This annual report reviews Alaska’s salmon fisheries enhancement program. This program’s success is attributable to the development of statutes, regulations, and policies that require hatcheries to be located away from important natural salmon stocks and to use local broodstock sources. To maintain genetic diversity, Alaska hatcheries do not selectively breed for size or other traits and use large numbers of broodstock. Most hatchery releases are marked so that fishery managers can estimate the strength of wild stocks in the harvest inseason and manage wild stocks conservatively. Hatchery production is intended to supplement—not replace—wild stock production. Harvests in 2013, 2015, and 2017 were 3 of the 4 highest wild stock salmon harvests dating back to the late 1800s. Abundance-based wild stock management priority, habitat protection, and record wild stock harvests reflect the state’s commitment to conservation of wild stocks and provide the foundation of its salmon fisheries enhancement program. Currently, 30 salmon hatcheries are operating in the state. Twenty-six facilities are operated by private nonprofit (PNP) corporations, which are funded primarily from the sale of a portion of hatchery returns. Of these, 11 are state owned and operated by PNPs on the state’s behalf at no cost to the state. Non-PNP operated hatcheries include two sport fish hatcheries operated by the state, one research hatchery operated by the National Marine Fisheries Service, and one hatchery operated by the Metlakatla Indian Community under federal regulation. In 2022, the commercial fleet caught 40 million Alaska hatchery-produced salmon worth an estimated $163 million in exvessel value. Hatchery fish contributed 25% of the statewide commercial salmon harvest and 23% of the statewide commercial harvest exvessel value. Additionally, 168 thousand hatchery fish were caught in sport, personal use, and subsistence fisheries. In preparation for future production, Alaska hatcheries took 2.1 billion salmon eggs and released 1.9 billion juvenile salmon.

Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

An additional 220 thousand Alaska hatchery fish were caught in the sport, personal use, and subsistence fisheries. In preparation for future production, Alaska hatcheries took 2.1 billion salmon eggs and released 1.7 billion juvenile salmon.
