ABSTRACTThe relationships between meiofaunal communities and hard substrate are relatively well‐documented in the scientific literature. However, a comprehensive quantitative review of global research on meiofauna colonization across different hard substrates has not yet been conducted. In this study, a scientometric analysis was performed to evaluate scientific interest in various hard substrates in studies exploring the influence of spatial heterogeneity on meiofaunal colonization. A total of 124 articles published from 1967 to 2023 were selected from online databases. Macroalgae were the most frequently studied hard substrate, and it was the one that harbors the highest abundance and richness values compared to other substrates. Studies predominantly focused on specific taxonomic groups, particularly Copepoda, Harpacticoida, and Ostracoda. Nematoda, Copepoda, Harpacticoida, and Amphipoda were the most commonly recorded meiofaunal taxa. Geographically, the United States of America was the most productive country in this field, followed by Brazil. Multivariate analyses, especially Non‐Metric Multidimensional Scaling (nMDS), were the primary quantitative methods used. A decline in studies on meiofauna‐substrate relationships over recent years was observed. Given the extensive research on macroalgal colonization, future studies should consider a wider variety of hard substrates to expand understanding in this field.

Abstract The barred grunt, Conodon nobilis (Linnaeus, 1758), is one of the most important marine-estuarine fish along the Brazilian coast. The present study evaluated the parasite fauna of this haemulid fish along the Southern Atlantic coast. From September 2010 to July 2011, a total of 100 specimens of C. nobilis from Angra dos Reis, Rio de Janeiro State, Brazil (23°01′21ʺS, 44°19′13ʺW), were examined. Ninety-seven individuals were parasitized by at least one species of metazoan, with a mean of 4.50 ± 3.54 parasites per fish. Eighteen species of parasites were collected: eight copepods, four digeneans, two cestodes, one acanthocephalan, one aspidogastrean, one isopod and one monogenean. The copepod Lernanthropus rathbuni was the most abundant and dominant species, accounting for 17.77% of all parasite specimens collected. Caligus haemulonis was the most prevalent. Prevalence and abundance of Acantholochus lamellatus and L. rathbuni tended to be higher in smaller fish, whereas those of Torticaecum sp. were higher in larger fish. The mean abundance of C. haemulonis was significantly higher in male hosts. A negative association was observed between two species of ectoparasites. The parasite community of C. nobilis was characterized by dominance of copepods, which can be related to host’s schooling behavior.

This study presents the first record of T. lindbergi from the southwestern Atlantic Ocean, based on specimens collected from the smalleye croaker Nebris microps Cuvier (Sciaenidae), off the coast of Maranhão Island, State of Maranhão, Brazil. Our approach included a morphological analysis complemented by DNA sequencing (28S, ITS2 rDNA, and cox1 mtDNA). Our phylogenetic analysis revealed the affinity of T. lindbergi to its congener T. laticaudi Parukhin, 1969, a digenean parasite commonly found in hydrophiine snakes inhabiting the Pacific Ocean. The interspecific divergence between T. lindbergi and T. laticaudi measures 3.80% for 28S, 7.49–7.64% for ITS2, and 16.29–16.70% for cox1. Our findings expand the documented geographic range of T. lindbergi into the southwestern Atlantic Ocean, report a novel host record, and increase the number of hemiurids known from Brazil to 30 species. Additionally, this study represents the initial documentation of a marine digenean fish within the North Brazil Shelf.

Abstract Ergasilid copepods represent one of the commonest groups of fish parasites in Brazil. Within Ergasilidae, three genera share a peculiar latching mechanism on the antenna that completely encircles the gill filament, one of which is Acusicola Cressey, 1970. During a survey of estuarine fish from the Brazilian Amazon Coast, a new species of Acusicola was found on the gills of the largescale foureyes Anableps anableps (Linnaeus, 1758) (Actinopterygii: Anablepidae) in São Marcos Bay, State of Maranhão. Acusicola rochai n. sp. can be distinguished from its closest congeners mainly by three protrusions on the dorsal surface of third and fourth pedigerous somites, and by smooth interpodal plates. This work is the first report of a parasitic copepod infesting a fish from Anablepidae and, consequently, the host An. anableps. The existing dichotomous key proposed for the genus Acusicola includes only ten species, excluding the eight species subsequently described. Therefore, in the present work, a new dichotomous key is provided based on reliable and well-documented features.

Abstract Mobulid rays are medium‐ to large‐sized pelagic‐dwelling planktivorous elasmobranchs that are circumglobally distributed. Brazil has a high diversity of Mobula species, with five of the nine globally valid species and one additional putative new species. Brazil represents a substantial knowledge gap concerning the ecology, distribution and threats to mobulid rays. In global distribution analyses, several species have been underrepresented along the Brazilian coast. The dataset is composed of information from peer‐reviewed and grey literature, as well as data from scientific expeditions, citizen science collaboration, social media and local news. We found 6,450 records of manta and devil rays along the Brazilian coast, including Mobula tarapacana, Mobula mobular, Mobula thurstoni, Mobula hypostoma, Mobula birostris and the putative new species (Mobula cf. birostris). Our results revealed alarmingly high captures, such as 4.5 tons of M. hypostoma in a single fishery cruise and 809 individuals of Mobula spp. from a single fleet during one year in the Southeastern region. These findings evidence the fisheries' threats to mobulid species in Brazil and highlight previously unnoted species records, such as the occurrence of M. hypostoma on the entire Brazilian continental shelf, including estuaries and M. tarapacana in coastal regions. Integrative information on the occurrence, distribution, and threats to mobulid rays on local and global scales is crucial to supporting strategies for their effective management and conservation.

AbstractLittle is known about the ecology and distribution of mobulid rays along Brazil's extensive coastline. Here we report opportunistic sightings of manta rays (Mobula cf. birostris) in the Brazilian Amazon estuaries and the Great Amazon Reef System. These sightings consist of manta ray individuals stranded in tide pools, caught in artisanal fisheries, and footage obtained with a submersible. Future investigations on the spatial, temporal, and environmental drivers of manta rays' distribution on the northern Brazilian coast and the threats posed by fishing gear are warranted.

Despite ongoing research efforts, the ichthyofauna of the coastal basins of Maranhão State, Brazil remains poorly described (Abreu et al., 2019). In recent years the number of research publications on fish diversity in this region has increased (e. g. Brito et al., 2019; Guimarães et al., 2020; Oliveira et al., 2020), however important work remains to be done. An accurate assessment of population parameters related to fish reproduction is an essential component of effective fisheries management (Brown‐Peterson et al., 2011; Nascimento et al., 2015; Nunes et al., 2019). The Baixada Maranhense Environmental Protection Area is a RAMSAR site consisting of a complex ecosystem in which human beings play an essential role in managing, using, and conserving several components. Due to the abundance of regional water resources, fishing is among the most important socioeconomic activities (Araujo and Pinheiro, 2008). In recent decades this region has undergone substantial anthropogenic changes, decreased river water flow, siltation, damming, and other anthropic activities compounded by changes in rainfall patterns (Cantanhêde et al., 2017). Monitoring the ichthyofauna in rivers is essential to identify environmental responses to human actions and provides subsidies to regulate the use of water resources, thus enabling the development of alternatives to minimize river degradation (Santos et al., 2017; Lima et al., 2018). This study describes the minimum size at first maturation (L50) of commercially important fish species in two distinct habitats (a river and a lake) within the Pindaré River Hydrographic Basin. We use data from monthly collections that were carried out for 18 months (January 2015 to June 2016), in Lake Viana and the Pindaré river in the state of Maranhão, in northeastern Brazil. The study area is a designated RAMSAR Site, protected by Brazil under the RAMSAR intergovernmental treaty (Brasil, 2010). It is characterized by seasonal changes in rainfall that influence both the reproductive behavior and adaptations of fish species and the dynamics of the local fishing industry. When there is a shortage of fish stocks, extractive activity is intensified to meet demand, and the seasonal reduction in floods that occur annually triggers annual overfishing (Carvalho et al., 2017; Carvalho et al., 2021). We purchased specimens used for this work from local fish markets, then stored them on ice for transport to the laboratory, where they were subsequently identified to the lowest possible taxonomic level. We then analyzed all specimens morphologically to assess total length (TL) and total weight (TW) with the aid of an ichthyometer and an electronic caliper with a precision of 1 mm and 0.01 g, respectively. Then we made a longitudinal incision on the ventral portion of each specimen to remove the gonads. We then fixed the gonads in a 5% formalin solution for subsequent preservation in 70% ethanol. We deposited all specimens in the Collection of tissues and DNA of the fauna of Maranhão, UEMA (CoFauMA), and in the teaching collection of fishes of the Laboratory of Fisheries and Aquatic Ecology, UEMA (LabPEA). We assessed the reproductive state for each specimen through macroscopic identification of the stage of gonadal maturation and characterization of the gonads according to the scale proposed by Brown‐Peterson et al. (2011) and Lowerre-Barbieri et al. (2011). We calculated minimum size at first maturation (L50) based on the cumulative curve of occurrence frequencies of adult individuals by total length class adjusted to the logistic function. We characterized the maturation as A (immature); B (under development); C (able to spawn); D (regressing), and E (regenerated). We calculated the percentage of adult organisms (stages B, C, D, and E) by length class and considered as a dependent variable (Y) and the total length as an independent variable (X). Subsequently, we fitted these values to a logistic curve, using the Statistica 7 Program according to the following formula: P = 1/(1+exp[-r (L – Lm)]). P is the proportion Length at first sexual maturity of the freshwater fish fauna of the Baixada Maranhense Environmental Protection Area

Abstract Sharks of the genus Sphyrna are under intense exploitation globally. In Brazil’s northern coast, this genus represents a high proportion of fisheries landings and comprises four species. However, due to difficulty of specific identification when specimens are landed, most of the records are limited to the genus level. Here we analyzed the effectiveness of ITS2 (Internal Transcribed Spacer 2 of rDNA) fragment length protocol (Abercrombie et al., 2005) for identifying hammerhead shark species, comparing with the analysis of COI (Cytochrome oxidase subunit I) and ITS2 sequences. We evaluated samples of muscle tissue acquired in the main fishing ports of Maranhão: Carutapera, Raposa e Tutóia. Sampling was conducted between March 2017 to March 2018 and complemented with material deposited in collection (2015). COI results indicated the occurrence of endangered species which are prohibited to be landed. These include Sphyrna mokarran (67%), S. lewini (15%), S. tudes (3%), and S. tiburo (15%). For the ITS2 marker, we investigated the optimization of the protocol developed by Abercrombie (2005) for to improve the use in this geographical area througout design of a new primers.

Abstract. This study examines the risks associated with relying solely on images for documenting new species records, rediscoveries, taxonomic descriptions, and distribution expansions. We highlight concerns regarding image authenticity, especially in cases where images may be altered, adulterated, or AI (artificial intelligence)-generated, potentially leading to inaccuracies in biodiversity documentation. To illustrate the evolving challenges, we conducted an experiment with 621 participants who assessed nine AI-generated images. Surprisingly, six were deemed authentic, while three raised doubts, highlighting the difficulty in discerning AI-generated content. Our main message emphasizes the critical role of trust in biodiversity documentation, particularly for taxonomy and conservation, and how eroded trust can hinder conservation efforts. Improved communication and collaboration between taxonomists and conservationists are needed, emphasizing scientific integrity. We urge a reevaluation of journal policies concerning data validation, especially in articles relying on images as primary evidence, to preserve the credibility of scientific research amidst technological advancements.

AbstractFish mislabeling is a global issue with far‐reaching consequences for both food security and biodiversity conservation. This practice involves the intentional or unintentional misidentification of fish species sold in markets and restaurants, often driven by economic gain or cultural preferences. The mislabeling of threatened fish species further exacerbates the problem. This manuscript focuses on an emerging mislabeling practice in the Brazilian Amazon coast, which impacts a critically endangered elasmobranch species, the Daggernose Shark Isogomphodon oxyrhynchus. More specifically, the mislabeling of the Atlantic Tripletail Lobotes surinamensis as the Acoupa Weakfish Cynoscion acoupa has led to intensified fishing activities and incidental capture of the Daggernose Shark. Traditional enforcement approaches have shown limited effectiveness, and alternative conservation interventions, including participatory management and education programs for artisanal fishers, are needed to address this complex issue.

IntroductionThe current Isogomphodon oxyrhynchus (Daggernose Shark) population status Q7points to 99% losses in the last decade due to certain biological traits, site fidelity, and historical high representativeness as bycatch in artisanal fisheries. This species is listed as Critically Endangered (CR), both in the IUCN and the Brazilian Red Lists. Its vulnerability is so high that its recovery potential requires protection from ongoing fishing pressure.ObjectiveIn this context, this study aimed to evaluate the health status of Daggernose sharks and their ability to cope with allostatic overload in a comparative analysis with other Carcharhinid and Sphyrnid sharks.MethodsSharks incidentally caught by the artisanal fleet in the state of Maranhão, on the Brazilian Amazon Coast, were sampled for blood, and serum was used to assess biochemical markers.ResultsThe findings indicate significant differences in Daggernose Shark homeostatic capacity for ALP, ALT/GTP, creatinine, lactate, urea, total cholesterol, and triglycerides, pointing to lower health scores and recovery capacity when compared to other Carcharhiniformes inhabiting the same region.Discussion and conclusionsIt is possible that such vulnerability is a result of fisheries-induced evolution, leading to remaining populations with very low chances of fully recovering. Conservation planning is thus urgent, as current legislation based on fishing bans does very little for the species. International collaboration and longterm recovery measures are necessary, including the creation of MPAs specially designed for the species and captive maintenance aiming to monitor health status and carry out breeding attempts.
