Do trawling fish have any disadvantages?

Fish caught with trawls can have several disadvantages. Firstly, this method can be unethical because trawls can kill not only fish but also other marine life such as dolphins and whales. Secondly, trawls can be very effective in catching fish, which can lead to fish population overload and ecosystem degradation. Thirdly, this method can be harmful to the fish as it can cause injury and pain.

Yes of course. Fish are at risk of being damaged by this fishing method.

Oczywiście że tak ponieważ sieć włokowa uszkadza ciało ryby, pęta je a ryba umiera co doprowadza do wymierania gatunków oraz zanieczyszczenia wód

It should also be remembered that this way of obtaining fish is illegal in Polish water and PZW (Polish Angling Association) and on private fisheries

And so collecting the whole thing is not profitable for financial and moral reasons

Yes, trawling fish has several disadvantages. The most painful thing is that this method causes poisoning of the environment with toxic waste, which is left on the bottom with the remains of fish baits or the trawls themselves. Another disadvantage is that this method can also contaminate other bodies of water and cover long distances, which sometimes means juveniles or species that are not allowed to be caught are caught. This method can often mean overfishing, which harms local populations. Sometimes trawls attract smaller fish as well as predators that can deprive them of their natural habitat. It can be said that trawl food waste is a threat to the ecosystem and may be a side effect of the method of catching fish with these gears. In addition, it is difficult to control the depth of fishing. In addition, it requires a lot of effort, which can be especially troublesome when fishing for long periods. In addition, strings and lines exposed to pressure wear out quite quickly, so it is necessary to replace them often. Finally, this method prevents precise and selective catching of certain species of fish.

Fish can suffer or die when fishing with trawls. Trawls left behind are dangerous for fish, which can get stuck in them and lose their lives. It is therefore important that all trawls are returned to the drawer when fishing is complete and that they are checked regularly for injured or dead fish.

Fish caught with trawls, like any fishing method, has its advantages and disadvantages. One of the disadvantages is that they can cause a lot of unnecessary trampling of fish that happen to be accidentally caught on the line but are immature, undesirable or threatened with extinction. In addition, the exploitation of trawl fisheries can affect fish stocks, which may lead to a shortage of fish in the long term.
