Изобретение относитс к области рыборазведени , в частности к способам консервировани спермы рыб, преимущественно карповых рыб, и может найти применение на рыборазводных заводах.The invention relates to the field of fish farming, in particular to methods of preserving semen of fish, mainly carp fish, and can be used in fish breeding plants.
Известный способ консервировани спермы рыб заключаетс в смешивании ее с защитным раствором, содержащим трис- НС1-буфер., этиленгликоль или пропиленгликоль , и в последующем замораживании.A known method of preserving fish sperm is to mix it with a protective solution containing Tris-HCl buffer, ethylene glycol or propylene glycol, and then freeze it.
Известный способ имеет недостаток, заключающийс в том, что размороженна сперма полностью утрачивает свою оплодотворительную способность.The known method has the disadvantage that the unfrozen sperm completely loses its fertilizing ability.
Целью данного изобретени вл етс повышение сохранности оплодотвор ющей способности спермы.The purpose of this invention is to increase the safety of the fertilizing ability of sperm.
Дл достижени цели в защитный раствор ввод т поливиниловый спирт, иодид серебра и маннитол, а замораживание осуществл ют сначала со скоростью 5-10°С /мин до температуры -12 -20°С, а затем со скоростью 15-25°С/мин до температуры -196°С.To achieve the goal, polyvinyl alcohol, silver iodide and mannitol are introduced into the protective solution, and freezing is carried out first at a rate of 5-10 ° C / min to a temperature of -12 -20 ° C, and then at a rate of 15-25 ° C / min to a temperature of -196 ° C.
Кроме того, компоненты защитного раствора берут в следующем соотношении: трис-НС1-буфер-0,1-0,2 М, маннитол- -0,14-0,15 М, поливиниловый спирт- -0,05-0,1 М в расчете на элементарноеIn addition, the components of the protective solution are taken in the following ratio: Tris-HC1-buffer-0.1-0.2 M, mannitol- -0.14-0.15 M, polyvinyl alcohol- -0.05-0.1 M counting on the elementary
звено полимера, иодид серебра -0,001 - 0,1 М, этиленгликоль - 2,2-2,8 М.polymer unit, silver iodide -0.001 - 0.1 M, ethylene glycol - 2.2-2.8 M.
Данный способ осуществл ют следующим образом.This method is carried out as follows.
К чистой сперме карпа (без примесей воды , гр зи и фекалий) с активностью 80- 100% приливают раствор, содержащий трис-НС1-буфер, маннитол, поливиниловый спирт, иодид серебра и этиленгликоль.A solution containing Tris-HCl buffer, mannitol, polyvinyl alcohol, silver iodide and ethylene glycol is added to a pure carp semen (free of water, dirt and feces) with an activity of 80-100%.
После размешивани полученную смесь дозируют в виде капель весом 50-100 мл и замораживают в парах азота до -12- -20°С со скоростью 5-10°С/мин, а затем со скоростью 15-25°С/мин до - 196°С.After stirring, the mixture is dosed in the form of droplets weighing 50-100 ml and frozen in nitrogen vapor to -12- -20 ° C at a rate of 5-10 ° C / min, and then at a rate of 15-25 ° C / min to - 196 ° s
Пр и мер: К 4,5 мл чистой спермы карпа с активностью 85% прилили 5,5 мл раствора , содержащего 0,15 М трис-НС1-буфера , 0,149 М маннитола, 0,075 М поливинилового спирта в расчете на элементарноеPr and measures: To 4.5 ml of pure carp sperm with an activity of 85% poured 5.5 ml of a solution containing 0.15 M Tris-HCl buffer, 0.149 M mannitol, 0.075 M polyvinyl alcohol per elemental
звено полимера, 0,005 М иодида серебра и 2,336 М этиленгликол .a polymer unit, 0.005 M silver iodide and 2.336 M ethylene glycol.
После размешивани полученную смесь дозировали в виде капель весом 50 мл и замораживали в парах азота со скоростьюAfter stirring, the mixture was dosed in the form of droplets weighing 50 ml and frozen in nitrogen vapor at a rate of
5°С/мин до - 15°С, а затем со скоростью 15°С/мин до -196°С.5 ° С / min to –15 ° С, and then with the speed of 15 ° С / min to -196 ° С.
Технико-экономический эффект способа получаетс в сохранении 50% оплодотвор ющей способности спермы рыб.The technical and economic effect of the method is obtained in preserving 50% of the fertilizing ability of fish sperm.
