Abstract
In the Peruvian Amazon, there is no information about hematological parameters of parasitized fish maintained in fish farms. In this study, the effects of parasitism by Anacanthorus spathulatus on hemoglobin (Hb), hematocrit (Ht), red blood cells (RBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), glucose levels, and leucocytes were analyzed in Colossomamacropomum. The low level of parasitism found in the fish was not responsible for alterations in Hb, Ht, RBC, MCV, MCH, MCHC, and leucocytes (0.05 > p). However, significant increases were observed to the levels of glucose (p < 0.05). This is the first report regarding hematology of cultivated freshwater fish which are infected with monogeneans in the Peruvian Amazon.
