“…Aride et al (2021) did not report biometric significant tambaqui growth after fed diets with until 30% inclusion of wild rice, Oryza spp. However, Vendruscolo et al (2009) included biologically treated apple pomace in the diet of tilapia fingerlings and observed an increase in biometric parameters in comparison with the Control group.…”

The demand for products to replace high-cost raw materials, such oil and fish meal, in the manufacture of feed for use in aquaculture, while also guaranteeing the nutritional quality of the diets, is increasing. Silage produced with fish and vegetables residues is a low-cost and efficient protein source. The objective of the present study was to evaluate the physiological and biochemical responses of tambaqui fingerlings fed four different levels of silage included in commercial feed with 28% crude protein, over two periods: 45 and 90 days. Each treatment was carried out over three replications, with 10 tambaqui in each 100 L experimental tank. At the end of each established period, blood samples were collected from five animals from each repetition to determine the hematological and biochemical variables. Body weight and total length, hepatosomatic and liposomal indices and hematocrit of specimens fed with diets supplemented with silage did not exhibit significant changes in both assessment period. After 45 days of feeding, the hemoglobin concentration increased when tambaqui were fed a diet including 20% silage. The red blood cell count, mean corpuscular volume and mean corpuscular hemoglobin did not change between treatments in either period. The total protein concentrations increased significantly in the plasma of tambaqui fed with diets with the inclusion of 5 and 10% of silage, evaluated after feeding for 45 days. It was found that the groups which had silage included in their diet did not exhibit significant alterations in the evaluated parameters, and the diet was therefore not consider harmful to the health of tambaqui. Therefore, the use of silage as a feed supplement during tambaqui farming is a sustainable alternative for producers, as it leads to a reduction of impacts of fish and vegetables waste disposal.

“…Commercial food products such as corn and sugar are not yet economically feasible for hydrogen production. Alternatively, agroindustrial residues and wastewaters with organic waste such as food processing and animal wastes have great potential as sources of substrate for biotechnological applications . Agroindustrial residues, wastewaters and other substrates, which are generally rich in carbohydrates, can provide essential nutrients required for biohydrogen production and reduce treatment and disposal costs.…”

SUMMARYHydrogen is a clean energy carrier with great potential to be an alternative fuel. Anaerobic hydrogen fermentation seems to be more favorable, since hydrogen is yielded at high rates and various organic waste and wastewater enriched with carbohydrates as substrate result in low cost for hydrogen production. Abundant biomass from various industries could be a source for biohydrogen production where combination of waste treatment and energy production would be an advantage. Carbohydrate-rich nitrogen-deficient solid wastes such as starch residues can be used for hydrogen production by using suitable bioprocess technologies. Alternatively, converting biomass into gaseous fuels, such as biohydrogen, is possibly the most efficient way to use these agroindustrial residues. This review summarizes the potential of starch agroindustrial residues as a substrate for biohydrogen production. Types of potential starch agroindustrial residues, recent developments and bio-processing conditions for biohydrogen production will be discussed.

“…Um triacilglicerol com tal composição garante um aproveitamento metabólico melhor deste nutriente, paralelamente a uma estabilidade oxidativa maior do óleo obtido (Akoh, 1995;Bell & Bradley, 1997;Stein, 1999), com vantagens nutricionais frente aos óleos de peixe submetidos a hidrogenação parcial (Chapman & Regenstein, 1997). A crescente produção de peixes tem proporcionado a procura por fontes protéicas alternativas, preferencialmente baratas, para a suplementação de dietas de peixe (Vendruscolo et al, 2009). O alto teor protéico encontrado em peixes faz com que o principal destino dos resíduos do beneficiamento seja para a produção de farinha de peixe, para alimentação animal, produto que apresenta cerca de 70% de proteína com a vantagem do baixo custo (Arruda et al, 2006;Seibel & Soares, 2003).…”

RESUMOO setor pesqueiro, em especial a pesca extrativa marinha, é uma atividade de grande importância econômica em diversas localidades do Brasil. A industrialização de peixe gera uma quantidade expressiva de resíduos ricos em proteínas e em ácidos graxos de cadeia longa, entre os quais se destacam os insaturados da série ômega-3. Este trabalho teve como objetivo fazer uma revisão sobre as alternativas tecnológicas disponíveis para aproveitamento de resíduos de peixe, como maneira de se agregar valor a este material, sob o enfoque da tecnologia limpa. Este material pode ser processado para a obtenção de óleo, farinha ou silagem que, por sua vez, podem ser aplicados na alimentação animal. O óleo obtido pode ainda ser estabilizado mediante reações de interesterificação, sendo que os triacilgliceróis estruturados assim obtidos podem ser aplicados em rações, com vantagens nutricionais sobre os óleos originais. Os resíduos de peixe podem ser aplicados como substrato para a produção de proteína texturizada, concentrado protéico, carne mecanicamente separada, surimi, produtos reestruturados ou até mesmo óleo, utilizados na alimentação humana. A conversão do óleo obtido a biodiesel é outra proposta de interesse particular no campo de combustíveis alternativos. Palavras-chave: pescado, subprodutos, tecnologias limpasAlternatives for adding value for the fish processing wastes ABSTRACTThe fish farming industry, especially the marine extractive fishery, is an activity of great economic importance in many parts of Brazil. Industrial fish processing operations generate a significant amount of wastes, which are rich in proteins and longchain fatty acids, among which the unsaturated omega-3 fatty acids are prominent. The aim of this study is to make a review about the technological alternatives available for the utilization of fish wastes, such as a way for adding value to this material, focusing on green technologies. This material can be processed to obtain oil, meal or silage, that may be applied in livestock feeding. The obtained oil can further be stabilized by means of interesterification reactions, considering that the structured triglycerides thus obtained can be used in animal feeding, with nutritional advantages over original oils. The fish wastes can be applied as a substrate for the production of texturized proteins, protein concentrate, mechanically deboned meat, surimi, reestructured products or even oil, used for human feeding. The conversion of the extracted oil into biodiesel is another proposal of particular interest in the field of alternative fuels.
