Tracing its roots to the Nile River, "Tilapia" is actually a group of species within the tilapiine cichlid genus. Tilapia has been farm raised for decades and is cultivated in warm waters across the globe. Sometimes called "St. Peter's Fish", the tilapia is, according to legend, the one fish that Jesus of Nazareth used to feed the masses. Whole tilapia normally range from one to two pounds in size.

Halibut is the largest of all flatfish; the largest halibut grow up to eight feet long and four feet wide, and weigh over 600 pounds. Market sizes typically range from 10 to 100 pounds. Pacific halibut are found along the Pacific Coast from Northern California to the Bering Sea, and westward to Russia and the Sea of Japan. They are primarily taken by longlines in Alaska and British Columbia.

Catfish farming started in Arkansas in 1960 and expanded exponentially as soybean and rice farmers built ponds and processing facilities. Most catfish farms today are located in the Mississippi Delta. A typical pond covers 16 acres and produces 4,000 to 7,000 pounds of catfish per acre. As a rule, U.S. farm-raised catfish are antibiotic and hormone free, are recommended by the National Audubon Society as a safe environmental choice, and are listed as a best choice by the Monterey Bay Aquarium.

Chinooks, also called “kings,” are the largest and most prized species of Pacific salmon. They are the most expensive of all salmon species and are often found in upscale restaurants and better supermarkets. Most Pacific salmon spend one to three years at sea; kings can stay out as long as five years before returning to where they spawn. Chinooks are harvested primarily by trawlers, but are also fished by seiners and gillnetters. They can reach upwards of 50 pounds, but the bulk of the commercial catch ranges between 11 and 18 pounds.
