Digenean metacercariae of fishes from the lagoon flats of Palmyra Atoll, Eastern Indo-Pacific

et al. 2012

Although many studies on the taxonomy of digenean trematodes of marine fishes have been completed in the Eastern Indo-Pacific (EIP) marine ecoregion, only a few have considered metacercarial stages. Here, the results are presented of a taxonomic survey of the digenean metacercariae of fishes from Palmyra Atoll, a remote and relatively pristine US National Wildlife Refuge located 1680 km SSW of Hawaii. Up to 425 individual fish were collected, comprising 42 fish species, from the sand flats bordering the lagoon of the atoll. Quantitative parasitological examinations of each fish were performed. Morphological descriptions of the encountered digenean metacercariae are provided, together with their prevalence, mean intensities, host and tissue-use. Up to 33,964 individuals were recovered representing 19 digenean metacercaria species from eight families. The species composition of digeneans in lagoon fishes at Palmyra Atoll is a subset of what has previously been reported for the EIP. Further, the large diversity and abundance of metacercariae reported in this study highlight the utility of including this group in future ecological research in the EIP marine ecoregion.

“…Copepods were examined and dissected according to routine methods . Permanent slides were made of monogeneans, digeneans and cestodes according to routine methods Bray & Justine 2006;Justine 2005, respectively). Nematodes were fixed alive in nearboiling 4% formalin, or sometimes in boiling 70% ethanol or near-boiling saline, and later examined in glycerine; specimens were also prepared for scanning electron microscopy .…”

Parasites were collected from 17 species of emperors and emperor bream (Lethrinidae) in the waters off New Caledonia, South Pacific. Host-parasite and parasite-hosts lists are provided, with a total of 188 host-parasite combinations (11 per fish species), including 81 identifications at the species level. A total of 52 parasites were identified at the species level, and 40 new host records were found. Results are presented for larval isopods, copepods (16 species), monogeneans (24), digeneans (27), cestodes (11) and nematodes (10). When results were restricted to the four best-sampled fish species for which more than 30 specimens were examined, the number of host-parasite combinations was 22.25 per fish species, and the number of parasite taxa identified at the species level was 9.5 per fish species. From these data, the total number of metazoan parasite species predicted from all lethrinid species of New Caledonia, based on a classification of fish sizes using length in three categories, is 340, i.e. 13 per fish species. A biogeographical comparison with Heron Island on the Great Barrier Reef (Queensland, Australia) was possible only for a single fish species, Lethrinus miniatus: in a total of 65 host-parasite combinations, only five taxa identified at the species level (three monogeneans and two digeneans) were shared at both localities. Parasite biodiversity in lethrinids was of similar magnitude to that in groupers (Serranidae Epinephelinae) in the same area, and this study confirms a previous prediction of 10 parasite species per coral reef fish species. Although this study required significant sampling and identification, we estimate that only 13% of the parasites of lethrinids are known in New Caledonia.

“…The fish was spear-fished (18.v.2005, 22°19'114S, 166°27'092E) and immediately brought back to the laboratory, photographed and measured (fork length 1280 mm, weight 45 kg). Other parasites collected in this fish have already been described (digeneans: Bray & Justine 2006;trypanorhynch cestodes: Beveridge et al 2007). A second, much smaller (fork length 395 mm, weight 795 g) specimen (designated as JNC2130) was spear-fished in Baie Maa, New Caledonia (9.iii.2007, 22°12'780S, 166°19'933E).…”

Eleven species were differentiated among more than 300 monogeneans collected on the gills of two wild malabar groupers, Epinephelus malabaricus, caught in the lagoon of New Caledonia, South Pacific. Diplectanids included seven species of Pseudorhabdosynochus Yamaguti, 1958, which were differentiated mainly on the basis of morphology of the sclerotised vagina. P. manifestus n. sp. was the most abundant species (65–80% of the diplectanids); all other species were rare. It is characterised by morphology of its vagina, in general shape of a question mark. P. malabaricus n. sp. and P. maternus n. sp. both have a vagina with two spherical chambers, and are differentiated on the basis of measurements of these chambers. P. manipulus n. sp. has an elongate vagina with a long primary chamber. P. marcellus n. sp. has a long vagina with two bends. P. maaensis n. sp. has a long vagina with a straight primary canal and the two chambers united in a common sclerotised part. Two specimens were provisorily attributed to P. cf. shenzhenensis Yang, Zeng & Gibson, 2005. Diplectanum maa n. sp. has a funnel-shaped male copulatory organ. Two species of Haliotrema (Ancyrocephal-idae) and Pseudomegalocotyla sp. (Capsalidae) are mentioned but not described. The presence of 11 species of monogeneans in this fish, after a previous published record of 12 species in E. maculatus, provides additional argument for existence of a very rich fauna of monogeneans in groupers, and an impressive parasite biodiversity in coral reef fish in general. Lists are given for other parasites of the malabar grouper, including monogeneans, digeneans, cestodes and nematodes, including new records from New Caledonia; more than 40 parasite species have been recorded in the literature. The malabar grouper is a major fish for aquaculture in South East Asia and a precise description of its parasites is needed for identification of potential threats to farmed fish.
