Fish nutrition can be the deciding factor between a robust and healthy farmed fish population and low aquaculture production. In an age where chemicals and antibiotics are under greater scrutiny than ever, a strong understanding of the role of nutrients and feed additives is essential in the aquaculture industry. Dietary Nutrients, Additives and Fish Health is a comprehensive review of dietary nutrients, antinutritional factors and toxins, and non-nutrient dietary additives, and their effects on fish performance and immune system function, as well as overall health. The book opens with an overview of fish immune systems and health. Subsequent chapters delve into proteins and amino acids, lipids and fatty acids, carbohydrates, beta glucans, vitamins, minerals, antinutrients, mycotoxins, nucleotides, prebiotics, probiotics, organic acids and their salts, and plant extracts and their impacts on fish health, growth, and development. The text then concludes with a chapter on feeding practices. Authored by leaders in aquaculture, Dietary Nutrients, Additives and Fish Health will be an invaluable resource to graduate students, researchers and professionals alike.

The theme of 2016 is ”Solidarity in a competing world - fair use of resources”. While on the one hand, one part of the world is profiting from natural resources, the other part of the world is suffering with hunger, malnutrition, human diseases, low income, violence and lately is also challenged through climate change. There is need to rethink and engage in a fair share of all resources between the continents and nations. This includes huge engagement into the management of natural resources to solve the long list of environmental threats expressed through ongoing erosion, loss of soil fertility and loss of biodiversity, and topped by climate change having strong impact on the productivity in agriculture, fishery and forestry, and the use and quality of water and of energy in the South.
Tropentag is the largest interdisciplinary conference in Europe focusing on development- oriented research in the fields of tropical and subtropical agriculture, food security, natural resource management and rural development. It is clear that a just and sustainable transformation of our food systems is urgently needed: climate change, conflicts, rising food and fuel prices, and growing social and income inequalities are exacerbating the vulnerabilities of our food systems. The theme invites diverse contributions that explore different pathways for transforming food systems and the trade-offs and synergies involved, ranging from more technical solutions, such as climate-smart agriculture and biofortified crops, to more systematic solutions for changing the underlying relationships of our food systems, such as agroecology and alternative food networks.
Tropentag is the largest interdisciplinary conference in Europe on development oriented research in the fields of sub-/tropical agriculture, food security, natural resource management and rural development. Taking place annually, Tropentag 2020 turned out to be a special challenge. Originally planned to take place in Prague, the Corona pandemic did not allow presence in or travel to Prague for prospective participants. ATSAF took on the challenge to organise a virtual Tropentag based on Zoom meetings being streamed on YouTube channels using the Whova as online conference platform from September 7 to 9, 2020.
Tropentag is the largest interdisciplinary conference in Europe, focused on developmentoriented research in the fields of tropical and subtropical agriculture, food security, natural resource management and rural development. Tropentag takes place annually, even though the past two years were particularly challenging, while the conference had to be organised as an online only event. One of the lessons that we learnt from the virtual conferences is that yes, it is possible to organise it that way, but that it is much better to meet and talk in person. We are thus very happy that this year (two years after what was initially planned), we are able to organise the Tropentag 2022 conference at the campus of the Czech University of Life Sciences Prague, Czech Republic, and thrilled that we will again meet all face-to-face, during the 14-16 September venue. However, some of you, due to various reasons, who could not come to Prague, you can still participate at this year Tropentag, as all plenary and oral scientific sessions are streamed via the Whova platform, and we also organise several online poster sessions.
Tropentag is the largest interdisciplinary conference in Europe on developmentoriented research in the fields of tropical and subtropical agriculture, food security, natural resource management and rural development. Normally, the Tropentag takes place annually. However, for reasons that by now have become obvious, the past two years have been particularly challenging. We are therefore, delighted that the University of Hohenheim managed to host a hybrid version of the conference from 15𝑡ℎ to 17𝑡ℎ September 2021. Being a hybrid conference, it was pleasing to note that people did not only gather in one of the lecture theatres at the University of Hohenheim but also in one of the state-of-the art seminar rooms at the Czech University of Life Sciences in Prague. The rest, of course, attended via Zoom meetings being streamed on YouTube channels using the Whova online platform.
The rise into global prominence and rapid growth of finfish and crustacean aquaculture has been due, in part, to the availability and on-farm provision of feed inputs within the major producing countries. More than 46 percent of the total global aquaculture production in 2008 was dependent upon the supply of external feed inputs. For the aquaculture sector to maintain its current average growth rate of 8 to 10 percent per year to 2025, the supply of nutrient and feed inputs will have to grow at a similar rate. This had been readily attainable when the industry was young. It may not be the case anymore as the sector has grown into a major consumer of and competitor for feed resources. This pa...
