During the 1970s Texas Parks and Wildife Department investigated Lates
for possible stocking in pumped storage power plant cooling reservoirs
in S. Texas (Lake Braunig near San Antonio for one). The venerable
Clark Hubbs traveled in Africa looking-in-populations of the fish for
TPWD. Their reasoning then was that the reservoirs are "closed," to
any nearby ecosystems, since water is pumped into the reservoir rather
than the thing being a dammed stream. So, supposedly, no escape into
nearby waters would ever occur. Also, they thought that in the event
that the introduction proved undesirable, they could simply kill all
the fish by shutting off the power plant during winter. Seems to me
that the power company might have a thought on that, though. I don't
know what Clark's report said, but I don't think TPWD ever followed
through with stocking them. I am sure they are not present in the
Texas fish fauna today.
