Probiotics are several classes of functional foods beneficial to the health and performance of animals. However, the viability of microorganisms with probiotic action may be impaired during passage through the host's gastrointestinal tract or by the form and length of food storage period. Therefore, microencapsulation appears as a promising technique in the protection of probiotics, promo…
Dr. H. Volkoff's program will include, but will not be limited to": (i) the execution of the research project "Characterization of appetite regulating factors in two characid fish, pacu (Piaractus mesopotamicus) and dourado (Salminus brasiliensis): cDNA cloning and effects of food quantity and quality on gene expression; (ii) serve as co-adviser of graduate students and collaboration with…
Soybean meal is an important protein source in aquafeeds, but it's also used in human diet which increases demand and price of this source. Detoxified Jatropha curcas kernel meal is a byproduct of biodiesel extraction that can be used as an alternative protein source for fishes feeds mainly because of its high protein composition, similar to the soybean meal. Some studies points out that …

Brazil is one of the top 15 countries in what regards aquaculture production. Additional expansion of activity requires studies focusing on the replacement of dietary animal protein sources, especially fish meal (FM), the main protein source in aquafeeds, by vegetable protein sources, more abundant, less expensive and sustainable. The inclusion of plant protein sources in aquaculture diet…
Aquaculture is the most successful zootechnical activity in Brazil during the last decade, leveraging the jobs supply, income generation and the feed industry. Food is responsible for approximately 60% of the total production costs and the reduction of its economic impact depends on the choice of the ingredients in order to optimize the production, aiming at the greater use of the nutrien…
Antibiotics and chemotherapeutics have been used in the treatment of bacterial infections associated with the intensification of aquaculture practices. However, these measures are not appropriate from the environmental and biosafety points of view, which stimulates the search for sustainable alternatives. In recent years, the use of nutritional strategies and immunonutrition have emerged …

Aquaculture has grown considerably worldwide in last decades, but it faces the challenging problem of overcoming the economic and environmental impacts of fish meal, the main protein source in fish feed. Plant based diets alternatives are being studied, but the lack of palatability of vegetable protein sources to fish represents an obstacle. Fish have a developed sensory system for olfact…

Vitamin A is a generic term for compounds with the qualitative biological properties of retinol. In nature, there are three active forms of vitamin A: alcohol (retinol), aldehyde (retinal) and acid (retinoic acid). Vitamin A is involved in many physiological processes for optimal function of an animal. Cell differentiation (vital for reproduction), function in vision, development of epit…
