“…To the best of our knowledge, there are no available studies reporting the mixture of so many plant by‐products in fish diets. Studies testing increasing levels of single by‐products in gilthead seabream diets have shown that, for instance, carob seed germ meal can be included at a maximum level of 340 g/kg (Martínez‐Llorens, Baeza‐Ariño, Nogales‐Mérida, Jover‐Cerdá, & Tomás‐Vidal, ) and corn DDGS can be included at 350 g/kg (Diógenes et al, ) without negative effects on growth or protein and energy retentions. The current study showed that fish fed the PLANT diet performed better than those fed the CTRL diet, which included relatively high levels of fishmeal.…”

“…The CTRL diet used in this study had a similar formulation to a commercial diet used nowadays in gilthead seabream production, which already includes a large amount of plant ingredients as protein sources. However, the concept beyond the scope of this study was to minimize the use of ingredients that may be used directly for human consumption and focuses more on non-conventional feed ingredients, from both animal and plant ori- (Diógenes et al, 2019) without negative effects on growth or protein and energy retentions. The current study showed that fish fed the PLANT diet performed better than those fed the CTRL diet, which included relatively high levels of fishmeal.…”

To support the expected increase in aquaculture production during the next years, a wider range of alternative ingredients to fishmeal is needed, towards contributing to an increase in production sustainability. This study aimed to test diets formulated with non‐conventional feed ingredients on gilthead seabream (Sparus aurata) growth performance, feed utilization, apparent digestibility of nutrients and nutrient outputs to the environment. Four isonitrogenous and isoenergetic diets were formulated: a control diet (CTRL) similar to a commercial feed and three experimental diets containing, as main protein sources, plant by‐products, glutens and concentrates (PLANT); processed animal proteins (PAP); or micro/macroalgae, insect meals and yeast (EMERG). Diets were tested in triplicate during 80 days. The EMERG treatment resulted in lower fish growth performance, higher FCR and lower nutrient and energy retentions than the other treatments. The lowest protein digestibility was found for the EMERG diet, which caused increased nitrogen losses. The PLANT and PAP treatments resulted in better fish growth performance, higher nutrient and energy retentions, and lower FCR than the CTRL treatment. The significant improvement in FCR found for fish fed PLANT and PAP diets and the high protein digestibility of these diets contribute towards minimizing the environmental impacts of seabream production.

“…Even with higher intake, these diets presented lower cost per unit of biomass produced when compared to the others, probably due to the utilization of meat and bone meal, which is a lower cost ingredient. Other studies have shown that the costs of fish production can be reduced by replacing, to the maximum extent possible, the use of high value protein sources such as fishmeal, with alternative energy sources and low-cost protein (Cerdeira et al, 2018;Davies et al, 2019;Diógenes et al, 2019). The inclusion of protein and energy levels above the T-37 diet contributed to the gradual increase in feeding cost without providing a significant increase in biomass, which is undesirable in both productive and environmental aspects (El Sayed et al, 2015;Salze and Davis, 2015).…”

“…Information related to performance and physiological condition in the final stages of grow-out are insufficient, especially in reference to the larger fish (>4 kg). Supplying ideal concentrations of nutrients and energy in the creation could considerably reduce environmental impact and production costs, besides increasing the quality of the fish (Rawles et al, 2018;Diógenes et al, 2019).…”

The present study evaluated practical diets with increasing levels of protein and energy on performance, fillet composition, feed cost, and physiological responses of pirarucu (Arapaima gigas) juveniles during the grow-out phase in a net cage system. In an on-farm trial for 90 days 225 pirarucu juveniles with initial weight ± standard deviation of 2025 ± 335 g were fed to apparent satiety with extruded diets containing 37.4 (T-37), 40.8 (T-40), 43.9 (T-43), 45.5 (T-46), and 47.1% (T-49) crude protein (CP), increasing lipid levels, and energy:protein ratio fixed in 10 kcal g-1. Protein and lipid concentrations in the diets influenced the cost, fillet composition, and important physiological aspects of the health maintenance and productive performance of the pirarucu juveniles. Fish fed the T-37 diet had lower concentrations of fat in body cavity, fillet and blood, and had a lower cost associated with feeding. The increase in protein and energy levels in the other diets tested reduced the economic return, did not improve the zootechnical performance and caused physiological changes in the fish.

“…Quanto aos desperdícios de grãos do pós-colheita, 18,3% ocorrem durante o processo de secagem e armazenagem decorrentes da contaminação, avaria e impureza dos grãos (Reykdal, 2018). A secagem dos grãos é realizada por meio de um processo de redução da umidade do grão, conferindo importância à armazenagem, conservação e estabilização físico-química (Babalis & Belessiotis, 2004;Diógenes et al, 2019), podendo ser conduzida por métodos tradicionais ou pelo uso de caldeira através da queima de resíduos destes grãos. O uso de métodos tradicionais para secagem de grãos resulta em maior contaminação com altos índices de avaria e impurezas (Cruz et al, 2017;Ingvordsen et al, 2018).…”

A teoria do valor capturado postula que o lucro potencial na entrega de uma oferta de produtos e serviços é avaliado por meio da relação preço e desempenho, características do produto e do serviço e das competências da empresa. Este estudo trata da captura do valor em ofertas Sustainable Product-Service System (S-PSS). O objetivo deste estudo é desenvolver um instrumento de coleta de dados para capturar valor de ofertas S-PSS para a secagem e armazenagem de grãos desenvolvido para agricultores. O instrumento foi concebido visando o emprego de análises de cenários por meio de técnica de modelagem de dados de preferência como Conjoint Analysis (Choice-based Conjoint e Menu-based Choice), associadas e modelos econométricos com abordagem (Willingness-to-pay) para mensurar o quanto o consumidor está disposto a pagar por determinada oferta. O instrumento foi planejado para associar as respostas à dados socioeconômicos e de propensão à sustentabilidade do agricultor. Os cenários dos produtos foram planejados para ofertas da secagem e armazenagem de grãos, serviços de gestão de dados, opção de compra ou aluguel e a disposição a pagar do agricultor pela aquisição e demais serviços adicionais. Este artigo apresenta a validação por conteúdo do instrumento.
