Morphometry of white muscle fibers and performance of Nile tilapia (Oreochromis niloticus) fingerlings treated with methyltestosterone or a homeopathic complex

Abstract

Fish treated with the homeopathic complex had improved survival and muscle fiber hypertrophy, but were smaller (probably related to increased survival and overcrowding) compared to fingerlings treated with synthetic hormone or control.

Homeopathy improves production and hatching probability of zebrafish eggs

“…The effect of homeopathy on productive performance and meat quality in fish has been evaluated, mainly for Nile tilapia. Remarkable results have been observed, such as increased muscle hypertrophy, survival, decrease in lipid content and omega 6:3 ratio (Júnior et al, 2012;Andretto et al, 2014). Scientific studies report that homeopathy causes minor liver damage, greater storage of glycogen and a lower hepatosomatic rate, besides not influencing the quality __________________ Corresponding editor: Jesús Ponce Palafox of meat and derived products and improving breeding rates, such as spawning frequency and larvae hatching (Valentim-Zabott et al, 2008;Siena et al, 2010;Braccini et al, 2013;Andretto et al, 2015;Lima et al, 2015;Pinheiro et al, 2015) demonstrating that the product Homeopatila 100 ®, when acting as a hepatoprotective, can influence important factors in the production, growth, reproduction, and quality of meat.…”

Morphometric comparison of the growth curve in Nile tilapia (Oreochromis niloticus) sexually reverted to masculinized and feminized

“…Aquaculture participates in the human diet with 59.4 million t worldwide, where Mexico contributes with 1.1% of the fishing and aquaculture production (Hasan & Halwart, 2009). Currently, there has been an increase in interest in the cultivation of masculinized Nile tilapia Oreochromis niloticus (El-Greisy & El-Gamal, 2012;Megbowon & Mojekwu, 2013), mainly due to its accelerated growth, good adaptation to different environmental conditions and its high level of nutrition-__________________ Corresponding editor: Mauricio Laterça nal quality (Chakraborty et al, 2011;Hasheesh et al, 2011;Junior et al, 2012). However, the traditional crop of tilapia, constituted mainly by heterosexual organisms, has some drawbacks such as early maturation, a high percentage of fertility and frequent spawning (Minton, 2009) That increases the presence of juveniles and the variation in the size and weight of the fish at the time of harvest (Ezaz et al, 2004).…”

“…Several strategies have been developed to avoid this, producing monosex crops mainly of males (Juárez-Juárez et al, 2017). In the cultivation of masculinized organisms, a high and homogeneous rate of body growth is maintained (Junior et al, 2012), avoiding variations in the size of the harvest and uncontrolled reproduction (Megbowon & Mojekwu, 2013).…”

Homeopathy outperforms antibiotics treatment in juvenile scallop Argopecten ventricosus : effects on growth, survival, and immune response

“…The Nile tilapia Oreochromis niloticus has been treated with homeopathic complexes, such as Ho-meopatilaÔ to increase reproductive performance and success of adults, 29 and increase muscle quality in juvenile stock. 30,31 Treatments applied to tilapia O. niloticus are able to increase morpho-functional response and the content and quality of fatty acids in muscle, 32,33 as well as to modulate content of cortisol in muscle. 34 In another important edible fish, the pacu Piaractus mesopot amicus, physiological response to stress was successfully modulated with homeopathy.…”
