Orange roughy can live to be 130 years old. They start to breed when they're 25–30 years old.Determine whether they are a renewable or non-renewable resource.

To determine whether Orange roughy is a renewable or non-renewable resource, we need to understand the definitions of these terms.

1. Renewable resources are those that are replenished naturally and over relatively short periods of time. This includes resources like solar energy, wind energy, and even certain types of fish or forest products - if they are harvested sustainably.

2. Non-renewable resources, on the other hand, are those that either do not replenish at all or do so over very long geological periods. This includes resources like fossil fuels and minerals.

Now, let's apply these definitions to Orange roughy:

Orange roughy are fish that have a very long lifespan (up to 130 years) and a late age of maturity (25-30 years). This means that it takes a long time for them to reproduce and replace their numbers. If they are fished faster than they can reproduce, their population could decline or even collapse, making them effectively non-renewable.

However, if fishing of Orange roughy is carefully managed to ensure that the fish are not being caught faster than they can reproduce, then they could be considered a renewable resource.

So, the classification of Orange roughy as renewable or non-renewable is not fixed, but depends on how they are managed. Overfishing can make them effectively non-renewable, while sustainable fishing practices can help maintain them as a renewable resource.
