“…Currently, the greatest difference between food fish aquaculture and ornamental fish aquaculture is the commercialization method, where the ornamental fish are sold per unit and not by weight (Igarashi et al, 2004;Faria et al, 2019). Therefore, increasing stocking density makes the production system economically viable (Novák et al, 2020;Perera et al, 2023). The high stocking densities in the present study did not affect the growth of fish, making it more profitable for ornamental fish farmers (Çağiltay et al, 2017;Abe et al, 2016).…”

“…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).…”

“…Brazil occupied the ninth position in the world ranking of ornamental fish exportation, generating approximately US$18 million. Among the various native fish species, the angelfish Pterophyllum scalare belongs to a unique group with the 30 most commercialized ornamental fishes worldwide (Eiras et al, 2022;Perera et al, 2023).…”

“…The popularity of P. scalare among fish farmers and hobby fishers relates to captivity adaptation, ease of reproduction, and acceptability as industrial food, making it economically viable (Gallani et al, 2016). For these reasons, the captive rearing of P. scalare in intensive production systems has been growing annually (Perera et al, 2023). However, some handling procedures from these systems, such as inadequate stocking densities, can reduce fish health and impair profits for fish farmers (Pinheiro-Junior 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.
