Parasitic infections in ornamental cichlid fish in the Peruvian Amazon

Abstract

The aim of this study was to evaluate the prevalence and seasonal distribution of the main parasite species in Amazonian ornamental cichlids that affect their trade. The study was conducted from August 2007 to September 2009. We sampled 3042 specimens from 9 different species, of which 9.47% had at least one type of external parasite. 81.25% of the cases occurred in the dry season. Crenicichla anthurus (28.57%) was the most parasitized, followed by

Seasonality of parasitic helminths of Leporinus macrocephalus and their parasitism rates in farming systems in the Amazon

“…Parasites are abundant in tropical regions and their presence is one of the main causes of death among fish (AGUINAGA et al, 2015). Thus, understanding the agents that cause parasitic diseases and the complex relationship between environmental factors and hosts and their parasites is important.…”

Community ecology of parasites in four species of Corydoras (Callichthyidae), ornamental fish endemic to the eastern Amazon (Brazil)

“…The capture and transport of Amazonian wild ornamental fish can cause stress due to inadequate management, which can lead to parasitic infections and high mortality rates of host populations. These fish presents a peculiar fauna of parasites and when captured and kept in culture with high population density, they may present high rates of parasitic infections (Ferraz 1999, Tavares-Dias et al 2010, Aguinaga et al 2015, Hoshino et al 2018. Parasites, an inseparable component of the environment, are often the major cause of mortality and elimination of fish by the ornamental fishery (Ferraz 1999, Tavares-Dias et al 2010, Aguinaga et al 2015, which represents high biological losses.…”

Thus, considering the importance of parasites, studies on these organisms can serve as basis for a series of investigations, such as parasite-induced pathology, use of parasites as bioindicators of water quality, ecological and economic impacts caused by invasive species and their parasites, etc.…”
