Recipe for premium serradela: aquaculture integrated with fish production


A study carried out by CESAM concludes that the production of serradela in aquaculture associated with the intensive production of fish originates more nutritious and more abundant earthworms, contributing to the elimination of the excess of particulate organic matter in the water that results from the fish production. The serradela is one of the main baits in fishing and is used for fish food in aquaculture. The conclusions are set out in the scientific article titled "Adding value to ragworms (Hediste diversicolor) through the bioremediation of a super-intensive marine fish farm" highlighted as "Feature Article" in the February "Aquaculture Environment Interactions" journal.

A lesson given by Tropical bats: a varied diet is key to species diversification


An important step was taken in understanding the ancestral but poorly understood relationship between food and species diversification through the study of the diet of South American noctilionoid bats. In the case of this bat, which divides into more than 200 species in an unparalleled diversity among mammals, the team assert that their varied diet is the key to explain the enormous genetic diversification. Until now, studies with birds and mammals have suggested that exclusively herbivorous feeding increases the rate of formation of new species. However, for omnivores - animals that include plant and animal products in their diet - there was no clear pattern: in some bats, a diversified diet seems to slow the rate of species formation, while in ungulate mammals such as deer or antelope, the opposite occurs. This study, recently published in the journal Ecology Letters, has elucidated the relationship between the type of diet and the formation of species. This research shows that in nytilionoid bats, a group of more than 200 species that inhabit the tropics of the New World, lineages with an omnivorous diet produce more long-term generations than lineages that feed strictly on plants or other animals.

CESAM article selected for "Feature Article" of Aquaculture Environment Interactions


The article is entitled "Adding value to ragworms (Hediste diversicolor) through the bioremediation of a super-intensive marine fish farm" and was developed under the scope of the PhD thesis of Bruna Marques, member of CESAM.

This publication illustrates the group's strategic focus on developing innovative solutions for more sustainable aquaculture and for adding value to aquaculture products.

SmartBioR. This is the name of an innovative program in the context of the sustainable use of Marine Biological Resources presented by the University of Aveiro

The University of Aveiro marks the Day of the Sea with the launch of a program for the Enhancement of Endogenous Marine Biological Resources - SmartBioR. The event was held at ECOMARE, Laboratory for Innovation and Sustainability of Marine Biological Resources of the University of Aveiro, and counted, among others, the presence of the Rector of the University of Aveiro Prof. Doctor Manuel António Assunção, Prof. Dr. Amadeu Soares, Director of the Biology Department of the University of Aveiro and responsible for the project, Prof. Dr. Rui Pedrosa, Vice-President of the Polytechnic Institute of Leiria, Dr. Isabel Damasceno, from Comissão de Coordenação e Desenvolvimento Regional do Centro and representatives from Grupos de Ação Costeira / Desenvolvimento Local de Base Comunitária, between Aveiro and Peniche coastal area, and the Portuguese Environment Agency (APA-ARH Centro).

Coordinated by the University of Aveiro and developed in partnership with the Leiria Polytechnic Institute, the SmartBioR program aims at the sustainability, preservation and valorization of endogenous marine resources, using scientific knowledge of excellence and technological innovation for its monitoring and integrated management . To this end, we highlight the hiring of highly qualified human resources, holders of scientific knowledge that complement the valences, already consolidated, of the institutions involved. Research and innovation activities are organized according to the two ecosystems corresponding to the territorial action of the members of the consortium: Ria de Aveiro, site of natura 2000 network and special protection area of ​​the EU, by the University of Aveiro and Berlengas, UNESCO Biosphere Reserve and coastal areas along the Midwest region of Portugal, by the Leiria Polytechnic Institute.

The University of Aveiro, reinforcing its mission of cooperation with society in the transfer of knowledge and technology, incorporates this idea by proposing, within the framework of SmartBioR, the development of products, processes and services that dynamize the value chains associated with resources endogenous marine ecosystems. Applications range from sustainable aquaculture, pharmaceutical, coastal management and fish stock management, to the protection of marine ecosystems.

Contributing to the Conservation and Enhancement of Marine Biodiversity is a design of the University of Aveiro, which in recent years has created infrastructures and consolidated and reinforced research teams in the area of ​​the Sea.

Enviphage project - Phages are an effective alternative to the use of antibiotics in aquaculture

Enviphage project involving Researchers from AZTI, Biopolis S.L. (Spain), University of Aveiro (Portugal) and the Aguacircia Aquaculture Company (Portugal) concluded that phages are an effective alternative to the use of antibiotics in aquaculture.

Use of natural bacteriophages, which do not affect the health of fish or that of consumers, becomes an interesting alternative to the use of antibiotics. Different research projects had obtained very promising results at laboratory level, but before being able to use bacteriophages at an industrial level, it was necessary to know about the impact of their use on the environment and the marine ecology.

The results obtained during 2017 show that the bacteria community of the intestinal tract of the fish is not significantly affected following treatment with the selected phages. It has also been shown that this treatment does not modify the marine bacteria population in the tanks on the fish farm or in the river where the fish farm is located, so it has zero impact or very limited impact on the bacterial ecology. 

Post-fire erosion mitigation work

After the fires, the concern with rain and the possible contamination of the waters grows. One of the projects to stop soil erosion is being developed in CESAM.



University of Algarve organizes conference in honor of Professor Mário Ruivo

The University of Algarve organizes a conference (November 13 and 14) in honor of Professor Mário Ruivo. In this way, it is intended to evoke the contribution of this marine biologist, honorary doctor by UAlg, for the development of marine sciences and technologies, with notable impacts at national and international level.

Adopting one of the mottos of Professor Mário Ruivo, the conference has as its motto "Sustainable development of the oceans: a useful utopia".


Adelaide Almeida, Ana Lillebo, Catarina Eira, Cristina Pita and Luís Menezes Pinheiro are attending this event as CESAM members.

José Alves (DBio/CESAM) appointed to the British Ornithologist’s Union meetings committee


José Alves, researcher at DBio and CESAM, has recently been appointed to the British Ornithologist’s Union meetings committee. The BOU is an organization with more than 150 years experience in “Advancing ornithology” and publishes one of the top ornithological scientific journals, IBIS.

As member of the meetings committee, José Alves will contribute towards the definition of priority international discussion topics regarding ecology, evolution and conservation of birds globally.

The BOU organizes themed conferences a feature that results in the outputs from these meetings providing practical guidelines for researchers, conservationists and governmental institutions. In 2018, the BOU’s annual conference will take place in 27-28 March, titled: “21st century ornithology: challenges, opportunities and decisions”. These conferences provide ample support to Early Career Researchers with reduces rates, dedicated workshops (e.g. presentation skills, social media presence) and the possibility to present your research even if it is outside the conference topic. In November the BOU organizes the first ever general ornithology Twitter conference – a unique opportunity to be updated on the most recent studies in ornithology at a very low cost, both financial and ecological #BOU17TC
