1. Multivariate study of Nile tilapia byproducts enriched with omega-3 and dried with different methods
Abstract The present work aimed at studying the effect of different drying methods applied to tilapia byproducts (heads, viscera and carcasses) fed with flaxseed, verifying the contents of omega-3 fatty acids. Two diets were given to the tilapia: a control and a flaxseed formulation, over the course of 60 days. After this period, they were slaughtered and th

2. Espectrometria de Emissão Atômica em Filamento de Tungstênio (WCAES) : potencialidades e aplicações / Tungsten coil atomic emission spectrometry: potentialities and applications
This thesis describes the analytical application of WCAES for the determination of Ca, Al, Cs, Sr and Cr in samples with different compositions. In all studies the observation zone of the detector related to the coil was critically evaluated. In the first study, Ca was determined in mineral water, coconut water and juice samples. It was necessary the dilutio

3. Extração e caracterização de óleos de resíduos de peixes de água doce / Extraction and characterization of freshwater fish waste oils
This study aimed to: (1) evaluate the performance and physicochemical characteristics of viscera oils from rainbow trout (Oncorhynchus mykiss), pacu (Piaractus mesopotamicus) and curimbatá (Prochilodus spp.) extracted by slow freezing, as a mechanism to release the lipids of the crude material, and (2) compare the stages of chemical refining (degumming, neu

4. Modeling of drying and adsorption isotherms of the fish feed
The aim of this work was to study the drying curves and equilibrium isotherms of extruded fish feed. The drying curves were determined at air temperatures of 50, 60, 70 and 80°C and airflow velocities of 1.5, 2.5 and 3.5 m/s). The equilibrium isotherms of relative humidity of air were obtained between 10 and 80% at 30, 40, 50, and 70°C. The experimental da

5. Desenvolvimento de Método Rápido de Análise de Histamina por Cromatografia Líquida de Alta Eficiência em Atum. / Development of Quick Method for Analysis of Histamine in Tuna by High Performance Liquid Chromatography.
Histamine is an important biogenic amine found in fish like tuna, mackerel, bonito and sardines, and in fermented foods like cheese, salami and sauerkraut. Its presence in food should not exceed certain limits, because the intake of this substance in quantities that vary from person to person, can cause scombroid poisoning, whose main symptoms are: abdominal

6. QUALIDADE DO PIRARUCU (Arapaima gigas, Schinz 1822) PROCEDENTE DE PISCICULTURA, ESTOCADO EM GELO, CONGELADO E DE SEUS PRODUTOS DERIVADOS
Investigated alterations in the cultivated pirarucu, the changes sensory, physical, chemical and microbiological aimed at determining the time of conservation in ice and frozen (-18 oC) of whole fish and filet. Also evaluated was the technological potential of this species, in the form of filet hot smoked, dry-salted, "panceta" and "carpaccio". In all sixtee

7. Osmotic dehydration, drying and liquid smoking in fillets of Nile tilapia (Oreochromis niloticus), Thai strain. / Desidratação osmotica, secagem e defumação liquida de files de tilapia do nilo (Oreochromis niloticus), variedade Tailandesa.
Foi estudada a influência de dois tratamentos na secagem convectiva de filé de Tilápia do Nilo (Oreochromis niloticus), variedade Tailandesa. No primeiro tratamento foi realizado o estudo do processo de desidratação osmótica utilizando solução binária (água + NaCl) e ternária (água + NaCl + sacarose). Foram verificadas as influências dos fatores

8. Usage and Environment Perception of Wetlands by a River Population in the River Basin of the Taquari-Antas Region, Rio Grande do Sul / O uso e a percepção ambiental de áreas úmidas por uma população ribeirinha na região da Bacia Hidrográfica do Rio Taquari-Antas, Rio Grande do Sul
Wetlands are important ecosystems for biodiversity protection; they show a great wealth of species and high levels of endemism. These environments are sources of natural resources for human populations, and they are among the most productive ecosystems in the world. Impacts on wetlands include both some habitat changes and destruction. Mankind depends on the

9. Study of the process of osmótica dehydration and drying of filés of it will mapará (Hypophthalmus edentatus). / Estudo do processo de desidratação osmotica e secagem de files de mapara (Hypophthalmus edentatus).
It was studied the influence of the osmotic dehydration process using binary (water + NaCl) and ternary (water + NaCl + sucrose and water + NaCl + corn syrup) solutions in the convective drying of mapará catfish (Hypophthalmus edentatus). The influence of temperature, salt concentration, sugar concentration, immersion time on the responses of weight los

10. Produção e caracterização de microparticulas obtidas por spray drying e coacervação complexa e seu uso para alimentação de larvas de peixes. / Production and characterization of microparticles by spray drying and complex coacervation and its use for feeding of larvae fish.
A microencapsulação é uma técnica para recobrimento de substâncias para a proteção e/ou liberação controlada das mesmas. As microcápsulas podem ser uma alternativa para obtenção de uma dieta para alimentação das larvas de peixe na piscicultura intensiva. Dois métodos de microencapsulação foram empregados para produção de micropartículas,

11. Preparo e caracterização de microcapsulas obtidas por polimerização ionica para alimentação de larvas de peixe / Preparation and characterization of microcapsules obtained by polymerization Ionica feeding of fish larvae
This research aimed at producing microcapsules capable of retaining proteins, with the objective of substituting the live organisms used in larval fish feed. Four different polysaccharides: alginate, carrageenan, gelan gum and pectin were used, all having the capacity to form gels by ionic polymerization both individually and in association, in order to prod

12. Secagem e defumação liquida de file de peixe matrinchã (Brycon cephalus)
The matrinchã (Brycon cephalus) is specie of fresh water fish from the Amazon basin, that also can be found in the San Francisco and Paraguay rivers. It is also known as piraputanga and matrinchão. Now this fish is diffusing in aquiculture, for sporting fishing practice, getting a considerable attaché value. Its meat is considered of first, possessing a p
