Most standard weight equations are for freshwater fish species. Weight-length curves are developed by weighing and measuring samples of fish from the population.
In some regions the fish can be raised in rice fields at planting time and grow to edible size (12–15 cm, 5–6 in) when the rice is ready for harvest. Unlike salmon, which rely on high-protein feeds based on fish or meat, commercially important tilapiine species eat a vegetable or cereal-based diet.

Although carnivorous farmed fish represented only 13 percent of aquaculture production by weight in 2000, they represented 34 percent of aquaculture production by value. [101] Farming of carnivorous species like salmon and shrimp leads to a high demand for forage fish to match the nutrition they get in the wild.

For much of the past decade, policymakers and analysts have decried America's incredibly low savings rate, noting that U.S. households save a fraction of the money of the rest of the world.
Its average weight is 5 to 12 kilograms (11 to 26 lb), but specimens weighing up to 100 kilograms (220 lb) have been recorded. Pacific cod are smaller, and may grow up to 49 centimetres (19 in) and weigh up to 15 kilograms (33 lb). Cod feed on mollusks, crabs, starfish, worms, squid, and small fish. Some migrate south in winter to spawn.
