01Depth & Water Temperature Suitability for Target Species

The depth of a fishing spot directly corresponds to the habitat depth of the target species. For example, cod are active at 30–80 m, whereas hairtail are active at 5–20 m.

Water temperature affects metabolic rate and prey activity; 15–22 °C is the range where most medium‑small fish actively hunt for food. Avoid areas where temperature changes abruptly.

Beginners should prioritize points with a depth of 3–12 m. This range is easy to handle equipment and allows you to see fish movement clearly.

02Current and Waves Determine Fishing Efficiency

Current creates fish migration pathways, and 0.5–2.0 kt (knots) is typical for a fishing point. When the current is too strong, bait moves unpredictably, reducing success rates.

Wave height of about 0.5–1.5 m is ideal. Higher waves disturb underwater prey particles, making it harder for fish to locate food.

On site, use real‑time current and wave data provided by the Korea Coast Guard; selecting sections where the current is ≤ 1 kt and waves are ≤ 1 m ensures stable fishing conditions.

03Accessibility·Parking·Facilities Review

Travel time to the site should be under 30 minutes before a trip. Long drives increase fatigue and diminish fishing focus.

Points with designated parking make transporting and storing gear easier. On public beaches, verify allowed parking zones in advance to reduce the risk of fines.

Proximity to restrooms, restaurants, and emergency facilities enhances safety by allowing quick response to urgent situations.

04Safety·Regulation·Environment Considerations

Since closed seasons and minimum size limits vary by province, check the latest notices on the Ministry of Oceans and Fisheries and the Fisheries Information Portal before heading out. For example, Gyeongsangnam-do enforces a closed season for certain species in May–June.

The Korea Coast Guard designates areas with rapidly changing tides, wind direction, or wave height as hazardous zones. These zones can be identified in advance via real‑time buoy data and marine forecasts from the Korea Meteorological Administration.

To protect the environment, prohibit littering and be sure to retrieve any remaining bait and line after fishing. This prevents water‑quality degradation and helps preserve fish habitats.

⚠ Common Mistakes
  1. Ignoring the current and fishing the same spot unconditionally significantly reduces fishing efficiency.
  2. If you don’t verify depth and temperature suitable for the site, bait may sink or rise abruptly, posing a risk.

05Matching Rigs & Gear to Site Conditions

Rigs vary with water depth. At 3–6 m, use PE #4‑6 line; at 7–12 m, use carbon #8‑12 line to optimize bait movement.

When water temperature is ≤ 18 °C, frozen bait (shrimp·squid) provides more consistent action than live bait, encouraging bites.

On site, position floating bait according to wind direction; controlling the drift direction of the bait increases bite probability.
