How effective is the excavator in digging fish?

Excavator, as a kind of heavy engineering machinery, is mainly used for excavating, loading and transporting various materials. In recent years, with the wide range of its applications, excavators have also been tried to be used in some non-traditional fields, such as digging fish. However, what is the effect and impact of this usage?

Capture efficiency: From a pure efficiency perspective, digging fish with an excavator does have its advantages. Its powerful digging capacity and operating range allow it to cover large areas of water in a short period of time, making it possible to catch a large number of fish. However, this improvement in efficiency is also accompanied by a series of problems.

Fish damage: When the excavator digs out fish, it is easy to cause damage to the fish due to the rough working method. This damage not only affects the survival of fish, but may also have long-term effects on fish reproduction and ecological balance.

Selectivity problem: It is difficult to selectively fish when digging fish with a digger. This means that while target fish are being caught, other non-target fish may also be accidentally caught, including some rare or protected species. This indiscriminate fishing method undoubtedly poses a threat to aquatic biodiversity.

In summary, although digging fish with an excavator has shown certain effects in some aspects, its negative impacts cannot be ignored. Therefore, we do not recommend using the digger as a regular fishing tool. On the contrary, we should advocate more sustainable and environmentally friendly fishery development methods, such as developing ecological fisheries and promoting selective fishing techniques. At the same time, the government and relevant departments should also strengthen the supervision and protection of fishery resources to ensure the sustainable use of fishery resources.

Finally, it needs to be emphasized that the development and application of any technology should be based on protecting the ecological environment and respecting life. Only in this way can we achieve harmonious coexistence between man and nature.
