Now, please dont go sayng if Gai, Rock Lee, Neji, and Tenten barely beat 30%kisame, shika has no chance. Gai had to protect the 3 at the same tim as attacking. Gai would have done a lot better if his ninjas werent there, so he wouldnt need to protect them. Also-Kisame does not have his Samehada, no chakra sucking sword. The battle takes place in plains, with a small lake (like 10 feet deep and 30 feet across).
