Studies of blood biochemical variables make it possible to establish normal health conditions, detect physiological disorders, and provide information for the diagnosis and prognosis of diseases caused by nutritional, environmental, and health factors. Blood parameters are directly related to pathologies, as well as implying the relationship of cells and metabolites with reproduction, growth, and other physiological factors.
The main objective was to establish the hematological and blood biochemistry values of a wild population of grey mullet Mugil cephalus in northern Sinaloa.
The organisms were collected at different points in the coastal area of the municipality of Ahome, Sinaloa, known as “La Robalera and Bahía del Perro”. A total of 64 organisms were captured during two seasons of the year (spring and summer). The organisms were subsequently transported to the laboratory for dissection and further biochemical analysis (Figure. 1) glucose, cholesterol, triglycerides, and protein were analyzed in the blood of M. cephalus.
Significant differences (P<0.05), were found for triglycerides and total proteins about the seasons sampled. Several studies indicate the presence of seasonality in several hematological and blood biochemistry parameters in fish.
The average value found for erythrocyte lengths was 135.3 µm, there was a significant difference between erythrocytes lengths within stations (Pvalue < α=0.05), it was related to the environmental variations of the capture sites, abundance and availability for food.
