“…After infection, Asian tapeworms are potentially fatal to multiple age-classes of fishes either through direct mortality or creating diseased and weakened individuals. In the case of endangered desert fishes of the United States, it is believed that bait introductions of infected non-native red shiners (Notropis lutrensis) contributed to the infestation of many native populations (Heckmann et al 1987). The rapid life cycle and nonhost specificity of this parasite allow it to spread very quickly, making it difficult to control.…”

“…The Asian fish tapeworm is established on six continents and currently infects over 100 species of fish (Salgado-Maldonado and Pineda-López 2003). It is established in the USA, Canada, and Mexico (Heckmann and Deacon 1987;Brouder and Hoffnagle 1997;Ward 2005;Choudhury et al 2006;Bean et al 2007), with transfer into new drainages likely attributable to baitfish introductions (Heckmann et al 1993;Choudhury et al 2004).…”

Recent collections of the Asian fish tapeworm Bothriocephalus acheilognathi in the Rio Grande have raised concern about the potential impacts on Rio Grande endemic and imperiled fishes. The objectives of this study were to determine distribution and definitive hosts of the Asian fish tapeworm within the Rio Grande drainage and to quantify occurrences and abundances. In total, 1,992 fish spanning 11 families were collected and examined for Asian fish tapeworms in the Rio Grande and the Pecos and Devils rivers. The parasite was collected from red shiners Cyprinella lutrensis, Tamaulipas shiners Notropis braytoni, sand shiners N. stramineus, river carpsuckers Carpiodes carpio, plains killifish Fundulus zebrinus, western mosquitofish Gambusia affinis, blue suckers Cycleptus elongatus, blacktail shiners Cyprinella venusta, proserpine shiners Cyprinella proserpina, and Manantial roundnose minnow Dionda argentosa, with the latter four species being new host records. Monthly collections of red shiners from Big Bend National Park exhibited prevalence levels above 15% in January-March and December and below 10% during April-June and October. With over 50% of the Rio Grande icthyofauna in Texas considered imperiled, the occurrence and pathological effects of the Asian fish tapeworm in combination with reduced water quantity and quality and increased habitat fragmentation are of concern for these taxa.

“…The Asian tapeworm Bothriocephalus acheilognathi is found in the intestines of freshwater fishes (usually cyprinids) throughout the world (Bauer et al 1969;Bauer and Hoffman 1976;Hoole and Nisan 1994). In the USA, this tapeworm was first found in cultured cyprinids in 1975 and now occurs in both wild and commercial fish stocks in several states (Hoffman 1976;Heckmann et al 1987;Choudhury et al 2004). The Asian tapeworm has been reported to affect fish by slowing growth, lowering the ability to withstand harvesting procedures, shortening the life span, and occasionally causing death (Mitchell 2003).…”

Praziquantel is an effective anthelmintic treatment that has been used in dogs Canis lupus familiaris and cats Felis catus. It has also been used successfully against tapeworms and trematodes in fish. This study tested the efficacy of praziquantel bath treatments (6, 12, or 24 h) at various concentrations (0.187, 0.375, 0.75, 1.5, 3.0, 6.0, 9.0, and 12.0 mg of praziquantel/L of water) for controlling natural infestations of Asian tapeworms Bothriocephalus acheilognathi in grass carp Ctenopharyngodon idella (60-100% of the fish were infested). Treatments either were given as a single application or were applied twice (3 d apart) at fish densities of 60 or 120 g/L. The objective of the study was to find a treatment that would completely eliminate Asian tapeworms from all infested fish, as a number of states now require imported fish to be completely free of this parasite. Most of the praziquantel treatments reduced the percentage containing Asian tapeworms. Single, 24-h bath treatments at praziquantel concentrations of 0.75 mg/L or higher applied to fish held at a density of 60 g/L were the only treatments that completely eliminated Asian tapeworms. Raising the fish density from 60 to 120 g/L affected treatment success; the 24-h, 0.75-mg/L praziquantel treatment at the higher fish density did not completely eliminate Asian tapeworms (prevalence ¼ 15%). A 12-h, 1.5-mg/L praziquantel treatment applied twice to fish held at a density of 60 g/L resulted in low Asian tapeworm prevalence (3.3%).
