Habitat, Associations and Competition of Eight Barbus (= Puntius) Species (Pisces, Cyrinidae) Indigenous To Sri Lanka

Habitat, Associations and Competition of Eight Barbus (= Puntius) Species (Pisces, Cyrinidae)... HABITAT, ASSOCIATIONS AND COMPETITION OF EIGHT BARBUS (= PUNTIUS) SPECIES (PISCES, CYRINIDAE) INDIGENOUS TO SRI LANKA by JALB SCHUT1, SENA S. DE SILVA2 and KOENRAAD KORTMULDER1 (1 Zoölogisch Laboratorium, University of Leiden, Postbus 9516, 2300 RA, Leiden, The Netherlands*) (2 Department of Zoology, University of Ruhuna, Matara, Sri Lanka) SUMMARY A detailed description of the typical habitats of 8 Barbus species of Sri Lanka is given. The distribution of their typical habitats over the various waters leads to the grouping of species in associations. Quantitative analysis of catching data corroborates these groupings.
