Al-Zubaidy Department of Marine Biology and Fisheries, Faculty of Marine Science and Environment, Hodeidah University, Yemen e-mail: [email protected] Abstract. A total of 85 fish specimens of the great barracuda, Sphyraena barracuda (Edwards, 1771) from the Red Sea, Yemeni coastal waters were examined for infection with the polyopisthocotylean monogeneans during the period from October 2009 till May 2010. The results showed the occurrence of two species of these parasites; Vallisiopsis contorta Subhapradha, 1951 and Pentatres sphyraenae Euzet and Razarihelisoa, 1959. The occurrence of these monogeneans represents their first record from the Yemeni fishes of the Red Sea. Key words: Monogenea, Polyopisthocotylea, Fishes, Red Sea, Yemen. Introduction Fish have a great importance and significance in the life of mankind. These are most common and widely distributed almost in all parts of the world. Marine fish constitute about 90% of total world fish production (approximately 80 million tons) but the availability of fish supplies can be affected by parasites and diseases, which could ultimately affect nutrition and hence economics of populations (Rohde, 1993 and Hadfield, 2007). 3 4 A.B. Al-Zubaidy The total number of described fish helminthes exceeds far more than 30.000 species (Williams and Jones, 1994). The Neodermata or parasitic Platyhelminthes comprise an enormous diversity of species that occur in all seas, rivers and lakes and on all continental land masses. They include trematodes, cestodes and monogeneans (Richard and Justine, 2001). Monogeneans are ectoparasites of fishes exhibiting a relatively high degree of host specificity (Williams and Jones, 1994). Monogeneans included about 720 genera distributed among 53 families (Boeger and Kritsky, 2001). Monogenea comprise two very distinct groups, the Monopisthocotylea and the Polyopisthocotylea, which differ considerably in respect of their morphology, pathogenicity, treatment and host response (Purivirojkul, 2008). There are relatively few studies concerning fish monogeneans of the Red Sea (Paperna, 1972 a, b, c; Paperna et al., 1984; Diamant and Paperna, 1986; Diamant, 1989; Tawfik et al., 2006; Bayoumy et al., 2007; Kritsky et al., 2007 and Al-Zubaidy, 2013). The present Study concerned with the record of two polyopisthocotylans from gills of the great barracuda, Sphyraena barracuda (Edwards, 1771) for the first time in the Red Sea, Yemeni coastal waters. Material and Methods Investigated fishes used in this study were obtained from a local fish market (Al-Mehwat) at Hodeidah city, Yemen, during the period from October 2009 till May 2010. Specimens were placed in bags with ice and transported to the laboratory of the Department of Marine Biology and Fisheries, Hodeidah University. Scientific names of hosts are adopted from Froese and Pauly(2012). The gills from both sides of fishes were removed one by one by cutting them at their extremities and they were examined immediately in seawater. Monogeneans were removed alive with fine needles and immediately prepared for slides. Live specimens were fixed with AFA (alcohol-formalin-acetic acid) and mounted in glycerol gelatin (Malmberg, 1970). Phase contrast microscopy was used to study the hard parts of the haptor and the copulatory organ of the reproductive system. For descriptions and measurements are calibrated using an optical microscope. The drawings were made using a camera Lucida and The First Record of Two Polyopisthocotylean Monogeneans on Gill of the … 5 photographs were made with a Samsung digital camera, 10.1 mega pixels. Parasite measurements were given as range as well as the mean in parentheses. Parasitic identifications were done according to Yamaguti (1963, 1968). Parasite identifications were ascertained by Prof. Dr. Jean-Lou Justine, France, and Prof. Dr. Delane C. Kritsky, U.S.A. Results and Discussion Two species of monogeneans belonging to the subclass Polyopisthocotylea were found on gills of Sphyraena barracuda collected from Red Sea, Yemen coast. These polyopisthocotylean monogeneans are arranged in the following systematic account of WoRMS (2013). Phylum Platyhelminthes Class Monogenea Subclass Polyopisthocotylea Order Mazocraeidea Family Protomicrocotylidae Subfamily Vallisiinae Vallisiopsis contorta Subhapradha, 1951 Family Chauhaneidae Subfamily Pentatrinae Pentatres sphyraenae Euzet and Razarihelisoa,1959. 1- Vallisiopsis contorta Subhapradha, 1951 (Fig. 1 and 2) Description: Body, 3.0-3.9 (3.6) mm in length, with a maximum width of 1.3-1.9 (1.5) mm, is bent on itself and also twisted, the anterior part lies at a right angle to the posterior part, and the dorsoventral axis of the anterior part is twisted. The entire surface of the body is transversely ringed; the posterior end of the body bears a pair of anchors, which are 0.025 mm long. Oral sucker 0.028-0.034 (0.032) long by 0.025-0.034 (0.030) mm wide. The haptor is asymmetrical. There are eight clamps, four on each side of the haptor. Those on one side lie close together and are nearer the anchors, while those on the opposite side are farther apart and are born on distinct lobes of the body. 6 A.B. Al-Zubaidy The clamp skeleton is typically discocotylid in pattern and bears a pair of accessory sclerites in connection with the middle piece, which are very similar to the' v-shape'. The width of the clamp is 0.057-0.062 (0.059) mm, hamuli 0.027-0.029 (0.028) mm long, shafts 0.016-0.018 (0.017) mm long; dorsal root 0.010- 0.012 (0.011) mm long, ventral root 0.008-0.010 (0.009) mm long; atrial spines 0.012-0.015 (0.013) mm long. The oesophagus is long and extends below the genital pore. Fig. 1. Camera lucida drawings of Vallisiopsis contorta from Red Sea fish. A- Entire specimen; B- Clamp skeleton; C- Egg. The First Record of Two Polyopisthocotylean Monogeneans on Gill of the … 7 The intestinal crura are branched. The two limbs of the intestine join together posterior to the gonads. The testes are follicular, overlap the anterior half of the ovary and extend beyond it. The ovary is in the form of a double loop extending posterior to the testes. The vitellaria are follicular and coextensive with the intestinal rami. The vitelline reservoir lies adjacent to the ovary. The eggs are spindle shaped and have polar filaments. Host and Locality: Great barracuda, Sphyraena barracuda (family Sphyraenidae) from the Red Sea, Yemeni coastal waters. Length and weight of infected fishes ranged between 20-65 cm and 0.410 -2.100 kg, respectively. Infection Parameters: Mean prevalence of the infection was 16.47%, while the intensity of infection was 1-2 (1.6) worms. Record of Specimens: Twenty-three specimens of this parasite were collected. Parasites were observed frequently on larger fishes (30- 65 cm, n=78) rather than on smaller fishes (20-29 cm, n= 7). The impact of the parasite burden is dependent not on the intensity (number of parasites per fish) but rather on the number of parasites in relation to the size of host. The gill surface of fish increases markedly with body length (Hughes, 1966) and the space available for parasite attachment therefore increases with host size (Buchmann, 1989). Previous Records: This parasite was previously reported in Lactarias lactarias Bloch and Schneider, 1801 (Lactariidae) from Madras coast by Subhapradha (1951) and in Sphyraena commersonii Cuvier, 1829 (synonym of S. barracuda) from Madagascar by Euzet and Razarihelisoa (1959). Habitat: The parasites were found on the second gill, between the two rows of gill filaments and were firmly attached to them with the aid of the clamps. According to Hanek and Fernando (1978), the differences in water current over the gill surface were considered to be important in determining the distribution of parasites on the gills. Most polyopisthocotyleans are not overtly pathogenic. As polyopisthocotyleans are blood feeders, the host does not show any pathological signs or host response compared to other parasites which browse widely on epithelium while feeding as do the mucus and epithelial feeders. These have attachment clamps which do not penetrate 8 A.B. Al-Zubaidy deeply into host tissues like the hamuli and marginal hooklets found in other monogeneans. Thoney (1986) reported that laboratory reared Sebastes melanops Girard, 1856, heavily infested with Microcotyle sebastis, did not show any signs of stress or pathology. Higher intensities of parasites may weaken the host, permitting capture by predatory fish or infection by other disease agents. When a certain number of polyopisthocotyleans occur on an individual host, they can become pathogenic and cause mortalities at the final stage. Documented examples of pathology caused by polyopisthocotyleans include: Discocotyle sagittata which cause serious gill damage to salmonids in Europe and Axine heterocerca which killed sea cage-cultured Siganus sp. in Japan (Roberts, 1978); Heteraxine heterocerca affecting Siganus quinqueradiata, Microcotyle sebastis damaging the rockfishes Sebastes melanops (Thoney and Hargis, 1991), S. schlegeli (Kim et al., 2001) and Zeuxapta seriolae killing amberjacks Seriola dumerili (Montero et al., 2004).

The First Record of Two Polyopisthocotylean Monogeneans on Gill of the … 9 Remarks: According to Jean-Lou Justine (Personal communication), this species resembles Vallisiopsis contorta Subhapradha, 1951 from S. commersonii from Madagascar, as redescribed by Euzet and Razarihelisoa (1959). S. commersonii is now considered a synonym of Sphyraena barracuda according to Froese and Pauly (2012). The characteristic description of the present specimens is conspecific with the type specimens of V.

  • Parasites of Coral Reef Fish: How Much Do We Know? with a Bibliography of Fish Parasites in New Caledonia
    Belg. J. Zool., 140 (Suppl.): 155-190 July 2010 Parasites of coral reef fish: how much do we know? With a bibliography of fish parasites in New Caledonia Jean-Lou Justine (1) UMR 7138 Systématique, Adaptation, Évolution, Muséum National d’Histoire Naturelle, 57, rue Cuvier, F-75321 Paris Cedex 05, France (2) Aquarium des lagons, B.P. 8185, 98807 Nouméa, Nouvelle-Calédonie Corresponding author: Jean-Lou Justine; e-mail: [email protected] ABSTRACT. A compilation of 107 references dealing with fish parasites in New Caledonia permitted the production of a parasite-host list and a host-parasite list. The lists include Turbellaria, Monopisthocotylea, Polyopisthocotylea, Digenea, Cestoda, Nematoda, Copepoda, Isopoda, Acanthocephala and Hirudinea, with 580 host-parasite combinations, corresponding with more than 370 species of parasites. Protozoa are not included. Platyhelminthes are the major group, with 239 species, including 98 monopisthocotylean monogeneans and 105 digeneans. Copepods include 61 records, and nematodes include 41 records. The list of fish recorded with parasites includes 195 species, in which most (ca. 170 species) are coral reef associated, the rest being a few deep-sea, pelagic or freshwater fishes. The serranids, lethrinids and lutjanids are the most commonly represented fish families. Although a list of published records does not provide a reliable estimate of biodiversity because of the important bias in publications being mainly in the domain of interest of the authors, it provides a basis to compare parasite biodiversity with other localities, and especially with other coral reefs. The present list is probably the most complete published account of parasite biodiversity of coral reef fishes.

  • SEM Study of Diplozoon Kashmirensis (Monogenea, Polyopisthocotylea) from Crucian Carp, Carassius Carassius
    SEM study of Diplozoon kashmirensis (Monogenea, Polyopisthocotylea) from Crucian Carp, Carassius carassius Shabina Shamim, Fayaz Ahmad Department of Zoology, University of Kashmir, Srinagar – 190 006, Kashmir, J&K, India ABSTRACT Using Scanning Electron Microscopy the external morphology of the helminth parasite Diplozoon kashmirensis (Monogenea, Diplozoidae) from the fish Carassius carassius is described herein for the first time. The present study is a part of the parasitological work carried out on the fishes of Jammu and Kashmir. These fish helminthes are ectoparasites, blood feeding found on gills of fishes. They have extraordinary body architecture due to their unique sexual behavior in which two larval worms fuse together permanently resulting in the transformation of one X shaped duplex individual. Oral sucker of the prohaptor has a partition giving it a paired appearance. The opisthohaptor present on hind body contains four pairs of clamps on each haptor of the pair, a pair of hooks and a concave terminal end. Body is composed of tegmental folds to help the worms in fixing to the gills. This type of strategy adapted for parasitic life in which two individuals permanently fuse into a single hermaphrodite individual without any need to search for mating partner and presence of highly sophisticated attachment structures, shows highest type of specialization of diplozoid monogeneans. In this study we used SEM to examine the surface topography of Diplozoon kashmiriensis, thereby broadening our existing knowledge of surface morphology of fish helminthes. Key Words – Carassius carassius, Diplozoon kashmirensis, Monogenea, Opisthohaptor, SEM. I INTRODUCTION Monogenea is one of the largest classes within the phylum Platyhelminthes and they usually possess anterior and posterior attachment apparatus that are used for settlement, feeding, locomotion and transfer from host to host [1, 2, 3].

Three gastrocotylid genera share similar morphology and anatomy but are distinguished by this character: Pseudaxine Parona & Perugia, 1890 has no vagina, Allogastrocotyle Nasir & Fuentes Zambrano, 1983 has two vaginae, and Pseudaxinoides Lebedev, 1968 has multiple vaginae. In the course of a study of Pseudaxine trachuri Parona & Perugia 1890, we found specimens with structures resembling “multiple vaginae”; we compared them with specimens without vaginae in terms of both morphology and molecular characterisitics (COI barcode), and found that they belonged to the same species.
