Shadows distorted and enlarged upon rendering When I render the scene, the shadows of the fish have become distorted and enlarged. I have played around with the shadow settings on the meshes, materials, textures and environment but cannot fix the problem. Any help will be appreciated. Thanks.
It appears from your image that you have two lamps lighting the scene. The properly sized shadows from your sun lamp are visible, but you also apparently have a spot lamp near the surface of the water, and that is causing the enlarged shadows. Look in the Outliner panel to make sure you have this spot lamp disabled.
