“…While considerable efforts have been made to investigate the occurrence of endoparasites and other pathogens in Mediterranean fish species (e.g. Carreras-Aubets, 2011;Pérez-i-García et al, 2017), the present investigation represents one of the first to focus on a crustacean multi-specific assemblage, and on brachyuran species. In addition, comparative information on introduced and native crab species is scant, and mostly focused on ectoparasites (Innocenti & Galil, 2007;Goedknegt et al, 2017).…”

The blue crab Callinectes sapidus is an invasive alien species in the Mediterranean Sea. In native habitats, it is subjected to mortalities determined by different pathogens, including the dinoflagellate Hematodinium perezi, a parasite also affecting other brachyuran species. Specifically, Hematodinium-associated disease is acknowledged worldwide as an emerging infection for commercially important crustacean species, but the general diffusion in wild species is unknown. Here, a preliminary screening in C. sapidus hemolymph as well as in three indigenous crabs captured in SE Italy, evidenced the presence of unidentified protozoans in more than 70% of specimen, but the number of suspected Hematodinium cells was very low. The parasites occurrence affected C. sapidus hemocytes functionality, interfering with their role in innate immunity (i.e. phagocytosis or DOPA production). More studies are necessary in order to verify the impact of this alien brachyuran on invaded ecosystems as mediated by the spread of parasites and other pathogens.

“…Despite its name, C. mediterraneus is found throughout the North Atlantic in addition to the Mediterranean Sea (Geistdoerfer 1986 ). It is an active predator and feeds mainly on peracarid crustaceans on or just above the sediment (Carrassón and Matallanas 2002 ; Gates et al 2012 ; Pérez-i-García et al 2017 ), and while it gathers at baited experiments, it has not been observed directly feeding on the bait (Jones et al 2003 ; Gates et al 2012 ). The only other fish species observed by Gates et al ( 2012 ) and collected at abyssal depths by D’Onghia et al ( 2004 ) were the ipnopid (deep-sea tripod fish) Bathypterois dubius , a sit-and-wait predator which is unlikely to be attracted to bait, and the rare Bythitid (viviparous brotula) Cataetyx laticeps which also does not appear to respond to bait (Gates et al 2012 ; Jamieson et al 2017 ).…”

Bathyal and abyssal demersal bait-attending fauna of the Eastern Mediterranean Sea

Baited cameras were deployed over a depth range of 532–5111 m in the Ionian Sea to characterise the large mobile fauna. The planned installation of a neutrino telescope also offers the potential for biological observatories. The current study was intended to aid observatory placement. At increasing depths, sediment was observed to become more uniform and animal burrows and tracks reduced. A total of 10 species of deep-sea fishes were identified from images; four elasmobranchs, which were not recorded deeper than 1841 m, and six teleosts. At depths > 3000 m, including Calypso Deep, the deepest point in the Mediterranean, only one fish species was observed; the Mediterranean grenadier, Coryphaenoides mediterraneus (3400–5111 m), extending this species’ maximum recorded depth to 5111 m. Four species of decapod crustacea could be identified from images. The dressed deep-sea shrimp, Acanthephyra eximia (1346–5111 m) was the only invertebrate recorded at abyssal depths, including the deepest point. A faunal change was detected at ~ 1000 m depth. Incorporating other studies from the Eastern Mediterranean identified additional faunal boundaries at ~ 1500 m and ~ 2500 m. The time from landing the observation equipment to the arrival of the first fish increased exponentially with depth at a slower rate to that observed in the Atlantic Ocean. The estimated density of bait-attending deep-sea fish was, therefore, significantly impoverished compared to the Atlantic Ocean at equivalent depth. Barriers to colonisation, low resource input, and high temperature at depth relative to the Atlantic Ocean are probable causes of the impoverished fauna.Electronic supplementary materialThe online version of this article (10.1007/s00227-018-3413-0) contains supplementary material, which is available to authorized users.

“…The presence of the host-specific bacterial pathogens causes hypertrophy of cells resulting in the formation of basophilic cysts in the epithelium (Nowak & LaPatra, 2006;Stride et al, 2014). More than 100 fish species, both marine and freshwater, are affected by this condition (Chang et al, 2016;Pérez-i-García et al, 2017;Sellyei et al, 2017;Shamsi et al, 2020;Sood et al, 2017Sood et al, , 2019Steigen et al, 2015Steigen et al, , 2018Stride et al, 2014). Epitheliocystis has been reported in both wild and cultured fish but cultured fish were usually affected more severely (Nowak & LaPatra, 2006).…”
