Why are fish populations in the Gulf of Maine in a state of flux? It’s the very composition of the oceans, say researchers. The warning bells have sounded for years: Ocean warming is affecting the distribution, growth and reproduction cycles of fish, shellfish and other marine life around the world. The very composition of our oceans is changing, climate researchers say, bringing challenges for seafood harvesters, scientists and regulators alike.

ELIFE® mejoró el crecimiento, la supervivencia y las defensas antioxidantes de juveniles de P. vannameiEl estrés oxidativo puede resultar del desequilibrio entre los niveles de agentes prooxidantes y el sistema de defensa antioxidante del camarón. Durante el proceso, también se produce la formación de subcomponentes nocivos para los animales. Las especies reactivas de oxígeno (ROS) son moléculas capaces de oxidar y dañar biomoléculas como lípidos, proteínas y ácidos nucleicos.

The impacts of extreme events on fisheries biomass, harvest, economic performance are yet to be examined as a systemMarine ecosystems and their living marine resources (LMRs) continue to respond to the effects of global change, with environmental factors affecting these coupled social-ecological systems. Extreme events such as high category hurricanes, harmful algal blooms, marine heatwaves, large-scale hypoxia and anthropogenic events such as oil and chemical spills affect marine ecosystems.

Results of this study show that mysid meal could be a viable alternative and stimulate shrimp growth at 65.50 percent replacement levelsZooplankton has been proposed as a sustainable source of feed ingredients for aquaculture since its nutritional compositions are reported to be comparable to fishmeal. The global productivity of zooplankton biomass typically produces hundreds of millions of tons, and their reproductive turnover rate is fast.
