This study involved 120 pike, Esox lucius, captured from Anzali wetland. Parasite fauna were identified in captured fish. Also, changes of haematological parameters were compared both infected and uninfected fish. Parasitological inspections revealed the following infestations: Skin: Lernea cyprinacea, Argulus foliaceus (Crustacean) and Tricodina sp. (Ciliatea). Gill: Dactylogyrus sp. (Digenea) and Tetraonchus monenteron (Monogenea). Eye: Diplostomum spathaceum (Digenea). Gut: Eustrongylides exises, Rhipdocotyle illense, Raphidascaris acus (Nematode), Corynosoma Strumosum (Acanthocephala). Most prevalence and intensity were related to Eustrongylides exises and Rhipdocotyle illense. Following haematological parameters were evaluated: haematocrit, haemoglobin concentration, erythrocyte and leukocyte counts, mean cell volume (MCV), mean cell haemoglobin, mean cell haemoglobin concentration lymphocytes, monocytes and eosinophils. Significant difference was found for MCV between infected and uninfected fish.
本研究涉及从安扎利湿地捕获的120条白斑狗鱼（Esox lucius）。对捕获的鱼进行了寄生虫区系鉴定。此外，还比较了感染和未感染鱼的血液学参数变化。寄生虫学检查发现了以下感染情况：皮肤：鲤锚头鳋（Lernea cyprinacea）、叶状锚头鳋（Argulus foliaceus，甲壳纲）和车轮虫属（Tricodina sp.，纤毛虫纲）。鳃：指环虫属（Dactylogyrus sp.，复殖吸虫纲）和单殖吸虫（Tetraonchus monenteron）。眼睛：匙形双腔吸虫（Diplostomum spathaceum，复殖吸虫纲）。肠道：艾氏真圆线虫（Eustrongylides exises）、伊利伦斯裂口吸虫（Rhipdocotyle illense）、尖锐绕线虫（Raphidascaris acus，线虫纲）、粗壮吻钩绦虫（Corynosoma Strumosum，棘头虫纲）。大多数感染率和感染强度与艾氏真圆线虫和伊利伦斯裂口吸虫有关。评估了以下血液学参数：血细胞比容、血红蛋白浓度、红细胞和白细胞计数、平均红细胞体积（MCV）、平均红细胞血红蛋白、平均红细胞血红蛋白浓度、淋巴细胞、单核细胞和嗜酸性粒细胞。感染和未感染鱼之间的MCV存在显著差异。
