Economic Dynamics and Informationt, but the mechanisms underlying such orderliness remain unclear [43, 51]. Investigations of temporal patterns in development have been limited until recently by the fact that the duration of any developmental period is a variable depending on a species-specific rate of development and, in poikiloth

They are also good for experimental embryological studies since they are highly resistant to unfavorable conditions; in this respect the Russian sturgeon is of special interest, as its viability markedly exceeds that of not only teleosteans but also other sturgeons studied, namely

It has become especially popular (partially due to its ever-increasing use in pisciculture) during recent decades: the bibliography [157] on the reproduction of some salmonid species during the period from 1963 to 1979 has 1399 references; they concern only the development of gonads, ovulation,

In the first half of this century experiments were carried out on eggs collected from natural spawnings.
