Hello friends of the farm in this opportunity I am going to speak to you about the harmful thing that is the electrical fishing for the marine spice and our environment and that in spite of this there are governments that sponsor them.

WHAT IS ELECTRICAL FISHING?

Electric fishing is a modification of traditional trawling. Trawling consists, as its name suggests, in dragging a net through the sea capturing everything that is in its path. Placing a few balls of lead in the lower part of the mouth of the net and a bollas in the upper one it is possible to keep the net open during the whole drag.
Electric fishing and its controversy within the fishing sector. The defenders of this technique, who have launched an important communication offensive, defend their value as a weapon against climate change.
His critics assure that it is equivalent to "hiding" the last fishing resources, already harassed by industrial fishing.


SOURCE

Electric fishing was considered an "innovative technique".
Currently 10% of the Dutch fishing fleet is authorized to use this technique. A dozen British ships also use it.
It is estimated that almost an electric fishing technique flourished in the East China Sea, where in the early 1980s the overfishing of prawns had dramatically reduced catches. The trawl nets were modified to cause electric shocks that crushed the crustaceans and made them "jump" from the seabed, allowing an easy capture.
One of the characteristics that defines us human beings is the ability to invent machines and techniques that make life easier, if possible, obtaining the maximum benefit with the minimum of effort. But what we often forget is the subject of ethics and common sense, and an example of this is electric fishing.


SOURCE

The fishing fleet has been forbidden for almost two decades, the use of destructive fishing gear such as the use of poisons, explosives, pneumatic hammers and electric currents. However, there is a small exception: in the North Sea it is allowed to obtain 5% of the annual quota using "innovative methods" that serve for research, among which is electric fishing. But here we are in the same dynamic as the tricky subject of whaling and the famous Japanese excuse that they fish "for scientific purposes."


SOURCE

THE TRAILER FISHING HAS THREE MODALITIES:
Background (drag on the background),
Pelagic (drag in the water column)
Semipelagic (the mouth of the net is larger to cover both the bottom and part of the water column).
Electric fishing is considered a variant of bottom trawling. The lower part of the network carries a series of electrodes that release electrical currents to the sea floor, causing the fish that live in it, such as flounders, to convulse or become stunned, or even paralyzed, which causes them to rise from the sea. background, thus facilitating its capture.

ELECTRICITY FISHING HOW IT WORKS
It consists in adding electrodes to the networks. The small electric shocks "lift" the fish that take refuge on the seabed, such as sole, turbot and some crustaceans, allowing them to be captured.
It works like traditional trawling, but using electrodes instead of the chains that are used in traditional trawling to "scratch" the seabed, the so-called "gates".


SOURCE

ARGUMENTS IN FAVOR
The fishing lobbies in favor of the implementation of this technique ensure that it is less aggressive to the seabed than traditional trawling.
They also point out that it is better for the environment because it saves fuel (they fill their networks more quickly which reduces consumption) according to the fleet that has received the authorization.
Another argument of the industry is that unwanted catches are reduced. 50% less unwanted specimens are captured.
-Fish between 4 and 5 times more than with the other techniques.
-It has been used since the 1950s in continental waters for scientific purposes because it is not very invasive.
-It allows access to resources that were more difficult to reach until now, such as flatfish that live half-buried, because with the normal trawl some have the possibility of escaping.
-The discards are returned to the sea in better condition than those caught by traditional trawling.


SOURCE

COUNTER ARGUMENTS
Such is the scarcity of electric fishing that, in addition to a multitude of ecological and scientific associations, fishermen who use this technique are also opposed completely.
According to some environmental groups, this fishing is worse than traditional trawling because the discharges affect all species, animals and plants, of the seabed. In addition, fish with damage to the spine and others with ulcers caused by the electrodes would have been found.
Electric fishing is called "destructive", understanding as such the one that made use of "explosives, poisons, soporific substances, electric current, pneumatic hammers or other percussion instruments
The platform of artisanal fishermen has compiled testimonies of fishermen on the state of the marine environment after the passage of the electric networks and summarize everything in a word: desert
-Fish fishing, by itself, is a very non-selective art. That is to say, between 50 and 60% of the captured species are not desired.
-The powers that are used in the sea for electric fishing are much greater than that applied to capture a fish for scientific purposes in fresh water.
-The electrocution causes fractures of the spine, bruises and burns, so discards are returned to the sea in worse condition than those of trawling.


SOURCE

-The powers that are used in the sea for electric fishing are much greater than that applied to capture a fish for scientific purposes in fresh water.
-The electric current not only affects the fish, but also all the invertebrates that are in the way of this, and these are the basic food for many species, so the impact could go far beyond the species captured.
-The electric fishing harms the traditional fishermen because due to their extraordinary effectiveness the traditional fishermen have nothing left to fish. In short, it is unfair competition.

THERE'S LAW MADE THE TRAP
Supposedly there are scientific studies that corroborate that approving electric fishing with limitations would not lead to a negative and direct impact on the marine environment.


SOURCE

International organizations have indicated that, although electric fishing is potentially less destructive than trawling, there are insufficiently researched elements that prevent its endorsement to practice.

WHAT SCIENCE SAYS
This has been dedicated economically to take advantage of the authorization for electric fishing instead of investigating. International organizations have indicated that, although electric fishing is potentially less destructive than trawling, there are insufficiently researched elements that prevent its endorsement to practice. Another argument is that the fish are supposedly returned in better condition, although the injuries caused by the electrical contraction in cod were proven: they were able to split the backbone. On the other hand, studies have focused on fishing species, not on ecosystems.
In short, the supporters hide behind the fact that there are no studies that oppose the use of electric fishing, but the problem is that there have been no in-depth scientific studies on this subject, so there is not enough information to accept or reject the technique based on scientific arguments.
