Size at onset of sexual maturity in Macrobrachium amazonicum (Heller, 1862) phenotypes: an integrative approach.

Anais da Academia Brasileira de Ciencias - 1 Jan 2020

Paschoal Lucas R P, Zara Fernando J

Abstract excerpt

The size at the onset of sexual maturity (SOM) was determined in four hololimnetic populations of Macrobrachium amazonicum using morphometric, physiological and functional criteria. Male prawns from two populations analyzed had hypertrophied chelipeds and large body proportions, showing the presence of four morphotypes, i.e. large-size phenotype (LS). However, the other two populations showed smaller males...
