Book Southeast Alaska 2019 Herring Stock Assessment Surveys

Download or read book Southeast Alaska 2019 Herring Stock Assessment Surveys written by Kyle Peter Hebert and published by . This book was released on 2020 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific herring Clupea pallasii are important prey for many marine species found in Southeast Alaska and are harvested in commercial fisheries (bait, sac roe, spawn-on-kelp), and for subsistence, personal use, and research purposes. The Southeast Alaska Herring Management plan (5 AAC 27.190(3)) requires the Alaska Department of Fish and Game to assess the abundance of mature herring for each stock before allowing commercial harvest. Included here are results of stock assessment surveys completed primarily during 2019, including summaries of herring spawn deposition surveys and age-weight-length sampling, which are the principle model inputs used to forecast herring abundance. In 2019, spawn deposition surveys were conducted only for Sitka Sound, Craig, and Revilla Channel area stocks. Spawn deposition surveys were not conducted in several other traditionally major spawning areas due to lack of funding, although aerial surveys of spawning were continued on a limited basis. The shoreline in state waters where spawn was documented during aerial surveys in 2019, combined for all areas, was 111.0 nautical miles. Post-fishery spawn deposition biomass estimates, combined for all surveyed stocks, totaled 169,514 tons. During the 2018–2019 season, a commercial winter bait fishery was opened in Craig with a guideline harvest level (GHL) of 2,344 tons. A commercial purse seine sac-roe fishery was planned in Sitka Sound with a GHL of 12,869 tons; however, no openings were announced due to high abundance of young/small herring that were below desired marketable size. A commercial spawn-on-kelp fishery was open in Craig with an allocation of 2,911 tons of herring. There were no other commercial fisheries opened in 2019. Herring harvested commercially during the 2018–2019 season totaled 995 tons, not including herring pounded for spawn-on-kelp fisheries or spawn-on-kelp products.

Available in PDF, EPUB and Kindle. Book excerpt: Pacific herring Clupea pallasii are important prey for many marine species found in Southeast Alaska and are harvested in fisheries for subsistence, personal use, commercial, and research purposes.

In 2020, spawn deposition surveys were conducted only for Sitka Sound, Craig, and Revilla Channel area stocks. Spawn deposition surveys were not conducted in several other traditionally major spawning areas due to lack of funding or low levels of observed spawn, although aerial surveys of spawning were continued on a limited basis. The shoreline in state waters where spawn was documented in Southeast Alaska during aerial surveys in 2020, combined for all areas, was 142.6 nautical miles. Post-fishery spawn deposition biomass estimates, combined for all surveyed stocks, totaled 412,794 tons. During the 2019–2020 season, a commercial winter bait fishery was opened in Craig with a guideline harvest level (GHL) of 6,608 tons. A commercial purse seine sac-roe fishery was planned in Sitka Sound with a GHL of 25,824 tons; however, no fishery openings were announced due to high abundance of young, and therefore small, herring that were below desired marketable size. A commercial spawn-on-kelp fishery was open in Craig with an allocation of 10,118 tons of herring, allowing for the highest kelp allocation for pounds. There were no other commercial fisheries opened in 2020. Herring harvested commercially during the 2019–2020 season totaled 896 tons, not including herring pounded for spawn-on-kelp fisheries or spawn-on-kelp products.

Book Age Structured Analysis of Pacific Herring from Norton Sound  Alaska

Download or read book Age Structured Analysis of Pacific Herring from Norton Sound Alaska written by Erik H. Williams and published by . This book was released on 1996 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Age-structured assessment models are used for many exploitable herring stocks in Alaska in order to forecast the abundance of returning herring. The purpose of this study is to determine if an age-structured assessment model could be developed for Norton Sound herring. Commercial catch and sampling data for Norton Sound herring were obtained from the Alaska Department of Fish and Game. Natural mortality estimates were obtained from analysis of life history parameters. Initial starting values for the age-structured model weere obtained from cohort analysis. Two types of models, with and without a pooled age group, were fit to the data. A parametric bootstrap analysis utilizing a beta distribution fit to observed age compositions was performed in order to obtain standart deviations of the estimates. Model fits indicated that inclusion of a pooled age group (10+) worked best. The fit of this model to the data is comparable to previous age-structured assessments of Alaska herring stocks." -- from the Abstract.
