A Step Toward Sustainable Salmon Farming Through Feed-Based Sea Lice Control.

A new feed-based method for controlling sea lice, a long-standing challenge in Atlantic salmon farming, has been developed. The annual cost of dealing with sea lice exceeds 4 billion yen, and resistance to conventional treatments has been increasing, making the issue even more pressing. In response, a novel approach using feed additives has been introduced to combat sea lice. This method not only targets sea lice but also helps reduce disease outbreaks and mortality rates, contributing to more sustainable aquaculture.

The feed-based solution offers several advantages: it does not interfere with feeding or growth, can be easily integrated into existing farming operations, and helps reduce fish stress. Furthermore, it minimizes the need for physical interventions, leading to savings in labor and equipment costs. These improvements are expected to enhance the quality of harvested fish and may positively impact the market value of farmed salmon.

Since sea lice pose a serious threat not only to Atlantic salmon but also to wild salmonid species, effective and sustainable solutions have been in high demand. This feed-based approach represents a significant step forward in reducing the environmental and biological burden of fish farming, and it is expected to drive future growth and innovation in the salmon industry.
