Poultry by-product meal as dietary protein source for dourado, Salminus brasiliensis: an economic appraisal
Provedor de dados: 63
Autores: Donadelli,Renan Antunes; Aguilar,Fredy Armando Aguilar; Sonoda,Daniel Yokoyama; Cyrino,José Eurico Possebon.
ABSTRACT: The dourado, Salminus brasiliensis, a large, carnivorous, Neotropical, Characin, is highly regarded for fish farming and sport fishing alike. However, studies on the farming and husbandry of dourado are still scarce. This study evaluated the performance of dourado fed diets formulated so as to contain increasing levels of poultry by-product meal as a replacement for fish meal and aimed to identify the maximum level of replacement to maximize profit. The trial was set up in a closed recirculation system with controlled water quality (temperature 27 °C, dissolved oxygen 6.5 mg L−1, pH 7.4, and ammonia 0.25 mg L−1). Juvenile fish were stocked in tanks in a completely randomized design, acclimatized to system conditions and experimental diets, and...

Demand for fisheries products in Brazil
Provedor de dados: 63
Autores: Sonoda,Daniel Yokoyama; Campos,Silvia Kanadani; Cyrino,José Eurico Possebon; Shirota,Ricardo.
Fish consumption per capita in Brazil is relatively modest when compared to other animal proteins. This study analyses the influence of protein prices, other food prices and population income on the fish demand in Brazil. First, the problem of fish supply in Brazil is characterized. It is followed by reviews of the relevant economic theory and methods of Almost Ideal Demand System - AIDS and their elasticity calculations. A descriptive analysis of fish demand in Brazil using the microdata called "Pesquisa de Orçamento Familiar" (Familiar Budget Research) - POF 2002-2003 is presented. Finally, demand functions and their elasticities are calculated for two different cases: one considering five groups of animal proteins (Chicken; Milk and Eggs; Fish;...

Fish and fishery products trade in Brazil, 2005 to 2015: A review of available data and trends
Provedor de dados: 63
Autores: Barone,Rafael Simões Coelho; Lorenz,Evandro Kleber; Sonoda,Daniel Yokoyama; Cyrino,José Eurico Possebon.
ABSTRACT: Along the last ten years fish and fishery product trade in Brazil has been on a downward trajectory turning a profit of US$ 98.6 million in 2005 into a loss of US$ 1.25 billion by 2014. On the other hand, the country is a leading producer of grains and has the third largest animal feed industry in the world, which has added 5.5 million hectares of freshwater reservoirs and 3.5 million km2 of an exclusive marine economic zone in the same period, a sizable potential for development of the aquaculture industry. This study aims at unveiling strategies for the reduction of the deficit in the Brazilian seafood trade balance, based on critical analysis of the quantitative and qualitative characteristics of imported fishery products. The fish and fishery...

Digestibility and pricing of Chlorella sorokiniana meal for use in tilapia feeds
Provedor de dados: 63
Autores: Barone,Rafael Simões Coelho; Sonoda,Daniel Yokoyama; Lorenz,Evandro Kleber; Cyrino,José Eurico Possebon.
ABSTRACT: Several microalgae contain in excess of 50 % crude protein with amino acid profile comparable to that of fish meal. In addition, high polyunsaturated fatty acid contents encourage their use in animal feeding and nutrition, particularly in the formulation and processing of aquafeeds. This study aims at estimating the feasibility of Chlorella meal as feed ingredient for the feeding and nutrition of farmed tilapia based upon digestibility data. Juvenile tilapia were stocked in conical-bottomed tanks (200 L) with superficial, continuous water flow, and fed to apparent satiation in three daily meals with a reference diet and a test diet containing 30 % lyophilized Chlorella sorokiniana added of an inert marker. Feces were collected overnight by...
