“…The first concerns the synchronization process as a direct consequence of the sensitivity of each individual to hydrodynamic pressure, through the lateral line. This lateral system has been shown to play an important role in the cohesive behaviour of swimming fish [8], and more particularly in a population of H. bleheri [18]. Together with vision, sensitivity to pressure fluctuations is thus the principal mode of interaction between neighbours in the present experiments.…”

“…As evoked above, H. bleheri use the lateral line to sense the presence of their nearest neighbours. This lateral line, for most species and in particular for H. bleheri and other Hemigrammus species, is located all along the sides of the fish but does not penetrate in the caudal fin [18,[26][27][28]. The zone near the caudal fin is however the region where pressure fluctuations are focused, due to the specific swimming kinematics.…”

“…In the light of the previous observations, assuming that highly shoaling fish hold the distance to their nearest neighbours [8,18], the spatio-temporal pattern seems to be imposed by the transfer of pressure information from one individual to the other. An isolated pair of swimming H. bleheri is then characterized by a side-by-side pattern, shifted to install an efficient transfer between the pressure source (the swimming fish) and the sensor (through the lateral line).…”

In this work, we address the case of red nose tetra fish Hemigrammus bleheri swimming in groups in a uniform flow, giving special attention to the basic interactions and cooperative swimming of a single pair of fish. We first bring evidence of synchronization of the two fish, where the swimming modes are dominated by 'out-phase' and 'in-phase' configurations. We show that the transition to this synchronization state is correlated with the swimming speed (i.e. the flow rate), and thus with the magnitude of the hydrodynamic pressure generated by the fish body during each swimming cycle. From a careful spatio-temporal analysis corresponding to those synchronized modes, we characterize the distances between the two individuals in a pair in the basic schooling pattern. We test the conclusions of the analysis of fish pairs with a second set of experiments using groups of three fish. By identifying the typical spatial configurations, we explain how the nearest neighbour interactions constitute the building blocks of collective fish swimming.

“…Both channels have different properties: they act respectively at long and short range, vision operates in both the near and far field, whereas the lateral lines are limited to the near fields; and they also depend on the physical context (light, opacity, water flows). And both seem equally crucial [105], as a lateral line-disabled fish will not be able to school [103] and a blind fish will not be able to join its school if he loses its wake [102]. More important than the physiological processes involved in the acquisition of information is the kind of information a fish acquires and how it maps these estimates to motor control programmes.…”

“…The main sensory channels involved in schooling are vision [101] and the lateral line used to detect movement and vibration in the surrounding water [102,103] (see von der Emde et al [104] for physiological and ecological considerations). Both channels have different properties: they act respectively at long and short range, vision operates in both the near and far field, whereas the lateral lines are limited to the near fields; and they also depend on the physical context (light, opacity, water flows).…”

From behavioural analyses to models of collective motion in fish schools

Fish schooling is a phenomenon of long-lasting interest in ethology and ecology, widely spread across taxa and ecological contexts, and has attracted much interest from statistical physics and theoretical biology as a case of self-organized behaviour. One topic of intense interest is the search of specific behavioural mechanisms at stake at the individual level and from which the school properties emerges. This is fundamental for understanding how selective pressure acting at the individual level promotes adaptive properties of schools and in trying to disambiguate functional properties from non-adaptive epiphenomena. Decades of studies on collective motion by means of individual-based modelling have allowed a qualitative understanding of the self-organization processes leading to collective properties at school level, and provided an insight into the behavioural mechanisms that result in coordinated motion. Here, we emphasize a set of paradigmatic modelling assumptions whose validity remains unclear, both from a behavioural point of view and in terms of quantitative agreement between model outcome and empirical data. We advocate for a specific and biologically oriented re-examination of these assumptions through experimental-based behavioural analysis and modelling.
