Fisheries and aquacultureLast Updated on 2014-12-07 21:08:51
In 2002 the global production from fishing and aquaculture combined reached about 133 million tonnes. The global yield from capture fisheries is stagnating, but aquaculture has been expanding.
The quantities of fish captured remained stable at about 93 million tonnes per year between 1999 and 2002. China and Peru are leading the top ten of countries with the largest catches. The same countries have remained in the top ten for over a decade.
Oceans and seas provide 90% of the world's fishery catches. During the past decade marine catches brought to land increased slightly compared to the preceding decade. It should be noted that the quantity of marine fish caught and discarded fell by several million tonnes in the same time period. Trends vary greatly across different regions and for different species. The species yielding the largest harvest is the Peruvian... More »
What Is Aquaculture?Last Updated on 2014-12-07 19:28:34
The term aquaculture broadly refers to the cultivation of aquatic organisms in controlled aquatic environments for any commercial, recreational or public purpose. The breeding, rearing and harvesting of plants and animals takes place in all types of water environments including ponds, rivers, lakes, the ocean, and man-made “closed” systems on land.
Aquaculture serves many purposes including:
Food production for human consumption;
Rebuilding of populations of threatened and endangered species;
Wild stock enhancement;
Production of baitfish; and
Fish culture for zoos and aquariums.
It is one of the fastest growing forms of food production in the world. Because harvest from many wild fisheries has peaked globally, aquaculture is widely recognized as an effective way to meet the seafood demands of a growing population.

International Food Security Assessment: 2012-22Last 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 StatesLast 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). 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...

Backyard pondLast Updated on 2014-06-25 17:01:23
A pond or water garden will likely become the focal point for all your backyard conservation.
Backyard ponds and water gardens are for birds, butterflies, frogs, fish, and you and your family. These ponds are typically small, sometimes no larger than 3 to 4 feet in diameter. They may be built in barrels or other patio containers. Water is effective in drawing wildlife to your backyard. It is also a natural, relaxing, and scenic addition that can provide interest and enjoyment.
Consider locating your backyard pond where you can see it from a deck or patio. Have it blend in with its natural surroundings. Elevate the soil around the pond slightly so that excess water will flow away from the pond, not into it. Make sure that any drainage from the pond is away from your house. Plan to landscape around the pond to provide habitat for frogs and birds that need land and water.... More »
