Phytoplankton are microorganisms that influence the entire aquatic food chain. Due to photosynthesis, they are also a huge consumer of carbon dioxide (CO2), and are the main oxygen producers in most aquatic environments. The right balance of phytoplankton is extremely beneficial and necessary for fish health; however,

When it comes to fish feed, the ingredients have traditionally included fishmeal and fish oil. With new technology and environmental concerns, restrictions on the use of fishmeal and fish oil are being implemented and new research is discovering alternative ingredients for more sustainable sources of nutrients to

As spring approaches, it is important to be prepared for springtime diseases and dissolved oxygen loss on your aqua farm. Abrupt temperature changes, decreased oxygen levels, and bacteria are all factors leading to springtime fish deaths, but they can mostly be prevented or alleviated. Why Are My

When talking about climate change, you often hear “higher temperatures mean less fish” or similar. But how does temperature actually affect fish health, growth, and livelihood? Temperature levels affect the metabolism, respiration, reproduction, and the susceptibility to toxic compounds of fish. Metabolism Rates vs. Temperature An increase

Declining fish health continues to illustrate the repercussions of climate change. Heightened temperatures and drought do more than merely reduce the water available for fish habitat; they increase water’s carbon dioxide and acidification. Real-time water monitoring is critical to the future of fish species stressed by climate

Fish breathe oxygen just as we do, so dissolved oxygen (DO) is a critical environmental indicator in aquaculture. Depleted DO is the leading cause of fish kills, and fish farmers know that low-oxygen conditions are their worst enemy. Low DO saturation can be caused by a host
