physics help!

hi everyone! ok so i was doing my homework and i came upon this one problem which completely stummped me and so if someone could set me in the right direction i would be very thankful! here is the promblem: If a salmon swims sraight upward in the water fast enough to break through the suface at a speed of 5 meters per second, how high can it jump above water?

So, you're given the initial velocity and asked to find the maximum height. What can you say about the velocity at the top of the jump ? How are initial and final velocities related to distance (height) ?

That's more than I should be giving away at this stage...
