Description

Изобретение относитс  к рыборазве дению, в частности к способам предела устойчивости морских моллюсков к действию опреснени . Известен способ, заключанмцийс  в отлове моллюсков, приготовлении раст воров морской воды различной солености с заданными интервалами солености среди обитани , размещении в них неследуелых объектов, определении функ циональной активности объекта через определенные промежутки времени и графическом определении предела устойчивости. Дл  этого отлавливают моллюсков одного вида до 1000 штук, приготавливают растворы различной со лености с интервалом 2%, начина  от солености среды обитани  данного мол люска до 0% , ив каждую емкость с приготовленным раствором помещают до 100 штук исследуемых моллюсков. Чере 1 ч определ ют соленость, где моллюски сохран ют 100%-ную активность (об активности суд т по открытым створкам раковин моллюсков). Далее в вы вленной таким образом солености выдерживают (акклимируют) всех иссле дуемых моллюсков в течение двух недель , после чего их помещают в растворы различной солености с интервалом 2% от солености, в которой выдерживали моллюсков в течение двух недель, до 0% . Через 1 ч определ ют соленость -со 100%-ной активностью моллюсков, акклимируют в ней всех животных в течение двух недель и т.д. до тех пор, пока не определ т соленость , при которой моллюски утрачивают стопроцентную активность, т. е. Пока не достигают предела акклимации к низкой солености. По полученным даннЕЛч стро т график зависимости активности моллюсков от солености и определ ют нижнюю границу неповреждающих концентраций морской воды (предел УСТОЙЧИВОСТИ к действию опреснени ) 1. Так как согласно известному способу используют целые организмы моллюсков , осуществление способа требует большого количества моллюсков одного вида, длительного времени (от одного до трех мес цев), больших производственных площадей дл  размещени  емкостей с разными растворами соленостей . Цель изобретени  - уменьшение трудоемкости процесса определени  . предела устойчивости морских.модлюсков к действию опреснени .The invention relates to fish retrieving, in particular, to methods for limiting the resistance of marine mollusks to the action of desalination. The known method consists in capturing mollusks, preparing sea water of different salinity with given salinity intervals among the habitats, placing non-next objects in them, determining the functional activity of the object at certain time intervals and graphically determining the stability limit. For this, mollusks of the same species are caught up to 1000 pieces, solutions of different salinity are prepared with an interval of 2%, starting from the salinity of the habitat of this mollusk to 0%, and up to 100 pieces of the studied mollusks are placed in each container with the prepared solution. After 1 h, the salinity is determined, where the mollusks retain 100% activity (activity is judged by the open valves of the shells of mollusks). Then, in the salinity thus detected, they were kept (acclimated) for all the studied mollusks for two weeks, after which they were placed in solutions of different salinity with an interval of 2% of the salinity, in which they were kept for two weeks, to 0%. After 1 h, the salinity is determined with the 100% activity of the mollusks, all animals are acclimated therein for two weeks, and so on. until the salinity is determined, at which the mollusks lose one hundred percent activity, i.e. until they reach the limit of acclimation to low salinity. Using the obtained data, a graph is constructed of the dependence of the activity of mollusks on salinity and the lower limit of non-damaging concentrations of seawater is determined (limit of RESISTANCE to the action of desalination) 1. Since, according to a known method, whole organisms of mollusks are used, the implementation of the method requires a large number of mollusks of the same type for a long time (from one to three months), large production areas to accommodate tanks with different salinity solutions. The purpose of the invention is to reduce the complexity of the determination process. Limit of the stability of marine moduli to the action of desalination.
