Productivity and Efficiency
According to the U.S. Environmental Protection Agency, water efficiency is the smart use of our water resources through water-saving technologies and simple steps. Using water efficiently will help ensure reliable water supplies today and for future generations. Topics addressed in this theme provide insights, lessons, and guidance on how diverse stakeholders are working to improve water management and reduce water use.

Thailand, East Asia and PacificFinal Report Covering Period 1988-1993: Contribution of Mangrove Detritus to The Production of Commercially Important Shrimp Species
Published:
January 1, 1991U.S. Agency for International Development
The overall hypothesis we tested was that juveniles prawns living within mangrove creeks derive significantly greater nutritional benefits from mangrove detritus than do juveniles and adults living offshore. We used a multiple isotope approach (carbon, nitrogen, and sulfur) to elucidate the degree...Read more

Nile tilapia (Oreochromisniloticus)are commonly grown in ponds fertilized to increase primary and secondary production. The fertilization fishponds has been widely studied, often with conflicting results. Temperate ponds, with low stocking densities, seem to require only phosphorus additions(Yamada...Read more
