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.
