Supernumerary chromosome inheritance in the curimbatá (Prochilodus lineatus) of the Mogi-Guaçu River.
Prochilodus lineatus is widely used in pisciculture projects, mainly in the south of Brazil. It shows a basic karyotype composed of 2n = 54 chromosomes, in addition to as many as seven supernumerary chromosomes, also known as B-chromosomes. These additional small chromosomes are frequently heterochromatic, vary in number and morphology, and generally have no homology with the A complement. Inte...

متن کاملMigration of the curimbatá Prochilodus lineatus (Valenciennes, 1836) (Pisces, Prochilodontidae) at the waterfall "Cachoeira de Emas" of the Mogi-Guaçu river--São Paulo, Brazil.
In this paper, we counted the ascending curimbatás at the fish ladder at the Cachoeira de Emas from October, 1992 to September, 1993 in one whole day (24 h period) per month at different observation points in the dam for 5 min every hour. Most of the fish (80%) were counted not in the fish ladder itself, but in two adjacent spillways at its left, perhaps due to the comparatively increased flow ...
متن کاملGill parasites of Prochilodus lineatus ( Valenciennes , 1836 ) ( Pisces ;
We studied gill parasites of Prochilodus lineatus in the San Javier River, which is connected to the Middle Paraná System (Santa Fe, Argentina). In 25 specimens, the parasite prevalence in branchial organs was 92% and the average intensity was 8.3 parasites/infested fish. The parasite community showed no dominance of any taxon, but the family Dactylogyridae represented 60% of the community. We ...
