A região Amazônica possui uma das maiores biodiversidades do mundo, contudo, a fauna e flora estão cada vez mais sendo impactadas por ações humanas, especialmente atreladas a introdução de espécies exóticas na região. O Camarões-arco-íris Mierspenaeopsis sculptilis (Heller, 1862) é nativo do Oceano Indo-Pacífico, porém já foi detectado como espécie exótica em várias regiões do mundo, causando danos ao ambiente e à biodiversidade nativa. Baseado nisso, este trabalho relata a nova observação do M. sculptilis para o município de Colares, Nordeste Paraense. Os indivíduos foram capturados em 20 novembro de 2024 com puçá de arrasto, na praia do Rio Novo – “Sonrisal”. Na pescaria foram capturados 20 exemplares, sendo 14 fêmeas e 6 machos, numa faixa de profundidade aproximada de 1,0 a 1,20 m. O registro de ocorrência de camarões-arco-íris jovens, nesta quantidade, indica que a espécie está completando parte do seu ciclo de vida nas águas salobras dos estuários do nordeste paraense, acendendo um alerta para a disseminação desta espécie exótica em áreas Amazônicas.

The occurrence of parasitism promoted by crustaceans in other groups is widely recorded in the literature, but the list of hosts and their impact on parasitized populations is still far from complete. Based on this, herein is reported the new occurrence of the copepod parasite Lernaeolophus striatus Wilson, 1913 from the State of Amapá, Northern Brazilian coast, reporting its new host, the snapper fish Lutjanus purpureus (Poey, 1866). The parasitised specimens of Lutjanus purpureus were collected in two points during commercial fishing operations in the Amazon continental shelf (03° 17’ 7.583” N, 49° 31’ 0.095” W, and 04° 09’ 14.190” N, 49° 47’ 59.831” W), covering regions associated with the Great Amazon Reef System (GARS), at a depth of 90 m, with a cage-like trap called “manzuá”. Four specimens (three males and one female) of Lutjanus purpureus were observed with Lernaeolophus striatus in the oral cavity, causing muscle degradation and necrosis in the upper portion of the head, observed as branches in the center of the cranium. The presence of parasite copepods in fish hosts, as the case of Lernaeolophus striatus, affects the central nervous system of the fish, degrading its orientation system and making the host more susceptible to predation.


Deformidade Congênita em Nadadeira Peitoral em Hypanus guttatus(Myliobatiformes: Dasyatidae)

This study aimed to document and describe the morphology of a non-fused pectoral fin to the head in a female H. guttatus(Myliobatiformes: Dasyatidae) captured from the Amazonian coast in Pará, Brazil. The observed anomaly is linked to mutations in the orbital cartilage, nasal capsule, propterygium and its segments, but the exact causes remain undetermined. Further detailed investigations of anomalous embryos, incorporating genetic and ecotoxicological data, are essential. Additionally, ongoing monitoring of such cases is crucial for a comprehensive understanding of the nature and prevalence of this abnormality.

Estuarine Coastal and Shelf Science

The Brazilian North Coast (BNC) encompasses the intersection of multiple oceanographic features such as strong currents, a large continental shelf under the influence of the Amazon River freshwater and sediment outflow, extensive muddy and sand bottom, as well as a mesophotic reef system. As a result, the BNC hosts a diverse fish fauna, consisting of estuarine and freshwater species, including species endemic to the region. These fish species are distributed across a mosaic of megahabitats within the region. Here, we present the first comprehensive effort to understand the distribution patterns of ray-finned fishes and cartilaginous fishes among these different megahabitats. On 1891 samples, we recorded 616 species from 147 families distributed across five distinct megahabitats. The Continental Slope megahabitat had the highest number of families and consisted primarily of pelagic species, indicating its close association with the open sea. The Sand and Mud megahabitats exhibited high species richness and shared similar generalist fish families in terms of habitat use. The Amazon Plume megahabitat was characterized by freshwater and marine euryhaline species, emphasizing the influence of the Amazon River on the BNC’s ecological dynamics. The Reef megahabitat had species closely associated with consolidated substrates and shared many species with the Sand megahabitat. This study offers valuable insights into fish species distribution and composition in the BNC, contributing to biodiversity assessments and conservation efforts in the region.

Revista CEPSUL - Biodiversidade e Conservação Marinha

We report the first confirmed record of the Graysby, Cephalopholis cruentata (Lacépède, 1802), from Brazilian waters, based on specimens collected at the Great Amazon Mesophotic Reef System (GAMRS), a complex environment with a consolidated bottom formed by living organisms. The new finding solves the discussion about the presence of the species in Brazilian waters and extends its distribution for about 400 km eastwards to the north coast of Brazil. Morphometric and meristic data of the specimens are provided and compared to literature. New data about the occurrence of the species in Venezuelan waters are also presented.

Case studies reporting crustaceans acting as basibionts for a wide range of encrusting invertebrates are widely observed in the literature. For swimming crabs of the genus Callinectes, these commensal interactions are commonly observed in estuaries and coastal zones worldwide. Despite the broad distribution of Callinectes bocourti A. Milne-Edwards, 1879 in Amazon province, the occurrence of epibiosis for this species in the area is rarely reported. Herein, we report the double occurrence of epibiont groups: the mollusks Ostrea puelchana d'Orbigny, 1842 and Sphenia fragilis (H. Adams & A. Adams, 1854) and the barnacles Amphibalanus improvisus (Darwin, 1854) and Chelonibia testudinaria (Linnaeus, 1758) from the new host C. bocourti, collected from the Amazon province, Brazil. The specimens of C. bocourti showing epibionts were collected manually in low tide, with a baited trap called "puçá", in the region of Curuçá River mouth, state of Pará (0°40'3,705"S, 047°54"43,405"W). We observed five specimens of C. bocourti showing double cases of epibiosis, composed by mollusks and crustaceans sharing the same area. In addition, here, we expand the range extension of the mollusk O. puelchana and we register the presence of the invasive species barnacle A. improvisus from the state of Pará, being this last species, reported as parasite adhered in carapace and branchial chambers of the host.

This study presents updated information on six exotic aquatic species (five crustaceans and one fish): Macrobrachium rosenbergii, Penaeus monodon, Charybdis hellerii, Balanus trigonus, Amphibalanus improvisus, and Pterois volitans. The research is based on bibliographic information available in scientific articles published by the Research Group Fishing and Evaluation of Tropical Fishery Resources and Biological and Photographic Records obtained from research projects conducted by CEPNOR/ICMBio. Currently, M. rosenbergii shrimp is classified as an invasive species, P. monodon is classified as a detected species, and C. hellerii is currently classified as an established species, but there are strong indications that it should be reclassified as invasive. The barnacles A. improvisus and B. trigonus have been classified as invasive, and lionfish P. volitans strongly exhibits advanced invasion process owing to its high frequency of capture in commercial fisheries.

In this paper, we report the northernmost Brazilian record of the red lionfish Pterois volitans (Linnaeus, 1758), highlighting the risk of bioinvasion of the species in French Guiana waters. The specimen of P. volitans was accidentally caught in June 2023, by artisanal multispecies fishery with gillnets in coastal waters in the region of Orange Cape, Oiapoque (State of Amapá) (04°43'00"N, 051°25'00"W), bordering French Guiana. The adult individual (~36 cm) was collected at a depth of 36.5 m, in a sandy-clay substrate in the continental shelf. The record of the species in the most extreme point of Brazil indicates a strong bioinvasion process of P. volitans in tropical waters; so, this work alerts the risk of the spread of the species to other countries of South America with its possible invasion in French Guiana waters.

The lionfish Pterois volitans (Linnaeus, 1758) is considered the most well-established fish species in non-native regions around the world, causing severe environmental damage and risks for the food chain. In Brazil, the lionfish was reported for the first time in 2014 in the State of Rio de Janeiro, and currently, the P. volitans was observed in more eight States, being its high level of occurrence in the Northern region, which contains an immense biodiversity that has not been totally cataloged yet. Based on that, this study aims to ratify the occupation and permanent residence of the lionfish in the Great Amazon Reef System (GARS), which is an alert for the urgent need for developing control strategies for this invasive species in Brazil. The new specimens were collected in the State of Amapá, between 2021 and 2022, during commercial lobster fishing, using the method of “Caçoeira”, covering between 70 and 100 meters of depth, while for the snapper was collected with the manzuá, between 78 and 102 meters of depth. In the laboratory, the individuals were measured in total length (TL) and total weight (TW). 21 specimens of P. volitans from the GARS, the TL ranged from 21,5 to 35,6 cm with an average of 29,43 cm, while the TW ranged from 150,0 to 733,0 g, with an average of 413,8 g. These adult specimens reinforce the stabilization of the lionfish, which have probably completed reproductive cycles in the region, requiring an urgent action by environmental agencies to control the invasion of the lionfish in Brazil, becoming a future environmental impact on native biodiversity.

... Estudos realizados por Pérez e Klippel (2006) e Cintra et al. (2023) indicam que as espécies exóticas podem ser consideradas uma forte ação de impactos ambientais, especialmente pela competição por recursos naturais, ampla dispersão e alta fecundidade, introduzindo alta abundância de novos organismos no ambiente. Adicionalmente a estes fatores, o transporte de microrganismos como vírus, bactérias e fungos, além de algas, protozoários e demais metazoários carreados no intestino, pele, pulmões e brânquias podem associar-se a uma invasão secundária de outros indivíduos. ...
