Aquaculture en système clos : estimation des coûts de production pour l'élevage du bar et du turbot
Provedor de dados: 5
Autores: Lavenant, M; Paquotte, Philippe.
Two major constraints to aquaculture have raised in most countries : the little availability of convenient sites because of the competition for the use of the coastline and the progressive implementation of regulations to reduce the impact of the farms on the environment. The technique of recirculation, widely used for hatcheries, has been developed to answer these constraints and to get free of the natural variations in order to regulate the résults. The ongrowing experimental facilities have proved good enough results to make it possible to conceive industrial projects for sea-bass and turbot. In first approach, the production costs of these systems are similar to traditional techniques but expected productivity gains due to an increase of zootechnical...

A review on applications of greenhouse drying and its performance
Provedor de dados: 111
Autores: Sahdev, Ravinder Kumar; Kumar, Mahesh; Dhingra, Ashwani Kumar.
Limited sources and rising cost of fossil fuels has instigated researchers to look towards renewable energy resources.  Among renewable energy resources, solar energy is required to become indispensable in the future, as it is inexpensive, abundant, inexhaustible, environmental friendly and non-pollutant.  Most of the people living in developing countries are dependent on agriculture.  Agricultural products are dried to increase the storage life, minimize the packaging requirement and reduce the transportation weight.  Solar drying for drying agricultural products is being practiced since long back throughout the world.  Because of its drawbacks, advance technique, i.e. greenhouse drying, is being adopted for drying crops to reduce the drying time and...
