More and more they are showing up in greater and greater numbers. Bates also reported that freshwater organisms are showing up in the lower portion of the channel. Migration from upstream takes the organisms through the portion of the Channel having the lowest level of dissolved oxygen. It can be concluded, therefore, that conditions have improved or the organisms would not have made it to the lower reaches. The increase of fish during the past year has been reported at the TWQB monitoring station located 11 miles upstream from Morgan's Point.
Croaker is the species found in the largest numbers in the nekton screens.
Crab is next. Others include bass, bluegill, butterfish, catfish, drum, flounder, menhaden, sand trout, and sheepshead. One would assume by this increase in numbers and the diversity of organisms that the water quality is getting better. It is a safe assumption. It is real monitoring.
