Overfishing Threatens Critical Link in the Food Chain
The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten ...

Accumulation of dietary methylmercury and effects on growth and survival in two estuarine forage fish: Cyprinodon variegatus and Menidia beryllina
Dietary methylmercury (MeHg) uptake by fish in relation to life stage, species, and level of exposure is poorly understood in lower trophic levels, particularly in estuarine species. The authors compared accumulation of dietary MeHg as well as sensitivity (survival and growth) to dietary MeHg exposure in two species of estuarine forage fish, Cyprinodon variegatus and Menidia beryllina. Fish ...

Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production
The world produced 2,241 million tons of grain in 2012, down 75 million tons or 3 percent from the 2011 record harvest. The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia. Each of these countries also is an important exporter. Global grain ...

China’s Rising Soybean Consumption Reshaping Western Agriculture
Global demand for soybeans has soared in recent decades, with China leading the race. Nearly 60 percent of all soybeans entering international trade today go to China, making it far and away the world’s largest importer. The soybean was domesticated some 3,000 years ago by farmers in eastern China. But it wasn’t until well after World War II that the crop gained agricultural ...

Karakul sheep production in Kazakhstan: an efficient collective enterprise under the state farm (sovkhoz) system and its collapse with the break–up of the Soviet Union
Prior to the demise of the Soviet Union in 1991, Karakul sheep in Kazakhstan were raised mainly on large collective state farms, sovkhozes. Farmers had to meet quotas on lamb and pelt numbers and received wages, while state farms provided veterinary and breeding services, animal feed and marketing. With the break–up of the Soviet Union, land ownership, farm facilities, animals and payment ...

ANFIS approach to the working of a compost–heat extractor
Composting is an organic sludge management option in which volatile solids are converted to carbon dioxide and water. As the sugar cane press mud undergoes aerobic composting, the bed heats–up to a temperature in the range of 50–70°C, releasing thermal energy and the heat liberated was extracted using a heat pipe. A neural network approach is applied to analyse the data obtained ...
