Cannabidiol and microbubble aeration enhance stress resilience and physiological homeostasis in European sea bass: a multi-tissue integrative approach
Addressing growing concerns about animal welfare in aquaculture, this study investigates the potential of cannabidiol (CBD) and microbubble aeration to enhance stress resilience and physiological homeostasis in European sea bass. A five-week trial assessed the effects of dietary CBD (0.001%), environmental enrichment through modified aeration, or their combination on key welfare indicators.
Does anyone know a cheap way for students in middle school to test for dissolved oxygen levels in water?
Middle school students exploring nutrient pollution’s impact on ocean health can effectively model phytoplankton blooms and subsequent oxygen depletion. A key challenge, however, lies in accessible dissolved oxygen (DO) measurement. While sophisticated equipment exists, cost-prohibitive barriers often limit public school access. Researchers are actively exploring innovative solutions to monitor crucial climate indicators like DO, as highlighted in our article, "Sharks Equipped With Sensors Could Help Predict Hurricane Intensity." We invite educators to share their strategies for affordable, reliable DO testing in classroom settings.
Combined effects of climate and anthropogenic change on habitat suitability and distribution of threatened marine species in China’s coastal waters
Understanding the combined impact of climate change and human activities on threatened marine species is paramount for effective conservation. A recent study utilizing an ensemble species distribution modeling framework projects substantial shifts and contractions in habitat suitability for ten threatened species in China’s coastal waters. Integrating factors like fishing pressure and coastal pollution alongside climate variables revealed a 40% reduction in suitable habitat under global-change scenarios.
Data-driven modelling of coastal water quality dynamics
Long-term coastal monitoring offers a unique opportunity to assess water quality predictability, yet existing machine learning studies often lack comprehensive scope. Our analysis of 37 years of data from 94 stations across four Hong Kong Bay systems reveals significant regional variations in predictability and key predictors. Tree-based models demonstrated robust performance, particularly for temperature and salinity, while chlorophyll-a proved consistently challenging to forecast.
