“…Seawater hydrographic features were kept relatively similar during autumn and winter, as well as the estimated size-at-hatch and growth rates of larval A. crinitus . For cryptobenthic fish species, larval growth rates seem to vary at larger temporal scales, such as in stargazers (family Dactyloscopidae, Rodríguez-Valentino et al ., 2015; Castillo-Hidalgo et al ., 2018). The lack of seasonality in the early life history traits of A. crinitus may be linked to the environmental stability of the water column structure.…”

The early life history traits of the labrisomid blenny Auchenionchus crinitus (Jenyns, 1842) from subtidal rocky reefs were studied, based on microstructure analysis of sagittae of their pelagic larvae (4.01 mm NL −12.50 mm SL). Ichthyoplankton was collected in shallow (<20 m) nearshore waters off Isla Santa María, Antofagasta, northern Chile every 15 days during austral autumn–winter 2014 (five sampling days). During late May and early June, larval abundance was low (median ± MAD, 39.06 ± 5.08 ind. 100 m−3), increasing significantly during mid-June to early August (110.98 ± 47.66 ind. 100 m−3). Using 354 sagittae, the back-calculated hatch dates indicated the occurrence of three hatching events, two in autumn and one in winter. Hatching occurred mainly during the illuminated phases of the lunar cycle. All three batches had similar estimated larval sizes at hatch (3.2–3.7 mm SL), as well as similar growth rates (0.19–0.22 mm day−1) during the first 30 days of life. During the study period, shallow waters were well mixed, with seawater temperature of 14.73 ± 0.58°C and salinity of 34.84 ± 0.04. This is the first estimation of early life history traits of this cryptobenthic species from rocky reefs of Chile.

“…Growth rates estimated for larval A. crinitus were similar to those described for other cryptobenthic fish larvae (clingfishes, Contreras et al ., 2013; triplefin, Palacios-Fuentes et al ., 2014; sand stargazer, Rodríguez-Valentino et al ., 2015) and adults (e.g. gobiids Eviota spp., 0.20–0.25 mm day −1 , Depczynski & Bellwood, 2006).…”

“…Recent studies have shown that littoral species from the Humboldt Current Ecosystem (HCS) display lunar and semi‐lunar hatching events, particularly in fishes from families Tripterygiidae (threefin blennies), Gobiesocidae (clingfishes) and Dactyloscopidae (sand stargazers) (Contreras et al ., ; Palacios‐Fuentes et al ., ; Rodríguez‐Valentino et al ., ). Other species show a reduction of hatching events during the new moon, such as the labrisomid blenny Auchenionchus crinitus (Jenyns 1841) (Landaeta et al ., ).…”

“…Other species show a reduction of hatching events during the new moon, such as the labrisomid blenny Auchenionchus crinitus (Jenyns 1841) (Landaeta et al ., ). However, the hatching pattern may vary at seasonal and inter‐annual scales (Castillo‐Hidalgo et al ., ; Rodríguez‐Valentino et al ., ). Taking into account these results, it is plausible that diet of early life stages of littoral fishes from HCS may be influenced by the lunar cycle.…”

The influence of the lunar cycle on the feeding habits, feeding success and selectivity was tested in situ on larval stages of the clingfish Gobiesox marmoratus (Gobiesocidae). Gobiesox marmoratus larvae and their prey were collected in the water column during the lunar cycle in austral spring 2015 and 2016, in shallow waters (<30 m depth) of El Quisco, central Chile. Feeding incidence was high (80-100%) throughout the moon cycle. The diet was composed of 32 prey items, being gastropod larvae and invertebrate eggs the most important. Prey composition varied among lunar phases with the lowest prey richness during new moon. During 2016, G. marmoratus larvae ingested the lowest number, but the largest prey during new moon. In spring 2015, there were no significant changes in the abundance of each prey taxon in the water column among moon phases, but in spring 2016 there were significant differences in the abundance of cypris and copepod nauplii, particularly between full and new moon. Feeding selectivity index showed that gastropod larvae were positively selected throughout the lunar cycle during spring 2015. In spring 2016, invertebrate eggs were selectively ingested in full moon and third quarter, but at a new moon G. marmoratus larvae selected gastropod larvae. Mean temperature of the water column and its vertical gradient and nocturnal cloud cover influences the feeding success of larval G. marmoratus. Lunar illumination favoured only an increase of richness of prey items. Therefore, nocturnal cloud cover precludes a greater influence of lunar illumination in the larval trophic ecology of this cryptobenthic fish.

“…For example, hake, Merluccius gayi Guichenot, 1848, change their spawning location, egg size and the vertical migration pattern of their larvae between the main (spring) and secondary (early autumn) reproductive seasons (Landaeta & Castro, 2012). Among ELT, hatching patterns, growth and survival have crucial importance in determining the recruitment level of year classes in fish populations (Watanabe et al ., 2014) and may vary at differing temporal and spatial scales (Plaza et al ., 2003; Rodríguez-Valentino et al ., 2015). Additionally, developmental instabilities (i.e.…”

Early life traits (ELT) of the sand-burrowing cryptic marine fishSindoscopus australis(family Dactyloscopidae) were compared between cohorts hatched during winter and spring 2013, in nearshore rocky reefs off central Chile. Pelagic larvae were similarly abundant during both periods, but larger larvae were collected during austral spring. The sagittal otolith microstructure and size analyses also indicated that size-at-hatch was larger (4.7 mm) for the winter cohort, but winter larvae experienced slower growth rates (0.145 mm day−1± 0.008). Conversely, larvae from the spring cohort hatched at smaller sizes (2.9 mm), but they grew faster (0.182 mm day−1± 0.008). Hatching periods were coupled with the lunar cycle; in winter, hatching events were related to neap tides (first and third quarter moon), increasing chances of self-recruitment. Meanwhile, during spring, hatching occurred during spring tides, particularly over the new moon, decreasing chances of larval mortality by predation. Otolith traits used to test asymmetry among cohorts showed inconsistent results. Only sagittal perimeter presented fluctuating asymmetry, showing higher variance for the winter cohort. We conclude that this burrowing species displays different reproductive tactics at a seasonal scale.
