Zooplankton nutrition study under conditions close to natural with the use of radioactive phosphorus ArchiMer
Pavlovskaya, T; Zesenko, A.
Lack of a sensitive method for in situ study of the nutrition quantitative characteristics (and food balance in particular) for zooplankton populations in low-productivity regions was the reason for developing one. For the basis of such a method the authors selected the property of radioactive phosphorus isotopes of fast and effective embedding into all plankton components. The method described above allowed not only to quantitatively determine the consumption and transportation of a substance by individual species and populations of zooplankton; it opens new horizons for investigation of the zooplanktonic association role in regeneration of mineral phosphorus.

The Pilot Food Price Subsidy Scheme in the Philippines: Its Impact on Income, Food Consumption, and Nutritional Status AgEcon
Garcia, Marito; Pinstrup-Andersen, Per.
This report presents the results of a pilot targeted food price subsidy scheme implemented in three provinces of the Philippines for 12 months beginning in mid-1983. It assesses the economic and nutritional effects of the scheme, analyzes its technical and administrative feasibility, and considers possible alternatives. The scheme consisted of price discounts on rice and cooking oil and a nutrition education component.

Approche de la capacité trophique d'un écosystème conchylicole ArchiMer
Heral, Maurice; Deslous-paoli, Jean-marc; Prou, Jean.
After a short bibliographical study of the different approaches for determination of the trophic capacity of a bay for molluscs culture, the authors, with a global mode, show the relations between the growth performance of the oysters Crassostrea gigas in relation with the cultivated stocks. The volumes of consumed and assimilated food are calculated for the stocks in relation with the incoming volumes of water in the bay and the residence time for neap tide and spring tide. The authors find a decrease of growth rate in relation with the volume of consumed food. When it is above 60% and when the volume of assimilated food is above 20%, there is a large decrease of the growth of oysters.

Palatability enhancing nutrients for the European eel, <i>Anguilla anguilla</i> L. OMA
Pacolet, W.; Reynders, K.; Ollevier, F.P..
Feeding experiments with European glass eels <i>Anguilla anguilla</i> L. demonstrated a high degree of attractiveness for the natural diets Tubifix and cod roe. Previous experiments had indicated that incorporation of bovine spleen and/or blood into paste feeds significantly improved the growth rate and survival. To increase feed consumption, the effect of some basic components available from the current generation of chemo-attractants were evaluated. Using a modified Omission Test Procedure, we focused on monosodiumglutamate, betaine, the nucleotides IMP and GMP, and fractions of cattle blood. These components were incorporated into non-attractive casein-based test diets and administered following standardized procedures to intensively...

Ecología trófica de la merluza común (Merluccius hubbsi) del Mar Argentino. Parte 3. Consumo anual de alimento a nivel poblacional y su relación con la explotación de las pesquerías multiespecíficas. OceanDocs
Prenski, L.B.; Angelescu, V..
The English contents gives a general view on the topics treated in this contribution developed mainly on the basis of a quantitative and ecological analysis of trophic relationships in the Argentinian Continental Shelf, in which common hake and its food species are involved (anchovy, mictophids, small fishes, squids and macrozooplankton crustaceans). The most original part consist in the application of bioenergetic and simulation models for estimating the annual food consumption by individuals and by stocks of common hake during 1970-1987, considering at the same time, the effects of commercial catches on the stockbiomasses in predator-prey relationships. From this point of view three trophic-fishery relationships are evident, namely: "Common...

Adoption of Hybrid maize in Zambia: effects on gender roles, food consumption, and nutrition AgEcon
Kumar, Shubh K..
Enhanced agriculture productivity in sub-Saharan Africa is critical to promote economic growth and poverty alleviation and to avoid increasing food scarcities in the region. The impact of commercialization and intensification of agriculture on the well- being of the rural poor depends on how they are carried out. Past research by IFPRI and collaborating institutions on commercialization of small- scale farming in about a dozen countries provided new knowledge about the relationships between commercialization and rural well- being as measured by incomes, consumption, and nutrition. These links were shown to depend greatly on household behavior, which in turn is influenced by intrahousehold processes. A better understanding of these processes is likely to...

A Dietary Assessment of the U.S. Food Supply: Comparing Per Capita Food Consumption with Food Guide Pyramid Serving Recommendations AgEcon
Kantor, Linda Scott.
Most American diets do not meet Federal Food Guide Pyramid dietary recommendations. On average, people consume too many servings of added fats and sugars and too few servings of fruits, vegetables, dairy products, lean meats, and foods made from whole grains compared with a reference set of Food Guide Pyramid serving recommendations appropriate to the age and gender composition of the U.S. population. In addition, while the healthfulness of diets has improved over time, the pace of improvement has been uneven. For example, while Americans consumed record amounts of fruits and vegetables in 1996, consumption of caloric sweeteners also reached a 27-year high. This report is the first dietary assessment to use ERSís time-series food supply data to compare...

America's Eating Habits: Changes and Consequences AgEcon
Individual chapters in this book provide different perspectives on the nutrition problems in the United States: what are the economic costs associated with unhealthy eating patterns; how do dietary patterns compare with dietary recommendations; how do national income and prices, advertising, health claims, and trends in eating away from home affect nutrient intake; how much do people know about nutrition and how does nutrition knowledge and attitudes affect intake of fats and cholesterol; how do different government programs and regulations influence food expenditures and consumption; what are some public and private efforts to improve healthy eating; and what are potential impacts of healthier eating on domestic agriculture.

The Changing Food Assistance Landscape: The Food Stamp Program in a Post-Welfare Reform Environment AgEcon
Gundersen, Craig; LeBlanc, Michael; Kuhn, Betsey A..
The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) dramatically transformed and continues to transform the food assistance landscape in the United States. The Act cut more funds from the Food Stamp Program than it did from any other program, through reductions in benefits per person and restrictions in eligibility. Despite these cuts, food stamps now have a more prominent role in the post-welfare reform social safety net because the largest cash-assistance entitlement program, Aid to Families with Dependent Children (AFDC), was replaced with the Temporary Assistance to Needy Families (TANF) program, a nonentitlement program. This leaves the Food Stamp Program as one of the only remaining entitlement programs available to...

Moving Toward the Food Guide Pyramid: Implications for U.S. Agriculture AgEcon
Young, C. Edwin; Kantor, Linda Scott.
Recent studies show that average diets differ considerably from Food Guide Pyramid recommendations. The gap between current consumption and recommendations is particularly large for caloric sweeteners, fats and oils, fruits, and certain vegetables, notably dark-green leafy and deep-yellow vegetables, and dry beans, peas, and lentils. The change in food consumption needed to meet Food Guide Pyramid serving recommendations will result in adjustments in U.S. agricultural production, trade, nonfood uses, and prices. The net adjustment in crop acreage is projected to be relatively small, about 2 percent of total cropland in 1991-95. However, this small net adjustment masks larger anticipated changes for some sectors, particularly sweeteners, fats and oils, and...
