Induced spermiation ofPimelodus britskii(Teleostei: Pimelodidae) during the reproductive period

Aquaculture Research, 2015
For the first time was characterized the semen of Pimelodus britskii, hormonally induced and non-induced induced, during the reproductive period. The experiment 1 was conducted with 12 fish per month, divided into: (i) induced with Carp Pituitary Extract (CPE), and (ii) without hormonal induction (testes macerated). The experiment 2 was conducted, with

Effects of river damming in Neotropical piscivorous and omnivorous fish: feeding, body condition and abundances

Neotropical Ichthyology, 2016
The increase in abundance of small-sized fishes is common after a reservoir is formed. There is an increase in the consumption of fish, from typically piscivorous fish to opportunistic species that take advantage of abundant resources. This study aims to
