Complete with plants, herbivorous creatures, carnivorous creatures, and microorganisms constituting a cycle.
If experimental materials are lacking, resupplies should be arranged promptly.
In any case, the principle is to construct a complete, cyclical, miniature underwater ecosystem.
Any other method of destruction, such as poison, witchcraft, simulating earthquakes, should be avoided.
The method that Link proposed to eliminate gigantic carnivores was quite common.
It's simply a gradual increase in temperature.
This idea comes from a speculation about the reason for the extinction of a certain species of dinosaur in his previous life.
Link wanted to see if constantly raising the temperature to a certain degree would disrupt the mini ecosystem.
For example, the "natural" death of the ferocious fish representing the massive carnivores.
When one whale falls, all creatures propagate.
The death of a gigantic ferocious fish would undoubtedly affect the miniature ecosystem.
