魚肉 Vs 豬肉

I think both meat are rich in protein. However, the pork meat may have more saturated fat than fish meat. It makes fish meat is more healthy than the pork meat. However, both of the meat contains very low level or even no Vitamin B12 which is only present in red meat.
You can start to be vegetarian after the puberty. However, you have to make sure that you absorb eough protein and calcium for your growth. Otherwise, you will become too small sized. Beans, Tofu, mushrooms and milk contains relatively high amount of protein. Better take more these kind of food. Also, remember to take the Vitamin B12 supplement to ensure you absorb enough Vitamin B12.
I also want to be a vegetarian but sometimes it is quite difficult to find the retaurant and sometimes it gives inconvenience to other people. So, I only try to have more vegetables than meat. Vegetable is very very good for our health.

To my understanding, Vitamin B12 is present only in red meat. So, I do not think you can absorb enough B12 by just taking some fish.
