“…According to Davis (2000b), intertidal species are usually sensitive to environmental changes caused by ENSO. Furthermore, this region is even more vulnerable due to land and sea interactions, which can affect fish populations as well as the reef system (Sanford, 1999), especially in relation to changes in fish habitat (e.g., bleaching), which may consequently alter the composition of the fish assemblage (Peiro‐Alcantar et al., 2016).…”

Tide pools are important environments for several fish species, as they offer essential resources such as shelter and food. Thus, understanding the relationships of the ichthyofauna with the habitat structural characteristics in tide pools is important to understand the distribution patterns of fish assemblages in shallow environments. This study investigated how the habitat structure in tide pools influences the reef fish assemblages in Southwestern Atlantic (Bahia, Brazil). During 17 months, tidal pools were evaluated through visual censuses aiming to sampling the ichthyofauna, and additionally, variables of the structural characteristics of the pools (depth, area, volume, rugosity, etc.) were measured. By using multiple statistical modeling approaches, we found that there were significant differences in diversity, abundance, and species richness at the interaction between time and space factors, with higher averages of the three variables during the warmer months across all reef banks. Moreover, at local spatial scale, greater coral‐dominated and complex pools harbored higher fish species and diversity, while algae cover was most important in shaping fish numbers. The most important variables in the structuring of the fish assemblages were the pool volume, distance from the edge of the reef, and habitat complexity, confirming our hypothesis. Resident fish species were found in pools near the out reef edge, while occasional and transient species were found in pools closer to the inland sea. Our study highlights the multi‐scale role of habitat characteristics as predictors of the fish assemblage structure in these extremely variable environments and emphasizes the need to protect these fragile and overexploited tidal pools.

“…Seasonal changes in ichthyoplankton assemblages in coastal and estuarine water are relatively common (Korsman, 2013;Zhang et al, 2019a;Zhang et al, 2019b;Jiang et al, 2021). Seasonal differences were also found in the California Current (Loeb et al, 1983;Moser and Smith, 1993;Peiro-Alcantar et al, 2016) and Kuroshio Current regions (Moku et al, 2003;Sassa et al, 2007b;Sassa and Hirota, 2013). Gonadal maturation and spawning of fish depend on the appropriate external environment to ensure that larvae are produced when conditions are most suitable for their survival.…”

The Philippine Sea, owing to its complicated circulation pattern and the presence of numerous seamounts, is considered to be a hotspot for biodiversity and an important fishing ground. However, to date, few studies on ichthyoplankton in the Philippine Sea have been conducted. During the summer, autumn, and winter of 2020–2021, a series of investigations were conducted to study the spatial and temporal structure of fish larvae in the Philippine Sea. A total of 65 samples were collected by vertical hauling from a depth of 200 m to the surface. A total of 882 fish larvae representing 81 distinct taxa, 49 genera, and 23 families were identified. A seasonal pattern was also observed based on the differences in abundance and dominant taxa. The abundance of fish larvae was 11.35 ± 12.46 ind./100 m3 (mean ± sd.) in summer, 5.83 ± 7.03 ind./100 m3 in autumn, and 2.57 ± 2.73 ind./100 m3 in winter. The dominant species were Vinciguerria nimbaria, Encrasicholina punctifer, and Cyclothone sp. in summer, V. nimbaria, and Ceratoscopelus warmingii in autumn, and Diaphus spp., D. garmani, and Sigmops sp. in winter. A significant latitudinal variation in fish larvae assemblages was found via cluster analysis, and two geographic groups were separated by the northern boundary of the North Equatorial Current. In addition, the fish larvae species diversity also showed a significant latitudinal gradient in autumn, which disappeared in summer. Canonical correspondence analysis indicated that the structure of fish larvae assemblages was affected by average temperature, salinity, and net primary productivity in the upper ocean and sea level anomaly. All dominant species were associated with specific niche environments. This study suggests that latitudinal zonation of fish larvae also occurs in the oligotrophic low latitude Pacific Ocean and is enhanced in autumn. These results provide multi-seasonal baseline data of fish larvae assemblage in the upper Philippine Sea, being an important reference for the planning of marine protected areas in the high seas.

“…The habitat characterization of fish larvae facilitates the identification of the key set of variables governing the permanence and distribution of organisms. It is known that in demersal fish species, larval abundance responds to seasonal variability of environmental forcing, which is closely related to reproductive periods, geographic location and potential habitat for the expansion or shrinkage of the distribution range (Bailey 1981, Funes-Rodríguez et al 2009, Peiro-Alcantar et al 2016. On the western coast of the Baja California Peninsula, larval fluctuations are related to the predominance of sub-Arctic water in winter-spring and part of summer, in addition to the warming effect of surface and subsurface counter-currents from late summer to autumn to the south of the peninsula (Durazo and Baumgartner 2002, Durazo 2015, Valle-Rodríguez and Trasviña-Castro 2017.…”

“…The demersal fish larval community in the southern portion of the California Current system is highly diverse and splits into two larval assemblages around Punta Eugenia and Bahía Sebastián Vizcaíno (28°N) (Peiro-Alcantar et al 2016). One assemblage congregates to the north, characterized by the predominance of species of sub-Arctic−transitional affinity (winter-spring).…”

“…One assemblage congregates to the north, characterized by the predominance of species of sub-Arctic−transitional affinity (winter-spring). The other appears to the south, com-posed mostly of species of subtropical affinity during summer-autumn (Funes-Rodríguez et al 2009, Peiro-Alcantar et al 2016, including some species of fishing importance (e.g., Merluccidae, Scorpaenidae, Pleuronectidae)…”

Habitat characterization provides predictive information about the distribution of species and is useful for assessing habitat quality and population stability. Larval abundance of six frequent and abundant demersal species and the relationship of each with the environment were analysed through generalized additive models to determine their preferential distribution and predictive response to the environmental variables in the southern part of the California Current (25-31°N) between two periods of data collection: 1997-2000 and 2006-2010. Essentially, the main associated variables governing the distribution patterns were related to common and oceanographic characteristics of the water column (temperature and salinity at 50 m depth, dynamic height and degree of water column stratification); however, the set of variables and their ranges are usually species-specific. Species of northern distribution, Sebastes sp. and Citharichtys stigmaeus, were recorded mainly in newly emerged, relatively unstratified waters characterized by a shallow mixed layer and low temperatures. Low dynamic height values were the most significant predictor of larval distribution for Merluccius productus. Citharichthys xanthostigma and Symphurus atricaudus were widespread, distributed across the study area mainly in autumn in unstratified or stratified waters and at a shallow mixed layer. Particularly C. Xanthostigma and S. Lucioceps were related to high dynamic height values, likely influenced by a coastal flow towards the pole, as evidenced by counter-currents.
