From 11th to 15th of march, the ICM and CephRes co-organize the course "Biology and care of cephalopods as experimental animals", accredited by the Federation of European Laboratory Animal Science Association (FELASA).

Cephalopods are a group of molluscs including species like the octopus, squid and cuttlefish, which have been included from 2013 in the European Directive on the protection and management of experimental animals for scientific purposes. This is a significant advance in the field of animal science laboratory since it is the only group of invertebrates included in this directive and represents an entire class of molluscs with about 800 described species.

In this new legislative framework, CephRes and ICM work together to offer the...

Un estudi revela l'acumulació de compostos organofosforats en els teixits de mamífers marins, concretament en dofins del Mar d'Alborán. Els científics han trobat aquests contaminants en el cent per cent dels individus analitzats, i en diferents teixits com el greix, el múscul, el fetge o el cervell dels dofins, arribant a concentracions de fins a 25 micrograms per gram de greix. Aquests nivells de contaminació són similars als trobats per altres tipus de contaminants ja legislats, com els PCB (bifenils ploriclorados) o els PBDE (polibromodifenil èters).

El treball, que compta amb la participació de Joan Giménez de l'Institut de Ciències del Mar i ha estat liderat per Ethel Eljarrat, científica de l'Institut de Diagnòstic...

ICM researchers Francesc Piferrer and Mercedes Blázquez have participated in the edition of the book Sex Control in Aquaculture, published in January.

According to the latest data from the World Food and Agriculture Organization (FAO 2018), aquaculture is the food production sector with the fastest growth (around 6% per year) and contributes more than 50 % of aquatic products consumed around the world. Among the cultivated species, the fish (54.1 million tonnes) and crustaceans (7.9 million tonnes), with an approximate market value of 175,000 million euros, stand out.

The control of the proportion of sexes in fish and crustaceans, the subject of the book, pursues different objectives. First of all, many species present a sexual dimorphism in terms of growth. Therefore, there is an interest in favoring the...

Researchers from the Institute of Marine Sciences of Barcelona (ICM-CSIC) have completed the project "Conservation and Recovery of Depth Gorgonians Populations through Ecological Restoration and Fisheries Impact Mitigation" (ResCap 2018). The project has recovered 450 gorgonians in the same areas where they were catched in fishing nets, to restore the seabed. The conditions for maximizing the growth in aquarium of gorgonian fragments have also been determined, in order to generate new individuals for the restoration of impacted populations.

The initiative has been carried out with the collaboration of the Biodiversity Foundation of the Ministry for Ecological Transition, through the Pleamar Program, co-financed by the FEMP. The main objective of the project has been to recover the deep seabed of the continental shelf...

The Raymond L. Lindeman Award honors a young scientist for an outstanding peer-reviewed, English-language paper in the aquatic sciences. The Association for the Sciences of Limnology and Oceanography (ASLO) has awarded Andrea G. Bravo, currently with a “Marie Sklodowska-Curie” post-doc position at the Institute of Marine Sciences (ICM-CSIC), the 2019 Lindeman Award for her paper, “Molecular composition of organic matter controls methylmercury formation in boreal lakes”. Bravo’s research, published in Nature Communications in 2017, challenges the traditional mercury cycle by demonstrating the role of organic matter composition on bacterial activity, and ultimately, on mercury methylation rates in boreal lakes.

“Bravo’s work has accomplished precisely what a fundamentally...
