“…If the observer remained motionless, the fi shes reappeared even closer to him and for a longer time, while they kept watching the observer. This "curiosity" was observed in other labrid fi shes as a curious feature among documented escape behaviour (Nunes et al 2015). These authors suggested that this behaviour might be speciesspecifi c as some species exhibited it more than others regardless of the environmental conditions.…”

Background. Little is known about the seagrass wrasse, Novaculoides macrolepidotus. In January 2012 it was recorded for the fi rst time from Reunion Island. As its population increased over the years, fi eld observations were made on colour pattern variation, escape and reproductive behaviour. Regarding a cryptic and poorly documented species, these observations, despite their anecdotal form, need to be made available to ichthyologists. The aim of the present paper was to present this fi rst record with associated fi eld observations and to increase interest of ichthyologists in this species. Material and methods. Observations were made while snorkelling on the west coast of Reunion Island on the fringing reef of L'Ermitage (district of Saint Gilles les Bains). The fi rst specimen was observed on 28 January 2012 in a monospecifi c seagrass bed of Syringodium isoetifolium. Later surveys on the same reef between 2012 and 2016 provided additional observations of the species. Results. Colour pattern and body proportions of the fi rst observed specimen well agree with N. macrolepidotus as described by Randall and Earle (2004). Subsequently observed specimens expressed a previously undescribed colour pattern variation. Escape and reproductive behaviour was observed and are discussed. Conclusion. A reproducing population of N. macrolepidotus has apparently established at Reunion Island. The present fi eld observations of the behaviour of this species should be followed by more detailed ethological studies.

“…The diver would reproduce the spearfisherman behavior (modified from JanuchowskiHartley et al, 2011JanuchowskiHartley et al, , 2012JanuchowskiHartley et al, , 2013Nunes et al, 2015). Although Januchowski-Hartley et al (2011,2013) and Nunes et al (2015) did not used scuba equipment, we decided to use scuba because it facilitates to spot the fish and kept the dives safer. The diver swam directly toward the fish at a constant speed (~0.5 m/s, measured using portable GPS at the sea surface, according to Nunes et al, 2015) using a wooden handle to simulate the spearfishing gun (Fig.…”

“…The study of Kelley & Magurran (2003) reported that the FID of fishes is influenced by previous experiences with predators (risk of predation). Moreover, other variables could be influencing a prey's escape decisions such as structural complexity, group size and body size (Gotanda et al, 2009;JanuchowskiHartley et al, 2011;Nunes et al, 2015). Thus, it is expected that in marine NTAs, where fishes are not familiar with the presence of spear fishers, the FIDs would be shorter than those in multiple-use areas (MUAs), where spearfishing (and other human activities) is frequent Januchowski-Hartley et al, 2012), even when NTAs and MUAs are close to each other (Gotanda et al, 2009).…”

Fishing pressure affects the behavior of reef fish, especially of fishery-targeted species. In this context, it is critical to understand if fish behavior is preserved in no-take areas (NTAs), which are considered the best instrument for the recovery of fish stocks. Comparing the flight initiation distances (FIDs) of fish inhabiting multiple-use areas (MUAs), where fishing is allowed (including spearfishing), and NTAs is a useful approach to test whether NTAs can be effective as fish refuges. Here, we compared whether the FIDs of two target (Sparisoma axillare and Scarus trispinosus) and one non-target (Halichoeres poeyi) labrids are greater in the MUAs than in the NTAs. We also investigated whether group size (GS) and body size (BS) exert any effect on the FID. We sampled four MUAs and four NTAs in the Abrolhos Bank (Brazil). We found that only for the targeted species FID was shorter inside the NTAs and that the BS had a positive effect on the FID of all species. The GS and BS of the fish are greater in the NTAs than in the multiple-use areas only for S. trispinosus. Our study shows that fish, especially those species that are fishery targets, display an avoidance behavior against spearfishermen likely as a consequence of fishing pressure. We suggest that the NTAs in Abrolhos are not only important sites for the recovery of fish stocks but also possibly act as a repository area of naïve fish (fish that allow human approach), for reefs open for fishing.A pressão pesqueira afeta o comportamento de peixes recifais, especialmente nas espécies alvo de pesca. Nesse contexto é importante entender se áreas fechadas a pesca ("no-take areas": NTAs), consideradas como melhor instrumento para recuperação dos estoques pesqueiros, garantem a integridade dos comportamentos dos peixes. Comparar distâncias iniciais de fuga ("fligth initiation distance": FIDs) de espécies entre recifes de uso múltiplos ("multiple-use areas": MUAs), onde a pesca é permitida (incluindo a pesca submarina), e as NTAs é uma abordagem útil para testar se as NTAs podem ser efetivas como refúgios para peixes recifais. Nesse trabalho FIDs de duas espécies alvo (Sparisoma axillare e Scarus trispinosus) e uma não alvo (Halichoeres poeyi) foram comparadas entre MUAs e NTAs. A possível influência do tamanho do grupo ("group size": GS) e o tamanho do corpo ("body size": BS) sobre FID também foram investigados. Foram amostradas quatro MUAs e quatro áreas NTAs no banco dos Abrolhos (Brasil). Nossos resultados mostraram que apenas FID das espécies alvo de pesca foi menor dentro de NTAs e que o BS teve um efeito positivo no FID de todas as espécies. Dentro da NTA, GS e BS foram maiores do que em recifes abertos à pesca apenas para S. trispinosus. Finalmente, sugerimos que NTAs em Abrolhos não são apenas importantes como recuperação dos estoques pesqueiros, mas estão possivelmente atuando como uma área repositória de peixes "ingênuos" (peixes que permitem aproximação humana) para os recifes onde a pesca é permitida.

This paper presents a checklist of the reef fish fauna of the Anchieta Island State Park, a no-take zone in which no extractive activities are allowed, in Ubatuba, Southeastern Brazil. Data was obtained between 2011 and 2013, mainly through underwater observations with snorkelling and SCUBA, and secondarily using scientific fishing (trawling). Published and unpublished data were also verified and compiled. A total of 103 reef fish species, distributed in 78 genus and 50 families was recorded. Haemulidae was the richest family (n=7 species), followed by Epinephelidae (n=6), Pomacentridae, Carangidae and Tetraodontidae (n= 4 each). Haemulon was also the most speciose genera (n=5), followed by Stegastes, Acanthurus and Mycteroperca (n=3 each). Sixty-nine species (67%) are included in global and regional Red Lists. Twenty-five species (24.2%) are within the categories Critically Endangered (CR), Endangered (EN), Vulnerable (VU) and Near-Threathened (NT). The network of Marine Protected Areas in Southeastern Brazil is still incipient, and the considerable number of threatened species in the Anchieta Island State Park clearly indicates the importance of the study area for the conservation of coastal and reef fishes.Key words: rocky reefs; species richness; scientific diving; ichthyology; conservation. Peixes recifais do Parque Estadual da Ilha Anchieta, Sudoeste do Atlântico, BrasilResumo: Este artigo apresenta uma lista de espécies de peixes recifais do Parque Estadual da Ilha Anchieta, uma área na qual nenhuma atividade extrativista é permitida, em Ubatuba, Sudeste do Brasil. Os dados foram coletados entre 2011 e 2013, principalmente por observações subaquáticas com o uso de mergulhos livres e autônomos e, secundariamente, através de pescaria científica (arrasto). Dados publicados e não publicados também foram verificados e compilados. Foram registradas 103 espécies de peixes recifais distribuídas em 78 gêneros e 50 famílias. Haemulidae foi a família com maior número de espécies (n=7 espécies), seguida por Epinephelidae (n=6), Pomacentridae, Carangidae e Tetraodontidae (n=4 cada). Os gêneros com maior número de espécies foram Haemulon (n=5) e Stegastes¸ Acanthurus e Mycteroperca (n=3 cada). Sessenta e nove espécies (67%) estão inclusas em listas vermelhas de espécies ameaçadas globais e regionais. Vinte e cinco espécies (24,2%) são classificadas nas categorias Criticamente em Perigo (CR), Em Perigo (EN), Vulnerável (VU) e Quase Ameaçadas (NT). A rede de Áreas Marinhas Protegidas no Sudeste do Brasil ainda é incipiente e o considerável número de espécies ameaçadas no Parque Estadual da Ilha Anchieta indica claramente a importância da área de estudo para a conservação de peixes recifais e costeiros.
