Transporting fish is a very important part of fish culture. Fry and fingerlings must be transported from hatchery to pond for stocking. Brood fish are sometimes transported into the hatchery to spawn. Our plastic fish bags are perfect for bringing fish home from the aquarium. With one open end, these polyethylene aquarium bags can be secured with twist ties for easy transport. It is essential to maintain adequate oxygen in the water while transporting fish. The technique recommended for oxygenating water during fish transport is use of pure bottled oxygen. It may injected into a plastic bag containing water and fish which is then sealed air-tight for transport. When plastic bags are used, oxygen is added after water and fish. One-fourth of the bag usually contains water and fish and three-fourths contains oxygen. After adding oxygen the bag is sealed shut with a twisted rubber band, string or other material. The sealed bag of fish is then placed in a box, woven grass bag or other container for added protection and loaded onto a vehicle for transport. If properly packaged and insulated from heat, these containers can transport fish for 24 to 48 hours without water exchange.
