How Real-Time Monitoring Tansforms Feed Efficiency in Precision Aquaculture
Precision aquaculture, powered by real-time monitoring systems, is revolutionizing how fish farmers approach feed management In today’s competitive aquaculture landscape, feed represents the single highest expense in raising fish, often accounting for 60 to 70 percent of total production costs. As global seafood demand continues to surge and operational expenses rise, maximizing feed efficiency has become critical for maintaining profitable operations.

Water quality impacts on health and performance of fish and shrimp, Part 2: pH, carbon dioxide, alkalinity, hardness and the water buffering system
Although there is a general consensus on the importance of water quality, many farmers still underestimate the negative impacts of marginal water conditions on aquaculture outcomes This second of two parts addresses the relationships among pH, carbon dioxide, alkalinity, and hardness, and the effect of these parameters on performance and health of farmed fish and shrimp. Hardness and alkalinity are the main components of the water buffering system (WBS).
