Active habitat selection by pre‐settlement reef fishes

Our understanding of habitat selection by reef fish larvae has changed dramatically in the last 10 years. Fish larvae have long been considered passive particles at the mercy of ocean currents, tides and weather events. For reef fishes, ecological evidence has shown that passive dispersal alone often cannot explain larval distributions, suggesting active behaviour by reef fish larvae. While behaviourally modified passive transport may be important, recent work demonstrates that some reef fish larvae have the capability to actively swim to settlement habitat. They can orientate to reefs from distances of at least 1 km and can swim at speeds of 13.5 cm s−1 for several days. The question then becomes, what are the cues that fish larvae use to orientate to reefs? Ambient reef sound has been shown to be attractive to reef fish larvae, and current research aims to understand better the nature and use of these acoustic cues. Other potential cues include chemoreception/olfaction, wave cues and visual location of reefs. A better understanding of active habitat selection and the underlying sensory and behavioural mechanisms will improve our knowledge of recruitment processes in reef fish ecology, and may have implications for active management of reef fish populations.

“…Mechanical noises and the timing of the experimental events did not change with the change in paddle direction, and no conspicuous asymmetric clues were present. Thus, the change in paddle direction could be only detected by the fish by keeping track of their movements during the ITI, perhaps by kinaesthetic cues (Chapuis, 1982) or inertial integration (Barlow, 1964;Levin et al, 1989; Levin & Gonzalez, 1994).…”

Small groups of fish of a schooling species (Aphyocharax erithrurus) were trained to turn right or left in order to avoid being temporarily swept out of the water.This was achieved by a rotating avoidance paddle approaching them with one door (right or left) open. Once a learning criterion was attained, the direction of the paddle was reversed and both doors were opened. During these inversion trials, fish chose the door which was at the same side in relation to their body, showing that egocentric clues were used when facing the problem from an opposite viewpoint. When vertical black and white stripes were present at one side of the tank, a different response appeared during the inversion trials: fish passed through the door nearest to the stripes regardless of which door was open during training. It is concluded that these fish use egocentric references when the spatial problem is reversed by 180°, and that this response is overridden by a tendency to swim near a vertically striped background.

“…Given small turns, a correlated random walk can be very straight for short periods of time with or without orienting behavior. Additionally, fishes may limit the rate at which their swimming direction changes, based on endogenous inertial cues detected by the vestibular system (Harden Jones 1984, Levin & Gonzalez 1994. The implications of larvae following correlated random walk trajectories are further explored in our simulation model.…”

The supply of coral reef fish larvae from the open ocean to nearshore reefs is vital for the persistence of local fish populations. Larvae that are competent to settle are often fast swimmers, and their transport to suitable settlement habitat may depend on swimming behavior as well as currents. Our goal was to measure the effects of swimming behavior during the final period of larval transport. We observed late-stage bicolor damselfish Stegastes partitus larvae 1 km offshore of French Reef, Key Largo, Florida, USA, and recorded their in situ swimming trajectories. While all larvae swam remarkably straight, their swimming directions were distributed randomly. Larvae swam at speeds of 2 to 32 cm s -1 and transport due to swimming was of similar magnitude as transport due to cross-shore current, but much less than transport due to alongshore current. We used a simulation model to generate swimming trajectories of much longer duration than would be feasible to directly observe. This enabled us to better quantify the contribution of swimming behavior to larval transport. The observed and simulated swimming trajectories indicate that horizontal swimming by larvae with or without an external reference frame is important at spatial scales of several kilometers.
