Hematological parameters of three species of the peacock bass (Cichla spp.) from Balbina lake, Presidente Figueiredo, Amazonas, Brazil

Abstract

The objective of this study was to characterize and compare the hematological variables (erythrogram, thrombogram, leukogram and plasma metabolites) of three cichlid species: Cichla monoculus, Cichla temensis and Cichla vazzoleri. A total of 45 specimens were captured in Balbina lake, Presidente Figueiredo, Amazonas, Brazil, with the aid of a rod and reel or hand line, with natural or artificial bait: 15 C. monoculus, 15 C. temensis and 15 C. vazzoleri. Their blood was removed by means of caudal puncture of the dorsal aorta, and hematological data were determined in accordance with methodology previously described in the literature. The erythrogram showed similarities between the species, while the thrombogram showed differences between C. vazzoleri and the other species studied (C. monoculus and C. temensis). The total leukocyte counts for C. temensis and C. vazzoleri were higher than those of C. monoculus. The predominant leukocyte in C. temensis and C. vazzoleri was lymphocytes, whereas it was monocytes in C. monoculus. The plasma metabolites showed differences between the three cichlid species, regarding their glucose, cholesterol, urea and potassium levels. It is concluded that these three species present hematological differentiation, thus indicating that they have differentiated blood-cell immune responses and plasma metabolite physiology.

“…Para a pescada os valores de hematócrito e VCM foram inferiores a outras espécies da ordem perciforme, tais com as espécies de tucunaré Cichla monoculis, Cichla temensis e Cichla vazzoleri (Castro et al, 2020).…”

“…os valores de glicose e triglicerídeos foram superiores ao retratado para C. monoculos, C. temensis e C. vazzoleri, entretanto as demais análises mensuradas apresentaram valores similares(Castro et al, 2020), essas diferenças podem ser reflexões das diferentes localidades em que os animais foram capturados, vale ressaltar que e mambas as situações os animais foram oriundos de ambiente natural.…”

Ecophysiological interactions in species of peacock bass Cichla spp. from the Amazon

“…Among the members of the Amazon peacock bass ichthyofauna Cichla spp. show great economic, ecological and social importance, because sport fishing that occurs in the Middle Negro River (Barcelos) and along the Uatumã River, including the Balbina Reservoir (CASTRO et al, 2020). The peacock bass are also appreciated for flavor, due to its organoleptic characteristics of your meat, considered being very tasty.…”
