“…However, ATU and the number of egg releases were higher for females treated with buserelin acetate than CPE. 138 Positive results from use of buserelin acetate to induce spawning of tambaqui also were reported by Almeida et al 140 who monitored embryonic and larval development. Despite the various inducing agents available and experimentally demonstrated to induce spawning of tambaqui, CPE is still most commonly used because it is easily obtained and stored, easily handled (including calculation of dose) and proven effective.…”

“…Induced spawning and artificial propagation of tambaqui also can be accomplished by use of buserelin acetate, which yields spawning percentage, egg mass, ovulation and fertilization similar to those of CPE. However, ATU and the number of egg releases were higher for females treated with buserelin acetate than CPE 138 . Positive results from use of buserelin acetate to induce spawning of tambaqui also were reported by Almeida et al 140 who monitored embryonic and larval development.…”

Within the rich diversity of South American freshwater fish, Colossoma macropomum (Characiformes: Serrasalmidae), known as tambaqui, cachama or blackfin pacu, can reach 30 kg, is a traditional product in regional fish markets and has drawn the attention of fish farmers since the 1930s. Considerable progress achieved in different fields of aquaculture science has contributed to the growth of tambaqui production.

“…Since the discovery of the sequence of the mammalian peptide GnRH 124 and other similar peptides in fishes 125 such as ‐s‐GnRH (salmon), various synthetic analogues with higher biological activity have been designed by replacing the amino acids in positions 5–6 and 9–10, 90 and these analogues; have been used to induce spawning of C . macropomum , 126 P . mesopotamicus 24 and Rhamda quelen 127 .…”

Aquaculture offers solutions to meet the growing global demand for fish, and reports from the UN‐FAO indicate that aquaculture production in Latin America (LA) has grown at rates above the world average in recent years. One of the major constraints in the diversification of LA aquaculture is the control of reproduction in several popular native fish species for which difficulties in captive propagation have not yet been sufficiently overcome. This article reviews the use of hormone treatments to promote reproduction in females of these native fish species. LA has played a key role in the history of development of hormone administration, including the first hormonally induced spawning. That contribution is included in a historical overview of the discovery of the major hormones used in fish culture. The review provides a summary of difficulties to propagate females of various native fishes and the effects of administering hormones to enhance reproduction. Induced spawning of certain freshwater species was mainly achieved with pituitary extracts or human chorionic gonadotropin (hCG), although gonadotropin‐releasing hormone analogues (GnRHa) treatments are being researched, and successful studies suggest that low doses may be more effective. Research on new and emerging aquaculture species has applied both gonadotropins (Gths) and GnRHa‐based treatments, and GnRHa treatments have shown potential for marine species. However, native marine species new to aquaculture have also been conditioned to spawn spontaneously without hormones. Finally, we proposed future lines of research to examine reproductive strategies and GnRHa‐based hormone treatments to improve reproductive control for economically important fish species of LA.

“…Estudios de reproducción inducida de gamitana tratada con EPC también registraron altas tasas de desove en este pez reofílico, variando desde 87,5 ± 7,0% (Souza et al, 2018) hasta 100% (Acuña & Hernández, 2009Leite et al, 2013;Pires et al, 2017;Sevignani et al, 2020), confirmando la efectividad de este extracto hipofisiario. Por otro lado, Konzen-Freitas et al (2020) reportaron tasas de desove cercanos al 40% en hembras adultas de C. macropomum inducidas con EPC y un análogo de la GnRH, el acetato de buserelina. Mientras nuestros resultados con EPP fueron superiores a los obtenidos por Konzen-Freitas et al (2020) con estos dos inductores.…”

La hipofización fue la primera técnica de reproducción inducida conocida en piscicultura y sigue siendo una técnica aplicada hasta la actualidad. El objetivo del estudio fue evaluar la respuesta reproductiva de machos y hembras adultas de gamitana Colossoma macropomum, inducidas con inyecciones de extracto de pituitaria de paiche (EPP) y extracto de pituitaria de carpa (EPC). Utilizamos diez hembras y diez machos con un peso corporal promedio de 6,81 ± 1,86 kg y 6,59 ± 2,34 kg, respectivamente. Cuatro hembras fueron tratadas con el extracto de hipófisis de carpa (EPC) a 6,0 mg/kg de peso corporal, mientras que otras seis recibieron el extracto de pituitaria de paiche (EPP) a razón de 3,5 mg/kg de peso corporal. En ambos casos la dosis fue administrada en dos inyecciones (10% al inicio y 90% doce horas después). Cuatro machos fueron inducidos con EPC y seis con EPP a razón de 1 mg/kg de peso corporal administrados en dos dosis de 50%, al mismo tiempo que las hembras. Las hembras inducidas con el EPP desovaron en su totalidad, mientras que con el EPC solo el 75% de ellas. La tasa de desove, así como las medias de peso total de ovocitos desovados, número de ovocitos por gramo, fecundidad absoluta, tasa de eclosión y el número total de larvas producidas de los dos tratamientos hormonales utilizados en el presente estudio no presentaron diferencias significativas (P>0.05). El presente trabajo demostró que es posible realizar la reproducción inducida de Colossoma macropomum utilizando el extracto de pituitaria de paiche.
