Largemouth bass, Micropterus salmoides, growth and reproduction in Primera de Palos’ lake (Huelva, Spain)

Some aspects of the biology of Micropterus salmoides such as growth, population structure and reproduction, were studied in the Primera de Palos’ lake. A total of 200 specimens were captured (98 females, 86 males and 16 juveniles) and distributed into seven different age-classes (from 0+ to 6+). Spe...
