“…3) of U. cordatus collected in the study areas, a significant difference was observed in the frequency of alterations, with the port area presenting the higher alterations in crabs. These data corroborate with the results observed for gill alterations in the same crabs analyzed in the port region (Carvalho-Neta et al, 2019;Oliveira et al, 2019). Therefore, it is inferred that the alterations observed in different organs of crabs from the port area are due to chronic chemical contamination in the environment.…”

“…Carvalho-Neta et al (2012) and Oliveira et al (2019) analyzing the sediment in the study area identified high levels of heavy metals. Also, Sousa et al (2013) using biomarkers in catfish, Oliveira et al (2019) and Carvalho-Neta et al (2019), using biomarkers in crabs collected in São Marcos' Bay, identified significant histopathological responses in the gills of these organisms. These data suggest that the port area in São Marcos' Bay, which is an important habitat for crabs, is being influenced by the impacts caused by the port activities in that region.…”

“…In the literature, there are several reports on the histopathological effects of pollutants on crustacean gills (Bhavan & Geraldine, 2000;Arockia-Vasanthi et al, 2014;Maharajan et al, 2015;Negro, 2015). However, are still few studies about the effects of pollutants in U. cordatus, especially in the state of Maranhão (Carvalho-Neta et al, 2019;Oliveira et al, 2019). Thus, detailed biomonitoring studies in the port areas are extremely necessary, especially about the specific role of each type of crab gill.…”

“…The histological analysis of gills and hepatopancreas of crustaceans has been increasingly recognized as a valuable tool for the evaluation of the impacts of pollutants on crustaceans (De Freitas-Rebelo et al, 2000;Maharajan et al, 2015;Negro, 2015;Carvalho-Neta et al, 2019). The gills are characterized as the first organ to get in contact with environmental pollution; this organ is highly sensitive to chemicals (Negro, 2015), which can lead to severe problems for the organism.…”

“…Crustaceans easily accumulate pollutants present in the aquatic environment, as well as through biomagnification by the trophic chain, representing an important route of contamination to public health (Pinheiro et al, 2013). Thus, these organisms present high sensitivity to the xenobiotics available in the environment (Carvalho-Neta et al, 2019;Oliveira et al, 2019).…”

This study aimed to identify alterations in gills and hepatopancreas of the crab Ucides cordatus as indicative of environmental contamination in mangrove areas subject to chemical effluents from port activities in Maranhão, Brazil. Samples of gills and hepatopancreas were removed from each animal and fixed in Davidson's solution until the procedure of histological technique. The biometric data (means and standard deviations) of the specimens collected in the study areas indicated that the crabs in the reference area are significantly (P < 0.05) higher and heavier than the crabs collected in the potentially impacted area (port area). Gill alterations (rupture of pilaster cells, dilation of the marginal channel, cuticle rupture and necrosis) and hepatopancreas alterations (abnormal lumen, vacuolized B cells, pycnotic nuclei and necrosis) were significantly (gbn < 0.05) more frequent in crabs collected in the port area than crabs collected in the reference area. These data indicate that the health of crabs is compromised due to the pollutants present in the mangroves that surround the port area in São Marcos’ Bay.

Oil spills pose a significant threat to marine biodiversity. Crude oil can partition into sediments where it may be persistent, placing benthic species such as decapods at particular risk of exposure. Transcriptomic and histological tools are often used to investigate the effects of hydrocarbon exposure on marine organisms following oil spill events, allowing for the identification of metabolic pathways impacted by oil exposure. However, there is limited information available for decapod crustaceans, many of which carry significant economic value. In the present study, we assess the sublethal impacts of crude oil exposure in the commercially important Australian greentail prawn (Metapenaeus bennettae) using transcriptomic and histological analyses. Prawns exposed to light, unweathered crude oil "spiked" sediments for 90 h were transferred to clean sediments for a further 72 h to assess recovery. Chemical analyses indicated that polycyclic aromatic hydrocarbons increased by approximately 65% and 91% in prawn muscle following 24 and 90 h of exposure, respectively, and significantly decreased during 24-and 72-h recovery periods. Transcriptomic responses followed an exposure and recovery pattern with innate immunity and nutrient metabolism transcripts significantly lowered in abundance after 24 h of exposure and were higher in abundance after 72 h of recovery. In addition, transcription/translation, cellular responses, and DNA repair pathways were significantly impacted after 24 h of exposure and recovered after 72 h of recovery. However, histological alterations such as tubule atrophy indicated an increase in severity after 24 and 72 h of recovery. The present study provides new insights into the sublethal impacts of crude oil exposure in greentail prawns and identifies molecular pathways altered by exposure. We expect these findings to inform future management associated with oil extraction activity and spills.

Accumulation of pollutants in the aquatic system has a high impact on the reproductive physiology of crustaceans. The objective of the present study was to assess the possible histopathological effects of combined chlorpyrifos and cypermethrin (nurocombi) exposure on reproductive tissue in male freshwater crab Paratelphusa jacquemontii using light and electron microscopy. The testis of experimental crabs showed disorganization of testicular lobules, increased inters cellular space, necrosis, and cellular damage in both germinal cells and Sertoli cells. The treated vas deferens exhibited epithelial degeneration, misshaped spermatophores, decline in the number of spermatophores, and dehiscence of spermatophore wall. These clinical manifestations expressed in crabs following the exposure of nurocombi significantly reduce the testicular activity and substantially inhibits the seminal secretions, which ultimately lead to impairment of reproduction.
