Yes. Slap on the Zora Mask and get in the water. Just keep ramming into him with the electric shield, and he'll be dead before you know it. That's the easiest way to kill him.
If you don't feel like being cheap, you can fire arrows at him from the edge while he's ramming into the platform and and then he'll be stunned. Slap on the Zora Mask and dive into the water, then swim into him (use the shield for a split second to damage him) and then as soon as you get him, dolphin jump onto the platform to avoid him chomping on you and doing major damage.
Good luck.
