“…The granulometric sediment composition seems to be an essential driver for the occurrence and distribution of polychaetes and fish. Association of polychaetes with sediment granulometry has been reported in previous studies that also pointed out that water physicochemical variables seem to play a minor role in polychaete distribution (Aguiar et al, 2020;Silva et al, 2017;Yeung et al, 2010). Differences in sediment type are crucial for most benthic animals, as their feeding strategies tend to be highly adapted to sediment granulometry (Yeung et al, 2010).…”

“…In contrast, invertebrates are relatively more sessile, thus better reflecting local conditions (Kilgour & Barton, 1999). Aguiar et al (2020) also assessed the environmental and biological relationships between fish and invertebrates in tropical marine environments and also did not observe a clear relationship between fish and invertebrates. In addition, these two taxonomic groups were influenced by the same environmental abiotic variables but responded differently.…”

“…If there is a close correlation or concordance between these two taxonomic groups, one could evaluate one or another group, to understand the local dynamics, which would be faster and less expensive. The impacts on benthic communities seem to be predictive of impacts on other ecological groups, such as fish, reflecting on their diversity and abundance (Aguiar et al, 2020; Maia et al, 2018).…”

“…Fish and invertebrates are taxonomic groups occupying different compartments in coastal environments and are expected to respond differently to environmental conditions. Fish were influenced mainly by the physicochemical variables, being positively correlated with salinity and dissolved oxygen, and negatively with temperature, whereas invertebrate richness was related mainly to granulometric variables, decreasing in fine and very fine sediment (Aguiar et al, 2020). Fish and invertebrate richness in Mediterranean rivers were not correlated across sites, with the Mantel test has showed no significant correlation between these two groups after controlling for the effects of environmental variables and site proximity (Larsen et al, 2012).…”

“…They are important feeding resources for several fish species and have an important role in the transfer of energy to coastal ecosystems because of their contribution to the fish diet (Guedes et al, 2015; Rosa et al, 2008; Yeung et al, 2010). The Polychaetae families Syllidae and Dorvilleidae predominated in semi‐protect beaches of the Sepetiba Bay, a tropical estuarine area in southeastern Brazil, and are influenced by different environmental variables, but no significant correlation was found between invertebrates and fish (Aguiar et al, 2020). When present in high densities, fish seem to have a strong impact on Hediste diversicolor , one of the most important polychaete species that is prey for a variety of fish in many temperate estuaries (Rosa et al, 2008).…”

The distribution of species depends on the relationship with other species and the influence of abiotic factors, modulated by long‐term evolutionary and biogeographic processes. Polychaetes and fish are important components of the biota that inhabit estuarine systems, coexisting in various habitats, although the relationship between these groups and their responses to environmental variables is poorly understood. This study aimed to assess the concordance between fish and polychaete communities in three zones (inner, middle, and outer) of a tropical bay and to determine environmental influences on these communities. The raised hypothesis is that benthic fish is associated with polychaetes and that these taxonomic groups respond differently to environmental conditions. Environmental characteristics were the main drivers determining the occurrence of fish species and polychaetes families; however, no consistent relationship was observed between fish and polychaetes. Sediment granulometry seems to be an essential driver in determining polychaetes and fish distribution while turbidity and phosphorus were also important for fish. The three zones differed in both water physicochemical and sediment (nutrients and granulometry) variables, which determined their uses by different fish and polychaetes species. Only one fish species, the gerreid Eucinostomus argenteus showed a weak but significant association with the Goniadidae and Spionidae polychaetes, which may be associated with similar environmental preferences of both taxa. The lack of a consistent relationship between benthic fish and their likely invertebrate prey may be associated with the small spatial scale of this study and the early fish life stages. Most fish in shallow coastal areas are still in their early life, feeding mainly on polychaetes and other benthic macroinvertebrates, and as the area is shallow, planktonic organisms may be included in their diet, thus relieving predation pressure on benthic organisms. These findings are important to unveil relationships among different taxonomical groups and their environment.

Macroinvertebrates metrics are reliable indicators to assess the environmental quality and ecological health. In water systems, estuarine areas are sinks and sources of nutrients and pollutants, and strongly influenced by anthropogenic activities and emission from inland. Benthic macroinvertebrates and zooplankton living in estuary and coastal are not very active organisms hence heavily impacted by surrounding environmental conditions. In this study, we assessed the water quality at the tropical coastal of Can Gio located in Southern Vietnam, based on the aquatic invertebrates and environmental variables. The organisms were monitored at 20 sampling sites along the Can Gio coastal in November 2021, April, June and August 2022. Totally, 45 invertebrate species were recorded in the Can Gio coastal. The zooplankton and benthic macroinvertebrate abundance, respectively, varied between 900 to 13,000 individuals/m3, and ranged from 30 to 120 individuals/m2. The copepods and polychaetes were dominant in both species number and abundance of the zooplankton and benthic macroinvertebrates, respectively. The water quality at the Can Gio coastal during the monitored period was from low pollution to high-moderate pollution based on the invertebrate structure, abundance and indices. The results also showed the correlation between environmental variables (e.g., turbidity and dissolved oxygen) and species richness and abundance of aquatic invertebrates. Our study revealed the important and valuable application of aquatic invertebrates for the environmental quality monitoring to protect the border of the most mangrove biosphere reserve in Vietnam.
