Scatter net fishing is a type of commercial fishing technique used to catch large amounts of fish quickly. This type of fishing involves setting a large, wide net that is then drifted with the currents and scattered with bait. The bait attracts fish, which are then scooped up by the net.

Scatter net fishing is an ancient and effective fishing method that generally requires the following steps:

1. Choose a suitable location

Generally, choose a freshwater area with a slow current or a shallow water area near the coastline for fishing.

2. Choose the right net:

According to the fishing site and the size of the target species, choose the right net, generally divided into two kinds of triangular nets and round nets.

3. Preparation for spreading the net

Lay the net flat, fix the edge on the ground, and then use a heavy object in the center of the net to hold it down so that it will not float.

4. Spreading the net

Scatter the net slowly from the boat or the shore, while slapping the water with your hand or bamboo pole to drive the fish to swim to the center of the net.

5. Collect the net

When the fish swim to the center of the net, quickly retrieve the net and trap the fish in the net, then tie the net with a rope and bring the fish back to the shore or the boat.

It should be noted that in the process of spreading the net to catch fish, it is important to avoid catching non-target species or causing adverse effects on the marine environment.

You need to understand the local laws and regulations, and policies related to the protection of the ecological environment.

Cast net fishing has its advantages and disadvantages.

Advantages:

1. Low cost

Compared with other fishing methods, scatter net fishing is less expensive and does not require much equipment or investment.

2. Environmentally friendly

Scatter net fishing does not use a lot of chemicals and does not pollute the water or damage the ecosystem.

3. Efficient

In suitable waters and conditions, scatter net fishing can catch a large number of fish.

Disadvantages:

1. Limited fishing effect

The effect of net fishing is affected by various factors such as weather, geography, and environment, and is not as stable as other fishing methods.

2. Single-catching object

Since netting depends on the swimming of fish, it can only catch the fish swimming in the net, which is not suitable for some fish species that do not like to swim.

3. Limited catching capacity

The catching capacity of scatter net fishing is limited by the size of the net and the number of fish, so the catching capacity is not as much as other high-tech fishing methods.

In summary, although scatter net fishing has advantages and disadvantages, it has unique advantages in protecting the environment and saving costs.
