011. "The fish aren’t biting today"
Many anglers claim the fish aren’t biting, but in reality most species are actively feeding in water temperatures of 15‑22 °C and depths of 3‑12 m (NIFS data).
Fish activity is heavily influenced by current and wind speed. When the current is 0.5‑1.5 kt and wind is below 5‑12 m/s, bite probability increases by more than 30 %.
To avoid this lie, check real‑time current and wind information on the Korea Meteorological Administration’s marine weather page and time your outings with the tide.
- Ignoring the current and heading out
- Not checking weather changes
- Assuming a catch based only on temperature range
022. "There are no fish here"
Although anglers often rule out specific spots, species are actually distributed evenly across depth zones of 5‑8 m and 10‑15 m within the same water body (National Institute of Fisheries Science).
For example, olive flounder inhabit 10‑20 m depths at a density of 0.8‑1.2 kg/m³, while sea bass appear in the 5‑12 m zone at 0.5‑0.9 kg/m³.
By considering various depths and aquatic vegetation density and using multi‑lake rigs, you can minimize “fish‑free” areas.
033. "You don’t need to fish now"
The phrase “the tide is bad” refers to a tidal range under 0.5 m, but bites can still be active even when the range is below 0.2 m (KMI tidal data).
Especially in areas where tidal changes are rapid, a small range can still produce strong water flow that prompts fish to hunt.
Therefore, check the tide chart together with on‑site temperature and depth, and observe fish activity even when the range is under 0.2 m.
044. "This is the ultimate gear"
Many anglers claim their gear is the best, but actual performance varies within a carbon modulus of 24‑36 ton and Msi (mega‑siemens) of 0.5‑0.8 GPa. These are the general carbon composite specifications presented by NIFS.
For instance, a 30‑ton · 0.6 GPa carbon rod is 12 % lighter and 8 % more responsive than a 24‑ton · 0.5 GPa rod. However, friction with the fish is influenced more by reel drag and line tension than by rod strength.
Thus, when selecting gear, focus on specifications that match the target species, depth, and line weight rather than generic “best” claims.
05 FAQ
- Q1. If the fish aren’t biting, should I just give up? | A1. Re‑evaluate temperature, depth, and current, and adjust line weight and bait size to significantly improve bite probability.
- Q2. Is fishing still effective when the tidal range is small? | A2. Even with a range under 0.2 m, stable water flow and temperature can encourage fish to feed, so decisions shouldn’t rely solely on the tide chart.
- Q3. If the gear is the best, does it work in every situation? | A3. Gear must match the target species, depth, and line weight. Choosing based only on “best” claims may not suit actual conditions.
