Synergistic Pairing with SFA 400
For optimal results, Marukyu recommends pairing Gure Ni Koreda (SFA 450 - liquid) with SFA 400 (krill powder):
-
In groundbait: use SFA 400 powder for the base (10-15% of the mix)
-
On baits: treat with SFA 450 liquid for an immediate boost
-
Combined effect: both immediate (liquid) and gradual (powder) release
-
Complete scent trail: total coverage of the fishing area
What "Gure Ni Koreda" Means
The Japanese name "Gure Ni Koreda" translates to "This is for Salpa Salpa," indicating its specific vocation for this marine species highly prized in Japan. Sarpa salpa (Gure) are extremely selective fish that feed mainly on krill, making this additive particularly effective. However, its effectiveness extends to all marine and many freshwater species.

💡 Expert Tip
For gilthead seabream fishing, create a "super bait" by soaking Korean worms in a diluted Gure Ni Koreda solution (10ml in 50ml of water) for 15-20 minutes before the session. Simultaneously, enrich your sardine groundbait with 30ml of pure concentrate per kg. This two-level approach creates an irresistible scent trail that guides seabream directly to your bait, drastically increasing catches even in difficult conditions.
