“…Argulus parasites are morphologically broad, oval, and flat on both sides (Radkhah 2017) covered by chi-tosan carapace (Figure 1). They have a part called the maxilla, which usually acts as a powerful suctorial organ and is adapted for suction during feeding (Poly 2005).…”

“…Parasitic infections have been raised as one of the most important problems in the aquaculture sector (Radkhah 2017) that can lead to reduced growth and vital activity of the fish and even its death. The outbreak of ectoparasites not only directly leads to the death of fish, but also impairs their growth and reproduction and predisposes them to bacterial and fungal infections (Pulkkinen et al 2010;Lafferty et al 2015;Assefa and Abunna 2018).…”

“…Fish lice are of special economic importance because they cause instability, discoloration, deformation of the body, as well as reduced growth and body weight of fish (Mirzaei and Khovand 2015;Shinn et al 2015). Given that ornamental fish pathogens are spreading rapidly around the world due to their commercial benefits, hence, control of infectious diseases of aquarium fish is very im-portant for risk analysis and precautionary measures (Jalali 1997;Radkhah 2017).…”

“…Due to the fact that Iranian ornamental fish are mainly imported from Asian countries such as Malaysia, Thailand, Indonesia and Vietnam (Radkhah and Eagderi 2018), so it is possible to transfer parasitic species, especially Argulus, to the country (Radkhah 2017). Because many of these ornamental fish are inadvertently released into the wild by locals (Radkhah et al 2017), it is also possible to transmit these parasitic agents to natural ecosystems and to spread the disease to endemic fish (Guerrero 2014).…”

Farming and trading of aquarium fish has been considered a popular pastime in the world. Most of Iran's aquarium fish are imported from Asian countries including Indonesia, Malaysia, Thailand and Vietnam. Fish lice (Argulus) is known as one of the most important and common ectoparasites in ornamental fish. Reports indicate that these parasites have been observed in ornamental fish imported to Iran (e.g goldfish Carassius auratus and koi carp Cyprinus carpio). Today, due to mismanagement of some ornamental fish breeding centres in Iran, aquarium fish species such as goldfish may have escaped into the natural waters which increase the risk of transmitting pathogens to native fish. The present work was performed to investigate the outbreak of an ectoparasite Argulus in two ornamental fish of Iran and also to evaluate the possibility of transmission of Argulus to inland freshwater fishes of Iran.

“…Here, we examined the impact of temperature on one of the most common Eurasian freshwater fish lice, Argulus foliaceus (see Radkhah 2017), before infection, during establishment and post-infection. Specifically, we aimed to identify changes in parasite hatching, growth and survival on and off the host.…”

With expanding human populations, the food sector has faced constant pressure to sustainably expand and meet global production demands. In aquaculture this frequently manifests in an animal welfare crisis, with fish increasingly farmed under high production, high stress conditions. These intense environments can result in fish stocks having a high susceptibility to infection, with parasites and associated disease one of the main factors limiting industry growth. Prediction of infection dynamics is key to preventative treatment and mitigation. Considering the climatic and technology driven changes facing aquaculture, an understanding of how parasites react across a spectrum of conditions is required. Here we assessed the impact of temperature, infection density and host species on the life history traits of Argulus foliaceus, a common palearctic fish louse, representative of a parasite group problematic in freshwater aquaculture and fisheries worldwide. Temperature significantly affected development, growth and survival; parasites hatched and developed faster at higher temperatures, but also experienced shorter lifespans when maintained off the host. At high temperatures, these parasites will likely experience a short generation time as their life history traits are completed more rapidly. A. foliaceus additionally grew faster on natural hosts and at lower infection densities. Ultimately such results contribute to prediction of population dynamics, aiding development of effective control to improve animal welfare and reduce industry loss.

Abstract. Amriana, Sari KD, Sriwulan, Anshary H. 2022. Evaluation of Argulus indicus on striped snakehead (Channa striata) in Towuti Lake, South Sulawesi, Indonesia. Biodiversitas 23: 1355-1362. Fish parasites are frequently present in wild freshwater fish populations, but data are limited on their distribution and impacts. This research aimed to investigate the severity of parasitic Argulus infestation on striped snakeheads (Channa striata) caught in Towuti Lake based on prevalence, intensity, and the bacteria associated with Argulus parasitizing C. striata. The research was conducted from March 2018 to February 2019 at Towuti Lake, South Sulawesi Province, Indonesia. Striped snakehead samples were captured using fish traps and gillnets. Samples of bacteria associated with Argulus were collected from four striped snakeheads (three infested and one non-infested control). Bacteria from Argulus attachment sites were identified through Vitek-2 Compact biochemical tests. Argulus prevalence on striped snakeheads was in the range 73.3-96.7%, with a mean intensity range of 2.18-14.43 and mean abundance 1.67-13.47. Water quality parameters measured in Towuti Lake remained within the Indonesian standards for freshwater fish habitat. The bacteria in striped snakehead mucus comprised two species in control (Staphylococcus xylosus, Pantoea sp.) and seven species in the parasitized fish (Micrococcus luteus, Bacillus mycoides, Acinetobacter baumannii, Sphingomonas paucimobilis, Pantoea sp., Aerococcus viridans, Staphylococcus arlettae). This study found a very high prevalence of striped snakehead infestation with parasitic A. indicus at low to medium intensity levels. The study also showed that A. indicus infestation was accompanied by and likely stimulated pathogenic bacteria, which can cause skin infections in fish. Therefore, A. indicus could be considered a threat to striped snakehead populations in Towuti Lake.
