“…Comparison of fish assemblages among multiple surf zones may provide fundamental information to identify priority areas of coasts for conservation. Fish assemblages in surf zones are highly dynamic (Pinto et al, 2021) and often influenced by tides (Borland et al, 2017; Pattrick & Strydom, 2014). Our results demonstrated that fish assemblages during the neap tide had higher abundance and number of species and were more stable in assemblage structure than during the spring tide.…”

“…Surf zones also have heterogeneous and complex structures, such as offshore bars and nearshore troughs, characterized by wave conditions that provide refuges from predators (Mosman et al, 2020). Hence, surf zones serve as nurseries, refuges, foraging areas, and dispersal corridors for organisms, especially marine fishes, in their early life stages (Olds et al, 2018; Pinto et al, 2021).…”

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.

Artisanal fishing on Fernando de Noronha is directly related to fishing for bait, since commercial fishing depends on these baits. This work aimed to analyze the local ecological knowledge of fishermen about the biology and ecology of the fish species used as bait on Fernando de Noronha (state of Pernambuco - PE) to support the planning of the local activity. Data collection was carried out through interviews with semi-structured scripts containing questions about the socio-economic profile of the fishermen and the biological and ecological aspects of the species used as bait. The data were analyzed qualitatively and quantitatively, seeking to represent a consensus among the informants and to compare the local ecological knowledge with the scientific literature through the method of comparative cognition and the hypothesis test. Sixty-nine fishermen were interviewed, using false herrings (Harengula clupeola) and mackerel scads (Decapterus macarellus) as their main bait fish, in still fishing and fishing using boats. The hypothesis test, applied to the mentioned results by more than 30% of the fishermen, showed a high degree of agreement between local ecological knowledge and the scientific literature, revealing detailed knowledge of the fishermen on the biological and ecological aspects of false herrings and mackerel scads. Catching bait fish on Fernando de Noronha proved to be extremely important, both for the relationship with artisanal fishing and for the maintenance of local knowledge and culture. The results obtained in this research should foster a very much-needed dialogue between fishermen and those responsible for managing conservation units to create legal and effective mechanisms to meet the demand for bait fish used in commercial fishing and to maintain a sustainable artisanal fishing model for Fernando de Noronha.
