Computer Vision Detects an Association Between Gross Gill Score and Ventilation Rates in Farmed Atlantic Salmon (Salmo salar)

Journal of Fish Diseases, EarlyView.
ABSTRACT Poor gill health compromises the health and welfare of farmed Atlantic salmon (Salmo salar) by causing respiratory distress and increased ventilation frequency. Poor gill health is caused by numerous factors, including amoebic gill disease (AGD), jellyfish stings, and toxic algae, and is monitored by fish farmers by manual ‘gill scoring’. Gill

Influence of trace metal additions on the longevity of algal blooms across a productivity gradient

Journal of Phycology, EarlyView.
Abstract Phytoplankton require specific nutrients in varying quantities for growth, defense, and proper cell functioning. When macronutrients are present in excess, trace metals can exhibit co‐limitation on phytoplankton. This experiment aimed to understand how ambient nutrient concentrations impact phytoplankton community persistence (i.e., bloom ...

Sewage-and fertilizer-derived nutrients alter the intensity, diversity, and toxicity of harmful cyanobacterial blooms in eutrophic lakes

Frontiers in Microbiology
Cyanobacterial harmful algal blooms (CHABs) are promoted by excessive nutrient loading and, while fertilizers and sewage are the most prevalent external nutrient sources in most watersheds, the differential effects of these nutrient sources on CHABs are ...

The Impact of Sustainable Nitrogen Management on the Health Risks of Unsafe Drinking Water and the Mediating Role of Food Production

Review of Policy Research, EarlyView.
ABSTRACT This study adopts a policy‐centric perspective to explore the complex relationship between sustainable nitrogen management (SNM) and the health risks associated with unsafe drinking water. The critical policy challenge lies in balancing the essential role of nitrogen fertilizers in achieving high agricultural productivity with their ...

Planning for the future, algae bloom dynamics in water management and ecosystem restoration efforts

Frontiers in Water
Eutrophication and chronic harmful algal blooms (HABs) are a challenge for ecosystem managers and restoration planners. Drivers of HABs include nutrient availability, temperature patterns, atmospheric conditions, rainfall-runoff relationships, and lake ...

Do fields with elevated soil test phosphorus disproportionately contribute to Western Lake Erie Basin dissolved phosphorus loading?

Agricultural &Environmental Letters, Volume 10, Issue 2, December 2025.
The relationship between soil test phosphorus (STP) concentrations and annual dissolved phosphorus (DRP) loads at the edge‐of‐field were upscaled to the Western Lake Erie Basin (WLEB). Results revealed that elevated STP fields disproportionately contribute to WLEB DRP loads but are not the dominant source leading to harmful and nuisance algal blooms ...

Development of Chitosan/PVA Nanofibrous Membranes for Efficient Removal of Microcystis aeruginosa

Journal of Applied Polymer Science, Volume 142, Issue 44, November 20, 2025.
Removal of Microcystis aeruginosa from CS/PVA fibers by A‐HSBS. ABSTRACT In this study, chitosan/poly(vinyl alcohol) (CS/PVA) polymeric nanofibers were produced using the Air‐Heated Solution Blow Spinning (A‐HSBS) method and applied for the efficient removal of Microcystis aeruginosa from contaminated water.

Biochar in Animal Agriculture: Enhancing Health, Efficiency and Environmental Sustainability

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
Biochar enhances animal agriculture by improving gut health (8%–26% higher feed efficiency), reducing methane emissions (up to 22%) and ammonia volatilization (40%–77%) and sequestering carbon. Challenges include variability in quality and economic feasibility, but its integration offers a sustainable path for productivity and environmental stewardship.
