HIGHLIGHTS
Improving the reproduction of the European cuttlefish, Sepia officinalis (Linnaeus, 1758) in captivity: a multidisciplinary approach.
Melhoria da reprodução do choco Europeu, Sepia officinalis (Linnaeus, 1758) em cativeiro: uma abordagem multidisciplinar.
The first ever reproduction Big Brother is on the way.
This project aims to understand the influence of several factors on the reproduction of S. officinalis, in captivity, which is currently a bottleneck. We aim to apply a multi-disciplinary approach, seeking to increase egg fecundity and fertility, minimize inbreeding and compensate semelparity by increasing intermittent spawning.
Firstly, studies will provide understanding of the influence of different zoo-technical aspects such as optimal bottom area/tank volume and density on natural occurring male/female ratio, reproductive number and behavior.
Secondly, we will identify, characterize and determine the functional sensitivity of olfactory receptor neurons and other types of cells and determine the influence of culture setup, behavior and chemical communication.
Thirdly, the impact of multiple consecutive generations and the effects of systematic line crossing will be assessed through determination of inbreeding and paternity analysis for the culture conditions to be tested.
Finally, an overview on all variable contributions and their magnitude in cuttlefish reproduction in captivity will be determined. All 3 will be accomplished through a set of trials, were data for all lines of research will be gathered.
Cuttlefish don't have an olfactory bulb, so we are identifying olfactory receptor neurons
New welfare based methods to determine sex and marking juveniles in the experiments are being assessed
