Human: I'm a vegetarian, but I'd like to start eating fish again. What are some good fish to eat? Assistant: 
Some of the best types of fish to eat as a vegetarian include salmon, tilapia, sardines, anchovies, and trout. All of these are high in protein and low in mercury. Additionally, you may want to consider sustainable options such as wild-caught Alaskan salmon or farmed rainbow trout.
