“…A more concerning disease issue associated with P. hypophthalmus is that many of these diseases and parasitic infections are often not clinically apparent (nor classed as notifiable diseases in the country of origin). This makes it quite likely that septicaemic fish (as detected in some aquaculture facilities in India: Chaudhary et al, ) could be harvested for human consumption. This could pose a high risk of infection for humans and other aquatic alike, especially in cases where the effluent water from P. hypophthalmus culture ponds is not treated prior to its discharge into receiving water bodies or canals.…”

“…Fish losses due to A. hydrophila outbreaks in P. hypophthalmus production systems of Vietnam have been documented (Subagja, Slembrouck, Hung, & Legendre, 1999). Furthermore, the NN monogenean parasite Thaparocleidus caecus from Southeast Asia (Chaudhary et al, 2014) has been found to have established in India, though without evidence of impacts on the native fish fauna (Chaudhary et al, 2014).…”

The European Non‐native Species in Aquaculture Risk Analysis Scheme (ENSARS) was used to assess one of the most popular aquaculture species in the world, the striped catfish Pangasianodon hypophthalmus (Sauvage, 1878), in two locations of southern Anatolia (Turkey). The overall mean risk score generated for P. hypophthalmus by the ENSARS Organism module (which assesses the risks of introduction, establishment, dispersal and impact) indicated that the species poses a medium risk under current climatic conditions. All other ENSARS modules rendered scores that indicated a moderately low risk under current climatic conditions. However, the risks of introducing novel diseases and the actual use (e.g. deliberate introduction to the natural habitats or food market) of the species both attracted scores indicating a medium risk. Confidence levels were medium or high for all modules except the Socio‐economic, with low confidence values also attributed to the risks for farming process of the organism, and its overall risk of spread into the wild during farming procedures and to marketing impacts. Recommendations are provided for further use of the ENSARS scheme, especially for a a priori assessment of potential aquaculture species in Turkey, where the sector has been remarkably developing in the last decades.

During an investigation of the diversity of monogenean parasites in Meerut, U.P., India, the exotic freshwater fish Gymnocorymbus ternetzi was found infected with the gill dactylogyrid species of Diaphorocleidus Jogunoori et al. 2004. Using morphological study, the present monogeneans were found similar in morphology of anchors, bars and male copulatory organ with D. armillatus Jogunoori et al. 2004. This is the first genetic characterization of D. armillatus based on the analysis of 18S ribosomal RNA sequence (1800 bp) and associated with morphological redescription. Our study suggests that more molecular investigation is required on Diaphorocleidus species for deducing correct phylogenetic position of D. armillatus.

The phylogenetic studies on monogeneans of the genus Thaparocleidus parasitizing W. attu in India was inferred from 18S rDNA gene data. Out of species of Thaparocleidus, one new, T. armillatus sp. n., is described herein which distinguished from its congener species in the shapes and sizes of sclerotized structures and rest of the two species, T. indicus and T. wallagonius are redescribed morphologically as well as validated and confirmed by molecular means also. Besides the above, T. gangus was also included in the molecular analysis as it is recently described on the basis of morphology only. The phylogenetic tree was also reconstructed in order to elucidate the taxonomic status of Thaparocleidus armillatus sp. n., T. indicus, T. wallagonius and T. gangus. This research reports for the first time, the molecular phylogenetic analysis of 18S rDNA gene for four species belonging to the genus Thaparocleidus from W. attu collected off the River Ganga in India. In phylogram, all four species of Thapaocleidus come in a single clade that confirmed their monophyletic status. A very low interspecific variability was observed in T. armillatus sp. n. and T. wallagonius suggesting that these species are highly similar in morphology. Correspondingly, T. indicus and T. gangus also showed low interspecific variability which too signifies their morphological similarities in their sclerotized structures. Our result suggested that all four species taken in the present investigation from India are monophyletic and it is also observed that morphological similarities in the sclerotized structures are well correlated with phylogeny.
