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.

Pond Dynamics/Aquaculture Collaborative Research Data Reports: Volume Four, Number Two, Philippines Project -- Cycle II of The Global Experiment

Published: 
June 1, 1991
U.S. Agency for International Development
The Work Plan for Cycle II outlined experiments designed to test the hypothesis that organic maintenance fertilizer inputs would perform better, in terms of fish production and of water quality, than inorganic inputs with equivalent contents of total nitrogen and phosphorus. The CRSP freshwater...Read more

Spatio - Temporal Variations in Community Structure on a Heavily Fished Slope in Bolinao, Philippines

Published: 
August 1, 1989
U.S. Agency for International Development
An analysis of variations in community structure along a heavily fished fore reef slope in the Philippines indicates that depth and heterogeneity at the 1 and 10 cm scales were dominant structuring factors. Bottom temperature also appeared to be influential, but its effect was difficult to isolate...Read more

Improved Method for Fitting Gillnet Selectivity Curves to Predetermined Distributions

Published: 
June 1, 1988
U.S. Agency for International Development
Monte Carlo optimization with constraints was used to estimate parameters of "skew-normal" selectivity curves for gillnets. Non-linear functions of mesh size were explored in addition to the linear ones described by Wulff (1986). This methodology can be used to estimate the parameters for...Read more

User's Manual for Simulpop, a Program to Simulate Series of Length Frequency Distributions of An Exploited Fish Stock

Published: 
May 1, 1988
U.S. Agency for International Development
The objective of the program is to obtain a series of monthly length­ frequency distributions representing the catch of a population with known parameters (life history and fishing activity related parameters). Consequently, it is possible to verify the ability of different length frequency...Read more

Spawning Induction and Pond Culture of the Spotted scat (Scatophagus argus Linnaeus) in the Philippines: Final Report

Published: 
January 1, 1988
U.S. Agency for International Development
The primary objectives of our PSTC project were to determine the feasibility of culturing scat in brackishwater ponds, and to develop standardized techniques for its propagation. To achieve these objectives, we conducted experiments designed to 1) establish suitable pond growout strategies for scat...Read more
