In the Centre, some trematode species belonging to the family Strigeidae were found in freshwater fish ( Poddubnaya et al, 2010 ); whereas species of the families Aspidogastridae, Bivesiculidae, Callodistomidae, Cryptogonimidae, Didymozoidae, Haploporidae, Hemiuridae, Lecithasteridae, Lecithodendriidae, Microphallidae, Opecoelidae and Philophthalmidae were reported in brackish and marine water fish ( Hai, 2009 ; Glenn et al, 2010 ; Te et al, 2010 ; Vo et al, 2011 ; Tuan et al, 2015 ; Zhokhov et al, 2018 ; Atopkin et al, 2020 ). In the South, some digeneans of the families Strigeidae, Cryptogonimidae, Lissorchiidae were found in freshwater fish ( Sokolov et al, 2020 ; Thu et al, 2007 ; Sokolov and Gordeev, 2019 ); while no trematodes were reported in brackish and marine fish.…”

In Vietnam, fisheries play a key role in the national economy. Helminth infections in fish have a major impact on public health and sustainable fish production. A comprehensive summary of the recent knowledge on fish helminths is important to understand the distribution of parasites in the country, and to design effective control measures. Therefore, a systematic review was conducted, collecting available literature published between January 2004 and October 2020. A total of 108 eligible records were retrieved reporting 268 helminth species, among which are digeneans, monogeneans, cestodes, nematodes and acanthocephalans. Some helminths were identified with zoonotic potential, such as, the heterophyids, opisthorchiids, the nematodes Gnathostoma spinigerum , Anisakis sp. and Capillaria spp. and the cestode Hysterothylacium ; and with highly pathogenic potential, such as, the monogeneans of Capsalidae, Diplectanidae and Gyrodactylidae, the nematodes Philometra and Camallanidae, the tapeworm Schyzocotyle acheilognathi, the acanthocephalans Neoechinorhynchus and Acanthocephalus. Overall, these studies only covered about nine percent of the more than 2400 fish species occurring in the waters of Vietnam. Considering the expansion of the aquaculture sector as a part of the national economic development strategy, it is important to expand the research to cover the helminth fauna of all fish species, to assess their potential zoonotic and fish health impacts.

“…In the cleaner wrasse, L dimidiatus , a longer striped pattern is known to attract comparatively more fish [49]. Zhokhov et al [50] reported that 11 parasite species (two species of copepods, six digeneans, two nematodes and one acanthocephalan) have been found in anemonefish in the South China Sea. Thus, the presence of cleaner fish, which feed on body surface parasites, should be beneficial to anemonefish.…”

Colour patterns influence symbiosis and competition in the anemonefish–host anemone symbiosis system

2022

Colour patterns in fish are often used as an important medium for communication. Anemonefish, characterized by specific patterns of white bars, inhabit host anemones and defend the area around an anemone as their territory. The host anemone is used not only by the anemonefish, but also by other fish species that use anemones as temporary shelters. Anemonefish may be able to identify potential competitors by their colour patterns. We first examined the colour patterns of fish using host anemones inhabited by Amphiprion ocellaris as shelter and compared them with the patterns of fish using surrounding scleractinian corals. There were no fish with bars sheltering in host anemones, although many fish with bars were found in surrounding corals. Next, two fish models, one with white bars and the other with white stripes on a black background, were presented to an A. ocellaris colony. The duration of aggressive behaviour towards the bar model was significantly longer than that towards the stripe model. We conclude that differences in aggressive behaviour by the anemonefish possibly select the colour patterns of cohabiting fish. This study indicates that colour patterns may influence not only intraspecific interactions but also interspecific interactions in coral reef ecosystems.

“…The host anemone can act as both a shelter and a feeding site for some species of fish, and it can be difficult to separate the two purposes. As 11 parasite species (2 species of copepods, 2 digeneans, 2 nematodes and 1 acanthocephalan) have been found in anemonefish (Zhokhov et al, 2019), the presence of cleaner fish, which feed on body surface parasites, can be considered as beneficial for anemonefish. Host anemones, anemonefish, cleaner fish and other fish species may interact with each other in complex ways.…”

Large host anemones can be shelters of a diverse assemblage of fish species, not just anemonefish

The mutualistic relationships between anemonefish (Amphiprion; Pomacentridae) and host sea anemones are well known, but host anemones are also used as shelter by damselfish (Pomacentridae), wrasses (Labridae) and cardinalfish (Apogonidae).The threespot dascyllus Dascyllus trimaculatus (Pomacentridae) is known to live on or near host anemones in their immature phase. Nonetheless, detailed studies on the use of host anemones by other fish species have not yet been conducted. To understand the factors that influence the use of host anemones by other fish species, this study investigated the fish biota around host anemones in the Ryukyu Archipelago.Other than Amphiprion spp. and D. trimaculatus, 10 additional species of fish (9 species of damselfish and 1 species of cardinalfish) were confirmed to temporarily use host anemones as shelter, and five species of wrasse including Labroides dimidiatus came to clean anemonefish. Logistic regression analyses (independent variable: presence or absence of other species of fish; dependent variables: anemonefish aggressiveness, size of host anemone, number of D. trimaculatus) indicated that the size of host anemones is important for the presence of fish, both in species using the anemone as temporary shelter and in cleaner species. Large host anemones can provide shelter and food resources for other species of coral reef fish as well as for anemonefish.
