“…Irrespective of the actual settlement cues, it appears that juvenile butterflyfishes do discriminate among reef habitats. Larval butterflyfishes are very capable swimmers (Stobutzki and Bellwood 1997;Fisher 2005), and have welldeveloped sensory abilities to select suitable habitats (Leis and Carson-Ewart 2003). It is clear, however, that coral-feeding butterflyfishes are not restricted to only the most optimal habitats.…”

Many coral reef fishes exhibit distinct ontogenetic shifts in habitat use while some species settle directly in adult habitats, but there is not any general explanation to account for these differences in settlement strategies among coral reef fishes. This study compared distribution patterns and habitat associations of juvenile (young of the year) butterflyfishes to those of adult conspecifics. Three species, Chaetodon auriga, Chaetodon melannotus, and Chaetodon vagabundus, all of which have limited reliance on coral for food, exhibited marked differences in habitat association of juvenile versus adult individuals. Juveniles of these species were consistently found in shallow-water habitats, whereas adult conspecifics were widely distributed throughout a range of habitats. Juveniles of seven other species (Chaetodon aureofasciatus, Chaetodon baronessa, Chaetodon citrinellus, Chaetodon lunulatus, Chaetodon plebeius,Chaetodon rainfordi, and Chaetodon trifascialis), all of which feed predominantly on live corals, settled directly into habitat occupied by adult conspecifics. Butterflyfishes with strong reliance on corals appear to be constrained to settle in habitats that provide access to essential prey resources, precluding their use of distinct juvenile habitats.More generalist butterflyfishes, however, appear to utilise distinct juvenile habitats and exhibit marked differences in the distribution of juveniles versus adults.

“…To enter an estuary, larvae may rely on passive transport (Jenkins et al 1997(Jenkins et al , 1999 or some form of active behaviour, such as selective tidal stream transport (Forward et al 1998(Forward et al , 1999 or active swimming (Trnski 2002, Leis & Carson-Ewart 2003. Once in the estuary, high levels of swimming performance may be required both to prevent larvae from being advected out of the estuary and to find and settle in a suitable habitat (Montgomery et al 2001).…”

Critical swimming speed (U crit ) provides a useful estimate of maximum swimming performance for fish larvae that can be used to assess transport and migratory potential. We measured U crit of red drum Sciaenops ocellatus larvae through its ontogeny and compared the swimming performance of laboratory-reared larvae to that of wild-caught individuals. U crit increased with ontogeny (size), even though variability in U crit at any ontogenetic state was large. U crit for wild-caught larvae increased from 9.7 to 22.2 cm s -1 over the range of 8.3 to 16.3 mm TL and from 1.1 to 20.5 cm s -1 over the range of 3.0 to 19.1 mm TL for reared larvae. The ontogenetic increase in critical swimming speed occurred in 2 phases -an early phase of rapid improvement and a later phase of slower improvement. This sharp change in the trajectory of swimming performance coincided with important changes in ecology, morphology, and hydrodynamics. During the early phase, larvae were pelagic, their growth was highly allometric, especially in the caudal region, and they swam in the inertial hydrodynamic regime. The onset of the later phase coincided with settlement into seagrass beds, isometric growth, and inertial effects on locomotion. Wild larvae generally exhibited greater values of U crit than reared larvae of a comparable size, but the difference was not statistically significant. The results of this comparison imply that research on reared larvae may provide naturalistic results for swimming performance and that hatchery-produced larvae may perform certain behaviours well when released into the wild.KEY WORDS: Scaling · Ontogeny · Swimming performance · Settlement · Hydrodynamics · Wild larvae · Reared larvae Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 384: [221][222][223][224][225][226][227][228][229][230] 2009 important question is whether the behaviour, or specifically swimming performance, of reared larvae is similar to that of wild larvae. From the available data, the answers are mixed. It is generally agreed that behaviours with a learned component, such as anti-predator behaviour, will differ between wild and reared individuals because larvae from the 2 sources have very different experiences (Olla et al. 1998, Brown & Laland 2001). However, some tested behaviours present contradictory results. For example, reared fish may swim faster, slower, or they may have performances equivalent to wild fish, with ontogenetic variations further complicating this picture (von Westernhagen & Rosenthal 1979, Danilowicz 1996, Smith & Fuiman 2004). The same is true for other behaviours. So, when using results from reared individuals, it is desirable to compare the behaviour of these larvae to that of wild fish, especially if the results will be used to make inferences about fish in nature (Leis 2006).Some fishes that breed in coastal marine waters use estuaries as nursery habitat for their late-stage larvae and juveniles. To enter an estuary, larvae may rely on passive transport (J...

“…Mouritsen et al (2013) suggested that the response evolved to counteract the prevailing NNW current. It was demonstrated that the O. doederleini larvae were navigating using a sun compass mechanism (Mouritsen et al, 2013) and sun compass orientation has also been documented in other coral reef fish species (e.g., Leis and Carson-Ewart, 2003;Berenshtein et al, 2014). Bottesch et al (2016) demonstrated that newly settled O. doederleini at OTI can also orient their swimming to the SE at night via a magnetic compass mechanism.…”

“…The larvae of many fish species can maintain swim speeds that exceed local mean current speeds for extended periods of time, they can, therefore, influence their dispersal trajectories (Fisher, 2005;Leis, 2006). They can also orient to reefs using a variety of senses including a sun compass (e.g., Leis and Carson-Ewart, 2003;Mouritsen et al, 2013) and a magnetic compass (e.g., Bottesch et al, 2016) for long distance orientation, and hearing (e.g., Mann et al, 2007;Wright et al, 2010) and chemotaxis (e.g., Gerlach et al, 2007;Dixson et al, 2008;Paris et al, 2013) when they are closer to reefs. The exceptional swimming and orientation abilities of reef fish larvae, in combination with hydrodynamic retention mechanisms near reefs, may prevent the expatriation of some larvae away from natal reefs (Almany et al, 2007;Andutta et al, 2012).…”

Wind Conditions on the Great Barrier Reef Influenced the Recruitment of Snapper (Lutjanus carponotatus)

et al. 2018

Most coral reef fishes have a pelagic larval stage before recruiting to reefs. The survival of larvae and their subsequent recruitment can drive the dynamics of reef populations. Here we show that the recruitment of the snapper Lutjanus carponotatus to One Tree Island in the Capricorn Bunker Group, in the southern Great Barrier Reef, was highly variable over 23 years. We predicted that the currents in the Capricorn Bunker Group, including their wind driven components and the Capricorn Eddy (a nearby transient oceanic eddy), would affect patterns of recruitment. A biophysical model was used to investigate this prediction. L. carponotatus were collected from One Tree Island and the dates when they were in the plankton as larvae were determined from their otoliths. The winds present during the pelagic phases of the fish were examined; they were found to have survived either longshore (SSE) winds that induced little cross shelf movement in the larval plume or cross shelf (ENE) winds that induced little longshore movement. The unidirectional transportation of the larval plume in these conditions was favorable for recruitment as it kept the plume concentrated in the Capricorn Bunker Group. These winds were more prevalent in the periods of peak L. carponotatus production that preceded high recruitment. Dispersal under average winds (6.2 m s −1 from the prevailing ESE) and strong winds (velocity 1.5 times average), with and without the Capricorn Eddy, was also modeled. Each of these combinations were less favorable for recruitment than the longshore and cross shelf winds larval L. carponotatus survived before reaching OTI. The larval plume was comparatively less concentrated in the Capricorn Bunker Group under average winds. Strong winds transported the larval plume far longshore, to the NW, away from the Capricorn Bunker Group, while the Capricorn Eddy transported larvae seaward into oceanic waters. Larval swimming could counteract these dispersive forces; however, significant dispersion had occurred before larvae developed strong swimming and orientation abilities. This study provides a physical proxy for the recruitment of snapper. Further, we have demonstrated that great insights into recruitment variability can be gained through determining the specific conditions experienced by survivors.
