Otters can quickly and easily eliminate entire prized fish populations from a pond. They consume a lot of food daily. Otters have been known to kill and eat large numbers of small fish and invertebrates, including frogs, salamanders, crayfish, snails, and other small aquatic animals. This is especially true in ponds with a lot of vegetation.
In this case, the predator will simply leave the area and return to the same pond several days or weeks later to feed on the remaining fish population. If your pond is healthy, you should not see any signs of disease or infestation. However, if you do see signs, it is important to take action to prevent further damage. First, check to see if the water is clear of algae.
