Yajirobe needs several fish, in this new sub story of Dragon Ball Z Kakarot. At the end of your harvest, you will win an extra senzu bean.
Yajirobe and Korin
After your game of hide-and-seek in the first saga, Yajirobe now needs some particularly big fish, goliaths, especially the scarlet ones. To harvest what you need, simply turn to the fishing spot next to the man, then throw your tail until you have everything you need. Goliaths have their fins sticking out of the surface of the water.
The scarlet version is rarer, but it's the spot where we managed to catch everything (after about fifteen captures). Simply avoid using bait that increases the chances of golden fish appearing. No soul emblem this time again, but a trio of D medals.
