The eight-armed sea animal known as the octopus(章鱼) is becoming a popular food in many parts of the world. But, as more people want to eat them, the population in the wild is decreasing. Experts blame rising ocean water temperatures and overfishing for their falling numbers.

Octopuses do poorly in warm water. And since they are in great demand, fishermen can make more money by catching them in the wild. As a result, a small fishing village in southern Mexico is working with one of the country’s universities. The group wants to find out if the sea animals can be farmed successfully.

Carlos Rosas, a biologist, is working to start an octopus farm in the fishing village of Sisal. Recently, Rosas showed reporters the farm. He reached into a large tank and pulled out a baby octopus, about the size of a small ball. The octopus lives in the tank with about 250 others. The project aims to see if the babies can live to be large enough inside the tank to be sold for food.

Scientists and animal welfare activists have long been concerned about growing octopuses inside tanks. The animals are believed to be able to think and also to feel happiness and worry.

Now, Rosas and his team think they may be able to keep the octopuses healthy until they are large enough to sell. They have created a food for octopuses from fish waste, like heads, which are normally thrown back into the ocean by fishermen. The food is turned into small balls which are fed to the octopuses. Rosas said the farm gets what it needs for the octopuses and the fishermen can make extra money by selling their unused fish parts. He said the plan is to make the fishing business more “efficient” and raise the number of octopuses available for food.

If the project is successful, its timing will be just right. One research company predicts that by 2025, the worldwide demand for octopuses will increase by over 60 percent from 2018.
