Answer

To determine the source of fish glue, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fish Glue**: Fish glue is a type of adhesive that is proteinaceous and water-soluble. It is derived from various parts of fish.

2. **Identifying Fish Parts**: The main components from which fish glue is made include keratin, elastin, and collagen. These proteins are found in specific parts of the fish.

3. **Boiling Process**: The bones and skin of fish are boiled. This process extracts the proteins that act as agglutinating agents, which are essential for creating the glue.

4. **Cooling and Drying**: After boiling, the extracted substances are cooled and dried. This results in a gelatinous form of adhesive known as fish glue.

5. **Conclusion**: Based on the information, fish glue is specifically obtained from the bones and skin of fish. Other options like air bladder and scales do not contribute to fish glue production.

### Final Answer:
Fish glue is obtained from **bones and skin** of fish.
