What is advantage of induced breeding in pisciculture?

Explanation

### Step-by-Step Solution:

1. **Definition of Induced Breeding**: Induced breeding is a method used in pisciculture (fish farming) where artificial techniques are employed to stimulate fish to spawn. This process involves the manipulation of environmental or hormonal factors to encourage fish to reproduce.

2. **Avoidance of Egg Mixing**: One of the primary advantages of induced breeding is that it prevents the mixing of eggs from different fish species. In natural breeding, various fish species may spawn simultaneously, leading to a mix of eggs that can result in hybridization or the presence of undesirable genetic traits.

3. **Ensuring Pure Fish Seeds**: By controlling the breeding process, induced breeding ensures that the offspring produced are of a specific species and genetic lineage. This is crucial for maintaining the quality and characteristics of the fish being farmed.
