“…De acuerdo con el presente trabajo, se puede observar que la eliminación de la capa adherente de huevos del bagre asiático, P. hypophthalmus con ácido tánico e incubados a 28°C, mejoran sustancialmente la eclosión (84.7±1.3%). Porcentajes de eclosión similares, entre 80-85 %, fueron reportados en beluga, Huso huso, cuando emplearon también ácido tánico a una concentración de 0.5 g L -1 y un tiempo de exposición de 1.5 minutos en huevos de esta especie (20). También se reportaron porcentajes de eclosión superiores al 80% en la lucioperca, Sander lucioperca, al eliminar la capa adherente de los huevos con ácido tánico a una concentración de 0.75 g L -1 y un tiempo de exposición entre uno y dos minutos (10).…”

Objetivo. El propósito del presente trabajo fue evaluar el efecto del ácido tánico y de las proteasas para eliminación de la capa adherente en huevos fecundados de bagre asiático, P. hypophthalmus, para mejorar las condiciones de incubación. Materiales y métodos. Se utilizó ácido tánico a 0.5 g L-1 por 5 min, proteasa a 5 mL L-1 por 8 min para la eliminación de la capa adherente de huevos fecundados y un grupo control, sin la adición de estos químicos. Todos los tratamientos fueron incubados a 26, 28 y 30°C, para determinar el porcentaje de eclosión. Todos los tratamientos fueron realizados por triplicado. Resultados. Los huevos tratados con proteasa no eclosionaron en ninguna temperatura de incubación, mientras que los tratados con ácido tánico e incubados a 26 y 28°C tuvieron porcentajes de eclosión mayor al 60%, siendo los porcentajes de eclosión más altos (84.7±1.3%) los que se obtuvieron a 28°C. Los huevos del grupo control presentaron los porcentajes de eclosión significativamente más altos (14.2±0.6%) cuando fueron incubados a 28°C que a 26 o 30°C. Conclusiones. Los resultados mostraron una significativa interacción entre el tipo de desgomado y de la temperatura de incubación, indicando que el ácido tánico produce el mejor porcentaje de eclosión a los 28°C.

“…First, the tannin products used may have different properties depending on the origin and supplier since these compounds are known to have a variety of mo lecular weights and usual characterizat ion of tannin provided by suppliers refers only to the final ratio of glucose to gallic acid mo lecules (Makkar & Becker, 1993). The reports on hatchery used tannins usually have no characterizat ion of tannins except providing the name of supplier (Demska -Zakes et al, 2005;Hosseini & Khara, 2015;Zarski et al, 2015). Second, the reason may lie in different water quality parameters.…”

The methods for removal of adhesiveness in pikeperch eggs were compared in this study . Following the hormonal induction with carp pituitary, eggs of three females were used in each of two trials. Firstly, three common methods were tested: tannic acid, enzyme and milk. Tannic acid treatment led to poor hatching (2.5±0.5%), significantly lower than the other treatments (75.5±19.3% and 72.3±28.8%, enzyme and milk, respectively). In order to find the source of negative outcome, in the second trial the influence of water hardness on the tannic acid bath was tested through three treatments with varying concentrations of disodium ethylenediaminetetraacetic acid salt (NA 2 EDTA). Softening of the tannic acid bath did not lead to improved hatching rates (5.5±1.3%, 3.5±1.5% and 2.7±1.3% for 0, 400 and 800 ppm of EDTA, respectively). Evaluation of the effects of tannin and EDTA on water chemistry revealed that the use of tannin can alter the embryonic development and hatching process. While de-adhesion procedure with milk appeared to be impractical, the application of tannic acid bath leads to variable and lower hatching outcomes. Thus, usage of enzymes was found to be the most promising method which should be further described for straightforward implementation in practice.

“…For this purpose many different traditional materials were used such as urea solution, food salt and Tannin solution (Horvath,1985).Pomegranate appeals and white alum also been used (Nife,2011). Grazina et al (2018) referred that Tannic acid, milk and salt solutions were used to remove the sticky substances from Common carp egg, Tibor, et al, (2011) used milk and starch ,while (Linhart, et al, 2008 ;Sunil, 2012) used Alkaline enzyme DX PLM4715 and NA2EDTAenzyme of disodium ethylene diaminetetraacetic acid salt on Pike perch fish egg (Uros,et al,2017).While clay was used for Huso huso fish by ©Annals of Tropical Medicine & Public Health S447 (Hosseini and Khara ,2015) , and Pineapple extract juice for Mud fish egg, (Ekokotu and Nwachi, 2014) and also for Cat fish Clarias gariepinus eggs, and Common carp fish Cyprinus carpio (AL-humairi,2016).The dependence on artificial reproduction in fish farms is to support this expansion in fish farming for the purpose of producing genetically modified fortified varieties (Al-Jebory,2011 ;Al-Jebory,2012).As well as increasing fertilization and hatching rateto increase the number of larvae produced during one season of breeding and the interplay between them(AL-Gezali,2010).Common carp fish considered as one of the most important cultivated fish in fresh water and there is several ways are used to artificially reproduce them ( (Brzuska, 2006 ).One of the most important things in artificial reproduction of Common carp is the removal of adhesion of eggs (Grazina,et al,2018). Adhesion of eggs considered a serious problem in the process of artificial reproduction, which reduces the rate of fertilization and hatching.…”

One of the most important problems during artificial reproduction of Common carp is the adhesion of its egg. Disposal of adhesive material on eggs increasing its hatching rate activity. In this research three different concentrations of Strawberry Juice were used (10, 15 and 20% respectively) to treat the eggs of Common carp fish in order to remove the adhesive materials comparing with the control (salt, urea and Tannin solutions). The results showed that using Strawberry Juice after eggs fertilization with concentration of 20 and15 % have the possibility of removing the adhesive substances with short time of about 5 and 7 minutes respectively with significant effect ( p>0.05) as compared with the control treatment which it takes about75 minutes to remove this substance. While the concentration of10 %the adhesive materials were not removed. Additionally there was a surpassing effect (p>0.05) at the rat of eggs fertilization and hatching in the both concentrations (15%; 20 %) which was higher than that treated with Tannin and fertilizing solution, and the results also showed that eggs at the two treatments (T2 and T3) with Strawberry Juice , have a shorter period of incubation which was(66 and 64 hours)as compared with the control (71 hours to hatches at 22Cº).
