Light and electron microscopy oogenesis in matrinxã, Brycon cephalus.

Journal of submicroscopic cytology and pathology, 2003
Oocyte development has been divided into 5 distinct stages in the reared matrinxã, Brycon cephalus, based on morphological criteria by light and transmission electron microscopy: I) chromatin-nucleolus; II) perinucleolar; III) cortical alveoli; IV) vitellogenesis; V) final maturation.

Effect of stocking density on water quality, survival, and growth of larvae of the matrinxã, Brycon cephalus (Characidae), in ponds

Aquaculture, 2000
Experiments were carried out in nine 64 m2 ponds at CEPTA/IBAMA over a period of 21 days in order to evaluate the effect of stocking density (StD) on survival and growth of larvae of matrinxa, Brycon cephalus. The larvae were randomly divided into treatments of 30, 60 and 120 larvae m2 (three replicates per treatment) and fed three times a day. Samples

Structural and Ultrastructural Characteristics of Interrenal Gland and Chromaffin Cell of Matrinxã, Brycon cephalus Gunther 1869 (Teleostei‐Characidae)

Anatomia, Histologia, Embryologia, 2001
This work presents the structure and ultrastructure of the interrenal gland and chromaffin cells, as well as the morphology of the head kidney of Brycon cephalus. The head kidney is composed of fused bilateral lobes located anterior to the swim bladder and ventrolateral to the spinal column.

Crystallization, preliminary X-ray analysis and molecular-replacement solution of haemoglobin-II from the fish matrinxã (Brycon cephalus)

Acta Crystallographica Section D Biological Crystallography, 2003
Haemoglobins constitute a set of proteins with interesting structural and functional properties, especially when the two large animal groups reptiles and fishes are focused on. Here, the crystallization and preliminary X-ray analysis of haemoglobin-II from the South American fish matrinxã (Brycon cephalus) is reported.
