Some results of monitoring for the pink salmon hatchery stocks from the Aniva Bay (Sakhalin Island)
Several population parameters (length and dynamics of spawning run, size-sex composition, variability of morphological and physiological characteristics) are determined and indices of survival are calculated for the pink salmon hatchery stocks from the Aniva Bay of the 2008-2011 generations on the b...
