The catch rating of an ingredient is generally an average, meaning the average rating of a species. There are differences between individual species, for example, the average capture level of the Gala crocodile is 5, but the 300 year old Kala crocodile that Aru encountered had a capture level of 8. Even though it is the same species, the capture level increases as it gets older. Therefore, it is possible to increase the combat strength and capture level by practicing and exercising, but it should be within a certain range. Take a level 23 species for example, the individual members of it should have a capture level of almost between 13 and 33. If it's been working out long enough to become the king of its species to gain a capture level of 30 or higher he can beat a level 30, or even a level 33. But it will never be able to defeat a level 34+, no matter how much it exercises, because its limitation is level 33. Just like a tough cat can beat a weak dog, but no matter how tough it is exercised it can't beat a tiger. It's a difference between the species that can't be solved through exercise. But it can be solved through evolution, which is when a cat evolves into another species that can defeat a tiger, but then it's not called a cat anymore. It's the same in the world of food captives, you understand ~~~~~~~~
