“…In Jacareí and Timbó, 87.1% (27/31) and 88% (44/55) of fish were infected with monogeneans, respectively. These flatworms have already been reported in different ornamental freshwater fish from Brazil (Tavares- Dias et al, 2009Dias et al, , 2010Florindo et al, 2017a;Santos et al, 2017;Hoshino et al, 2018). They have a direct life cycle and can cause respiratory disease when infecting gills, or scale loss may occur if the parasite is attached to the skin.…”

This study aimed to search parasites in 333 ornamental fish from five Brazilian states (Ceará, Minas Gerais, São Paulo, Paraná and Santa Catarina). Fish were sent from eight farms located in the municipalities of Fortaleza, Patrocínio do Muriaé, São Francisco do Glória, Cascavel, Timbó, Iguape, Jacareí and Mairinque. All fish received anesthesia earlier to euthanasia procedures. After the search for parasites, it was verified that 70.6% (235/333) of fishes were infected by at least one type of parasite, being 12 types of parasites identified: monogeneans, digenean metacercariae, cestodes, nematodes, Lernaea cyprinacea, trichodinids, Piscinoodinium pillulare, Ichthyophthirius multifiliis, diplomonad flagellates, Ichthyobodo sp., Chilodonella sp., and Tetrahymena sp. The proportion of infected fishes among the farms is compared through statistical tests, besides, animal handling adopted in each farm is also discussed. The importance of ensuring fish health in order to make the ornamental freshwater fish industry economically viable and reduce losses in production is highlighted.

“…The freshwater angelfish is one of the most traded species of ornamental fish, however, there is a lack of scientific descriptions of the diseases that affect these animals (Gallani et al, 2016). Previous studies describe parasitic infestations caused by parasite (Florindo et al, 2017) and environmental factors are generally the main causes of stress in fish (Perera et al, 2023) decreasing their resistance to adverse factors (Ribeiro et al, 2023).…”

This study evaluated the growth performance and parasite load of angelfish juveniles Pterophyllum scalare kept at different stocking densities using two rearing systems. The experiment was conducted in a factorial design (4x2) with four stocking densities (0.1, 0.4, 0.7, and 1.0 g/L), two type of aquarium tanks (glass and ceramic aquariums), and four replicates. The experiment lasted 60 days using 148 juvenile fish (3.05 ± 0.09 g) randomly placed in 32 aquariums (50 L) equipped with filters and aeration. All fish received two meals a day ad libitum (8:00 and 16:00). Water quality parameters such as temperature, dissolved oxygen, pH, and total ammonia were measured. At the end of the experiment, all fish were measured and weighed to determine growth performance and then subjected to parasitological analysis. The data were analyzed with a two-way ANOVA with post-hoc Tukey test (p<0.05). No effects on growth performance at different stocking densities were observed. However, there was an increase in Capillaria pterophylli infestation in the high stocking density within ceramic aquariums. Thus, this study recommends the use of 1.0 g/L for the intensive aquaculture system of freshwater angelfish, and applying cleaning management to avoid parasite infestation, particularly in ceramic aquariums.

“…As diseases may cause severe morbidity and mortality, which can lead to economic losses in ornamental fish industry, prophylactic treatments should be used when the disease status and the infection source are known (FLORINDO et al, 2017). However, in general, a diagnostic workup of a subsample of the fish is the better method for identifying the problem.…”

“…Parasitic diseases are harmful and pose limiting factors in the rearing of ornamental fish. Nevertheless, several parasitological surveys (ALVES et al, 2000;PIAZZA et al, 2006;TAVARES-DIAS et al, 2009;KOYUNCU, 2009;GARCIA et al, 2009;MEHRDANA et al, 2014;MOYSES et al, 2015;FLORINDO et al, 2017) have been performed on freshwater ornamental fish and these studies verify a very diverse set of parasitic species. However, none of these surveys include aquarium fish cultured in the State of Amapá, (Brazil).…”

This study investigated the parasites fauna of four freshwater ornamental fish species in aquarium shops of Macapá, Amapá State, in addition to survey the commercialized fish species and sanitary conditions of aquarium shops. Different native and non-native ornamental fish species were found in aquarium shops, mainly Poecilidae. We examined 30 specimens of Xiphophorus maculatus, 30 Danio rerio, 30 Paracheirodon axelrodi, and 30 Corydoras ephippifer for parasites. Of the 120 fish examined, 22.5% were parasitized by one or more species and a total of 438 parasites were collected and identified. Parasites such as: Ichthyophthirius multifiliis, Monogenea, undermined Digenea metacercariae, Acanthostomum sp. metacercariae, Camallanus spp., Bothriocephalus acheilognathi and Echinorhynchus sp. infected the hosts examined. Endoparasites in the larval stage showed the greatest diversity and Camallanus spp. was found in all hosts species examined. Paracheirodon axelrodi (43.3%) was the most parasitized host, while C. ephippifer (6.7%) was the least parasitized. Despite the low ectoparasites level, six species of endoparasites was observed, demonstrating that prophylactic and quarantine procedures were not fully adequate. Therefore, failures in prophylactic procedures on any link in the production industry of ornamental fish may cause parasite transmission to ornamental fish captured in different environments and localities.
