The global consumption of fish has hit a record high, reaching an average of 17kg per person, a UN report has shown. Fisheries and aquaculture supplied the world with about 145m tonnes in 2009, providing about 16% of the population's animal protein intake.he global consumption of fish has hit a record high, reaching an average of 17kg per person, a UN report has shown.

General Consumption. Based on a freshwater fish only aquarium at about 72 F, the total consumption for a small tank (10 Gallons) is about 150 kWh a year. A medium tank (30 Gallons) will run between 150 â 200 kWh per year, while a large aquarium (55 Gallons) needs 200 â 400 kWh per year.These values are calculated while considering the basic equipment required and serve as an average only.owerheads, air pumps and filters are low in consumption starting at only 3 Watts and generally not exceeding 25 â 50 Watts for the heavy duty models. UV filters run between 8 â 130 Watts and up. Generally spoken, a fish only aquarium runs on a rather low cost.
