“…The fish species that are present in these habitats include those of subsistence importance such as whitefishes, Dolly Varden, Pacific salmon, cods (Gadidae), and flounder species (Pleuronectidae). Additionally, taxa such as sculpins (Cottidae), stickleback (Gasterosteidae), and Pond Smelt Hypomesus olidus, among others, occur in these habitats and are ecologically important as prey for predatory fishes, birds, and marine mammals that are of subsistence importance (Quakenbush et al 2015;Whitehouse and Buckley 2017;Naves 2018).…”

Energy Condition of Subsistence‐Harvested Fishes in Arctic Coastal Lagoons

In Arctic Alaska, Indigenous and rural residents depend on wildharvested foods for sustenance and the subsistence lifestyle is integral to their culture. Marine and diadromous fishes, which often occupy coastal lagoon habitats, are relied upon for subsistence harvest, particularly Pacific salmon, whitefishes (Coregoninae), cods (Gadidae), and flounder species (Pleuronectidae). However, little research has been conducted that assesses the energetic condition of these fishes, which are harvested by the tens of thousands annually. The effects of accelerating climate change and human development on the metabolic rates, diet, body condition, and energy density of fish is of great concern because these effects will, in turn, affect the people who depend on these species for food security. Consequently, we characterized energy density and percentage of lipid, water, and protein content of 10 fish species in four coastal lagoons within Cape Krusenstern National Monument, Alaska. We found that whitefishes, particularly Bering Cisco Coregonus laurettae and Least Cisco C. sardinella exhibited the highest energy density, percentage of lipid, and percentage of protein content, significantly greater than that of marine cod and flounder species, Fourhourn Sculpin Myoxocephalus quadricornis, freshwater Pond Smelt Hypomesus olidus, and values from other regional species that have been in published literature. Additionally, when the relative mean abundance and body weight of each species was taken into account, total energy value by availability in the lagoons was highest for whitefishes when compared with marine taxa and the freshwater Pond Smelt. Given the impending effects of climate change and coastal construction in the region, it will be important to monitor the energy condition of lagoon fishes to ensure their quality and availability for subsistence harvesters.

“…Nonetheless, hunting of seabirds at colonies is still considered to be the second largest threat on land in terms of number of species affected, and the top threat to coastal species that are globally threatened (Dias et al 2019). For instance, traditional hunting of seabirds and egg harvesting is still a common practice in the Arctic where this resource can be fundamental (Naves 2018;Renner and Huntington 2014). Additionally, because many seabirds are longdistance migrants, multiple breeding populations over a wide area could be impacted by local hunting during the non-breeding season, as demonstrated recently for Thickbilled Murre Uria lomvia, with local hunting pressure in West Greenland and Eastern Canada during winter affecting growth rates, and potentially causing declines in populations from Svalbard to Canada (Frederiksen et al 2019).…”

“…Traditional people in Africa, Asia, Northern Europe, and the Americas have harvested wild bird eggs for collection or consumption for centuries (Abernethy et al 2013, Swamy and Pinedo-Vasquez 2014, Naves 2015, Mondretii et al 2018, FAO/UNEP 2020, Gallo-Cajiao et al 2020. Similarly, the eggs of megapodes are a popular source of protein in the Pacific region (Dekker 1991, Jones et al 1995, Steadman 1999, Anderson et al 2010.…”

Summary Traditional policies on using wild species are critical in developing scenarios for community engagement in conserving wild species populations. As such, this study examines the traditional practice of harvesting eggs from Moluccan Scrubfowl Eulipoa wallacei on Haruku Island, Indonesia, and its implications for bird population conservation. Using a closed-ended questionnaire, we surveyed 200 respondents in the productive age group (aged 15–65 years). It was found that most of the community supported adopting the traditional policies due to the high demand for eggs, which required daily harvesting. According to the community, egg harvesting has no adverse effect on bird populations, but hunting and habitat destruction does reduce the number of eggs available for harvesting. The community concluded that traditional conservation policies prioritise the conservation of adult birds and their habitats, not bird eggs. Particular attention should be paid to egg conservation efforts by establishing a quota for egg harvesting and limiting egg-harvesting time. Conservation efforts must also take into account the growing community awareness of the importance of conserving Moluccan Scrubfowl eggs.
