The condition index in fish is a way to measure the overall health of a fish by comparing its weight with the typical weight of other fish of the same kind and of the same length. The condition index is its actual weight divided by its expected weight, times 100%. A fish of normal weight has a condition index of 100 percent.
Weight and length of walleyes. Walleyes grow to about 80 cm (31 in) in length, and weigh up to about 9 kg (20 lb). The maximum recorded size for the fish is 107 cm (42 in) in length and 13 kilograms (29 lb) in weight. The rate depends partly on where in their range they occur, with southern populations often growing faster and larger.
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.

Weight vs. length for channel catfish, where b = 3.2293 and = cm [15] An average adult channel catfish measures at least 12 inches (30 centimeters) long, and weighs between 2 and 4 pounds. The largest specimen on record weighed 58 pounds and was caught in 1964 by an angler in South Carolina.
Adult male American alligators measure 3.4 to 4.6 m (11.2 to 15.1 ft) in length, and can weigh up to 500 kg (1,100 lb), with unverified sizes of up to 5.84 m (19.2 ft) and weights of 1,000 kg (2,200 lb) making it the second largest member by length and the heaviest of the family Alligatoridae, after the black caiman. Females are smaller ...
They commonly reach 3 m (10 ft) in length, and the maximum reported is 4.55 m (14 ft 11 in) in length and 682 kg (1,500 lb) in weight. [ 4 ] [ 6 ] [ 11 ] The International Game Fish Association 's all-tackle angling record for a swordfish was a 536 kg (1,182 lb) specimen taken off Chile in 1953. [ 3 ]
Attaining a maximum length of 2 m (78 in) and maximum weight of 79 kilograms (174 lb), the cobia has an elongated, fusiform (spindle-shaped) body and a broad, flattened head. The eyes are small and the lower jaw projects slightly past the upper. Fibrous villiform teeth line the jaws, the tongue, and the roof of the mouth.
