“…In general, fish abundance and species richness are locally associated to variability in environmental conditions, mainly salinity, primary productivity and substrate type [ 55 , 72 ], which often forces a high species turnover across space in tropical estuaries. Our results of db-RDA demonstrated the influence of environmental factors on the different species of fishes in each zone (habitat conditions).…”

“…For instance, a higher abundance and richness of larvae and juvenile fishes registered in zone 3 (lower estuary) seemed to be associated primarily to (1) an increase in the influence of marine conditions [ 10 , 55 ], and/or (2) a close proximity to unstructured (beaches and mudflats) and structured habitats (seagrass beds) found in this zone [ 76 ]. Some studies conducted in the Mamanguape estuary have detected evidence of the presence of multiple habitats in the lower part of the estuary that may thus promote an increase in occurrence/abundance of fish species [ 72 , 77 ]. Furthermore, the presence of multiple habitats is known to increase feeding, sheltering and reproduction opportunities for coastal fish to maximize their probability of survival [ 12 , 87 ].…”

Estuarine fish assemblages are often sensitive to environmental conditions, because fluctuation in physico-chemical conditions at different spatial and seasonal scales can directly influence species distributions. In this way, we conducted a field survey to investigate the role of estuarine gradient (environmental heterogeneity) in fish α and β diversity. The study was carried out in three zones in Mamanguape River estuary according to salinity and geomorphology features during an atypical climatic event in 2015. In total, 18,084 specimens of 125 species were captured. Additive partitioning of diversity analysis detected a higher proportion of beta diversity among estuarine zones during the rainy (β3 = 58.6%) and dry season (β3 = 40.94%) and were higher than expected by chance (Propexp> obs <0.001). Decomposing β-diversity analysis showed that total β-diversity (βsor) results were more dominated by species turnover (βsim) than nestedness (βnes) in both seasons. Forward selection procedure and db-RDA identified salinity, coarse sand and chlorophyll-a as the main environmental variables influencing βsor and site distance from estuary mouth and split as the main landscape variables. Variation partitioning analysis revealed more contribution to the pure fraction of environmental variables to fish species turnover, however, both pure fraction of environmental and landscape variables significantly contributed to βsim. Our study highlighted the importance to environmental heterogeneity and connectivity to promote fish diversity across the Mamanguape River estuary. Thus, future conservation policies should focus on maintaining these two components to guarantee its nursery ground role to estuarine fish assemblages.

“…We categorized each species into one of the three ecotypes based on their primary habitat: (1) coral reef‐seagrass‐associated species (CS), which appear mainly in coral reefs and/or seagrass meadows; (2) mangrove‐estuarine‐associated species (ME), which are common in mangroves and/or estuaries; (3) the common coastal associating species (CO), which are common in coastal waters and large sandy shorelines (Du et al, 2020; Inui et al, 2010; Krumme, 2009; Pessanha et al, 2021; Travers et al, 2010).…”

“…An increasing number of studies (Olds et al, 2018; Pessanha et al, 2021; Pittman & McAlpine, 2003) have documented that surf zones represent a critical linkage for fish movement in typical coastal seascapes around (e.g., estuaries, mangroves, seagrass meadows, coral, and rocky reefs). Coastal seascape configuration, connectivity, and habitat complexity have a major influence on the assemblage of fishes in surf zones (Mosman et al, 2020; Nagelkerken et al, 2013; Vargas‐Fonseca et al, 2016).…”

The surf zones are significantly affected by tides, however, several gaps still in knowledge of fish assemblages in surf zones response to spring‐neap and daily tidal cycles. We investigated fish assemblages in a surf zone of Gaolong Bay in China. The dynamics of fish assemblages were examined during the neap tide and the spring tide to test the hypotheses that (1) fish assemblages reflect a combination of species from around coastal habitats, and (2) dynamics of the fish assemblages were determined by both the spring‐neap cycles and diel rhythms of fish species. We collected 46 fish species comprising 16 coral reef‐seagrass species, 24 mangrove‐estuarine species, and 6 common coastal species. Fish abundance and richness were significantly higher during the neap tide than during the spring tide. Furthermore, during the neap tide, fish assemblages were mostly carnivorous coral reef‐seagrass species at night and were mostly omnivorous and planktivorous species during the daytime. However, no clear diel patterns were observed during the spring tide. We suggested that dynamics of the fish assemblages were mainly shaped by the diurnal rhythms of fish during the neap tide and by the tidal cycle during the spring tide. Our results support the notion that surveys of fish assemblages during the neap tide could collect more abundance and rich species of multiple ecotypes of fish to evaluate fish resource status in the around coastal habitats. Consequently, management approaches around surf zones with heterogeneous seascapes can lead to positive outcomes for inshore fish resources and ecosystem conservation.

“…Compared to the diversity of fish species in other mangrove ecosystems outside the island of Sumatra found 38 species consisting of 20 families and 28 genera in the mangrove ecosystem on Lombok Island, Nusa Tenggara [17]. Mangrove ecosystems are ideal habitats for fish communities because of the availability of food needed for optimal growth and development stages [18]. Several groups of fish at the juvenile stage utilize abiotic factors such as current velocity [19], salinity [20], and mud area [21], to ensure their survival.…”

Mangrove ecosystem is one of the unique ecological niches and the ideal habitat for several groups of fishes. The total area of mangroves in Indonesia is estimated at 3,489,140.68 ha. Although many studies have been conducted, there are still many fish species of this ecosystem that have not been revealed. This study aims to determine the fish community in several mangrove hotspots in Banyuasin Regency, South Sumatra. Specimen collection was carried out in May–June 2021 by using various fishing gears including hand net, seine net, and gill net. Water parameters, e.g., pH, salinity, and temperature, were also measured. This research has succeeded in collecting 31 fish species consisting of 20 families and 26 genera with a total of 145 individuals. Gobiidae and Butidae are the two most abundant families in term of number of species with 7 and 4 species, respectively. The remaining families each were represented by 1 species. Oryzias javanicus, Planiliza subviridis, and Ambassis macracanthus had the highest relative abundance values compared to other species. This study also found the first record for Bostrychus cf. scalaris from Indonesian water which B. scalaris was previously known only from Peninsular Malaysia.
