Masu salmon Oncorhynchus masou is the most thermophilic species among the Pacific salmon, and Kamchat-ka peninsula is the northern border of its distribution. Due to small abundance, the biology of this species on the peninsula is poorly studied. Regular scientific researches of Masu salmon in Kamchatka have been con-ducted since 2009. The length-weight structures and fecundity of mature Masu salmon have been analyzed in several streams on western Kamchatka over a 10-year period (from 2009 to 2018) and present time. It has been established that the length, weight and fecundity of mature fish are different in the rivers of the peninsula. A tendency of increasing the biological characteristic of the species in recent years has been noted.

Masu Salmon Oncorhynchus Masou

In South Primor'e (Russia), mature male masu salmon (Oncorhynchus masou) parr are found at age 0 + to 3 + (9–22 cm). After first maturation, some male parr die, while others survive and mature the following year. Immature males become smolts after one or two winters in rivers and migrate to the sea in spring–early summer. After one winter in the sea, they return as sea-run normal-sized (40–70 cm) males at age R.1 +. Besides mature male parr and normal-sized sea-run males, jacks (28–33 cm) at age R.0 + were found. Such males return to rivers after some months of marine life and do not overwinter in the sea. Some jacks previously spawned as parr, while others did not. All jacks and normal-sized sea-run males die after spawning. Thus, male masu salmon mature as one of four life history forms: (1) male parr, (2) jacks that matured previously as parr, (3) jacks that did not mature previously as parr, and (4) ordinary sea-run males. While mature male parr and sea-run males are ordinary life history forms, both forms of jack are rare.
