This book was released on 1984 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of adult Pacific herring (Clupea harengue pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by depth and geographic area over 24 successive months during 1973-75. From June through September, schools concentrated at 5- to 37-m depths where zooplankton was abundant, and moderate currents were present in a stratified water column. The schools migrated from this area to wintering grounds in October when windstorms and sinking of cooling surface waters broke up stratification, day length shortened, and food abundance declined drastically. The schools remained near bottom in the deeper parts of the wintering grounds at 52- to 85-m depths into February or March when day length had increased, but temperatures and food abundance remained low. At this time, the herring left the wintering grounds and moved up Lynn Canal to areas near spawning beaches. Pacific herring remained in these areas until water temperatures increased and plankton blooms appeared in late April and May, at which time the fish moved into the shallows and spawned. By early summer, the schools gradually concentrated again on the main feeding grounds. An evaluation of the study design and potential for improvements in similar studies is included.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
