FEB 2.0: Revised species tree

FEB 2.0: Revised species tree (2022-07-27 by Jenny Volstorf)

The revised species tree now provides an easy comparison between the FishEthoScores of the profiled species. Play around with the sorting to find the order of species with the highest probability for good welfare under minimal farming conditions (Likelihood) or under high-standard farming conditions (Potential) or with the highest certainty of these scorings (Certainty). Use mouse-over on the legend or the FishEthoScore/farm to get more information. Also via mouse-over, find highlighted by colour all those species belonging to the same family, order or class. Collapse branches of the tree with a mouse click to get better orientation.

New episodes of FishEthoBase podcast programme!

New episodes of FishEthoBase podcast programme! (2022-07-19 by Caroline Marques Maia)

FishTalk is our podcast, which is updated monthly. FishEthoBase programme at Fish Talk is composed of series of brief audios focused on fish species with profiles already published in our FishEthoBase. The idea is to give information about natural needs, behaviours or farming conditions of fishes and other aquatic farmed animals in less than 3 min.

Now we just released new episodes of FishEthoBase programme. This time the episodes are focused on Common cuttlefish (Sepia officinalis), Mexican four-eyed octopus (Octopus maya) and Common octopus (Octopus vulgaris).

If you are interested, please click here to listen to the new episodes (series 6).

Bighead carp (Hypophthalmichthys nobilis)

Bighead carp (Hypophthalmichthys nobilis) (2022-07-06 by Caroline Marques Maia)

Bighead carp, scientifically known as Hypophthalmichthys nobilis, is one of the four Chinese major carps and can be found in lakes, rivers, and reservoirs of south and central China. It is one of the most intensively cultured fishes in Asia.

As this carp is a planktivorous fish, it is reared not just for its production, but also as a filter-feeding fish in polycultures, helping to improve the water quality and controlling the phytoplankton. Bighead carp is a fast growing fish, which is also interesting for aquaculture, but this means it is usually sold before reaching maturity.

Because bighead carp can also feed on detritus and organisms living on the bottom opportunistically, it could be important to provide access to substrate for this carp in captivity, so it has more feed choices. Moreover, as it is commonly sold live or fresh locally, this fish probably dies by asphyxia, which means much suffering. As no high-standard slaughter method is available for this carp, further research about this is urgent.

Welcome to FEB 2.0

Welcome to FEB 2.0 (2022-06-12 by Sebastian Scholz)

We thought it was time to give the FishEthoBase a complete makeover. And now it's finally done: the Fish Ethology Database launches with a new base and a new look. Enjoy!
