Hematological characteristics associated with parasitism in Pikeperch Sander lucioperca (Percidae) from Anzali Wetland

Abstract

A total of 120 Sander lucioperca (Percidae) were captured and investigated for parasites and also haematological parameters were analysed and compared between infected and uninfected fish. The haematological analysis showed reductions in haematocrit, haemoglobin, red blood cell, whereas with blood cell (WBC) and lymphocyte significantly increased (P \ 0.05) in infected fish, whereas with blood cell (WBC) and lymphocyte significantly increased (P \ 0.05) in infected fish. Parasitological inspections revealed the following infestations: Eustrongylides excisus (Nematoda), Dactylogyrus sp. (Platyhelminthes) and Achtheres percarum, Diplostomum spathaceum (Platyhelminthes) and Trichodina sp. (Ciliophora). The prevalence and intensity of the infection with parasites were varied at age groups of host. Significant differences were found for the white blood cell and lymphocyte in relation to parasitism. Parasitism had no influence on studied blood parameters of S. lucioperca in natural conditions.

Histopathological changes induced by the digenean intestinal parasite Masenia nkomatiensis Dumbo, Dos Santos, & Avenant‐Oldewage, 2019 of the catfish Clarias gariepinus (Burchell) from Incomati Basin, Mozambique

“…No significant difference in lymphocyte number was recorded between uninfected and infected fish, and it seems likely that the maseniid parasite did not stimulate lymphocytosis as reported by Movahed, Khara, Ahmadnezhad, and Sayadboorani (). However, Tavares‐Dias, Moraes, and Martins (), Hayatbakhsh et al () and Fallah, Khara, Rohi, and Sayadborani () reported an increased level of lymphocytes in fish with concurrent infections with helminths and protozoans.…”

“…No significant difference in lymphocyte number was recorded between uninfected and infected fish, and it seems likely that the maseniid parasite did not stimulate lymphocytosis as reported by Movahed, Khara, Ahmadnezhad, and Sayadboorani (2016). with Rhipidocotyle fennica (Jeney, Valtonen, Jeney, & Jokinen, 2002), while an increased leucocrit value was reported in fishes infected by trematodes (Khurshid & Ahmad, 2012;Restiannasab et al, 2016;Shah, Parveen, Mir, Sarwar, & Yousuf, 2009).…”

Influence of brief immersion in an aqueous solution of sodium chloride and/or copper sulphate on pikeperch (Sander lucioperca (L.)) blood parameters

“…These indicators are applied as tools to study the state of fish health (Blaxhall, 1972;Rożyński et al, 2019). Qualitative and quantitative changes in hematological and biochemical parameters are important criteria that serve to evaluate the health of an animal and to make diagnoses (Movahed et al, 2016).…”

Toxicological and therapeutic effects of neem ( Azadirachta indica ) leaf powder in hole‐in‐the‐head (HITH) disease of fish Anabas testudineus

“…Red blood cells (RBC) count was found to be decreased in the diseased control group and gradually increased in treated groups. The reason is that parasitic infection causes nutritional deficiency which reduces the haematopoiesis and RBC synthesis (Movahed et al., 2016). WBC count also increased in treated groups suggests immunostimulation after treatment, which may help to maintain the body homeostasis recovery from infection.…”
