Who are the first ancestors of present-day fish?

PRESS RELEASE - What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the "bony-tongues" or the "eels", was the oldest. A study by INRAE, the CNRS, the Pasteur Institute, Inserm and the Muséum National d'Histoire Naturelle, has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of "Eloposteoglossocephala". These results, published in Science, shed new light on the evolutionary history of fish.

[Press release] Rainbow trout can recognize their own

After a period of training using a device that associates self-feeders positioned in front of visual stimuli displayed on a screen, rainbow trout were able to discriminate images of conspecifics from an abstract shape or objects.

[PRESS RELEASE] AQUAEXCEL3.0: A project to boost European aquaculture research

Where does your seafood come from? In Europe, some 75% of such products are imported, so it is important to ensure the long-term sustainable growth of aquaculture in Europe. That is the mission of the H2020 AQUAEXCEL project, which began in 2011 and is now evolving into its third incarnation: AQUAEXCEL3.0. This INRAE-coordinated European research infrastructure project brings together 22 partners, including Ifremer and the University of Lorraine, which coordinate a network of 40 aquaculture experimentation facilities in 11 different countries. The network makes it possible to carry out biological and technological experiments on all the species and farming systems used by European aquaculture. Research infrastructure projects play a vital role in structuring European research efforts.

The birth of a male sex chromosome in Atlantic herring

PRESS RELEASE - The evolution of sex chromosomes is of crucial importance in biology as it stabilizes the mechanism underlying sex determination and usually results in an equal sex ratio. An international team of scientists, led by researchers from Uppsala University, reports now how they have been able to reconstruct the birth of a male sex chromosome in the Atlantic herring. The male-specific region is tiny and contains only three genes, a sex-determining factor and two genes for sperm proteins. The study is published today in PNAS.

A cell process newly discovered in fish has important implications for medical research and aquaculture

Chaperone-mediated autophagy (CMA) plays a major role in the regulation of cell metabolism and function. To date, this cellular function is presumed to be restricted to mammals and birds. However, a team of researchers from INRAE (LPGP, NUMEA), the University of Pau and the Pays de l'Adour, CNRS and the University of Bordeaux* challenged that view and demonstrated the existence of CMA in fish. Beyond shedding new light on the evolutionary history of CMA, their findings, published in the journal Molecular Biology and Evolution on June 9, have major implications for aquaculture and medical research.

The sequencing of an "ancient" fish genome reveals an original evolution mechanism

The sterlet's genome sequencing has revealed an original mechanism of its genome evolution. It also makes it possible to take an important step forward in the management of lifestock populations.
