“…Regarding the plerocercoid, the prevalences that we found in this study were similar to those reported for tetraphyllidean plerocercoids in the NE Atlantic Ocean (MacKenzie, ), but there is no previous record of Tetraphyllidea in M. poutassou from the Mediterranean Sea. After comparing anisakids in M. poutassou from the NW Mediterranean Sea (this study) with anisakids found elsewhere (Molina‐Fernández et al, ), it can be seen that the fishing area is a potential indicator of the infection by anisakids (Molina‐Fernández et al, ; Rello et al, ). Comparatively, our results for Anisakis spp.…”

A combination of traditional and emerging methodologies was used to assess the trade‐offs between several life‐history traits (linked to reproduction and condition) and parasitism in a commercially‐exploited cold‐water species, blue whiting Micromesistius poutassou, in the Mediterranean Sea. The use of histological and gravimetric methods revealed conflicting evidence as to the fecundity type (indeterminate or determinate) of this species. Moreover, there seem to be condition‐mediated compensations between egg quality and egg quantity. The effects of parasitism on reproduction and condition are species‐specific and occur mainly at high intensities of infection; they include a lower batch fecundity (affecting reproductive potential), a higher hepatosomatic index and a higher spleen‐somatic index. Considering the fact that larger fish spawn more eggs and that the minimum landing size is lower than the size at maturity, these results may have implications for the future management of M. poutassou stocks in the Mediterranean Sea. Local environmental conditions may account for geographical differences regarding infection in M. poutassou. Altogether, the results support the idea that the complex trade‐offs between parasitism, reproduction and condition need to be considered in order to understand the status of cold‐water species such as M. poutassou.

Marine nematodes of the genus Anisakis are common parasites of a wide range of aquatic organisms. Public interest is primarily based on their importance as zoonotic agents of the human Anisakiasis, a severe infection of the gastro-intestinal tract as result of consuming live larvae in insufficiently cooked fish dishes. The diverse nature of external impacts unequally influencing larval and adult stages of marine endohelminth parasites requires the consideration of both abiotic and biotic factors. Whereas abiotic factors are generally more relevant for early life stages and might also be linked to intermediate hosts, definitive hosts are indispensable for a parasite’s reproduction. In order to better understand the uneven occurrence of parasites in fish species, we here use the maximum entropy approach (Maxent) to model the habitat suitability for nine Anisakis species accounting for abiotic parameters as well as biotic data (definitive hosts). The modelled habitat suitability reflects the observed distribution quite well for all Anisakis species, however, in some cases, habitat suitability exceeded the known geographical distribution, suggesting a wider distribution than presently recorded. We suggest that integrative modelling combining abiotic and biotic parameters is a valid approach for habitat suitability assessments of Anisakis, and potentially other marine parasite species.

“…in Brama australis in three southern Chilean localities: 16.8% in Lebu, 10.6% in Calbuco and 6.7% in Punta Arenas (Oliva et al, 2016). Several data demonstrate the importance of this nematode parasite in public health and the risk of infection due to this seafood-borne disease worldwide, which affects many different fish species destined for human consumption such as: Chilean jack mackerel (Trachurus murphyi) (George-Nascimento et al, 1983), sardines (Sardina pilchardus) and anchovies (Engraulis encrasicolus) a b c a d (Serracca et al, 2014;Cavallero et al, 2015;Molina-Fernández et al, 2015), Atlantic mackerel (Scomber scombrus) (Pekmezci, 2014), lamprey (Petromyzon marinus) (Bao et al, 2013), golden kingklip (Genypterus blacodes) and snoek (Thyrsites atun) . Respecting the salmon farmed industry, Marty (2008) described the presence of anisakid larvae in the viscera of a farmed Atlantic salmon (Salmo salar), however, the prevalence described was very low (0.11%) probably because of artificial diets which also contain medications designated for salmon (Sepúlveda et al, 2004).…”

The main objective of this work was to determine the presence of anisakid larvae in fresh Chilean hake Merluccius gayi gayi coming from the coastal area near the city of Talca, Chile, commonly commercialized by a regional fish supply center located in the same city. Flesh and viscera of 214 fish were analyzed via direct observation, and the prevalence of parasitism was calculated. The results showed a prevalence of 100% and 24.3% in viscera and flesh, respectively. Morphologic characterization of 138 randomly selected larvae was performed via diaphanization technique, observing 106 larvae of Anisakis spp., 13 larvae of Pseudoterranova spp. and 19 nematodes classified as “unidentified.” All larvae here analyzed were viable based on the spontaneous movement ability of parasites. Overall, the high prevalence of fish infected with Anisakidae larvae highlights the importance of taking early intervention actions in order to prevent the occurrence of anisakidosis in the human Chilean population; particularly critical given the current culinary preference for raw fish dishes such as ceviche and sushi, which poses a public health issue.
