“…According to the monogenean reports from our study area, poor water quality, biofouling of cages and high stocking density were factors affecting the resistance of farmed fish to infections with these parasites. In addition, these reports revealed that monogenean infections on neighbouring farms and wild fish interactions could be potential route of transmission for these types of parasites on fish farms (Aryadi et al, 2019; Dewi et al, 2018; Leong & Wong, 1988; Lestari et al, 2020; Ogawa et al, 2006; Putri et al, 2020; Rückert et al, 2008; Truong et al, 2017; Wijaya et al, 2019; Yang et al, 2006).…”

According to the latest report of the Food and Agriculture Organization of the United Nations (FAO), global aquatic animal production grew on average 5.3% per year between 2001 and 2018. As of 2018, production was at 82.1 million tonnes (valued at USD 250.1 billion), and of this tonnage, around 9% (with a value of USD 35.4 billion) was reported to be from marine finfish production, which is predominantly in Asia, and mostly in East and Southeast Asia (De Silva & Phillips, 2007; FAO, 2020a).The most common form of marine fish farming in Asia is cage culture, and the most commonly farmed species include amberjack (Seriola spp.), cobia (Rachycentron canadum), pompano (Trachinotus ovatus) and different types of groupers (Epinephelus spp.) and snappers (Lutjanus spp.) (De Silva & Phillips, 2007). This type of aquaculture has been growing in Asia over the last decade due to an increasing demand for live fish in the restaurant trade in the People's Republic of China (PR China

Pseudorhabdosynochus suratthaniensis n. sp. is described from the gills of Cephalopholis argus; P. cephalopholi n. sp., from the gills of C. sonnerati; and P. samaesarnensis n. sp., from the gills of Epinephelus lanceolatus. These fish were all caught in the Gulf of Thailand. Pseudorhabdosynochus suratthaniensis n. sp. is distinguished from congeneric species by the structure of its sclerotized vagina, which has a wide sclerotized trumpet and a single large primary chamber, and by the number of rows of rodlets in each of its squamodiscs. Pseudorhabdosynochus cephalopholi n. sp. is also distinguished by the structure of its sclerotized vagina that, like the P. suratthaniensis n. sp., has a sclerotized trumpet, but it also has a long coiled or curved primary canal near its midlength, and a distal part with a primary chamber and a secondary chamber communicating with the primary chamber through a short secondary canal. In addition, P. cephalopholi n. sp. is distinguished by some sclerotized organs (ventral and dorsal hamuli, ventral bar, and quadriloculate organ) with different lengths, and by the number of rows of rodlets in each of its squamodiscs. Pseudorhabdosynochus samaesarnensis n. sp. is distinguished by its sclerotized vagina that has an anterior cup-shaped trumpet and a short straight or curved primary canal. For Thailand, these are the first species of Pseudorhabdosynochus described from species of Cephalopholis and the second species of Pseudorhabdosynochus described from Epinephelus.

“…The highest prevalence occurred on cantang grouper (Epinephelus fuscoguttatus-lanceolatus) in eastern coast of Pangandaran, Indonesia, which is about 66.6% (ectoparasite: Diplectanum) and in the traditional FNC is approximately 44.4% (Diplectanum) (Rostika et al, 2018). Moreover, the prevalence of ectoparasites also happened on fish with sizes in a range of 15-27.5 cm in the Mariculture Center of Lombok, West Nusa Tenggara, Indonesia, reaches 27.5% (ectoparasite: Monogenea with Neobenedenia girellae species with a size of 3.8-5.4 x 1.5-2.5 mm in length) attacking the surface of body or skin, eyes, dorsal and ventral fins (Dewi et al, 2018). The fish attacked by parasite Benedenia acanthopagri is about 25.78% causing an increasing respiratory disorder on opercular and surface movement, gulping atmosphere air, propelling mouth open, bleeding on the base of fin, peeling off on tail, tail fin, and dorsal area; demonstrating different ulcers on body parts, emerging gill blockage (Hassan et al, 2015).…”

“…Interviewing the fishermen in the research location (fish raisers) implies that the ectoparasites are still there every year event hough their emersion fluctuates, sometimes in a large quantity and at other times is lower than attack the reared fish. The highest intensity of ectoparasites occurred on the Cantang grouper (Epinephelus fuscoguttatuslanceolatus) in eastern coast of Pangandaran, Indonesia, which is about 2.9 (Ectoparasite: Diplectanum) and in the traditional FNC is about 2 individuals (Ectoparasite: Diplectanum) (Rostika et al, 2018 (Dewi et al, 2018). This research points out that the intensity of ectoparasites during this research is lower than other locations in Indonesia, however, an intensity of 1.5 is enough to disturb the cultured grouper activity causing many cultured fish died.…”

Ectoparasite Prevalences of Grouper Fish (Epinephelus fuscogutatus x Epinephelus polyphekadion) Cultured in Floating Net Cages

2020

Monitoring the health of the reared fish in a floating net cage (FNC) is often conducted by examining their ectoparasites. This study determines ectoparasite prevalences of grouper fish (Epinephelus fuscogutatus x E. polyphekadion). It was conducted in the waters surrounding Pongok Island, South Bangka Regency. The health examination of both fish and ectoparasites was carried out by applying simple random sampling during three periods, November 2016 (I), February 2017 (II) and May 2017 (III). Hydro-oceanography surveys were done every month during the three years. The grouper checkings (I, II and III) indicated the prevalences of ectoparasites in these periods were 43.3%, 8.8% and 13.5%, respectively. Fish death highly occurred in the period I, and the grouper survival rate at harvesting time was only 70% from initial seed stocking of 1,500 fish. The ectoparasite intensities during the research periods were 1.6, 1.6 and 1.5, respectively. This condition implies that every 10 groupers would potentially be attacked by at least 15-16 ectoparasites. A slow seawater current flow triggered the quick uplifting of the ectoparasites from the seafloor. The water condition at the FNC location in 2011 and 2017 was still under the quality standard. The ectoparasites were coming from the surrounding environment of the FNC location. It is inevitable that the fish culture management should focus on cleansing the ectoparasites attaching on the groupers, dusting the net cage clean, and arranging the harvest pattern on a particular month following the surrounding environmental condition to prevent ectoparasite attacks.
