    O objetivo deste trabalho foi avaliar o desempenho zoot√©cnico do camar√£o-daMal√°sia, Macrobrachium rosenbergii criados em sistema de biofloco e submetidos √†restri√ß√£o alimentar. Foram utilizadas 400 p√≥s-larvas do camar√£o distribu√≠das em doistratamentos; camar√Ķes alimentados sete dias na semana (controle) e camar√Ķesalimentados com restri√ß√£o nos finais de semana (s√°bado e domingo n√£o foi ofertadadieta). Tanto os par√Ęmetros zoot√©cnicos como os par√Ęmetros de qualidade de √°guan√£o apresentaram diferen√ßas significativas entre os tratamentos controle e restri√ß√£oalimentar. Portanto, o manejo de restri√ß√£o pode ser utilizado como alternativa pararedu√ß√£o de custos com alimenta√ß√£o artificial e m√£o-de-obra

    O presente estudo avaliou os par√Ęmetros zoot√©cnicos de til√°pias, O. niloticus criadas em sistema aquap√īnico e convencional. No sistema aquap√īnico foi utilizado um tan-que (900 L √ļteis) com 60 til√°pias, peso m√©dio (49,21 ¬Ī 4,76 g). O sistema convencional foi constitu√≠do por um tanque-rede (714 L √ļteis) com 49 til√°pias, peso m√©dio (47,76 ¬Ī 4,57 g). O manejo alimentar foi realizado duas vezes ao dia. A qualidade de √°gua ficou dentro do recomendado para a esp√©cie. O desempenho zoot√©cnico das til√°pias foi semelhante em ambos os sistemas, mostrando que a aquaponia pode ser utilizada sem preju√≠zos econ√īmicos

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low‚Äďmiddle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‚Äėsingle-use‚Äô consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low‚Äďmiddle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high‚Äď and low‚Äďmiddle‚Äďincome countries
