“…Similar observations are available for A. coregeni, A. foliaceus, and A. japonicus (Shafir and Oldewage 1992;Harrison et al 2006;Bandilla et al 2007). Although the age-specific survivorship was similar for male and female A. bengalensis, the life expectancy, a predictor of longevity of individuals, was significantly different (Figure 3), indicating possible sex-specific differences in investment towards reproduction and fitness.…”

“…is a useful indicator of parasite-fish host interactions and the level of impact on the host species. Empirical evidence suggests that the infestation and impact on different fish hosts by A. foliaceus (Pasternak et al 2000), A. canadensis Fitzgerald 1989a, 1989b), A. coregoni (Bandilla et al 2004;Pasternak et al 2004aPasternak et al , 2004b, and A. japonicus (Shafir and Oldewage 1992;Harrison et al 2006;Bandilla et al 2007) vary with their life history features. The management of these parasites in field conditions can be enhanced if the life history parameters are evaluated so as to retrieve the key features in maintenance and perpetuation of the parasite population.…”

The Life table features and the fecundity schedule of the fish louse Argulus bengalensis (Branchiura: Argulidae) were estimated under laboratory conditions using Cirrhinus mrigala as the model host. The cohort-based Life table revealed that survival of A. bengalensis declines as a function of age. Life expectancy was observed to be 34 days for a newly emerged adult. The mean number of eggs produced per egg strip was 86 (±8.89 S.E.). The sex ratio 2:1 was biased towards males. The net reproductive rate (R 0 ) varied between 50 and 487 while the cohort generation time (T c ) ranged between 24 and 26 days. The intrinsic rate of increase (r) was 0.14-0.23, while the finite rate of increase (λ) remained between 1.16 and 1.28. The Life table features and the fecundity schedule of A. bengalensis are comparable with congenerics of temperate regions. Early reproduction (between 21 and 23 days) and an extended postreproductive phase (47 days) of females are characteristic of A. bengalensis and a reflection for survival under uncertain conditions and a parasitic mode of life.

“…It was also found that the parasite preferred larger fish to smaller hosts (Webb 2008). According to Shafir and Oldewage (1992), peaks in the population of A. japonicus corresponded with reduced water levels as well as high temperatures. Sahoo et al (2013a) found optimum temperature of 28°C for the development of the eggs of A. siamensis into the infective metanaupliar stage.…”

Argulus, an obligate macroectoparasite, infests a wide range of fishes causing severe economic loss to aquaculture industry. The application of chemotherapeutants is the most common approach to combat argulosis. But it is very expensive and has a range of negative impacts on the host and environment. An alternative to the extensive use of chemotherapeutics is to restrict Argulus infestation by adopting a range of biosecurity and quarantine measures. However, before adopting these measures it is essential to adequately understand the complex interaction among the host, parasite and environment, in order to identify key factors affecting parasite dynamics and to formulate a possible management strategy. Epidemiology provides key tools to advance our understanding of diseases and allows bringing convergence in controlling the disease. Compared to terrestrial diseases, relatively few epidemiological studies have been conducted to investigate aquatic animal diseases. For Argulus spp., the complex real-world dynamics of transmission, reproduction and the host specificity and the role of these parasites as a vector for various pathogens are very complex to develop an effective epidemiological framework. This review principally focuses on the application of epidemiological concepts, providing insights about the sampling frame, commenting upon the use of simple deterministic susceptible-infectedremoved models and examines the determinants of transmission and spread of argulosis. Further, this paper describes the risk factors associated with Argulus infestation and the importance of risk analysis in intervention against its epizootics. Overall, this review is intended to highlight the need for development of a more extensive epidemiological approach to combat argulosis in aquaculture.Saurav Kumar and T. Sathish Kumar have contributed equally to this work.
