Zusammenfassung:The invention relates to the pisticulture, particularly, to the process for increasing the fish resistance in early development stage.Summary of the invention consists in the fact that the fecundated fish spawn is treated with the biologic active, as a biologic active substance there is used the copper, zinc and manganese microelements water solution in the dose of 50...75 µg/l each.The technical result consists in increasing the larvae and recent fries yield and resistance thereof. Invenţia se referă la piscicultură, în special la un procedeu de sporire a rezistenţei biologice a peştilor la etapele timpurii de dezvoltare.Esenţa invenţiei constă în aceea că icrele fecundate de peşte se tratează cu o substanţă biologic activă, în acest scop servind soluţia apoasă de microelemente: cupru, zinc şi mangan în doză de 50...75 µg/l fiecare.Rezultatul tehnic este mărirea numărului de larve şi puieţi şi sporirea rezistenţei lor. Изобретение относится к рыбоводству, в частности к способу повышения жизнестойкости рыб на ранних стадиях развития.Сущность изобретения заключается в обработке оплодотворенной икры рыб биологически активным веществом в качестве которого используют водный раствор микроэлементов: меди, цинка и марганца в дозах по 50...75 мкг/л каждого.Технический результат - увеличение выхода личинок и сеголетков и повышение их устойчивости.
