• The catch per net per hour was taken as a measure of the rate of immigration of salmons to Voroskaya fishing ground, West Kamchatka. Daily serial observations of the temperature, salinity and transparency of sea-water were carried out at every mile on a line extending 5 miles from the shore. Salmons were found to immigrate most abundantly to this fishing ground, when the temperature is 10° to 13°C, salinity is less than 29.8‰, and transparency is small near the shore but great in the offing.
