Size at onset of sexual maturity in Macrobrachium amazonicum (Heller, 1862) phe...
PASCHOAL,LUCAS R.P.; ZARA,FERNANDO J.Abstract 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 m...

In November 2012, three quarters of 100 m2 were sampled in this reservoir, where 812 dead shells of ...
