other fishing techniques include electrofishing and dynamite fishing. Bottom trawling, seining, driftnetting, handlining, longlining, gillnetting and diving are widely used techniques. A recent non-traditional approach using a radio-controlled boat is called remote control fishing.Fishermanhttp://www.blogger.com/profile/06513006151163786047noreply@blogger.com0tag:blogger.com,1999:blog-494752429744724857.post-29839966841046646182009-01-24T23:48:00.000-08:002009-01-25T00:02:01.346-08:00Understanding Fishing ActivityFishing is the activity of catching fish. Fishing techniques include netting, trapping, angling (including trolling) and hand gathering. The term fishing may be applied to catching other aquatic animals such as different types of shellfish, squid, octopus, turtles, frogs, and some edible marine invertebrates. Fishing is not usually applied to catching aquatic mammals such as whales, where the term "whaling" is more appropriate, or to commercial fish farming. In addition to providing food through harvesting fish, modern fishing is both a recreational and professional sport.[citation needed]<br /><br />According to FAO statistics, the total number of fishermen and fish farmers is estimated to be 38 million. Fisheries provide direct and indirect employment to an estimated 200 million people. In 2005, the worldwide per capita consumption of fish captured from wild fisheries was 14.4 kilograms, with an additional 7.4 kilograms harvested from fish farms.Fishermanhttp://www.blogger.com/profile/06513006151163786047noreply@blogger.com0
