João L. Saraiva is a fish ethologist with a special interest in welfare. He is currently leading the Fish Ethology and Welfare Group at CCMAR and is the president of the FishEthoGroup Association. With a career built on the interplay between proximate and ultimate mechanisms underlying social behaviour and chemical communication in teleosts, João now focuses on the application of fundamental science to improve the welfare of farmed fish. He was co-editor of a special issue and book on Welfare of cultured and experimental fishes. Along with his scientific production, João is also part of the team behind FishEthoBase, an open access database on welfare of farmed fish species.
A new book entitled “Welfare of Cultured and Experimental Fishes” was recently edited by João L. Saraiva and Pablo Arechavala-Lopez, researchers from the Center for Marine Sciences (CCMAR) . Fish welfare is a recent field , but is beginning to receive due attention not only from researchers, but also from consumers, industry and policy makers.
Fish Ethology and Welfare group, from the Centre for Marine Sciences (CCMAR) organized last November a unique fish welfare course, attended by some renowned international researchers in this area.
The third edition of the Summer Shoal, dedicate to fish welfare, was organized for the first time in Portugal and was a huge success.
RESEARCH TREND ALERT: Now that eco-concerns have pushed the agenda towards sustainable aquaculture, it is time to address welfare in fish farming.
CCMAR inspires is a series of events organized to nourish the curiosity of our researchers and feed the discussions on scientific topics. The first session is scheduled to next Friday, February 7th, at 5pm and Alexandre Quintanilha will talk about: “Knowledge as the basis of democracy”.
CCMAR researcher, João Saraiva, represented his work at European Maritime Day 2019.
João Saraiva is going to re-join CCMAR, leading a new research group focused in Ethology and Welfare.
Welcome back João!
Os cientistas já sabiam que muitas espécies usam a comunicação química nas suas interações sociais, mas num estudo recentemente publicado na revista Scientific Reports, um grupo de investigadores do Centro de Ciências do Mar, dá conta de que o peixe tilápia moçambicana usa estes sinais para reduzir a violência nos combates. Os cientistas reportam também que os machos ao cheirarem a urina dos dominantes aumentam as suas hormonas sexuais.
João Saraiva, researcher at CCMAR, participates in a pioneering study that aims to improve the conditions and fish welfare in European aquacultures, by giving them legal status.
An innovative study reveals that the adoption of very simple measures of environmental enrichment, which means the introduction of structures to improve the environment in the farming cages, contributes significantly to the welfare of farmed sea bream.
