Abstract Wild capture fisheries produce 90 million tonnes of food each year and have the potential to provide sustainable livelihoods for nearly 40 people around world ( http://www.fao.org/3/a-i5555e.pdf ). After decades overfishing since industrialization, many global fish stocks recovered, a change brought about through effective management. We synthetic overview three approaches that managers use sustain stocks: regulating catch fishing mortality, effort spatial access. Within these...
Managed aquifer recharge (MAR) is typically used to enhance the agricultural water supply but may also be promising maintain summer streamflows and temperatures for cold-water fish. An existing model, temperature data, analysis of administration were assess potential benefits MAR fisheries in Idaho’s Snake River. This highly-regulated river supports irrigated agriculture worth US $10 billion recreational trout $100 million. The assessment focused on Henry’s Fork River, which receives...
In Mekong riparian countries, hydropower development provides energy, but also threatens biodiversity, ecosystems, food security, and an unparalleled freshwater fishery. The Sekong, Sesan, Srepok Rivers (3S Basin) are major tributaries to the Lower River (LMB), making up 10% of watershed supporting nearly 40% fish species LMB. Forty-five dams have been built, under construction, or planned in 3S Basin. We completed a meta-analysis aquatic environmental losses from current, planned, proposed...
Abstract Reservoirs are sometimes managed to meet agricultural and other water demands, while also maintaining streamflow for aquatic species ecosystems. In the Henrys Fork Snake River, Idaho (USA), irrigation‐season management of a headwater reservoir is informed by flow target in reach ~95 km downstream. The place irrigation demand maintain habitat within 11.4 has undergone four assignments from 1978 2021. Recent changes maximize carryover warranted investigation into assignment. Thus, we...
Agricultural irrigation practices have changed through time as technology has enabled more efficient conveyance and application. In some agricultural regions, can contribute to incidental aquifer recharge important for groundwater return flows streams. The Henrys Fork Snake River, Idaho (United States) overlies a portion of the Eastern Plain Aquifer, where irrigated agriculture occurred over century. Using irrigator interviews, aerial satellite imagery, statistical streamflow analysis, we...
Availability of water for irrigated crops is driven by climate and policy, as moderated public priorities opinions. We explore how policy interact to influence availability cannabis (Cannabis sativa), a newly regulated crop in California, well discourse frames these interactions. Grower access surface covaries with precipitation frequency oscillates consistently an energetic 11–17 year wet-dry cycle. Assessing contemporary policies against historic streamflow data showed that legal was most...
Abstract Lower Granite Dam is the last dam that federally protected Snake River salmonids Oncorhynchus spp. must ascend during their spawning migration. The has an adult fish ladder equipped with a trapping system to facilitate fisheries research and hatchery broodstock collection. There are three possible passage routes through ladder: trapped, shunted, free passage. During season, all swim 0.305-m shunt pipes outfitted PIT tag arrays allow selection of for trapping. Selected use “trapped”...
Abstract Groundwater return flow to streams is important for maintaining aquatic habitat and providing water downstream users, particularly in irrigated watersheds experiencing scarcity. However, many agricultural regions, increased irrigation efficiency has reduced flows their subsequent in‐stream benefits. Agricultural managed aquifer recharge (Ag‐MAR)—where artificial conducted via canals fields—may be a tool recover these flows, but implementation challenged by supply management. Using...
