Herring spawning surveys in southeastern Alaska / by Bernard Einar Skud.
Aerial surveys to observe milt clouds produced by spawning herring in southeastern Alaska waters hold promise as a method for assessing the extent of spawn deposition. Flights are conducted at altitudes of 500 to 700 feet and at cruising speeds of 120 knots. The mileage of beach utilized for spawnin...

| 520 | |a Aerial surveys to observe milt clouds produced by spawning herring in southeastern Alaska waters hold promise as a method for assessing the extent of spawn deposition. Flights are conducted at altitudes of 500 to 700 feet and at cruising speeds of 120 knots. The mileage of beach utilized for spawning is recorded on reduced prints of navigation charts. The surveys have resulted in the discovery of 80 previously unreported spawning beaches. Observations during these preliminary flights have also added valuable information on the time of spawning and the physical characteristics of the beaches. | ||
