| Popis: | The issues related to specific traits of the life cycle and formation of the life history strategy diversity in fishes are urgent at present for optimization of the use of biological resources. Recently, the problems in the field of retrospective deciphering of the life cycle are being solved by methods of microchemical analysis of otoliths. These techniques determine the presence of marine, estuarine, or freshwater periods in the ontoge� nesis with sufficient accuracy [1–4]. These methods are based on direct dependence of accumulation of ions of elements in fish otoliths corresponding their content in the environment, e.g. the content of stron� tium in seawater is much higher than in fresh water. The efficiency of methods of “otolith microchemitry” was repeatedly confirmed in various teleostean groups [2–9]. At the same time, most methods of otolith analysis deciphering the life history strategy in fish |
