Fisheries

A fishery can be defined as an entity involved in the raising of fish through aquaculture or the harvesting of wild fish in oceans, seas and freshwater. Humans have relied on aquatic resources for sustenance and survival for centuries yet with the advent of improved fishing vessels, techniques, tools, and equipment as well as technology coupled with growing demands for resources, the rate of exploitation has reached unprecedented rates raising fears about the inevitable collapse of aquatic ecosystems. Rapacious techniques such as bottom trawling or use of large nets modify marine ecosystems by physically altering habitats, reducing biodiversity and disrupting food chains. There is also a growing concern that fisheries have reached their global maximum potential as many valuable fish stocks have already been depleted, leading to the exploitation of less valuable fish.

International Food Security Assessment: 2012-22 Last Updated on 2014-10-26 16:56:26   Food security is estimated to improve slightly in 2012 as the number of food-insecure people in the 76 countries covered in this report declines from 814 million in 2011 to 802 million in 2012. The share of the population that is food insecure remains at 24 percent. Over the next decade, the share of the population that is food insecure is projected to decline from 24 percent in 2012 to 21 percent in 2022, but the number of food insecure people is projected to increase by 37 million. Regionally, food insecurity is projected to remain most severe in Sub-Saharan Africa. Food-insecure people are defined as those consuming less than the nutritional target of roughly 2,100 calories per day per person. The U.S. Department of Agriculture's Economic Research Service (ERS) has, since the late 1970s, reported annually on food security in a number of developing countries. A key... More »
National Oceanic and Atmospheric Administration (NOAA), United States Last Updated on 2014-06-30 19:00:15 The National Oceanic and Atmospheric Administration (NOAA) is a federal agency within the United States Department of Commerce.  As a science-based operational agency tasked with monitoring climate and changes in the environment, NOAA is responsible for the study of the atmosphere and the oceans.  The agency issues daily weather forecasts and storm warnings, restores coastline, aids the flow of marine commerce, and manages fisheries.  NOAA's activities facilitate weather- and climate-sensitive economic activity that account for roughly one-third of the country's gross domestic product (GDP)[1]. The agency also responds to natural and man-made maritime disasters, operates a complex network of oceanographic, meteorological and atmospheric data-collecting products and services, and manages marine mammals, marine endangered...

Common coral reef fishes of Bimini Last Updated on 2014-06-18 16:33:48 Bimini is an island in the  Bahamas  in the West Indies.  Over 320 species of reef fishes have been identified during REEF Fish Surveys in Bimini. The following ranking is based on the results of 1672  REEF Fish Surveys covering a bottom time of 1552 hours and 11 minutes. (REEF Geographic Zone Report.  June 4, 2009).  The species are ranked by the percentage of surveys in which a species was observed.  Abundance of fishes in REEF Fish Surveys are estimated using the following categories: 1- single =1 individual, 2-few = 2- 10 individuals, 3-many = 11-100 individuals, and 4-abundant > 100 individuals.        The mean numeric abundance (ranging from 1 - 4) was calculated for each species..  The mean abundance category is determined as follows: mean abundance category 0...
