Evenson and published by . This book was released on 2018 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The salmon hatchery program in Alaska was initiated in the 1970s to rehabilitate depleted salmon fisheries. Learning from problems encountered with the robust hatchery programs in place in the Pacific Northwest, Alaska's program was envisioned and proactively designed to protect wild salmon stocks. Here we build upon a previous review of the precautionary plans, permits, and policies that have guided salmon enhancement in Alaska in a manner that protects wild stocks. These consist of development of rigorous permitting processes that includes genetics, pathology, and fishery management reviews; policies that require hatcheries to be located away from significant wild stocks; use of local brood sources; laws that give priority to wild stocks in fisheries; provisions for marking of hatchery fish; and as necessary, requirements for special studies on hatchery/wild stock interactions. Now that statewide annual production has largely stabilized, and amid rising concerns for effects on wild salmon populations, a review of the implementation of Alaska's precautionary approach is both timely and warranted. In this paper we explore procedures, practices, fishery management, and stock assessment relevant to the hatchery program for consistency with State of Alaska policies using two case studies--Southeast Alaska Chinook salmon and Prince William Sound pink salmon.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, salmon hatcheries in Southeast Alaska (SEAK) have reported humpback whales (Megaptera novaeangliae) feeding on juvenile salmon during and after their release in late spring and early summer. Given that the abundance of humpback whales in SEAK is increasing at a rate of about 5.1% a year, this predation is likely to become an increasing problem. To gain a better understanding of why some individual whales prey on hatchery-released salmon, I investigated the role of kinship in this feeding behavior. I hypothesized that salmon-feeders would be closely related (e.g., mother and offspring) if this specialized predation was influenced by maternal experience. I used behavioral observations, long-term sighting histories, and genetic samples of humpback whales observed near Hidden Falls Hatchery during and after their release of chum and coho salmon (Oncorhynchus keta and O. kisutch) in May 2014 to compare life-history characteristics and estimate relatedness between individuals who fed on salmon and those who did not. I found that of the 22 unique individuals encountered during the study, only four were confirmed to be feeding on hatchery-released salmon. Of these four, I considered two -- IDs 2227 and 2571 -- to be "hatchery-salmon specialists." These individuals were encountered repeatedly during the study feeding on hatchery-released salmon and shared an unusual pattern of feeding behavior. ID 2571 had no sighting history before 2014, but ID 2227 has been observed near Hidden Falls in multiple years since 2008, suggesting localized site fidelity. A kinship analysis based on DNA profiles indicated that IDs 2227 and 2571 are not closely related, suggesting either cultural inheritance of hatchery-salmon predation, or independent innovation. Long-term studies of humpback presence at multiple hatcheries could determine whether our results hold true over time and space. If hatchery-salmon predation continues to spread through cultural transmission, humpback whales could have a significant impact on hatchery production.

This book was released on 2016 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The salmon hatchery program in Alaska is governed by policies, plans, and regulations that emphasize protection of wild salmon stocks. A rotational series of hatchery evaluations will examine each hatchery for consistency with those policies and prescribed management practices. The evaluation includes a review of hatchery management plans and permits, an assessment of each hatchery program's consistency with statewide policies, and recommendations to address any deficiencies found. Management plans and permits were examined to determine whether they were current, consistent with each other, and accurately described hatchery operations. This report reviews the Port St. Nicholas salmon hatchery located in Craig, Alaska. The hatchery was constructed in 2005 by the Prince of Wales Hatchery Association, a private nonprofit aquaculture association. The hatchery serves as a central incubation site for release of Chinook salmon Oncorhynchus tshawytscha into Port St. Nicholas and Coffman Cove on Prince of Wales Island. The hatchery is also permitted to release chum salmon O. keta from Port Asumcion on Baker Island but has yet to do so. No broodstock is collected from Port St. Nicholas salmon hatchery returns. Eggs will be received in perpetuity from approved facilities in the region. A portion of the Chinook salmon releases are marked with coded wire tags and an adipose fin clip. Chum salmon will be thermal otolith marked. Chinook salmon are sampled in the commercial and sport fisheries to assess hatchery contribution. Streams near the release sites are monitored for Chinook salmon straying. Since the hatchery permit was issued in 2004, the basic management plan for the hatchery should be updated with the hatchery permit amendments made since then, including the Coffman Cove Chinook salmon program and the chum salmon program.

This book was released on 2015 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The salmon hatchery program in Alaska is governed by policies, plans, and regulations that emphasize protection of wild salmon stocks. This report reviews the Sheldon Jackson salmon hatchery located in Sitka, Alaska, for consistency with those policies and prescribed management practices. The hatchery was constructed in 1975 and permitted to Sheldon Jackson College, where it served primarily as an education component of the college. In 2010, Sitka Sound Science Center was permitted to operate the facility after Sheldon Jackson College closed. The hatchery continues to serve primarily as an education and research facility. The facility produces pink, coho and chum salmon. The even-year pink salmon ancestral stock is from the Indian River, as is the ancestral coho stock. The odd-year pink salmon stock originated from nearby Starrigavin River. The chum salmon ancestral stock is comprised of several donor stocks from rivers in Sitka Sound. These stocks have been produced at the hatchery since the late 1970s and have intermingled with Indian River stocks for about 3 decades. A portion of the coho salmon releases are marked with coded wire tags and adipose finclip. All pink and chum salmon are thermal otolith marked. Coho salmon are sampled in the commercial fisheries to assess contribution. Three area streams are monitored for straying. The basic management plan for the hatchery should be updated to reflect current hatchery operations. Egg take procedures should be reviewed to ensure egg-take numbers do not exceed permitted capacity. The need for sampling the Indian River escapement for hatchery strays should be reviewed in light of the integration of the hatchery and Indian River stocks since the 1970s.

Book excerpt: The salmon hatchery program in Alaska is governed by policies, plans, and regulations that emphasize protection of wild salmon stocks. A rotational series of hatchery evaluations will examine each hatchery for consistency with those policies and prescribed management practices. The evaluation includes a review of hatchery management plans and permits, an assessment of each hatchery program?s consistency with statewide policies, and recommendations to address any deficiencies found. Management plans and permits were examined to determine whether they were current, consistent with each other, and accurately described hatchery operations. This report reviews the Sheep Creek Salmon Hatchery (SCH) operated by the Douglas Island Pink and Chum Incorporated (DIPAC), a private nonprofit corporation. The facility is located in Gastineau Channel on the Juneau waterfront in Southeast Alaska. SCH was constructed by DIPAC in 1980 and is currently permitted to rear coho salmon Oncorhynchus kisutch, and pink salmon Oncorhynchus gorbusha.The original broodstock for chum, pink, and coho salmon were from several area stocks. Juvenile salmon hatched at SCH were released from the hatchery and several release sites near Juneau. Chinook salmon smolts incubated and reared at other Southeast Alaska hatcheries were released from SCH saltwater netpens. Hatchery operations were largely discontinued beginning in 1997. There is no egg incubation at the site today, but chum salmon incubated at Macaulay Salmon Hatchery (MSH) are reared and released from saltwater netpens at Sheep Creek. Chum salmon capacity at SCH was transferred to MSH in 2001. The current capacity for coho salmon at SCH is 150,000 eggs. The permitted capacity for pink salmon is uncertain from review of hatchery permitting documents. The basic management plan for SCH should be updated to reflect the current status of the hatchery and to clarify the current permitted pink salmon egg capacity.
