- Description of the activities of the project
- Groups of fish individuals can organize into the diversity of spatiotemporal patterns, such as schools of fish. This complex collective behaviour results from the conditional response of individuals to visual, acoustic, or chemical stimuli. Individuals change their orientation (alignment), nearest-neighbour distance, or velocity, which leads to different states such as disordered swarms, directed flocks, or rotating swirls. As a result of distributions of the individuals’ behaviour, groups can dynamically switch between states while remaining cohesive, which suggests the presence of robust cohesion mechanisms.
- Based on previous studies, we know that fishes behave differently under different environmental conditions. Thus, in this project we aim to clearly understand how fish show the diversity of the patterns. To characterize different types of behaviours under the fluctuation of environmental factors i.e. dissolved oxygen (DO) and temperature, we will describe swimming patterns and then examine the statistical shape of fish groups. In addition, we will investigate and compare small and large groups of fish schools in terms of changing environmental factors. In other words, our study asks whether and how sensory flexibility depends on the specific type of behaviour and comparing the impact of environmental change on reflexive responses and social behaviour. Using the trajectory evaluation, the behaviour of the fish could be statistically parameterized and classified. The environment of the aquarium will be artificially modified to observe fish reaction of events. Complementary, the dissolved gases diffusions will be mathematically modelled.
