INDUÇÃO A REPRODUÇÃO DE JUNDIÁ UTILIZANDO DIFERENTES HORMÔNIOS

The objective of this work was to evaluate different hormones (equine chorionic gonadotrophin) and crude carp extract in the induction of jundiá (Rhamdia quelen) reproduction. The experiment was conducted at UNIPAMPA-Campus Dom Pedrito, in April 2019. 6 females and 12 males Jundiá (Rhamdia quelen) were used. The experiment was divided in 3 treatments: EBHC (3mg / kg), EBHC + ECG (3 mg + 500UI / kg) and ECG (500 IU / kg), with a 12 hour interval. The observed parameters were: UTA; oocytes released by extrusion and fertilization rate. It was observed in this experiment that only on EBHC + ECG treatment 100% spawning occurred. And the accumulated thermal unit (U.T.A.), using different hormones, presented a significant difference (P <0.05) for the total spawning time, where EBHC + ECG treatment obtained the lowest U.T.A. Considering the oocytes released by extrusion did not present statistical difference. For fertilization rate, treatment with EBHC showed a significant difference (P <0.05), with 98.6 ± 0.58%, differing from the other treatments. According to the data presented by the present study, the efficacy of the carp pituitary associated with equine chorionic Gonadatrophin as hormone inducer in spawning and spermiation of jundia (Rhamdia quelen).
