Are Abrolhos no-take area sites of naïve fish? An evaluation using flight initiation distance of labrids Neotropical Ichthyology
Nunes,José de Anchieta C. C.; Loiola,Miguel; Miranda,Ricardo J.; Sampaio,Cláudio L. S.; Barros,Francisco.
ABSTRACT 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...

Acyrtus pauciradiatus, a new species of clingfish (Teleostei: Gobiesocidae) from Fernando de Noronha Archipelago, Pernambuco state, Northeastern Brazil Neotropical Ichthyology
Sampaio,Cláudio L. S.; Nunes,José de Anchieta C. C.; Mendes,Liana F..
Acyrtus pauciradiatus, new species, is described on the basis of three specimens collected at Fernando de Noronha Archipelago, state of Pernambuco, Brazil. It differs from its congeners by having a reduced number of rays in the pectoral, dorsal, and anal fins and is more isolated geographically, than any other species in the genus.

Flight response of the barber surgeonfish, Acanthurus bahianus Castelnau, 1855 (Teleostei: Acanthuridae), to spearfisher presence Neotropical Ichthyology
Benevides,Larissa J.; Nunes,José de Anchieta C. C.; Costa,Tiego L. A.; Sampaio,Cláudio L. S..
ABSTRACT When confronted by predators, prey need to make an economic decision between continuing their current activity or flee. Flight Initiation Distance (FID), the distance at which an organism begins to flee an approaching threat, has been used to indicate an animal's fearfulness level and a way to examine factors influencing escape decisions. Here we investigated how the FID of the barber surgeonfish, Acanthurus bahianus, responds to the presence of spearfishers in a fishing site in northeast Brazil. Specifically, we examined whether the FID was influenced by body and group size; by the heterogeneity of species in groups formation; and the distance to shelter. Significant differences in FID were observed with increasing body size. We found no...

Collaborative monitoring of the ornamental trade of seahorses and pipefishes (Teleostei: Syngnathidae) in Brazil: Bahia State as a case study Neotropical Ichthyology
Rosa,Ierecê L.; Sampaio,Cláudio L. S.; Barros,Adrianne T..
Many species of seahorses and pipefishes (family Syngnathidae) are traded for medicinal purposes and aquaria; some are also sold as souvenirs or curiosities. Brazil is one of the main suppliers of seahorses for the international aquarium trade, nevertheless, little is known about the magnitude of that trade in the country. With regards to pipefishes, virtually nothing is known about their captures for ornamental purposes in Brazil. The present study assesses the magnitude of captures and trade of seahorses and pipefishes, based on data obtained through a collaborative monitoring program established with the main retailer of marine ornamental organisms in the State of Bahia. The syngnathid fishery is conducted in shallow waters never exceeding 7 m,...

The effects of fish feeding by visitors on reef fish in a Marine Protected Area open to tourism Biota Neotropica
Paula,Yuri Cruz de; Schiavetti,Alexandre; Sampaio,Cláudio L. S.; Calderon,Emiliano.
Abstract: Coral reef-based tourism has risen sharply across the globe, coupled with an increase in fish feeding by visitors. Studies indicate that fish feeding is one of the leading causes of changes in distribution patterns, abundance, the structure of marine fish communities, and fish behavior. The aim of this study was to determine the effect of human presence and fish feeding on the behavior of reef fish by conducting in situ experiments in tide pools in a Marine Protected Area located at the northern limit of the Abrolhos Bank in the South Atlantic Ocean. Eight feeding sessions were conducted and filmed, resulting in a total of 160 minutes of video footage. Each filming session recorded four different experimental conditions alternating between human...
