1. Selection of anchor hook:
First of all, the choice of the anchor hook on the fishing tackle is fixed, and the size of the anchor hook should be selected to be able to bear more than ten kilograms of fish, because the anchored fish are generally large, and the fishing rod should be particularly hard, and the fishing line should be at least 2.0 thick, otherwise it is easy to break the line. The main line and the auxiliary line must be separated here, because the underwater situation is complicated and it is easy to hang on obstacles.
2. Choice of fishing location:
The fishing tackle is ready, so it's time to choose the fishing position. For anchor fish, the fishing position should be selected in the deep water area, and there should be few obstacles at the bottom of the water, so that the clear bottom will not be hooked.
3. Dorian:
Although many fishermen think that anchor fish don't have to make nests, fishing and boating don't have to make nests, other nesting methods can improve the catch rate of catfish. If you adjust your position and sprinkle a little nest material along your fishing line, you can attract fish well. This method of anchoring fish is not fixed, but it can be put away at night and in the morning without wasting time.
4. Slippery fish:
Anchor fish must walk, especially when the scales are thick. When walking the fish, you must keep the strength of the fishing line and don't relax at all. This kind of fish is very strong in water. If you pull hard, it will cause the fish to decouple, so you must master the skills of walking the fish.
Principle and application of anchor fish;
First, the principle:
1, principle of force balance:
The principle of anchoring fish is based on the principle of force balance of objects. When the ship is docked, the anchor fish puts the weight into the water and connects with the ship to form a balanced state of force. This force balance can effectively prevent the ship from drifting in the water and maintain the stability of the ship.
2. Hydrodynamic principle:
The principle of anchoring fish also involves the knowledge of fluid dynamics. The influence of current on anchor fish is transmitted to anchor fish through the force of current on anchor chain or cable. The strength of the current can make the anchor fish firmly fixed at the bottom of the water and increase the anti-drift ability of the anchor fish. At the same time, the direction and speed of water flow will also affect the stress of anchor fish, so we should choose the appropriate anchor fish form and release position according to the actual situation.
Second, the application:
1, ship stops:
Anchoring fish is an important equipment when ships dock. By anchoring the fish, the ship keeps a stable position in the water, which is not affected by current and wind, and ensures the safe docking of the ship.
2, coastal engineering:
In coastal engineering, anchor fish is used to fix floating equipment and structures, such as pontoons and floating docks. Anchor fish can keep the stability and safety of equipment and structure by resisting the impact of current and waves.
3. Underwater exploration:
In underwater exploration, anchor fish is used to fix measuring equipment and detectors. By fixing the equipment, the anchor fish ensures the stable position and posture of the equipment underwater, and improves the accuracy and reliability of measurement and detection.
