Which harmones are administrered in aquaculture technique to obtain seed fish in pure form

Options

A. Pituitary hormones
B. Sense hormones
C. Thyroid hormones
D. Parathryroid hormones

Answer

### Step-by-Step Solution:

1. **Understanding Aquaculture**: Aquaculture is the farming of aquatic organisms, including fish, crustaceans, mollusks, and aquatic plants. One of the key processes in aquaculture is the breeding of fish to ensure a good yield.

2. **Induced Breeding Process**: In aquaculture, the induced breeding technique is commonly used to stimulate fish to spawn. This is often necessary to obtain seed fish in pure form.

3. **Role of Hormones**: Hormones play a crucial role in the induced breeding process. Specifically, hormones from the pituitary gland are administered to the fish to trigger reproduction.

4. **Identifying the Key Hormones**: The primary hormones used in this process are:
- **Follicle Stimulating Hormone (FSH)**: This hormone helps in the maturation of the eggs in female fish.
- **Luteinizing Hormone (LH)**: This hormone is responsible for triggering ovulation in female fish.

5. **Administration of Hormones**: The hormones are typically injected into the fish to induce spawning. This method is widely accepted and is an economical way to ensure the breeding of fish.

6. **Conclusion**: Therefore, the hormones administered in aquaculture techniques to obtain seed fish in pure form are **pituitary hormones**, specifically **FSH and LH**.

### Final Answer:
The hormones administered in aquaculture to obtain seed fish in pure form are **pituitary hormones**, specifically **Follicle Stimulating Hormone (FSH)** and **Luteinizing Hormone (LH)**.
