Step 1: Combine all ingredients in a 6 quart stock pot. Bring to a boil, partially cover the pot, turn the heat to medium-low and simmer for 30 to 40 minutes.
Step 2: Strain the stock through a fine sieve into a large bowl, pressing down hard on the vegetables and fish trimmings with the back of a spoon to extract their juices. Discard solids.
Step 3: Wash the pot and return the strained stock to it. Reduce the stock to about 6 cups by boiling it rapidly, uncovered, for about 20 minutes.
Step 4: Restrain through a fine sieve or through a double thickness of cheesecloth lining a regular sieve.
Step 5: Use for soup or freeze for future use.
