Historical δ15N records of Saccharina specimens from oligotrophic waters of Japan Sea (Hokkaido)
Historically Saccharina spp. beds occurred along the west coast of Hokkaido, an oligotrophic area, and were commercially exploited. Currently extensive commercial Saccharina spp. beds do not form due to nutrient limitations. Here, we postulate that nutrients assimilated by paleo-Saccharina spp. beds may have been derived from spawning herrings (Clupea pallasii) acting as organisms that formed a...
متن کاملAppendix 1I: Spawning Habitat Selection by Herring in Kamishak Bay, AK Statistical Analysis A total of 488,653 km of shoreline in Kamishak Bay, AK was surveyed for Pacific herring (Clupea pallasi) spawning events from fixed-wing aircraft in years
Statistical Analysis A total of 488,653 km of shoreline in Kamishak Bay, AK was surveyed for Pacific herring (Clupea pallasi) spawning events from fixed-wing aircraft in years 1978 – 2001, with the exception of 1982 and 1997. Every survey followed the same route. Although multiple surveys occurred in each year, the survey frequency was largely a function of weather, perceived size of the spawni...
متن کاملExxon Valdez Oil Spill Restoration Project Final Report Investigation of Pacific Herring (Clupea pallasii) Stock Structure in Alaska Using Otolith Microchemistry and Heart Tissue Fatty Acid Composition Restoration Project 070769 Final Report
Understanding the structure of Alaska’s Pacific herring stocks is relevant to how these exploited populations should be assessed and managed. We evaluated the capability of heart tissue fatty acid profiles and otolith microchemistry to identify the stock of origin for herring sampled from fourteen spawning aggregations associated with seven putative herring stocks throughout Alaska (e.g., Sitka...
متن کاملPacific and Atlantic herring produce burst pulse sounds.
The commercial importance of Pacific and Atlantic herring (Clupea pallasii and Clupea harengus) has ensured that much of their biology has received attention. However, their sound production remains poorly studied. We describe the sounds made by captive wild-caught herring. Pacific herring produce distinctive bursts of pulses, termed Fast Repetitive Tick (FRT) sounds. These trains of broadband ...
متن کاملEffects of Pleistocene climatic fluctuations on the phylogeographic and demographic histories of Pacific herring (Clupea pallasii).
We gathered mitochondrial DNA sequences (557 bp from the control region in 935 specimens and 668 bp of the cytochrome b gene in 139 specimens) of Pacific herring collected from 20 nearshore localities spanning the species' extensive range along the North Pacific coastlines of Asia and North America. Haplotype diversity and nucleotide diversity were high, and three major phylogeographic lineages...
