“…Dactylogyrus spp. are ectoparasites that occur naturally in southeast Asia 5,38 and their environmental stages (i.e., eggs and oncomiracidia) could be present in recirculating aquaculture systems, raceways, or ponds used to rear freshwater species by exporting companies. As such, it is possible that exporters could have used a water source contaminated with Dactylogyrus spp.…”

“…Imported consignments were considered ‘target’ or ‘non-target’ fish consignments based on published records of infection for any of the Dactylogyrus spp. targeted in this study ( n = 5) 5,24,25,33 . Based on this criteria, seven goldfish ( Carassius auratus (Linnaeus, 1758)) consignments were considered targets for D. anchoratus , D. formosus , D. intermedius , and D. vastator whereas four rosy barb ( Pethia conchonius (Hamilton, 1822)) consignments were considered targets for D. ostraviensis (Fig.…”

Effective border control relies on stringent biosecurity protocols to detect and prevent introductions of exotic pests and diseases. Detection of pathogens and parasites in the live ornamental fish trade using environmental DNA (eDNA) techniques has the potential to improve current biosecurity practices. We examined water samples from 11 target consignments (cyprinids susceptible to Dactylogyrus spp. infections) and seven non-target fish consignments (non-cyprinids, not susceptible to Dactylogyrus spp. infections) imported from Southeast Asia to Australia for the presence of eDNA from five Dactylogyrus species (Monogenea: Dactylogyridae). A four-step predictive framework was used to predict putative positive and putative negative detections from quantitative PCR assays. Both target and non-target consignments were positive for Dactylogyrus spp. eDNA as confirmed by Sanger sequencing. Positive detections for Dactylogyrus spp. eDNA in non-target fish consignments demonstrates the possibility of source water contamination, limiting the applicability of eDNA screening methods at border control. This study suggests that screening for parasite eDNA within ornamental fish consignments should be tested during pre-export quarantine periods to avoid false positive detections at border control. Lastly, the proposed predictive framework has a broad utility for minimizing false positive and false negative eDNA detections of aquatic organisms.

“…The final chapter in this eclectic volume by Alejandro Trujillo-González et al, addresses a much overlooked aspect in aquatic parasitology, the movement of ornamental fish stocks and with it the translocation of populations of parasite assemblages into previously non-endemic areas (Trujillo-González et al, 2018). A cornerstone fish species in the ornamental trade is the Goldfish (Carassius auratus).…”

Advances in Parasitology

View full text Add to dashboard Cite

Beginning in 1963, the founding rationale of Advances in Parasitology was to provide authentic, well-documented reviews by leading experts, about the progress being made in their area of specialism to inform the wider cadre of parasitologists, disseminating this information across allied disciplines and all users. Some 55 years later, the Series has accumulated over 667 published articles, with just over 650 authors contributing either alone or in collaboration, and has successfully served the parasitological needs of medical, veterinary and wildlife scientific communities with equity, notwithstanding treatises on vectors or intermediate hosts, as well as 'honorary parasites' such as viruses, bacteria and fungi. The first production of Advances in Parasitology united the publishing offices of Academic Press in the USA (New York) and the UK (London), maintaining Webster or Oxford writing styles, but unlike its production, all seven editors, beginning with Professor Ben Dawes, have been UK-based. While Advances in Parasitology is now published by Elsevier from their London Office, it still follows the tradition of hard backed book production, in either eclectic or thematic volume formats. But now, following academic imperatives, the Series supports online posting, allowing chapter(s) to be downloaded ahead of final production of the hard back volume. With the 100th volume of Advances in Parasitology, in eclectic format like the very first, there is good reason to celebrate and reflect on the academic impact and enduring legacy of this Series. Seen not only as a yardstick of publishing success but also as a testament, in part, to our fascination with parasites, these cursorily simple yet wonderfully complex organisms that often cause undue harm and much suffering, is still as vibrant, expanding and relevant as ever before.

“…Argulid identification can be difficult because of overlapping morphological characters, the ability of some freshwater and marine species to overlap in estuarine habitats, and many species are only known from their original descriptions [2,4,7]. The three best studied species in terms of their distribution, lifecycle, host use, and ecology are Argulus coregoni Thorell, 1865, Argulus foliaceus (Linnaeus, 1758), and Argulus japonicus Thiele, 1900 (reviewed in [6]), the latter of which has been introduced throughout the world [8]. Eighteen freshwater species of Argulus have been reported from North America [1] and 10 species have been reported from the Gulf of Mexico [9], with no species reported from the Pascagoula River, MS, USA.…”

Species of Argulus (Branchiura Thorell, 1864) are common ectoparasites of freshwater, estuarine, and marine fishes. Argulid identification and taxonomy is often confusing because many species are reported to parasitize multiple host species, have similar morphological characters, and come from various salinity regimes. Gulf sturgeon is an anadromous fish natal to drainages in the north-central Gulf of Mexico, and as with many endangered species, has a poorly documented parasite community. During Gulf sturgeon tagging and monitoring studies (2016–2019) in the Pascagoula River, MS, USA, species of Argulus were collected from Gulf sturgeon as well as other incidentally captured fishes. Argulus flavescens Wilson, 1916 was found on Gulf sturgeon and flathead catfish, Argulus americanus Wilson, 1902 on bowfin, and Argulus bicolor Bere, 1936 on Atlantic stingray. We provide morphological details and measurements for these species as well as the first confirmed 28S rDNA molecular data. Argulus flavescens was more abundant and prevalent on larger Gulf sturgeon and on sturgeon captured in freshwater rather than estuarine habitats. Our results indicate that A. flacescens may not tolerate estuarine salinities and that the anadromous life-history pattern of Gulf sturgeon could help rid them of A. flavescens when they emigrate from their riverine habitats.
