“…The determinants of parasite richness of fish have been traditionally investigated in freshwater species (Bush et al 1990, Bell & Burt 1991, Guegan et al 1992, Guegan & Kennedy 1993, Aho & Bush 1993, and it is obvious that parasite community ecology of freshwater fish has contributed considerably to the development of our general knowledge of parasite biodiversity (for niarine examples see Campbell et al 1980, Rohde 1988, Holmes 1990, Rohde et al 1995. All these investigations have focused on the characterization of the determinants of parasite richness such as host geographical range, host body size or host diet variables.…”

Data on parasites of Mediterranean Sea fishes, collected from previous published surveys, were used to test 5 hypotheses concerning the determinants of parasite species richness. A total of 170 parasite species belonging to 5 distinct taxonomic groups (nematodes, acanthocephalans, digeneans, monogeneans and crustaceans) were identified from 79 marine fish species (3904 individuals) collected at a regional scale. Five independent variables concerning host life traits (body size, diet, range, abundance and schooling) were investigated and controlled for host sampling effort. A comparative analysis uslng the independent contrasts method was conducted In order to avoid phylogenetic confounding effects. We demonstrate the importance of taking host sampling effort into account when Investigating the determinants of parasite species richness. Monogeneans were the only group for which the species nchness showed a significant correlation with some of the variables studied. Parasite specles richness of monogeneans was posltlvely correlated with host body size and negatively correlated with host species abundance. The pos~tive relationship between fish body size and the number of parasite specles on a regional scale may b e explained by the hypothesis that larger host body size increases host vagility which in turn enhances exposure to more and more parasite species. Our findings disagree with previous studies that did not take either phylogenetic confounding effects or geographic scale into account. We demonstrate the importance of using phylogenetic information in comparative analyses by showing that fish body size was not correlated with geographical range when using phylogenetic independent contrasts. We also suggest that studying parasites of host species from the same geographical region avolds the problem of confounding various assemblages of hosts w~t h distinct histories.

“…Moreover, deep-water snappers have a markedly different parasitofauna, excluding ancyrocephalids, from the snappers found in shallower waters (Yamaguti 1968). In general, the monogeneans species found on deep-sea fishes are largely unrelated to those found on surface-water fishes in the same geographical area (Rohde 1988(Rohde , 2002. Even though native Hawaiian snappers are not syntopic with introduced snappers and parasite transfer is highly unlikely, we recognize that parasitological data remain to be collected to confirm the absence of such transfer.…”

The bluestriped snapper Lutjanus kasmira and the blacktail snapper L. fulvus were deliberately introduced in the Hawaiian Archipelago from French Polynesia in the late 1950s to enhance local fisheries. These species rapidly spread all over the Windward Islands, became extremely abundant and, therefore, caused controversial environmental concerns. A comparison of the whole metazoan parasite community of L. kasmira and L. fulvus was performed between their native ranges in French Polynesia (Moorea Island in the Society Archipelago and Ua Huka in the Marquesas Islands) and their introduced range in O'ahu, Hawaii, USA. We suggest that 8 monogenean species have been introduced with L. kasmira and L. fulvus into the Hawaiian Archipelago from French Polynesia; 2 other species as well as one nematode should be referred to as cryptogenic. Moreover, experimental mortality conducted on monogeneans found in Polynesia emphasizes the inefficiency of anti-parasite treatment which was performed 50 yr ago, explaining possible parasite introduction. Finally, we discuss the potential threat of exotic parasites to the native fish community in the Hawaiian Archipelago and conclude that the absence of co-evolved hosts prevents parasite transfer from non-indigenous to native fishes as monogeneans are highly specific.KEY WORDS: Parasite community · Non-indigenous species · Lutjanus · Hawaii · Polynesia · Copper sulphate Resale or republication not permitted without written consent of the publisherDis Aquat Org 85: [133][134][135][136][137][138][139][140][141][142][143][144][145] 2009 of exotic parasites is well known (Dobson & Foufopoulos 2001, Grosholz 2002, Prenter et al. 2004, BondadReantaso et al. 2005. For example, introduced parasites have decimated naïve host populations in several cases (Anderson & May 1986, Harvell et al. 1999, Hay et al. 2004, Prenter et al. 2004. The best known example among fish is the decimation of the Aral Sea sturgeon Acipenser nudiventris by the monogenean Nitzchia sturionis. This parasite was accidentally introduced to the Aral Sea with the Caspian Sea sturgeon Huso huso in the 1930s (Dogiel & Lutta 1937). However, parasites remain an underestimated component of total biodiversity (Luque & Poulin 2007), usually because of their small size and cryptic way of life. Thus, the introduction of parasites in a new ecosystem is of concern in a conservational context and remains poorly studied in the wild.The Hawaiian Islands are among the most geographically and hydrographically isolated in the world and, thus, exhibit a unique reef fish assemblage. This isolation has resulted in some major reef fish taxa being totally absent or poorly represented. Further, unlike other islands in the Indo-Pacific, the Hawaiian Islands lack reef fish species that support valuable commercial and recreational fisheries such as shallow-water groupers and snappers (Oda & Parrish 1981, Coleman et al. 2000. Thus, in the late 1950s, the Hawaiian government introduced various reef fishes to the Hawaiian Islands from Frenc...

An annotated list of fish parasites (Isopoda, Copepoda, Monogenea, Digenea, Cestoda, Nematoda) collected from Snappers and Bream (Lutjanidae, Nemipteridae, Caesionidae) in New Caledonia confirms high parasite biodiversity on coral reef fish

BackgroundCoral reefs are areas of maximum biodiversity, but the parasites of coral reef fishes, and especially their species richness, are not well known. Over an 8-year period, parasites were collected from 24 species of Lutjanidae, Nemipteridae and Caesionidae off New Caledonia, South Pacific.ResultsHost-parasite and parasite-host lists are provided, with a total of 207 host-parasite combinations and 58 parasite species identified at the species level, with 27 new host records. Results are presented for isopods, copepods, monogeneans, digeneans, cestodes and nematodes. When results are restricted to well-sampled reef fish species (sample size > 30), the number of host-parasite combinations is 20–25 per fish species, and the number of parasites identified at the species level is 9–13 per fish species. Lutjanids include reef-associated fish and deeper sea fish from the outer slopes of the coral reef: fish from both milieus were compared. Surprisingly, parasite biodiversity was higher in deeper sea fish than in reef fish (host-parasite combinations: 12.50 vs 10.13, number of species per fish 3.75 vs 3.00); however, we identified four biases which diminish the validity of this comparison. Finally, these results and previously published results allow us to propose a generalization of parasite biodiversity for four major families of reef-associated fishes (Lutjanidae, Nemipteridae, Serranidae and Lethrinidae): well-sampled fish have a mean of 20 host-parasite combinations per fish species, and the number of parasites identified at the species level is 10 per fish species.ConclusionsSince all precautions have been taken to minimize taxon numbers, it is safe to affirm than the number of fish parasites is at least ten times the number of fish species in coral reefs, for species of similar size or larger than the species in the four families studied; this is a major improvement to our estimate of biodiversity in coral reefs. Our results suggest that extinction of a coral reef fish species would eventually result in the coextinction of at least ten species of parasites.
