You can just make a box with one end open (for the sharks), make another box by it for you above it, fill you box with water, then make a  large box without water ( Drain it )  right under the shark`s box. Then, wait until sharks/ orcas come in. When the come in, build a last side, trapping them in. Then mine a block under the sharks box and let the water Drain. When the sharks can't move, open the box and kill the sharks.
