In a new essay, scientists point out that octopus should never be kept, not only because of their intelligence, but also because these farms will have an impact on the environment. The global demand for octopus food is on the rise. Due to the shortage of supply, the price soared last year. It is estimated that the price of octopus will remain high in 20 19 years. The production of octopus caught in the wild is unstable, which leads to unreliable supply, so all over the world began to try to cultivate octopus. Many countries in the world are making efforts to build octopus farms, including accelerating the transgenic experiment of cephalopod aquaculture. A team of environmental scientists, philosophers and psychiatrists wrote in the latest issue of Science and Technology magazine that artificial propagation of octopus will have some known environmental impacts, including nitrogen and phosphorus pollution caused by animal feces, hybridization and disease transmission, habitat loss and so on.

But the biggest environmental problem is the diet of octopus. Like most cultured aquatic organisms, they are carnivores and need fish protein and oil in their diet. Octopus larvae only eat fresh food. The researchers wrote: Raising octopus will bring additional fish meal pressure to wild fish and invertebrates. About one-third of the world's fishing is converted into feed for other animals, and about half of it is used for aquaculture. Many fishmeal industries are declining due to overfishing. Octopus needs a lot of food, at least three times its own weight. This kind of feed pressure may reduce human global food security. However, even if this problem can be solved, it is cruel to raise octopus in artificial farms. If you have been to the Ocean Aquarium, you may know this. Octopus is famous for its cleverness and problem-solving ability. Toys are usually put in octopus cans in case this cephalopod gets bored.

They can open cans, identify objects, remember problems they solved before, and even octopus can escape when the aquarium is full. So artificial breeding octopus is the prison of octopus. They also show worrying behaviors in artificial reproduction, including cannibalism and eating the tip of tentacles. Without stimulation, these animals will become depressed and bored. Scientists write that in addition to basic biological health and safety, octopus may need a high level of cognitive stimulation and opportunities to explore, manipulate and control the environment. Intensive farm system will inevitably conflict with these attributes.

Speaking of popular pets, Mr. Tang lamented the rapid change. A few years ago, snakes, chameleons and okumo were very popular. Nowadays, many people start to raise some highly toxic marine and tropical creatures, such as octopus and frog. Mr. Tang said that many people in different pet circles are chasing the trend and catching up with each other. Nowadays, popular pets are updated quickly, and the reason why crocodiles have fewer snakes is very simple, with less interaction, low attention and few words. It is very likely that next year, octopus will become new and there will be more weird pets. With the increasing popularity of different pets, whether it is illegal to domesticate different pets is a concern of many people. In this regard, it is understood that according to the relevant provisions of the Wildlife Protection Law, many privately raised snakes and lizards are wild animals, such as some giant lizards and crocodiles, which are national first-class protected animals. If artificial breeding is needed, it must be reported to the local forestry bureau, and the national protected animals must be reported to the provincial forestry department, and the breeding can only be carried out after approval. Otherwise, it is illegal.
