Sustainable feed formulation to community‐based aquaculture: Oreochromis niloti...
Pires, Sílvia F. S.; Vital, Inês; Pereira, Vitória; Bustani, Henriques; Aragão, Cláudia; Engrola, Sofia; Cabano, Miguel; Dias, JorgeCommunity-based aquaculture can reduce dependence on natural resources, promote biodiversity conservation, and improve local economies and food security. However, this activity is highly dependent on local conditions regarding natural resources, such as the availability of produced organisms, adequate feeds, and environmental factors. As ectothermic organisms, fish are more susceptible to temperature fluctuatio...
Metabolic and nutritional responses of Nile tilapia juveniles to dietary methio...
Teodósio, Rita; Engrola, Sofia; Cabano, Miguel; Colen, R.; Masagounder, Karthik; Raquel Cêa de Aragão Teixeira, CláudiaCommercial diets for tilapia juveniles contain high levels of plant protein sources. Soybean meal has been utilised due to its high protein content; however, soy-based diets are limited in methionine (Met) and require its supplementation to fulfil fish requirements. DL-Methinone (DL-Met) and Ca bis-methionine hydroxyl analogue (MHA-Ca) are synthetic Met sources supplemented in aquafeeds, which may differ in bio...
Modulation of dietary protein to lipid ratios for gilthead seabream on-growing ...
Aragão, Cláudia; Cabano, Miguel; Colen, R.; Teodósio, Rita; Gisbert, Enric; Dias, Jorge; Engrola, SofiaGilthead seabream (Sparus aurata) tend to increase fat deposition during summer farming conditions in the Mediterranean, which may negatively affect productive performance and consumers' quality perception of the final product. Therefore, this study evaluated the impacts of protein to lipid ratios in low fishmeal/fish oil diets on growth performance, body composition, feed conversion and nutrient utilization of...
Alternative formulations for gilthead seabream diets: towards a more sustainabl...
Aragão, Cláudia; Cabano, Miguel; Colen, R.; Fuentes, Juan; Dias, JorgeTo 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 nutrie...
