New short profile in our FishEthoBase!

Aiming to give informed recommendations on how to improve fish welfare in captivity, it is important to be based on scientific knowledge about natural needs and behaviour in the wild and under farming conditions of these animals. Thus, we created the FishEthoBase, an online open access database that systematically assemble ethological scientific knowledge on fishes and other aquatic farmed animals worldwide in profiles of these species.

And now we have one more profile published in our FishEthoBase! It is a short profile of Huso dauricus, a sturgeon fish primarily cultured for caviar production. Such profile was authored by MarĂ­a Cabrera, revised by Pablo Arechavala and revised and edited by Jenny Volstorf.

You can access the new short profile in the Acipenseridae family at our database here

Russian sturgeon (Acipenser gueldenstaedtii)

Russian sturgeon (Acipenser gueldenstaedtii) is a very endangered species that is cultured for restocking but also for food, both for its meat and for caviar production. Despite that, many aspects of its biology and of its production are still unknown or unavailable.

However, we already know that spawning induction under farming conditions can be highly invasive, including biopsy or endoscopy of females! But we also know that it is possible to use more modern and less invasive techniques to improve the welfare conditions related to spawning of this farmed fish. Moreover, providing proper substrate for this species under farming conditions is very important, especially because all ages seem to use substrates in different ways!

New short profile in our FishEthoBase!

Our FishEthoBase is continuosly growing. Last week we published the short profile of the silver carp (Hypophthalmichthys molitrix), one of the four Chinese major carps, together with bighead carp (Hypophthalmichthys nobilis), grass carp (Ctenopharyngodon idella) and black carp (Mylopharyngodon piceus), which were already published as short profiles in our database.

FishEthoBase is the first online and open access database to assemble ethological scientific knowledge on farmed fishes systematically, which targets scientists and practitioners, but also NGOs, the general public, and other possible stakeholders. The new short profile of silver carp was authored by Caroline Marques Maia, revised by Pablo Arechavala and revised and edited by Jenny Volstorf.
