5-7" Fingerling Channel Catfish
These fish are one year old and ready for stocking into a food-fish production pond or into a stocker pond if using a modular system.
The "sock saver" (center front in the photo) being used during a commercial pond harvest. The tanks (Dewars) hold liquid oxygen or LOX which is supplied to diffusers in the sock holding the fish through the green lines. This can increase the dissolved oxygen by one part per million resulting in greater survival to the plant as well as improved product quality.
Fingerling channel catfish being loaded on a transport truck for delivery/stocking in another pond.
Eggs being hand-stripped from a female channel catfish. A blue catfish sperm solution will be added to produce a hybrid channel X blue catfish. This hybrid has several apparent advantages over pure channel catfish and are bring studied by scientists at the CGRU.
Catfish spawn in cavities in nature. In commercial production we place spawning containers (to the right in the photo) in ponds containing catfish broodstock, and periodically check them, removing any egg masses we find. The egg mass being held by this scientist will be placed in the bucket of disinfectant prior to delivery to the hatchery.
