Weight and Length
Hardhead catfish weigh on average one pound and measure ten to twelve inches long.
As hardhead catfish grow longer, they increase in weight. The relationship between length and weight is not linear. The relationship between total length (L, in inches) and total weight (W, in pounds) for nearly all species of fish can be expressed by an equation of the form:
Invariably, b is close to 3.0 for all species, and c is a constant that varies among species. The relationship described in this section suggests that a 20-inch hardhead catfish will weigh about 3 pounds, while a 25-inch hardhead catfish will likely weigh at least 6 pounds.
