“…Seasonality and vertical distribution in egg-laying activity of A. foliaceus in natural conditions have been demonstrated by Harrison et al (2006). In contrast, no work has been conducted on the small-scale temporal distribution of egg-laying by A. foliaceus, in particular with regards to diel variation in egg-laying activity.…”

Removal of deposited eggs could be a useful control strategy for the damaging fish ectoparasite Argulus foliaceus, but focused control requires knowledge of egg-laying patterns. Here, we investigated diel changes in the egg-laying behaviour of a natural population of A. foliaceus. Data were collected from 17−28 May 2004. Days were divided into 3 time periods: 06:00−14:00, 14:00− 22:00 and 22:00−06:00 h. Significantly more egg clutches were laid from 06:00−14:00 h than during the other 2 time periods, which were not significantly different from each other. Significantly more egg clutches per hour were laid during hours of daylight as compared to hours of darkness. Significantly more egg clutches were laid in the top 1 m of the water column than at the bottom, and this was consistent throughout all 3 time periods. It is suggested that the increase in egg-laying activity during daylight hours may be due to a higher motivation to search for hosts during the night and an increased ability to locate silhouetted egg-laying sites during the day. These data can provide information useful for egg removal and control strategies.KEY WORDS: Argulus foliaceus · Freshwater fish louse · Egg-laying · Diel variation · Depth · Parasite · Rainbow trout Resale or republication not permitted without written consent of the publisherDis Aquat Org 78: [169][170][171][172] 2007 could be found on the topic (Kimura 1970), and this was in relation to another species of argulid, Argulus japonicus, a common parasite of cultured carp Cyprinus carpio. This species has recently been introduced into Britain with goldfish as a result of the ornamental fish trade from Southeast Asia (Rushton-Mellor 1992). Kimura (1970) notes that, in experimental conditions, egg deposition of A. japonicus was observed exclusively under dark conditions. He concludes that this species of freshwater fish louse is therefore considered to lay its eggs mostly during the night in fish farms, although this was not tested directly.Control strategies for Argulus spp. based on removal of deposited eggs have yielded some success (Bauer 1959, Shimura 1983, Gault et al. 2002. Floating wooden boards have been used in Eastern Europe as a substrate for A. foliaceus egg-laying (Bauer 1959), whilst transparent acrylic plates have been adopted in Japan to facilitate removal of A. coregoni egg clutches from fish-rearing ponds (Shimura 1983).

“…It caused pathological changes due to direct tissue damage and secondary infections (Al-Dulaimi 2010). It feeds by piercing the skin of the host, with heavy infestations leading to serious skin damage, stress and death (Harrison et al 2006). Feeding can take place on the skin or in the gills of the fish causing intense irritation and tissue damage (Al-Dulaimi 2010).…”

The genus Argulus (Crustacea: Branchiura), or fish louse, are common parasites of freshwater fish. This parasite have a direct life cycles and mature females leave the host and lay several hundred eggs on vegetation and various objects in the water. It caused pathological changes due to direct tissue damage and secondary infections. Besides the damage and stress caused by Argulus itself, one of the main worries for fish producers are the associated secondary infestations and infections that can result from infestation with this ecto-parasite. From 300 samples, only 20 (6.67 %) samples were infested with this parasite and 280 (93.33 %) not infested. In the present study, Argulus foliaceus was reported on goldfish and Koi which this was first recorded in Kerman, southeast of Iran. According to the presented study, it is clear that A. foliaceus can act as a potential risk factor for natural ecosystems and native fish population of Iran and other countries, that should be mentioned to prevent the burst of new parasitic fauna to Iran and different countries as well as stop direct economic losses caused by mortality derived from infestation with this ecto-parasite.
