The matrinxã Brycon amazonicus (Spix & Agassiz, ) is a rheophilic species native to the Amazon basin, which has great potential as a fish. Estudo comparativo sobre parâmetros hematológicos de matrinxã Brycon amazonicus Spix e Agassiz, (Characidae: Bryconinae) criados em cativeiro, com. In the present work we describe the larval development of Brycon amazonicus, with emphasis on structures linked to swimming, respiration and.

Neutrophils are effector key cells in non-specific immunity, as they migrate into the infection site, to recognize, ingest and destroy many pathogens Tavares-Dias and Moraes, ; Tavares-Dias, ; Tavares-Dias and Moraes, ; Pavlidis et al. From 46 to 48 h AF, it was possible to distinguish blood circulation through reddish flow, and the yolk was almost totally absorbed.

Blood parameters varied between Bryconinae species investigated, mainly the red blood cell counts, hemoglobin, hematocrit and mean corpuscular volume MCV. Development of feeding structures in larval fish with different life histories: Thus, no fish with signs of disease or parasites were used.

The main events recorded at each amazonicua of embryonic and larval development were presented in chronological order Table 1divided into two stages, the embryonic and larval stages, and the main characteristics were described based on external features. Brycon support important fisheries and based on a review by IBAMAthey are the fifth most caught fish by weight in the Brazilian Amazon.

Successive cell divisions resulting in 02, 04, 08, 16, 32 and 64 blastomeres. Therefore, this important taxonomic review finished with a hindrance that hindered studies of comparison of blood features among Bryconinae species from literature.

Brycon orbignyanus Acta Scientiarum: A new species of Brycon Characiformes: Neutrophils and heterophils were brydon granulocytes found in B. Intensification of movement for hatching; asynchronous hatching, non-pigmented larvae, first movements of swimming. However, no comparison study for hematological parameters among Bryconinae species has been reported, until the present moment.


In summary, for B. We couldn’t load this image at the moment. The ingestion of Aeromonas salmonicida by fish blood phagocytes in vitro under influence of herbicides. Heterophils and neutrophils have similar functions, but different morphological features Tavares-Dias and Moraes, Saved one filter Removed from saved filters.

Emergence of otic vesicle and visualization of two pairs of otoliths; early detachment of the tail and calf. Total retinal pigmentation and expansion of chromatophores on the cranial region. In this work, chromatophores distributed on the retina could only be brycln in B.

At this time, the body pigmentation extended over the pectoral region, with greater intensity in the brycoj and lateral regions. The gastrula stage, beginning 02 h 40 min AF, was characterized by progressive regression cells and the formation of the embryonic axis, leading to differentiation of the head and tail 05 h 30 min AF.

The selected fish were induced according to the protocol described by Bernardino et al.
