Análisis financiero de una producción piloto del rotífero, Brachionus  rotundiformis, con una dieta artificial
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Alvarez-Lajonchére, L.; Sánchez-Téllez, J. L.
Se realizó un estudio piloto de cultivo intensivo por  lotes en ciclos de cuatro días de rotíferos pequeños, Brachionus  rotundiformis Tschugunoff, 1921, para la alimentación de peces marinos, basado en el uso de Culture Selco Plus® como  alimento y oxígeno puro. Se aplicaron los mejores tratamientos de experimentos previos con oxígeno puro, flujo de agua  abierto, uso de fibra sintética para la colecta de materia orgánica y el empleo de bombas dosificadoras para el suministro  continuo del alimento. Con una densidad inicial de 252±21 rotíferos/ml se logró una densidad media de 1 595±53  rotíferos/ml a la cosecha, sin diferencias significativas entre las repeticiones (ANDEVA, P &gt; 0,05). Los parámetros ambientales  se mantuvieron estables e intervalos...

Bilan et perspectives de developpement des DCP au Cap-Vert

A new programme concerning the experimentation of about thirty Fish Aggregating Devices (FADs) is to start in the Cape Verde Islands at the end of 1999. In this context, this communication is intended: - to evaluate the halieutic, economic and social conditions of the artisanal fishery in this archipelago, notably in terms of assets and constraints. Although these conditions are very heterogeneous depending on islands, the fads seem to be able to help the stabilization and the development of the fishing activities, disadvantaged by a low productivity, limited operating ranges of boats, and very irregular outings at sea. But the narrowness of the domestic market is likely to cause drops in the fish prices if the production increases, while the absence of...

O objetivo deste trabalho foi calcular o custo de produção do milho de verão fertilizado com lodo de esgoto. O milho foi cultivado com preparo reduzido de solo em experimento instalado no ano agrícola 2001/2002 na Fazenda de Ensino e Pesquisa da Faculdade de Ciências Agrárias e Veterinárias/UNESP, Câmpus de Jaboticabal, em área de 1/16 de hectare e solo LVef. Aplicou-se 10 t ha-1 de lodo de esgoto obtido por tratamento com polímero. A matriz econômica foi montada de acordo com o modelo de custos de produção adotado pelo Instituto de Economia Agrícola da Secretaria de Agricultura e Abastecimento do Estado de São Paulo. Para os cálculos, utilizaram-se os preços vigentes no mercado no ano agrícola correspondente. Com o emprego do Excel foram obtidos os custos...

Economic Analysis of a Traveling Gun for Feedyard Dust Suppression
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Amosson,   Stephen H.; Bretz,   Fran E.; New,   Leon L.; Almas,   Lal K.
Dust created in feedyards can adversely affect cattle performance.  Dust suppression can be accomplished by moistening pen surfaces with traveling gun(s) sprinklers, solid-set sprinklers, and water trucks.  This study specifically addresses the fixed and operational costs associated with a traveling gun sprinkler system for various sized feedyards.
