How to catch fish

Fishing method:

1. Bait fishing:

Fishing hooks are generally made of No. 18 steel wire. The length of the fishing hook is 4 cm, the width is 1.4 cm, and the hook tip is 1.3 cm long. The main line uses 210D/12×3 nylon strands, and the branch line uses 210D/8×3 nylon strands, which are 70 cm long. A branch line is connected to the main line every 2-3 meters, and each main line is connected to 15-20 branch lines. The bait depends on the fish: for fishing, it is best to use live loaches, striped fish, catfish, small red carp, etc. The hooks are hooked from the mouth of the live bait to the left and right, and the hook tip is exposed outside. The hook rope is placed while the fishing line is installed. After placing 2-3 hooks, a float is tied to the main line. The float rope is about 50 cm long, so that the bait can keep swimming in the upper layer of the water. After the hooks are released, straighten the main line and connect a large float at each end. Use a cotton thread with less tension to tie a stone under the float and sink it to the bottom of the reservoir. After the ferocious fish swallows the hook, let it struggle, and wait until it is exhausted before retrieving the hook and taking the fish.

2. Lure fishing:

Use 4-5 goose feathers (duck feathers or colored plastic sheets are also acceptable) as simulated bait for fishing. The hooks are made in the same way as before, except that each hook is tied with a lure. Usually, the operation is done at dawn or dusk. First, release the float and sinker at the beginning of the hook rope, and adjust the hook to about 0.5 meters from the water surface, and then release the hook. After the hook is released, connect the float to the end of the main line, and then release the rope. Use the boat to pull the rope in an "S" shape. At this time, feathers and other lures float in the water like small fish swimming, thereby attracting fierce fish. Once the fierce fish finds it, they will chase and grab the food, and end up being hooked.

3. Rolling hook fishing:

Rolling hooks are mainly used to catch mandarin fish. They take advantage of the habit of chub to enter the nest to spawn and are used to catch fish with empty hooks. The hooks are made of No. 16 steel wire, 7 cm high, 2 cm wide, and 2.5 cm long at the tip. They must be very sharp. The main line uses 210D/1 2×2 nylon strands, and the branch line uses 210D/8×3 nylon strands, 12-15 cm long. The distance between the two branch lines is 10-15 cm. A float is tied to every 30-40 hooks on the main line. Before placing the rolling hook, multiple horizontal trenches with a width of 40-60 cm, a depth of 10-15 cm, and a length determined by the terrain must be dug in the spawning ground of chub in the upper reaches of the reservoir with a water depth of 0.6-1.2 meters. Rolling hooks are generally used to catch chub at night from April to June. When placing the hook, adjust the rolling hook to a suitable position 4-5 cm from the bottom of the water. The rolling hook keeps rolling in the ditch under the action of the water flow. When the h fish swims upstream to the spawning ground and enters the ditch, the fish body will be hooked by the sharp tip of the rolling hook. The more it struggles, the more the rolling hook will hook and the deeper it will hook. When the fish is exhausted, the hook will be reeled in to take the fish.

How to keep fish in a fish tank

Ducks cannot be kept in fish tanks and are usually kept in ponds.

The pond area can be between 2 and 10 mu, the water depth can be between 1.5 and 2 meters, the pond bank must be solid and leak-proof, drainage and irrigation are convenient, and the thickness of the silt at the bottom of the pond should not exceed 20 centimeters.

Fish farming is the main method. In order to regulate water quality, a small amount of silver carp and bighead carp can be raised per mu. The stocking density depends on the pond conditions and management level. Generally, 800 summer flower fish of about 3 cm in size and about 50 one-year-old silver carp and bighead carp of 50g per mu can be raised.

The difference between wild and domestic fish

The fish is a ferocious large fish that swims very fast and is not suitable for domestic breeding. Generally, only fry can be raised. The difference is that domestic fish are relatively docile than wild ones and the frequency of hitting and jumping into the tank is lower.
