The amur pike (Esox reicherti Dybowski) in Fishes of the Amur Basin (results of the Ichthylogical Expedition to the Amur Region, 1945-1949 by G. V. Nikolsky, 1956) (Fisheries research report: 1787)

Basic equipment for catching pike and other fish is "zakidnie nevoda"
(seines). Small amounts of pike are caught with stavnaia seta
(shutter net). Other fishing devices do not play a significant role in
pike catches.
As a food product Amur pike do not differ considerably in
quality from European and American pike. Comparative data can be
seen in Table 6. Data are given by I. V. Kizevetter (1942) and
represent content of fats, moisture, proteins and ash in the flesh of
Amur, Astrahan and American pike. The presented data show regular
differences only in quantities of fats in muscles. Amur pike have nearly
two times more fat than Astrahan or American pike. The Amur pike is
prepared as a salty product or it is canned. Considerable part is utilized
as a fresh food.
Dynamics of pike population and means
of its reproduction
As seen in the tables presented, catch of pike in the Amur
region had a peak in 1937; after that the catch started decreasing and
continued to decrease until 1945-1946. According to Bogoaevsky,
decrease in catch was followed with decrease of average size of fish
caught. However, change of average size of fish cannot be caused only
by the influence of exploitation, but is also a result of strong management and stocking.
Amur pike, as a phytophil fish, spawn on vegetation. Years
with low spring water level are unfavorable for spawning. Concentrations
