“…However, spatial and temporal assemblage patterns were not evaluated. Despite the dominance of a few species, which is a remarkable feature in lagoon and estuarine environments due to significant changes in physical and chemical variables (Day et al, 1989), there are differences in abundance between seasons and areas, commonly present in other surveys conducted in shallow areas (Spach et al, 2010;Contente et al, 2011;Vilar et al, 2011;Souza-Conceição et al, 2013;Cartagena et al, 2014;Ribeiro et al, 2014;Soeth et al, 2015;Cattani et al, 2016a). The use of such environments by juveniles, generally zoobenthivorous, is characterized by the availability of food associated with the substrate.…”

A large number of fish species use the mangrove mainly due to food availability and protection against predators. The knowledge of temporal and spatial dynamics of ichthyofauna allows us to identify patterns of occupation of this ecosystem and to support the assessment and preservation of local biodiversity. In this sense, samplings were conducted in 1988 at five areas of the Itacorubi River estuary, Santa Catarina Island. A total of 3,883 specimens were collected, distributed in 21 families and 41 species with the predominance of Cetengraulis edentulus, Mugil liza, Mugil curema, Genidens genidens, Mugil gaimardianus, Eucinostomus gula, Micropogonias furnieri, Pomatomus saltatrix and Sphoeroides testudineus. On average, abundances differed between seasons and sampled areas. Differences were detected between the fish faunas of fall and winter compared to summer and spring and between sampling sites. This study identified a fish assemblage in the mangrove of the Itacorubi River with a similar structure to other estuaries of southern Brazil.

“…Despite the great variety of ecosystems, knowledge about fish assembly from the Island of Santa Catarina is scarce. Only a few studies have been conducted, which focused on spatio-temporal patterns in specific environments (Clezar et al 1997, Ribeiro et al 1997, Ribeiro et al 1999, Cartagena et al 2011, Soeth 2015. Therefore, this study aimed to present a checklist of marine fishes from different coastal environments of the Island of Santa Catarina through a compilation of unpublished and published information from the literature.…”

This study aimed to present a checklist of marine fishes from coastal environments of the Island of Santa Catarina, including comments on the zoogeographic affinities, conservation status of each species, and functional groups. A total of 169 fish species belonging to 30 orders and 58 families were recorded. The most speciose families were Sciaenidae, Carangidae and, Engraulidae, representing 26,62% of the recorded species. Anchoa was the richest genus, followed by Sphoeroides and Cynoscion. Most of the species have their distribution limited to the western Atlantic, and two groups of fish were distinguished according to the species distributions: 1) species occurring in the Caribbean and in the Brazilian Province; and 2) Transatlantic species. Thirteen species are critically threatened, 10 are overexploited on the Brazilian coast, and 2 are threatened by extinction. Most of the species are either marine stragglers or marine migrants, and most of them are zoobenthivores, piscivores, or both.

“…In order to minimize the bycatch in shrimp fisheries, many researchers have been suggesting the development of bycatch reduction devices (BRD) as an alternative to fisheries management (Andrew et al 1993, Broadhurst and Kennelly 1996, Broadhurst 2000. The overwhelming majority of published records was devoted to BRDs in shrimp trawls and only few efforts were intended to reduce bycatch in other shrimp fisheries (Larocque et al 2012, Colotelo et al 2013, Soeth et al 2015. It has been widely known that shrimp fyke nets catch an excessive number of different bony fishes that usually are discarded after the fishing activity but only few authors suggested low-cost alternatives to reduce this problem (Vianna andD'Incao 2006, Soeth et al 2015).…”

Domingos M.M., Dantas D.V. 2019. Proposed bycatch-reduction modifications of shrimp fyke nets used in South American lagoons. Acta Ichthyol. Piscat. 49 (1): 1-7.Background. Shrimp fisheries using fyke nets have been associated with a massive acquisition of teleost fishes as bycatch, potentially resulting in the decimation of their stocks. Based on this assumption, the presently reported study intended to test an alternative modification of a commonly used fyke net, in order to minimize the impact of its low selectivity. Materials and methods. To evaluate the alternative design proposed in this work, a total of 44 sampling efforts, including 22 with a control gear (CG) and 22 with a modified gear (MG), were conducted at a subtropical coastal lagoon system located in southern Brazil. In all trials, the fyke nets were installed at the fishing area approximately at 18:00 h and removed approximately at 06:00 h. The duration of each trial was nearly 12 h, which was similar to the catching time preferred by local fishermen. Results. Bycatch (BC) was preponderant in both modalities but the results showed that MG presented a reduction by 66 percentage points in BC catches, being more selective than CG. Additionally, the non-parametric test showed no significant differences of shrimp catches between the fishing gears used (MG and CG). So, the tested bycatch reduction devices (BRD) reduced the bony fishes acquisition preserving the volume of the target catch. Conclusion. The vertical opening reduction due the adoption of guiding panel + fan upper panel contributed to bycatch reduction, being a consistent BRD to reduce the potential impacts of this fishing gear over the bony fishes stocks.
