Salinity
Salinity is the dissolved salt content
of water and is often expressed
as the parts of salt by
weight per thousand parts of
water by weight (ppt). Channel
catfish can breed and reproduce
over a wide range of salinities.
Eggs can hatch and fry will develop
in waters with salinities up
to at least 8 parts per thousand,
but the optimum salinity for channel
catfish hatchery supplies appears
to be between 0.5 and 3 ppt
(500 to 3,000 ppm).

Hybrids HSB are
generally stocked into freshwater systems
but they do well in salinities of
O to 25 ppt, and some can survive
salinities up to full strength seawater
(35 ppt).
