This research is commissioned by the professorship Novel Proteins: Insects and Fish, Healthy, Sustainable and Safe (INVIS) and conducted with the aim to investigate the constraints that hinder the uptake of insect-based feed in the Dutch finfish aquaculture branch and advise upon how to initiate a transition within the branch to adopt insect meal in fish feed widely. This is a underlying report of the webinar Insect culture in the Netherlands for feed and food on January 19, 2021.

Stefan Bengtsson's commentary about policy hegemony discusses the alternative discourses of socialism, nationalism, and globalism. However, Stefan does not adequately demonstrate how these discourses can overcome the Dominant Western Worldview (DWW), which is imbued with anthropocentrism. It will be argued here that most policy choices promoting sustainability, and education for it, are made within a predetermined system in which the already limiting notion of environmental protection is highly contingent on human welfare. What would really contest the dominant assumptions of Vietnamese policy and, more specifically, education for sustainable development (ESD) is an alternative discourse that challenges the DWW. That alternative discourse embraces philosophical ecocentrism and practices of ecological justice between all species, and deep ecology theory - all perspectives fundamentally committed to environmental protection. https://doi.org/10.1080/00958964.2015.1048502 LinkedIn: https://www.linkedin.com/in/helenkopnina/

This paper conceptualises tourist idleness as a temporary engagement in slow, slothful and entirely unstructured holiday activities. We aim to extend the studies that prioritise the modalities of holidays in nature that encourage simplified, slower, immersive experiences, and which celebrate mindfulness, slowness and stillness as part of a tourist journey. In framing idleness as a relaxing, creative and recuperative holiday practice, we suggest that creating places of otium which encourage ‘doing nothing’ can in many ways enhance tourist wellbeing. To this end, we discuss the significance of spatial, temporal and existential elements of tourist idleness, whilst arguing that this ‘practice’ should be more celebrated in our modern, high-speed societies.

The European eel (Anguilla anguilla) is a delicacy fish and an integral part of the Dutch culinary history. However, the stock of adult eel has decreased significantly due to a precipitous recruitment of glass eel fall. This relates to multiple factors including obstacles in migration pathways, loss of habitat and chemical pollution. Consequently, Anguilla anguilla has become a critically endangered species and is protected under European legislation. One possible solution, explored on laboratory scale, is the captive reproduction of eels and growth of glass eel in aquaculture. A big challenge of this technique is the limiting aspect of possible nutrients for the eels in the larval stage, as the diet must be delivered in micrometric capsules (< 20 µm) with a high protein content. Such diets are not yet available on the market. Electrohydrodynamic atomization (EHDA) is a novel option to prepare a micro-diet suitable for eel larvae. EHDA is especially interesting for its narrow size distribution capabilities and for applications which require submicrometric sizes. This project aims to evaluate the use of EHDA to produce high protein content micrometric size capsules for feeding larval eels. If successful, this would assist in the captivity production of glass eel and to make the eel culture independent of wild catches, restoring the culinary market. The project will be conducted in two phases. Firstly, tests will be conducted to evaluate the necessary conditions of the capsules using EHDA. Subsequently, the obtained capsules will be tested as feed for eel larvae. The main objective is to favour the development of a more sustainable eel culture, regarding the possibilities of investigating the current fish in natura option and exchanging it for a captivity one.
