Expanding recirculating aquaculture systems, improving seed quality are crucial for domestic trout to challenge the salmon market. The Korea Institute of Ocean Science & Technology (KIOST) recently analyzed in its report 'Preliminary Tasks for Domestic Trout Challenging the Salmon Market' that the trout industry is expanding its growth base through increasing production of large fish, advancing processing and distribution, and attracting younger generations. However, reliance on flow-through aquaculture systems, seed quality instability, and groundwater resource constraints were identified as issues that still need to be resolved. The report summarizes the contents as follows: The trout industry is improving its structure to target the salmon market.
