01Lure and live bait, basic concepts and differences
A lure is an artificial bait made from synthetic materials such as metal or plastic, stimulating visual cues and vibrations through its movement in the water. In contrast, live bait uses natural ingredients like actual fish or crustaceans to convey scent and subtle motion.
Lures can be freely adjusted in color, shape, and weight, allowing optimization for various species and depths. Live bait, rich in fish oil, slowly dissolves in the water, continuously releasing a natural scent.
Both methods trigger the predatory instincts of fish, but lures focus on visual and vibrational cues while live bait relies on chemical and tactile cues. Understanding this fundamental difference makes it easier to choose the right option for each situation.
02Optimal rig selection by depth and temperature
According to data from the National Institute of Fisheries Science (NIFS), cold‑water species (such as scallops, cod, etc.) become active when water temperature is 15 °C or below. In these conditions, scent‑rich live bait is most effective.
Conversely, when water temperature exceeds 20 °C, warm‑water species (such as Korean rockfish, sea bass, etc.) are primarily caught. The high‑speed spin and flashing colors of a lure attract these species.
In the 10 m–30 m depth range, live bait naturally rises with water flow, while in the 30 m–80 m range, a lure can maintain precise depth through weight adjustment.
03Timing and tips for using lures and live bait
During the golden time—approximately two hours before and after sunset—fish activity spikes as they search for food. The lure’s flash becomes more noticeable, prompting bites.
On overcast days or when wave action is weak, chemical cues in the water become more important. The scent released as live bait dissolves draws fish in.
When using a lure, set the spin rate (RPM) to 1500–3000 and adjust the retrieve interval to 1–2 seconds. For live bait, set the rod sensitivity to level 3 (medium) and minimize movement in the water.
04Cautions and common mistakes
Excessive lure spin creates water noise that can startle fish, causing them to flee. Especially when water temperature is 18 °C or below, keep spin speed under 2000 RPM.
The longer live bait remains in the water, the more it decomposes, and the resulting scent can have a negative effect. If left in water for more than two hours, discontinue use and replace with fresh bait.
If both sides ignore the fish’s habitat, fishing efficiency drops sharply. Research local and seasonal fish activity patterns in advance and select appropriate gear and bait—that is the key.
- Excessive lure spin speed: increased water noise
- Choosing a lure that is too light makes depth maintenance difficult
- Storing live bait too long leads to decay and adverse scent
- Use lures and live bait together to stimulate multiple fish senses
- Adjust bait weight and length to match depth and temperature
- Apply spin‑pause patterns timed to golden time
