The sampling was conducted in Aceh Singkil, Aceh Jaya and Aceh Besar Districts from August to September 2016 and January 2017. Twenty-two samples from Aceh Singkil, one sample from Aceh Jaya, and 23 samples from Aceh Besar were analyzed for gastrointestinal worms. Two species of worms were found in the gastrointestinal tract of fish samples, namely, Anisakis sp. and Procamallanus sp. Anisakis sp. was found in the stomach of the eel sample from Aceh Singkil, while Procamallanus sp. was found in the intestine of the eel samples from Aceh Jaya. No fish samples from Aceh Besar were infested with nematode. Key words: Anisakis, Indonesia, nematode, Procamallanus, shortfin eel Philipp. J. Vet. Med., 55(1): 59-64, 2018 INTRODUCTION Eels of the genus Anguilla are widely found Unfortunately, several species of eels are throughout the world (Arai and Wong, 2016). threatened by overfishing and habitat loss According to Miller and Tsukamoto (2004), resulting in decrease of glass eel production there are 19 species of eels worldwide. Thirteen (Pujolar et al., 2007; Silfvergrip, 2009). species of eels are reported in tropical regions Information on the distribution and migration (Watanabe et al., 2009); of these, seven species of tropical shortfin eels A. bicolor bicolor and are found in Indonesian waters (Sugeha et al., A. bicolor pacifica have been reported by Arai 2006). Based on biometric characteristics, two et al. (1999), Sugeha and Suhartati (2008), and species of eels have been reported from Aceh Muchlisin et al. (2016); while genetic studies waters, Indonesia: Anguilla bicolor and A. have been conducted by Tanaka et al. (2014) marmorata (Muchlisin and Siti-Azizah, 2009). and Muchlisin et al. (2017). However, no Of the two species, the Indonesian shortfin eel report on parasites, particulary on nematode A. bicolor is the most abundant and distributed infestation in Indonesian shortfin eelA. bicolor widely in Aceh waters (Muchlisin et al., 2017). from Indonesian waters, is available. Eels are catadromous fishes; they migrate The world eels market is very promising. between inland or coastal growth habitats Japan needs about 130,000 tons of eels per and spawn offshore (Arai and Wong, 2016). year, but only 21,000 tons (16.8%) can be met (KKP, 2011). In addition, the global market requires more than 268,000 tons of eels per *FOR CORRESPONDENCE: year (FAO, 2014). Presently, most of the eels (email: [email protected]) produced come from wild populations, and 60 MUCHLISIN et al. production is seasonally dependent. Therefore, on Hurst (1984), Moravec and Justine (2006) eel production has a very good potential for and Koinari et al. (2013). The prevalence and aquaculture business (Muchlisin, 2013). intensity of infection were calculated based The extensive culture of eels has been on Kabata (1985) as follows: prevalence = initiated in Indonesia, where the larvae (total infected fish/total examined fish) × 100; are collected from the wild (Affandi, 2005); intensity = total parasites/total infected fish. therefore, the eels are very susceptible to diseases and parasites harmful to humans. Tumbo et al. (2011) reported that the giant RESULTS AND DISCUSSION marbled eel A. marmorata from North Sulawesi, Indonesia, has been infested with Trichodina A total of 46 eels were examined for sp., Myxobolus sp. and Vorticella sp., while gastrointestinal nematode infestation.

    SCALE-DEPENDENT VARIATION IN MOLECULAR AND ECOLOGICAL PATTERNS OF INFECTION FOR ENDOHELMINTHS FROM CENTRARCHID FISHES BY KYLE E. LUTH A Dissertation Submitted to the Graduate Faculty of WAKE FOREST UNIVERSITY GRADAUTE SCHOOL OF ARTS AND SCIENCES in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Biology May 2016 Winston-Salem, North Carolina Approved By: Gerald W. Esch, Ph.D., Advisor Michael V. K. Sukhdeo, Ph.D., Chair T. Michael Anderson, Ph.D. Herman E. Eure, Ph.D. Erik C. Johnson, Ph.D. Clifford W. Zeyl, Ph.D. ACKNOWLEDGEMENTS First and foremost, I would like to thank my PI, Dr. Gerald Esch, for all of the insight, all of the discussions, all of the critiques (not criticisms) of my works, and for the rides to campus when the North Carolina weather decided to drop rain on my stubborn head. The numerous lively debates, exchanges of ideas, voicing of opinions (whether solicited or not), and unerring support, even in the face of my somewhat atypical balance of service work and dissertation work, will not soon be forgotten. I would also like to acknowledge and thank the former Master, and now Doctor, Michael Zimmermann; friend, lab mate, and collecting trip shotgun rider extraordinaire. Although his need of SPF 100 sunscreen often put our collecting trips over budget, I could not have asked for a more enjoyable, easy-going, and hard-working person to spend nearly 2 months and 25,000 miles of fishing filled days and raccoon, gnat, and entrail-filled nights. You are a welcome camping guest any time, especially if you do as good of a job attracting scorpions and ants to yourself (and away from me) as you did on our trips.

Half a century ago, the state of Hawai’i introduced the Bluestripe Snapper, Lutjanus kasmira, to O’ahu for fisheries enhancement. Today, this species shares an intestinal nematode parasite, Spirocamallanus istiblenni, with native Hawaiian fishes, raising the possibility that the introduced fish carried a parasite that has since spread to naı¨ve local hosts. Here, we employ a multidisciplinary approach, combining molecular, historical, and ecological data to confirm the alien status of S.

Anguillicoloides crassus is of particular importance, as it has recently spread from its endemic range in the Eastern Pacific to Europe and North America, where it poses a significant threat to new, naïve hosts such as the economic important eel species Anguilla anguilla and Anguilla rostrata. The Anguillicolidae are therefore all potentially invasive taxa, but the relationships of the described species remain unclear. Anguillicolidae is part of Spirurina, a diverse clade made up of only animal parasites, but placement of the family within Spirurina is based on limited data.

There is, however, presently no study conducted on the endoparasites infestation in these fishes. Therefore, the objectives of the present study were to identify endoparasitic worms and examine the intensity level in skipjack tuna K. pelamis from Sibolga waters. Sampling was conducted in Debora Private Fishing Port, Sibolga from 4th to 18th June 2019 and a total of 20 fish samples with weight ranged between 740 g and 1.200 g and length from 37.2 cm to 41.4 cm were analyzed in the study. The identification of the worm was conducted in the laboratory using a stereo microscope. The results showed seven species or genera of worms were found in the intestine and stomach of the fish with varying level of intensity and incidence. For example, Echinorhynchus sp. was found with 100% intestinal and 10% stomach incidences at a total intensity of 8.5; Acanthocephalus sp. with 25% intestinal incidence and 1.6 intensity, Rhadinorhynchus sp. with 25% intestinal and 5% stomach incidences, and 1.5 intensity; Leptorhynchoides sp.

ABSTRACT Nematodes are found in all substrata and sediment types with fairly large number of species that are of considerable ecological importance. Despite their simple body organization, they are the most complex forms with many metabolic and developmental processes comparable to higher taxa. Phylum Nematoda represents a diverse array of taxa present in subterranean environment. It is due to the formative constraints to which these individuals are exposed in the interstitial system of medium and coarse sediments that they show pertinent characteristic features to survive successfully in aquatic environments. They represent great degree of mor - phological adaptations including those associated with cuticle, sensilla, pseudocoelomic in - clusions, stoma, pharynx and tail. Their life cycles as well as development seem to be entrained to the environment type. Besides exhibiting feeding adaptations according to the substrata and sediment type and the kind of food available, the aquatic nematodes tend to wi - thstand various stresses by undergoing cryobiosis, osmobiosis, anoxybiosis as well as thio - biosis involving sulphide detoxification mechanism. KEY WORDS Adaptations; fresh water nematodes; marine nematodes; morphology; ecology; development. Received 24.01.2012; accepted 23.02.2012;

    Treating Fish for CAMALLANUS and Other NEMATODES by Diana Walstad December 2017

    From http://dianawalstad.com Treating Fish for CAMALLANUS and Other NEMATODES By Diana Walstad December 2017 I have dealt with Camallanus roundworms three times over the years. Each infestation started shortly after the purchase of new guppies. Around 1985, the worms first appeared in fancy guppies that I bought from the breeder. All my little home remedies failed, such as simply growing out the babies in a separate tank. Discouraged, I eventually tore down the tanks and stopped keeping fish for awhile. When I started up again with new guppies, my old nemesis reappeared in 1998. This time, I sought professional help.1 Diagnosis: The fish had Camallanus worms. The juvenile Camallanus worms dangling from the this catfish’s fish were primarily infected and their growth anus constantly release eggs and live larva into the tank. Transmission occurs when fish pick at the substrate and stunted. Treatment involved my preparing a ingest the wriggling larva. fishfood containing Fenbendazole, a potent When the adult worms are visible on the outside like wormer. The vets gave me a recipe and a this, it means the fish is heavily infested. (Many infected liquid solution of Fenbendazole. I prepared fish show no symptoms.) the medicated food according to instructions and fed it to the fish twice a day for a week and then repeated the treatment three weeks later. This worming procedure cured the fish permanently without problems. After a long sojourn raising other types of fish, I started back up again with guppies in 2017. I wasn’t all that surprised to see Camallanus worms in some of the new guppies.
