For animals living in groups, one of the important questions is to understand what are the decision-making mechanisms that lead to choosing a motion direction or leaving an area while preserving group cohesion. Here, we analyse the initiation of collective departure in zebrafish \textit{Danio rerio}. In particular, we observed groups of 2, 3, 5, 7 and 10 zebrafish swimming in a two resting sites arena and quantify the number of collective departure initiated by each fish. While all fish… 

Figures and Tables from this paper

Loose social organisation of AB strain zebrafish groups in a two-patch environment
The number of fish affects the behaviour of each individual in a group, the cohesion of the groups, the preferential interactions and the transition dynamics between the two rooms, and it is shown that the rankings of exit correspond to the topological organisations of the fish prior to their collective departure.
Bidirectional interactions facilitate the integration of a robot into a shoal of zebrafish Danio rerio
A behavioral model that alternates between obeying and disobeying the collective motion decisions in order to become socially accepted by the shoal members is designed and compared against two extreme cases: a reactive and an imposing decision model.
Automated Calibration of a Biomimetic Space-Dependent Model for Zebrafish and Robot Collective Behaviour in a Structured Environment
It is shown experimentally that a biomimetic multilevel and context-dependent model allows good social integration of fish and robots in a structured environment.
How mimetic should a robotic fish be to socially integrate into zebrafish groups?
This study shows that an autonomous biomimetic robot was enhanced by a biomimetics behavioural model so that it can socially integrate into groups of fish.
Automatic Calibration of Artificial Neural Networks for Zebrafish Collective Behaviours Using a Quality Diversity Algorithm
This study deals with learning how to simulate realistic collective motion of collective of zebrafish, using real-world tracking data and presents a novel approach that uses Quality Diversity algorithms, a class of algorithms that emphasise exploration over pure optimisation.
Modelling zebrafish collective behaviours with multilayer perceptrons optimised by evolutionary algorithms
It is revealed that ANN models trained using evolutionary methods are capable of generating realistic collective motions for groups of 5 zebrafish including the tank wall effects, a feature that is lacking in previous models.
Follow the dummy: Measuring the influence of a biomimetic robotic fish-lure on the collective decisions of a zebrafish shoal inside a circular corridor
A series of experiments were designed to assess the impact of some features of the lure regarding its acceptance among the fish, depending on various parameters, and the methodology presented and the experimental results are promising for the field of animal-robot interaction studies.
Evolutionary Optimisation of Neural Network Models for Fish Collective Behaviours in Mixed Groups of Robots and Zebrafish
A methodology with multilayer perceptron or echo state networks that are optimised through evolutionary algorithms to model accurately the fish individual and collective behaviours in a bounded rectangular arena is presented.
How to Blend a Robot within a Group of Zebrafish: Achieving Social Acceptance through Real-time Calibration of a Multi-level Behavioural Model
A methodology for continuous real-time calibration and refinement of multi-level behavioural model that can optimise the robot behaviours during the experiments and allows to cope with changes of dynamics in fish behaviour.
