“…This is consistent with previous findings of increased transmission 463 of gyrodactylid species, such as G. salaris, which are able to infect both hosts when high 464 densities of both three-spined and nine-spined stickleback are found (Soleng et al 1999). 465…”

SUMMARY 7Patterns in parasite community structure are often observed in natural systems and an important 8 question in parasite ecology is whether such patterns are repeatable across time and space. Field 9 studies commonly look at spatial or temporal repeatability of patterns, but they are rarely 10 investigated in conjunction. We use a large data set on the macroparasites of the three-spined 11 stickleback, Gasterosteus aculeatus L., collected from 14 locations on North Uist, Scotland 12 over an eight year period to investigate: 1) repeatability of patterns in parasite communities 13 among populations and whether variation is consistent across years, 2) whether variation 14 between years can be explained by climatic variation and progression of the season and 3) 15 whether variation in habitat characteristics explain population differences. Differences in 16 relative abundance and prevalence across populations were observed in a number of parasites 17 investigated indicating a lack of consistency across years in numerous parasite community 18 measures, however differences between populations in the prevalence and abundance of some 19 parasites were consistent throughout the study. Average temperature did not affect parasite 20 community and progression of the season was only significant for two of 13 community 21 measures. Two of the six habitat characteristics investigated (pH and calcium concentration) 22 significantly affected parasite presence. 23

“…It is known that mostly the water temperature, conditioned to pluviosity, has effect on the biology of hosts and parasites (Oliver, 1982;Soleng et al, 1999). It is the main abiotic factor responsible for regulating reproduction of monogeneans; in general, the embryonic period decrease with the increase of temperature and, for some species, there is a delay in the eggs eclosion under low temperatures (Gannicott and Tinsley, 1998).…”

Gill metazoan parasites of the spotted goatfish Pseudupeneus maculatus (Ostheichthyes: Mullidae) from the Coast of Pernambuco, northeastern Brazil

et al. 2017

This study evaluated the parasite fauna on the gills of spotted goatfish Pseudupeneus maculatus captured in the dry and rainy seasons in the coast of the State of Pernambuco, Brazil. Eight parasite species were identified belonging to the following taxa: Monogenea (Haliotrema caraïbensis, Haliotrema caballeroi and Haliotrema golvani); Crustacea (Rocinela signata, Hamaticolax scutigerulus and Caligidae gen. sp.) and Cestoda (Nybelinia indica and Pseudolacistorhynchus noodti). The most prevalent parasites were: Monogenea (100%), H. scutigerulus (35%), N. indica (11.7%), R. signata (8.3%), Caligidae gen. sp. (3.33%) and P. noodti (0.83%). Values of infestation are compared to other studies, and the uncommon occurrence of Trypanorhyncha on the gills suggests that the spotted goatfish could be an intermediate host for the parasite.Keywords: marine fish, infestation, parasitology.

“…The parasite possesses no specific transmission stage or swimming ability (Bakke et al 1992, Soleng et al 1999, Olstad et al 2006. Gyrodactylids are considered host specific, but G. salaris has been recorded in a relatively wide range of hosts (Harris et al 2004).…”

“…However, under natural conditions, the parasite is only known to be pathogenic to Atlantic salmon (Bakke et al 1992). G. salaris fecundity, longevity and transmission rates are influenced by water temperature (Jansen & Bakke 1991, Soleng et al 1999, Cable et al 2000. Additionally, the parasite is known to have limited tolerance to salt water (Soleng & Bakke 1997).…”

Geographic risk factors for inter-river dispersal of Gyrodactylus salaris in fjord systems in Norway

Gyrodactylus salaris has been recorded in 46 Norwegian rivers since 1975 and is considered a threat to Atlantic salmon stocks. The primary introductions of G. salaris (primary infected rivers) have been accounted for by specific events, as reported in the literature. The parasite has subsequently dispersed to adjacent localities (secondary infected rivers). The objective of this paper is to address the occurrence of secondary infections by examining the hypothesis of inter-river dispersal of G. salaris. A dispersal model for the secondary river infections via migrating infected fish is proposed. Due to the limited tolerance of G. salaris to salinity, both freshwater inflow to dispersal pathways and dispersal distance were expected to influence the probability of inter-river dispersal. Eighteen rivers were categorised as primary infected rivers, 28 as secondary infected rivers, and 54 as rivers at risk. Four risk factors: the log 10 freshwater inflow; the dispersal distance; the time at risk; and the salmon harvest were combined in a multi-variable logistic regression model of the probability of secondary infection. The final multi-variable model included log 10 freshwater inflow (Wald chisquare = 9.93) and dispersal distance (Wald chi-square = 6.48). Receiver operating characteristic analyses of the final model supported freshwater inflow as a strong predictor of G. salaris infection status. The strong influence of the freshwater inflow on the probability of secondary infection adds further support to the hypothesis of inter-river dispersal of G. salaris through fjords.
