Abstract	The enzyme carbonic anhydrase (CA) has well-known functions in acid-base balance, respiratory gas exchange, and osmoregulation in teleost fishes. However, studies concerning the role of CA in elasmobranchs are still scarce. Therefore, the aim of this study is to present the current status of CA studies in sharks and rays, as well as to identify gaps and emerging needs, in order to guide future studies. This review is organized according to the main roles of CA, with further considerations on climate change and CA effects indicated as paramount, as strategies in the face of climate change can be crucial for species response. The literature review revealed a reduction in publications on CA over the years. In addition, a historical research differentiation is noted, where the first assessments on the subject addressed investigations on basic CA functions, while the most recent studies present a comparative approach among species as well as interdisciplinary discussions, such as ecology and phylogeny. Considering that several elasmobranchs are threatened, future studies should prioritize non-lethal methodologies, in addition to expanding studies to climate change effects on CA.

Abstract	Cambeva melanoptera sp. nov. is described from stream tributaries of the Rio Iratim, Rio Iguaçu drainage, southern Brazil. This new species is remarkable with a colour pattern not found elsewhere among trichomycterid catfishes, consisting of a broad distal black zone in all unpaired and pectoral fins, strongly contrasting with a pale‐yellow proximal zone. C. melanoptera also differs from all other trichomycterids from eastern South America by the presence of the nasal barbel about thrice longer than the maxillary and rictal barbels. Due to the presence of a similar bicolour caudal fin, the new species is tentatively considered closely related to Cambeva castroi and Cambeva diabola, as well as more closely related to C. castroi than to C. diabola, with the first two species sharing the presence of a curved lateral process of the parurohyal and a trapezoidal projection on the lateral margin of the lateral ethmoid. The great morphological diversity found in Cambeva species endemic to the Rio Iguaçu drainage, including numerous exclusive characteristics not occurring in congeners and in any other species of closely related trichomycterine genera, indicates the need for more studies focusing on possible causal factors responsible for such unique diversification pattern.

Abstract	Brazil is currently facing one of the worst environmental crises in history. The over-exploitation of natural resources, unrestrained expansion of fisheries, and mostly ineffective conservation policies impose great difficulty in regulating and supervising fishing activities, whether commercial or recreational. Unreported and unregulated recreational fisheries are largely carried out along the Brazilian coast; however, their potential for exploitation of fish stocks remain unknown. To obtain data regarding this popular and poorly known leisure activity, we compiled information on catches posted by recreational anglers on a social media platform between 2008 and 2013. Photographic records of fish caught on the continental shelf off the southern Atlantic Ocean in Brazil were downloaded and assessed, and species were identified and quantified (trophies and total captures) for each fishing trip (day), including the number of anglers, totaling 788 fishing days, with an average of 4.2 anglers/day. A total of 50 species were recorded: eight elasmobranchs and 42 teleosteans. Regarding conservation status, 25 species were categorized as threatened (25.5%) and one as data deficient (25.5%) at the global level according to the International Union for Conservation of Nature. Notably, elasmobranchs, dolphinfishes, bluefishes, croakers, triggerfishes, Atlantic bigeyes, and sharks showed high capture frequencies. Our results indicate the need for an efficient system to monitor recreational fishing, as well as co-management plans discussed with all stakeholders to control and reduce the worrying rate of capture of threatened species.

Abstract	The reproductive biology of Centropomus parallelus was described from 589 individuals captured in estuarine and coastal waters in Southern Brazil. Length‐frequency distribution showed the dominance of males in smaller length‐classes (132–290 mm LT), whereas females were dominant in larger length‐classes (>290 mm LT). Total length at maturity (L₅₀) was 180 mm LT and corresponded to 29% of the maximum length recorded. Histological sections revealed one hermaphrodite (205 mm LT) and few immature females. Life history traits provided herein can contribute to sustainable fisheries management practices.

Abstract	A recent field inventory focusing on catfishes of the trichomycterine genus Cambeva detected the occurrence of two morphotypes, C. barbosae and C. cubataonis, in the Guaratuba-Babitonga-Itapocu area (GBIA) of southern Brazil, reporting some discordance with results of coalescent-based approaches for species delimitation that indicated different estimates of species number. Contrastingly, based on examination of characters taken from the external morphology and osteology, we here recognised six species of Cambeva in GBIA: C. cf. botuvera, a polymorphic and geographically widespread species; C. cubataonis, endemic to the Rio Cubatão do Norte; and four new species, two endemic to the Rio Itapocu basin, one endemic to the Baía de Babitonga system and one endemic to the Baía de Guaratuba system. We performed a molecular phylogenetic analysis indicating that Cambeva comprises three major clades, the alpha-, beta- and gama-clades, with C. cf. botuvera and a clade comprising C. cubataonis and three new species belonging to the beta-clade and another new species belonging to the gama-clade. We concluded that species here recognised are not in fact incongruent with results of that recent study when taxa are correctly identified by a representative sample of morphological characters, highlighting the importance of osteological characters for delimiting trichomycterine species.

Abstract	Identifying fish spawning aggregations is crucial to determine effective fisheries management measures and protect key reproduction sites. We found direct evidence (the presence of post-ovulatory follicles) of a spawning aggregation of cubera snapper (Lutjanus cyanopterus) within the largest multiple-use marine protected area in southeastern Brazil, representing the first in-situ validation of a cubera snapper spawning aggregation in subtropical waters off the southwestern Atlantic. Out of 127 specimens (weighing ~ 2253 kg total) illegally caught by a fishing vessel on January 17th, 2021, fourteen individuals, ranging from 82 to 115.4 cm, were randomly selected and analyzed. The histological examination of six ovaries showed spawning-capable individuals and multiple spawning patterns. This cubera snapper spawning aggregation event probably relates to increased temperatures in the summer months, and the complexity of habitats and geomorphological formations in the region. Even though the species has high economic value in the region, targeted by both commercial and recreational fishing, Brazilian legislation imposes capture restrictions that ignore scientific evidence and are limited to the winter months, a season lacking aggregation reports. Our findings highlight the need for a comprehensive management strategy that includes seasonal fishing closures and monitoring and research collaborative programs.

Abstract	The billions of tons of plastic released into the environment mostly fragment into smaller particles that reach rivers and oceans, posing toxicity risks to aquatic organisms. As fish serve as excellent environmental indicator organisms, this study aims to comprehensively review and quantify published data regarding the abundance of microplastics (MPs) ingested by fish through scientometric analysis. Systematic analysis reveals that global aquatic ecosystems are contaminated by MPs, with the characteristics of these contaminants stemming from inadequate disposal management practices. The abundance of MPs was recorded in several fish species, notably Cyprinus carpio in natural environments and Danio rerio in controlled environments. According to the surveyed studies, laboratory experiments do not accurately represent the conditions found in natural environments. The results suggest that, in natural environments, the predominant colors of MPs are blue, black, and red. Fibers emerged as the most prevalent type, with polyethylene (PE) and polypropylene (PP) being the most frequently identified chemical compositions. On the other hand, laboratory studies showed that the spheres and fragments ingested were predominantly polystyrene (PS) green, followed by the colors blue and red. This discrepancy complicates drawing accurate conclusions regarding the actual effects of plastic particles on aquatic biota. Given the enduring presence of plastic in the environment, it is imperative to consider and implement environmental monitoring for effective, long-term management.
