The Collaborative Laboratory for Blue Bioeconomics (CoLAB B2E), headquartered at UPTEC Mar, in Matosinhos, Portugal, is a new non-profit association that aims to promote the blue bioeconomy, stimulate the creation of qualified jobs that generate economic and social value in Portugal in the biotechnology and aquaculture sectors, and contribute to new uses and enhancement of natural resources. Its members are the major players in the Portuguese sector: from production and distribution companies, to educational, research, associated laboratories and technological interface centers. Access2Sea partner CIIMAR is one of the founders of this Collaborative Laboratory. To know more about this CoLAB, please visit the link.
The CIIMAR PhD students’ committee is organizing the first CIIMAR students meeting entitled Blue Think Conference: Share Science, Spread Knowledge. Our aim is to gather all students affiliated with our institute in a casual and relaxed environment to share the outputs of our works. The presentations will be divided into three sessions that will be framed in the scope of CIIMAR three main research lines, each session will count with the presence of renowned scientists who will talk about their scientific careers, professional experiences and most important work achievements.
This event will take place on 17th September 2020, from 2 p.m. until 7 p.m. Considering the current Covid-19 situation, we are now preparing to host the event on an online streaming platform and simultaneously in the CIIMAR main building.
Submission of abstracts and registration are open until july 17!
The FeedMi Consortium aims to develop tools to optimize fish production in recirculating aquaculture systems on an industrial scale .
At a time when aquaculture production seeks to respond to global fish consumption demands, the FeedMi project aims to optimize farming practices and improve the health and well-being of fish in aquaculture systems with water recirculation, largely promoting environmental sustainability of these production systems.
The main objective is to develope a set of nutritional and management tools to optimize the production of several fish species on an industrial scale using recirculating aquaculture systems. FeedMi project responds to the quality concerns of aquaculture products both in terms of respect to the nutritional quality and well-being of species as well as the sustainability of production. Within this “toolbox” is the development of functional diets for larvae and juveniles of sole, goldfish and sea bass that improve their immunocompetence and that promote resistance to stress and pathogenic bacteria. The project also seeks to develop computer models that allow the adaptation of diets to the nutritional needs of these species, the optimization of water quality and modulation of the microbial biofilter, in order to promote animal welfare and the environmental sustainability of aquaculture systems.
The FeedMi consortium is coordinated by SPAROS Lda., and integrates several partnerships as the Interdisciplinary Centre of Marine and Environmental Research of the University of Porto (CIIMAR-UP), Safistela SA, the Portuguese Institute of the Sea and the Atmosphere (IPMA) and the University of Porto (Faculty of Sciences (FCUP) and Institute of Biomedical Sciences Abel Salazar (ICBAS)).
The FeedMi project is funded by Compete 2020, CRESC Algarve 2020, Portugal 2020 and the European Regional Development Fund.
Researchers from the Interdisciplinary Center for Marine and Environmental Research at the University of Porto (CIIMAR-UP), Portugal and the Abel Salazar Institute of Biomedical Sciences (ICBAS-UP), Portugal discover that marine hydrolysates can be a good option to improve European sea bass plant diets in aquaculture increasing its growth and immune response.
Vegetable proteins have been a very importante for the aquaculture industry, at a time when the availability and prices of fish meal and fish oil are so volatile that make the production of carnivorous species such as Atlantic salmon, sea bass or sea bream, completely unsustainable. However, the vegetable raw materials used in the diets of these species have not been able to supply all the nutritional needs of the organisms leading to a decrease in the immune response of the fish, as well as in its productive performance. Thus, there continues to be a high dependence on marine ingredients in the design of diets for aquaculture.
In the study led by CIIMAR and ICBAS, recently published in the international scientific journal Aquaculture, in Open Access, the work team describes promising data on the immune response and growth of European sea bass (Dicentrarchus labrax) when hydrolysates of Peruvian anchovy and giant squid are used to strengthen diets rich in vegetable proteins.
According to the results obtained, some hydrolysates, managed to mitigate the negative effects caused by vegetable proteins in the diet fish, improving their immune status and promoting growth. In vitro tests showed that, in general, all marine hydrolysates conferred resistance against pathogens in fish, especially against bacteria belonging to the Vibrionaceae family. In vivo tests showed that the addition of 3% of marine hydrolysates could replace 12.5% of fish meal in vegetable diets, leading to an improvement in the immune response and the growth of European sea bass. This study thus presents an excellent option to consider in the production of more sustainable diets for aquaculture. It should also be noted that these hydrolysates can be obtained from less noble components of animals (by-products) contributing to the promotion of a circular economy.
