“…Sporocyst and cercariae of the trematode Bacciger bacciger (Digenea, Faustulidae) (Rudolphi, 1819) were found in the examined visceral mass ( Figure 2 G,H) with an infection rate of about 30%. B. bacciger is a foodborne helminth pathogen commonly infecting the visceral organs of bivalves [ 18 ]. Infection by this parasite has already been reported for several commercial seafoods from the Santa Gilla lagoon including the fish Atherina boyeri (Risso, 1810) and the clams Venerupis aurea (Gmelin, 1791) and Ruditapes decussatus [ 19 ].…”

In this study, the metabolome of Ruditapes decussatus, an economically and ecologically important marine bivalve species widely distributed in the Mediterranean region, was characterized by using proton Nuclear Magnetic Resonance (1H-NMR) spectroscopy. Significant seasonal variations in the content of carbohydrates and free amino acids were observed. The relative amounts of alanine and glycine were found to exhibit the same seasonal pattern as the temperature and salinity at the harvesting site. Several putative sex-specific biomarkers were also discovered. Substantial differences were found for alanine and glycine, whose relative amounts were higher in males, while acetoacetate, choline and phosphocholine were more abundant in female clams. These findings reveal novel insights into the baseline metabolism of the European clam and represent a step forward towards a comprehensive metabolic characterization of the species. Besides providing a holistic view on the prominent nutritional components, the characterization of the metabolome of this bivalve represents an important prerequisite for elucidating the underlying metabolic pathways behind the environment-organism interactions.

“…This species grows to 3,310 µm long, is slightly or distinctly broader with a slightly larger rhynchus, has shorter pre-uterine (about 23–29%) and pre-mouth (about 54–57%) distances. Metacercariae have been reported in the big-scale sand smelt Atherina boyeri Risso, the common goby Pomatoschistus microps (Krøyer), the black-striped pipefish Syngnathus abaster Risso, the leaping mullet Chelon saliens (Risso), the golden grey mullet, C. auratus (Risso) and the gilthead seabream Sparus aurata L. (see Gargouri Ben Abdallah & Maamouri, 2005 ; Culurgioni et al, 2014 ; Culurgioni et al, 2015 ). The first intermediate host is the carpet shell Tapes decussatus (L.) (Gargouri Ben Abdallah & Maamouri, 2005 ).…”

Bucephalus damriyasai n. sp. (Digenea: Bucephalidae) from the blacktip trevally Caranx heberi (Bennett) (Perciformes: Carangidae) off Bali, Indonesia

The new species Bucephalus damriyasai n. sp. is described from Caranx heberi (Bennett) from off Bali, Indonesia. It can be distinguished from other Bucephalus spp. recorded from carangid hosts by its narrow elongate body shape and the relatively long distance between the rhynchus and the vitellarium, as well as other features distinguishing it from individual species. The most similar species are differentiated from B. damriyasai n. sp. as follows: B. carangis Yamaguti, 1970 has a much greater length, the rhynchus is smaller and the cirrus-sac is small, not always reaching to the posterior testis; B. fragilis Velasquez, 1959 is a tiny species, the pre-vitelline distance is short and the caecum is saccular; B. gorgon (Linton, 1905) is much longer and relatively broader, the uterus reaches distinctly anterior to the vitellarium and the rhyncheal tentacles appear more complex; B. labracis Paggi & Orecchia, 1965 is distinctly longer, slightly broader, with a slightly larger rhynchus, and has shorter pre-uterine and pre-mouth distances; B. paraheterotentaculatus Velasquez, 1959 is much longer, relatively rather broad, the rhynchus is said to bear 21 tentacles, the post-testicular region and cirrus-sac reach are longer and the caecum is described as saccular; B. sphyraenae Yamaguti, 1952 is longer, slightly broader, the uterus reaches anteriorly to the vitellarium and the caecum is claviform and oriented anteriorly; B. margaritae Ozaki & Ishibashi, 1934 (syn. B. varicus Manter, 1940) is relatively squat, has shorter pre-vitelline and pre-mouth distances and a longer post-testicular distance and cirrus-sac reach; B. yamagutii Gupta & Singh, 1985 is broader, with a relatively short pre-vitelline distance, the caecum extends anteriorly to the pharynx, but not posteriorly and the rhynchus is said to carry five tentacles. The distinctive features of B. damriyasai n. sp. are compared with those of all other marine Bucephalus spp. in a table. The number of bucephalid trematodes known from Indonesian waters is now 13, two of them await further identification. They have been described from the fish families Carangidae, Platycephalidae, Sciaenidae, Serranidae and Sphyraenidae.

“…The use of fish parasites as bioecological indicators of ecosystem biodiversity and trophic complexity is growing in estuaries and lagoons (Huspeni et al ., 2005; Culurgioni et al ., 2015). The high richness and abundance of helminth parasites, which require several host species and rely on predator‒prey interactions for transmission, are indicative of favourable environmental conditions not only for the parasites themselves but also for all the hosts involved in their life cycles (Culurgioni et al ., 2015). In the same way, the disappearance or decreased occurrence of a parasite in an ecosystem could suggest a decline in the density of a host due to environmental changes (Giari et al ., 2020, 2021).…”

“…A rich parasite community, especially if it includes specialist species, is associated with a diverse and abundant community of hosts; thus, parasites might represent biodiversity indicators in line with the hypothesis that a healthy ecosystem is rich in parasites (Hudson et al ., 2006; Hatcher et al ., 2012). Helminth larval stages are especially sensitive to abiotic factors (Huspeni et al ., 2005) and thus have been proposed to assess the environmental status in brackish systems in combination with standard techniques (Culurgioni et al ., 2015).…”

Given the abundance, heterogeneity and ubiquity of parasitic organisms, understanding how they influence biodiversity, evolution, health and ecosystem functionality is crucial, especially currently when anthropogenic pressures are altering host–parasite balances. This review describes the features, roles and impacts of metazoan parasites of fish occurring in transitional waters (TW). These aquatic ecosystems are highly productive and widespread around the globe and represent most favourable theatres for parasitism given the availability of hosts (invertebrates, fishes and birds) and an increased probability of parasite transmission, especially of those having complex life cycles. Fascinating examples of how parasitism can influence different hierarchical levels of biological systems, from host individuals and populations to entire aquatic communities, through effects on food webs come from this kind of ecosystem. Edible fish of commercial value found in TW can harbour some parasite species, significantly reducing host health, marketability and food safety, with possible economic and public health consequences. Many TW are historically exploited by humans as sources of relevant ecosystem services, including fisheries and aquaculture, and they are highly vulnerable ecosystems. Alteration of TW can be revealed through the study of parasite communities, contributing, as bioindicators, for assessing environmental changes, health and restoration. Fish parasites can provide much information about TW, but this potential appears to be not fully exploited. More studies are necessary to quantify the ecological, economic and medical impacts fish parasites can have on these important ecosystems.
