This level has medium difficulty. For this level try to play more near to blockers or from the bottom part of the table to shuffle the candies. Combine them with each other to break more snow blockers or play near to snow blockers to find the bears.
My level 776 has reward for catching fish but does not keep track of how many you have except if you don’t complete it tells and asks if you’d like to keep going to catch more fish. You do, you complete the level with the required fish and it just says Next. No tips site mention fish and it’s every level on recent release of 766+.
