Available in PDF, EPUB and Kindle. Book excerpt: Underwater dive surveys of deposited eggs and acoustic techniques were used to estimate the 1996 adult spawning population of Pacific herring Clupea pallasi in Prince William Sound (PWS). The spawn deposition estimate of the spawning biomass of herring was 25,101 tonnes with a 95% confidence interval ranging from 13,039 to 37,163 tonnes. This project also evaluated the feasibility of using acoustic echointegration techniques to estimate herring biomass immediately prior to spawning. However, all herring known to be in the area were not surveyed because herring had moved into shallow water and began to spawn while the survey was being conducted. Future acoustic surveys will be conducted earlier in the season to avoid this problem. Egg loss of PWS herring was studied during spawn deposition surveys in 1990, 1991, 1994, and 1995. The proportion of eggs lost through physical removal and mortality was investigated to improve diver survey biomass estimates and understanding of the mechanisms controlling early life history survival. Results indicated that egg loss rates are highly variable, site specific and are generally higher than previously estimated. Depth of spawn deposition and wave exposure accounted for much of the variation in instantaneous egg loss rates in the Montague Island area.

Download or read book Spawning Habitat Characteristics of Pacific Herring (Clupea Pallasii) in Prince William Sound, Alaska written by Brandee Lynn Gerke and published by . This book was released on 2002 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Spawning habitats of Pacific herring in Prince William Sound, Alaska were analyzed to determine the importance of habitat features including vegetation type, percent vegetative cover, substrate type, water depth, and shoreline slope in the importance of herring spawning ground selection. Sidescan sonar data were used to compare bottom habitat characteristics of herring spawning areas vs. non-spawn areas. No significant differences in vegetation or substrate type were detected between areas where herring do and do not spawn. Generalized linear models and analysis of variance models were constructed to predict the probability of herring spawn and estimate egg densities given habitat information collected by the Alaska Department of Fish and Game during herring egg deposition surveys. Habitat characteristics explained 31 % of the deviance in spawn presence and absence and 28% of the variability in egg densities. Vegetation type was the most important variable in determining the presence of spawn and vegetative percent cover was the most important variable in determining the intensity of herring spawn. Herring spawned most often on brown and red filamentous algae and red foliose algae. Egg densities increased with increasing percent vegetative cover. Spawning occurred most frequently in the shallow subtidal zone from 0 - 4 m"--Leaf iii.

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.
