A possible function of the caudal spot in characid fishes

Canadian Journal of Zoology, 1977
The suggestion that caudal pigment spots in fishes can act as deflection marks is tested experimentally. Fish with artificial caudal spots escape predators more often than the same species without spots, but the difference was not significant (0.1 < p < 0.2).

Phosphoglucose isomerase isozymes in the characid fish Cheirodon axelrodi: Evidence for a spontaneous gene duplication

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
Abstract 1. 1. 132 specimens of the Characid fish Cheirodon axelrodi were examined for phosphoglucose isomerase (PGI) using starch gel electrophoresis 2. 2. Cheirodon axelrodi is endowed with two different PGI gene loci, both occurring in multiple alleles. 3. 3.

Genetic Diversity of the Small Characid Fish Astyanax sp., and its Significance for Conservation

Hydrobiologia, 2004
Genetic variations in Astyanax sp. fish from Vila Velha State Park and Tibagi river (Parana, Brazil) were analyzed by RAPD. Intrapopulational genetic similarity was analyzed at three collection sites. The higher RAPD polymorphism observed at site 3 (Tibagi river) suggests either an overlapping of structured populations or the presence of coexisting ...
