Length‐weight relationship of three cichlid species in a stream in southwestern Amazon, Brazil

Summary The paper investigates the length‐weight relationship of three cichlids species for the southwestern Amazon, Acre state. The individuals were collected at five sites during one year among august/2016 and june/2017 in Quinoá stream (10°06′03.33″S/67°40′11.50″W). The individuals were collected using: seine net, 6 m length, 2.25 high, and mesh size 5 mm, two dip nets, 5 mm mesh, 30 cm width, and 50 cm in length and two sieve with 5 mm mesh, 50 cm width, and 80 cm in length. The results show that one species presented positive allometric growth ( Aequidens tetramerus ) and the others negative allometric growth ( Apistogramma acrensis  and  Crenicichla semicincta ).
