“…The rate of first dose injection of PG can be given up to 4 mg/kg for carp species and the ovulation period in different species from 1.5 to 6 hours (Minar et al, 2012). In some cases the fishes induced in pituitary extract might take 11.55 to 16.35 hours for vacating the ovaries (Rumondang et al, 2015), where fishes receives less stress than the synthetic induced hormones (Berezina and Fomina, 2021;Brzuska, 2001;El-Hawarry et al, 2016;Okomoda et al, 2017). The regions of Jashore and Mymensingh in Bangladesh are home to the majority of the country's most important carp hatcheries (Al-Asif et al, 2014;Ali et al, 2018;Ali et al, 2016a;Faruk et al, 2018;Hossain et al, 2016;Rahman et al, 2016;Shabuj et al, 2016;Sharif and Al-Asif, 2015;Yeasmin et al, 2018Yeasmin et al, , 2016Zaman et al, 2017).…”

Fish hatcheries are generally regarded as the first step in the process of aquaculture development in any given nation. Fish breeding plays an important part in the process of supplying fry and fingerling to the farmers. The current study was conducted to identify the effectiveness of using dry and wet carp pituitary gland (CPG) in the induced breeding of mirror carp (Cyprinus carpio var. specularis), at Banchte Sheka fish hatchery Arabpur, Jashore from November to December 2021. The 1st dose of hormone, both for male and female brood fishes were injected with dry & wet PG at 0.8 mg PG/kg body weight. After 6 hours of the 1st dose, only female brood fishes were injected with the 2nd dose of hormone at 3 mg PG/kg body weight. After 6-7 hours of injection of 2nd dose, brood fishes became ready to spawn. The fertilized eggs were hatched after 42-48 hours. The ovulation rates were 100%. The fertilization rates were 88.3 % and 91.2% for wet and dry PG, respectively. The hatching rates were 84.2% and 87.5%, respectively. The survival rates were 79.5% and 83.3%, respectively. Therefore, dry CPG is highly recommended to hatchery owners considering the rate of fertilization, survival rate and availability. The information that has been offered here will be helpful to the owners of hatcheries when it comes to choosing the sort of pituitary gland to use in the breeding operation. Asian J. Med. Biol. Res. 2022, 8 (2), 115-122

“…In rare situations, fish produced in pituitary extract may take 11.55 to 16.35 hours to vacate the ovaries (Rumondang et al, 2015), with less stress than synthetically created hormones (Berezina and Fomina, 2021;Brzuska, 2001;El-Hawarry et al, 2016;Okomoda et al, 2017). In Bangladesh, the bulk of the most significant carp hatcheries are located in the areas of Jashore and Mymensingh (Al-Asif et al, 2014;Ali et al, 2018;Ali et al, 2016a;Faruk et al, 2018;Hossain et al, 2016;Rahman et al, 2016;Shabuj et al, 2016;Sharif and Al-Asif, 2015;Yeasmin et al, 2018Yeasmin et al, , 2016Zaman et al, 2017).…”

Stimulating hormone for artificial fish breeding in hatchery industry is very crucial for hatching operation, healthy fry and fingerling production, while overall fish production of a country. The present study was conducted to assess the effectiveness of using local and overseas Carp Pituitary Gland (CPG) in the induced breeding of Cirrhinus mrigala at Jashore district from April to May 2022. The first dose of hormone, both for male and female brood fishes were injected with local and overseas CPG at 0.5mg/kg body weight. After six hours of the first dose, only female brood fishes were injected with the second dose of PG at 5 mg/kg body weight. After 6 hours of second dose CPG injection of local and overseas PGs, brood fishes started spawning. The ovulation rates for both local and overseas PGs were estimated 100%. The fertilization rates were 93.5 % and 92.6 % for local and overseas PGs; while the hatching rates were 91.2% and 89.5%, respectively. However, local CPG is highly recommended to hatchery owners considering the rate of fertilization, hatching rate and availability. Asian J. Med. Biol. Res. 2022, 8 (3), 146-153

“…La hipofización aún hoy, continúa siendo una técnica aplicada ampliamente en Latinoamérica (Paschoalini et al, 2021) y África (Okomoda et al, 2017;Eyo et al, 2020), donde los costos de adquisición de inductores sintéticos importados suelen ser altos, obligando a los piscicultores a aprovechar extractos hipofisarios de peces nativos y otros vertebrados para estos fines (Streit Jr. et al, 2005;Martins et al, 2008;González et al, 2010). Dentro del grupo de extractos hipofisarios más usados resalta el extracto de pituitaria de carpa o EPC (Zaki et al, 2020, Caldas et al, 2021Romanova et al, 2021).…”

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.
