Ocorrência de Ectoparasitos em peixes redondos de piscicultura de Laranjal do Jari (AP)

Abstract

The municipality of Laranjal do Jari is a region known for its fish farming activity, mainly the farming of round fish, such as tambaquis and tambacus. However, this activity can be affected by the occurrence of ectoparasites. Ectoparasites are organisms that live externally in the host's body, causing damage and health problems. In round fish in the Jari orange grove, some common ectoparasites are the protozoa Ichthyophthirius multifiliis (ichthyus), monogenoids (worms) and leeches. Ich is an extremely harmful disease for fish, one of the most common and can cause serious illnesses in fish, such as loss of appetite, skin lesions, delayed growth and mortality. Monogenoids are also quite prevalent and can infect fish gills, damaging their breathing and feeding. Leeches feed on the blood of fish, causing anemia and weakness. The occurrence of ectoparasites in round fish from fish farms in Jari's Orangery can be influenced by factors such as water quality, fish density in tanks and management practices. It is important to regularly monitor the health of fish, using appropriate diagnostic methods to identify and treat the presence of ectoparasites. To control and prevent these ectoparasites, measures can be adopted such as treatment with antiparasitic medications, cleaning and disinfecting tanks, maintaining good water quality conditions and controlling the density of fish in tanks. Furthermore, it is essential that round fish breeders pay attention to good management practices and the general health of the animals to prevent the occurrence of these parasites.
