Zhang Yang didn't plan to spend too much time fishing at this reservoir, so he didn't prepare to put too much bait into the water all at once. It's not about saving bait, but rather if too much is used at once, it could kill the spot, and it might take days for the spot to become active, by which time Zhang Yang and his team would have already left, rendering it ineffective.
In contrast, Zhang Yang's strategy was to create multiple fishing spots around the chosen location, but with less bait, replenishing often. This way, they could test fish behavior first and then make targeted adjustments.
