Create a detailed black and white vector illustration in vintage engraving style showing a large grizzly bear catching a fish from water. The bear is positioned centrally, leaning down towards the water with its mouth open showing teeth and fangs, holding or about to catch a fish (salmon or trout). The bear should have extremely detailed fur texture with individual hair strands visible, especially around the head, neck and shoulders. The water surface shows realistic ripple effects and reflections. Include grass or reeds at the water's edge in the foreground. The composition should be vertical/portrait oriented. Style: Classical engraving technique, heavy crosshatching for shadows and fur texture, high contrast black ink on white background, woodcut aesthetic, naturalistic wildlife illustration from 19th century natural history books. The bear's expression should show concentration and predatory focus. Background should be minimal or white to keep focus on the bear. No grayscale - only pure black lines and white space.
