Postharvest Losses Along the Small‐Scale Fish Value Chain in Bangladesh: Perceptions, Determinants and Implications for Food Security

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Postharvest fish losses in Bangladesh remain substantial (about 10% for farmers and 12% for traders), driven by high temperatures, inadequate storage, poor handling practices, and market inefficiencies. Strengthening education and training, improving cooling practices, and enhancing transport and market access can significantly reduce these losses ...

Centring care as part of Indigenous environmental stewardship: Collective learning through cultural plants

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1349-1361, May 2026.
Abstract Stewardship is broadly defined as ‘universal responsibility of humanity to care for the planet, to ensure that it can continue to provide the essential natural resources for life’. Stewardship practices shape ecosystems, create diverse biocultural landscapes, and can enhance the productivity, availability and health of plants used by ...

Efficiency of gillnets with 170mm mesh size in reduction of immature Persian sturgeon, Acipenser persicus, catch

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2011
This study was carried out in Turkmen fishing station to examine suitable mesh size of gill nets for Persian sturgeon, Acipenser persicus, to decrease possibility of catching immature specimens and increase catch likelihood for larger fish.

Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 796-811, May 2026.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 837-850, May 2026.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

A Method to Implement Natural Flow Regimes for Regulated Rivers

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Rivers throughout the world have been dammed for flood control, irrigation, hydropower, and water storage for centuries. Dams service the economic and development needs of societies, but degrade the ecology of rivers. To conserve diminishing aquatic species and their habitats, methods are needed to help managers implement flow releases with ...

Refinement of a Framework for Moving Aircraft River Velocimetry (MARV) and Application to Particle Tracking Along Alaskan Rivers

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

Predicting Historical Populations and Evaluating Shifting Baselines of Traditionally Exploited Fisheries

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 506-518, May 2026.
ABSTRACT Development of data‐intensive stock assessment and ecosystem‐based models has improved our understanding of shifting species abundance in response to fishing, ocean ecology, and species interactions. Along with this analytical progress is evidence that many stocks lack data required for complex models, resulting in data‐limited options for ...
