COMPLEX MONITORING OF SALMON SPAWNERS ESCAPEMENT TO THE KAMCHATKA RIVER IN REAL TIME REGIME
Complex method of quick quantitative evaluation of the spawners escapement to the Kamchatka River is developed for pacific salmons on the base of analysis of their passing dynamics through certain parts of the river (main stream, tributaries, spawning grounds). The runs of different temporal forms o...
