“…As they feed on tissues on their attachment site, they cause severe lesions and give physical damage to their fish hosts. Cymothoid parasites are also vectors of secondary bacterial and viral infections which lead mortalities particularly in finfish culture (Hadfield & Smit, 2019). These direct and indirect effects give rise to economic losses.…”

Since 2014, an invasive alien fish species, lionfish, Pterois miles (Bennett, 1828) has been started to distribute in the Turkish Mediterranean Sea coasts and spread out to the Aegean Sea. In the present study, a Cymothoid fish parasite, Nerocila bivittata (Risso, 1816) is reported from the pectoral fin of P. miles caught from the Gulf of Iskenderun (Northeastern Mediterranean) and Bodrum, Turkey (Aegean Sea Coast). This study is the first record of N. bivittata on lionfish P. miles caught from Gulf of Iskenderun. Key diagnostic characters of N. bivittata, some morphological differences observed between the newly collected material of N. bivittata and its previous descriptions, in addition to newly observed additional characters were presented.

“…In addition to being directly affected by pathogens, copepods act as mechanical and biological vectors, reservoirs, and alternative hosts for a wide range of pathogens, many of commercial relevance. Parasitic copepods, especially of the genera Caligus and Lepeophtheirus (Caligidae) and Ergasilus (Ergasilidae), have been shown to act or have high potential to act as vectors for bacteria and viruses between fishes [96]. Some cases are relatively well known: salmon lice acting in different vectoring capacities for viruses (and influencing susceptibility to viruses; [86]) and pathogenic bacteria, for example, Aeromonas salmonicida, Tenacibaculum maritimum, Pseudomonas, and Vibrio [97,98].…”

“…Caligus elongatus is a potential vector for Photobacterium damsela in seabass [99]. Ergasilus rotundicorpus is suspected to act as vector for the lymphocystis virus in marine and freshwater fishes [96]. The fish-pathogenic protist (Neo)paramoeba perurans may also be transferred via L. salmonis as vector [100].…”

“…Being exhibited a wide range of morphological adaptation, caligids massively entrench skin, inner operculum wall and gills, and feed on host fish mucus, tissues, and blood (Kabata 1974;Boxshall and Halsey 2004;Smit et al 2019). Caligid infection on farmed marine fishes often causes severe hemorrhage and erosion on the skin, fins, and eyes facilitating the secondary viral and bacterial infections (Nylund et al 1994;Nowak et al 2011;Hadfield and Smit 2019).…”

This study reports population structure, host preference, species diversity, seasonality, and genetic variability of caligids infecting the marine food fishes of Kerala coast, India. The survey included 22,629 fishes belonging to 85 species, 65 genera, and 34 families sampled from 6 different stations. Of which 24 species of fish from 24 genera and 14 families were found infected with caligids revealing 5% susceptibility. The recovered caligids included 26 species comprising eight genera and genus Caligus was the dominant one with 18 species (69.23%; 18 out of 26). The prevalence was highly varied irrespective of the host fish family. Sampling stations from the northern Kerala showed higher values of abundance, species number, richness and diversity indices compared to the southern stations. k-dominance plot showed the highest dominance and low diversity of caligids in Azhikkal (Northern station) and lower dominance and high diversity in Kalamukku and Thoppumpadi (Southern stations). Seasonal prevalence revealed the highest infection of caligids during post-monsoon and the lowest during monsoon season. Molecular level identification of recovered caligids using mCOI gene revealed 80 to 93% sequence identity with other parasitic copepods based on BLAST results. Phylogenetically, species of Caligus displayed intra-genus variation of 13-27% (k2p genetic distance). The species of the family Caligidae formed distinct clades from that of the families Lernaeopodidae and Lernanthropidae. Present study also documented host preference, site of infection, seasonality, and genetic divergence of the recovered caligids, all of which are relevant for further exploration of the species diversity and genetic variation of caligids along the Indian coasts and Indo-pacific region as well.
