Pacific herring, Clupea pallasii, is important to many marine species found in Southeast Alaska and is also harvested in fisheries for commercial bait, commercial sac roe, commercial spawn-on-kelp, subsistence spawn-on-branches, subsistence spawn-on-kelp, personal use, and research/cost-recovery 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 2016, including summaries of herring spawn deposition surveys and age-weight-length sampling, which are the principle model inputs used to forecast herring abundance. In 2016 spawn deposition surveys were conducted in Sitka Sound, Craig, Ernest Sound, Seymour Canal, and Lynn Canal. Spawn deposition surveys were not conducted in several other major spawning areas in 2016, due to either lack of funding or little or no observed spawn. The total cumulative shoreline in state waters where spawn was documented during aerial surveys in 2016, combined for all areas, was 104.8 nautical miles. In 2016, post-fishery spawn deposition biomass estimates, combined for all surveyed stocks, totaled 86,357 tons. During the 2015-2016 season, a commercial winter bait fisheries was opened in Craig with a guideline harvest level of 954 tons. A commercial purse seine sac-roe fishery was opened in Sitka Sound with a guideline harvest level of 14,741 tons. A commercial spawn-on-kelp fishery was open in Craig, with an allocation of 692 tons. There were no commercial gillnet fisheries opened in 2016. No commercial fisheries were opened in Seymour Canal, Hobart Bay-Port Houghton, Hoonah Sound, Tenakee Inlet, West Behm Canal, Kah Shakes/Cat Island, or Lynn Canal. Herring harvested commercially during the 2015-2016 season totaled just over 10,700 tons, not including herring pounded for spawn-on-kelp fisheries

In 2017 spawn deposition surveys were conducted in Sitka Sound, Craig, and Seymour Canal. Spawn deposition surveys were not conducted in several other major spawning areas in 2017, primarily due to lack of funding resulting from cuts to state budgets. The shoreline in state waters where spawn was documented during aerial surveys in 2017, combined for all areas, was 107.5 nautical miles. In 2017, post-fishery spawn deposition biomass estimates, combined for all surveyed stocks, totaled 71,011 tons. During the 2016-2017 season, a commercial winter bait fisheries was opened in Craig with a guideline harvest level of 523 tons. A commercial purse seine sac-roe fishery was opened in Sitka Sound with a guideline harvest level of 14,649 tons. A commercial spawn-on-kelp fishery was open in Craig, with an allocation of 349 tons. There were no commercial gillnet fisheries opened in 2017. No commercial fisheries were opened in Seymour Canal, Hobart Bay-Port Houghton, Hoonah Sound, Tenakee Inlet, West Behm Canal, Kah Shakes/Cat Island, or Lynn Canal. Herring harvested commercially during the 2016-2017 season totaled just over 14,450 tons, not including herring pounded for spawn-on-kelp fisheries.

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. 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 2020, including summaries of herring spawn deposition surveys and age-weight-length sampling, which are the principal model inputs used to forecast herring abundance. 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.

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.
