KARYOLOGY OF MUGIL LIZA AND M. CUREMA FROM VENEZUELA

Mauro Nirchio T., Hernán Cequea

Abstract


Karyotypes of Mugil liza and M. curema from Venezuela were studied. M. liza karyotype is 2n=48 acrocentric chromosomes, but M. curema is 2n=24, containing one submetacentric and 11 metacentric pairs. The chromosomic complement described for M. liza constitutes the first report for the speciesand coincides with the modal karyotype (2n=48) in the Mugilidae family. Venezuelan M. curema karyotype differs in number and shape from M. curema from Louisiana (USA), which has been reported to have a complement 2n=28 (10 metacentric pairs, two subtelocentric pairs and two acrocentric pairs).
