Hematology of catan (Astractosteus spatula), collected in northeastern México
Abstract
Gar populations (Atractosteus spatula), have been decreased dramatically over the past two decades in northeastern Mexico, mainly due to the capture and loss of habitats by anthropogenic activity and pollution. Therefore it is important to know their biology and hematology in particular because it is a fabric which quickly reflects both intrinsic and extrinsic changes caused by the environment. The hematological parameters studied were hemoglobin (Hb = 12.45 g / dl), Microhematocrit (Ht, = 44.33%) Leucocrito (Lc, = 2.76%), Total Plasma Protein (PTP, = 5.48 g / dl), count by Dilution of Red Blood Cells (RDR = 1.004 million), Count White Blood Cell Dilution (RDB, = 64 471). Quantified cells for the differential count were: Platelets (= 46.5), neutrophils (= 4.5), eosinophils (= 3.14), basophils (= 3), Lymphocytes (= 26.6), Monocytes (= 5.42), plasma cells (= 6.56 ), Promyelocytes (= 1.67), Myelocytes (= 0.31 ± 0.66), Unidentified cells (= 1.25 ± 1.33). Haematological values reported are consistent with those reported for other fish, but not the diversity of leukocytes.
