“…2008). The bioaccumulation ability of L. intestinalis is higher in R. argentea , however, compared with tench ( Tinca tinca ) from Lakes Kovada (Tekin‐Özan & Kir 2005) and Beysher (Tekin‐Özan & Barlas 2008), both in Turkey. The bioaccumulation of Cd by L. intestinalis in R. argentea is lower than for another cestode ( Monobothrium wageneri ) and Bothriocephalus scorpii in Tinca tinca (Sures et al.…”

“…As this parasite is easy to identify, even in different hosts (Olson et al. 2000; Tekin‐Özan & Kir 2005; Tekin‐Özan & Barlas 2008), because of its high abundance and high prevalence, it should be considered as a biomonitor model and early warning sign for localized Pb, Cd and Cr pollution in waterbodies.…”

“…Cestodes currently affect a large number of fish species, and can survive in a wide range of varying environments (Jirsa et al. 2008; Tekin‐Özan & Barlas 2008). Further studies on systematically different parasites from different microhabitats, as well as from different environments, are required to evaluate the cestode–fish host association as a potential biomonitoring tool for heavy metal contamination.…”

Use of some fish parasites as bioindicators of heavy metal pollution has been demonstrated as a promising approach because of their capacity to bioconcentrate such elements. This study evaluated the effects of a cestode parasite, Ligula intestinalis, on the accumulation of lead (Pb), cadmium (Cd), chromium (Cr) and copper (Cu) in the cyprinid fish, Rastreneobola argentea, in Lake Victoria, Kenya. This L. intestinalis ⁄ R. argentea model also was assessed as a bioindicator system for heavy metal contamination in the lake. Samples of 125 fish, 63 parasites, water and sediments were collected at four sites in the Kenya portion of the Lake Victoria basin characterized by variable heavy metal concentrations, for ICP-OES element analysis. The concentration of all four heavy metals in the fish and parasite samples exhibited site-specific variations relative to the metal concentrations in the water. The Pb, Cr and Cd concentrations in the L. intestinalis were higher than in the fish samples by a factor 11, 18 and 14 respectively, whereas the Cu concentration in L. intestinalis was increased by a factor of 2.5, relative to the Cu concentration in fish. The Pb, Cd and Cr concentrations in the parasite body increased, relative to their concentrations in fish samples, suggesting in the bioaccumulation of these metals by the parasite. The Cu concentration in the fish parasite decreased, relative to increased Cu levels in the fish. This finding was interpreted as being a competition for these elements between the parasite and its fish host. Moreover, the increased Cd and Cr levels in the fish were significantly influenced by the increased abundance of the parasites in the abdominal cavity of the fish samples. Based on the results of this study, the L. intestinalis ⁄ R. argentea system is proposed as a promising bioindicator model for evaluating environmental Pb, Cd and Cr concentrations where these species occur.

“…They hypothesised that this indicated that accumulation of heavy metals in the parasite was a gradual and long-term process which probably occurred during the growing phase of the parasite in the fish host. More recent studies by Tekin-Ozan and co-workers (Tekin-Ozan and Kir, , 2008Tekin-Ozan and Barlas, 2008), utilising Ligula and tench (Tinca tinca), have extended the greater bio-accummulation by the plerocercoid to a more extensive range of heavy metals and speculate that if the parasite reflects the amount of heavy metal contaminants in the water and sediments, it may provide reliable data about pollution in water bodies. Whilst this is perhaps debatable, the value of the association of the plerocercoid with heavy metals probably lies in the size of the parasite which may assist in the elucidation of how parasites can bioaccumulate pollutants with no apparent ill-effects on their biology.…”

S U M M A R YSince its use as a model to study metazoan parasite culture and in vitro development, the plerocercoid of the tapeworm, Ligula intestinalis, has served as a useful scientific tool to study a range of biological factors, particularly within its fish intermediate host. From the extensive long-term ecological studies on the interactions between the parasite and cyprinid hosts, to the recent advances made using molecular technology on parasite diversity and speciation, studies on the parasite have, over the last 60 years, led to significant advances in knowledge on host-parasite interactions. The parasite has served as a useful model to study pollution, immunology and parasite ecology and genetics, as well has being the archetypal endocrine disruptor.

The aquatic environment represents the final repository for many human-generated pollutants associated with anthropogenic activities. The quality of natural freshwater systems is easily disrupted by the introduction of pollutants from urban, industrial and agricultural processes. To assess the extent of chemical perturbation and associated environmental degradation, physico-chemical parameters have been monitored in conjunction with biota in numerous biological monitoring protocols. Most studies incorporating organisms into such approaches have focussed on fish and macroinvertebrates. More recently, interest in the ecology of parasites in relation to environmental monitoring has indicated that these organisms are sensitive towards the quality of the macroenvironment. Variable responses towards exposure to pollution have been identified at the population and component community level of a number of parasites. Furthermore, such responses have been found to differ with the type of pollutant and the lifestyle of the parasite. Generally, endoparasite infection levels have been shown to become elevated in relation to poorer water quality conditions, while ectoparasites are more sensitive, and exposure to contaminated environments resulted in a decline in ectoparasite infections. Furthermore, endoparasites have been found to be suitable accumulation indicators for monitoring levels of several trace elements and metals in the environment. The ability of these organisms to accumulate metals has further been observed to be of benefit to the host, resulting in decreased somatic metal levels in infected hosts. These trends have similarly been found for host-parasite models in African freshwater environments, but such analyses are comparatively sparse compared to other countries. Recently, studies on diplozoids from two freshwater systems have indicated that exposure to poorer water quality resulted in decreased infections. In the Vaal River, the poor water quality resulted in the extinction of the parasite from a site below the Vaal River Barrage. Laboratory exposures have further indicated that oncomiracidia of Paradiplozoon ichthyoxanthon are sensitive to exposure to dissolved aluminium. Overall, parasites from African freshwater and marine ecosystems have merit as effect and accumulation indicators; however, more research is required to detail the effects of exposure on sensitive biological processes within these organisms.
