A Description And Some Results Of A Florida State Wide Fish Tagging Program

During the period 1960-1962 a state-wide fish tagging program employing substantial rewards to sport fishermen for tag returns was conducted in Florida. A total of 19,470 fish including 5,328 largemouth bass were captured, tagged, and released. There were 24.2 percent of the tagged bass, 4.5 percent of the bluegill, 3.8 percent of the shellcracker, and 8.9 percent of the crappie returned. Little difference in returns was noted between fish which were transported prior to release and those which were released into the waters from which they were captured.

Preliminary Results Of Several Herbicides On Aquatic Vegetation In Florida

The 1957 Legislature expanded The Florida Hyacinth Control Program to a Noxious Vegetation Control Program. This made testing of herbicides for the control of other noxious plants necessary. A convenient field test of herbicides was developed. These herbicides were tested using disel oil and/or water as a carrier. The herbicides tested were Atlas "A" (sodium arsenite), Amino Triazole (3 amino-l,2,4-triazol), Aquaherb (orthodichlobezene and aromatic salt), Aqua San (trichlorobenzene and aromatic petroleum distillate), Ammate (ammonium sulfomate), Atlacide-2,4-D (sodium chlorate-2,3-...

Experimental Use Of Explosives On The Aucilla River

Seven charges of Nitromon Primer S were exploded at six stations on the Aucilla River. Results of three explosions, each consisting of ten pounds of explosive, at Station No. 1 killed at least 842 shortnose gar, 300 longnose gar and three channel catfish. The successive treatments at this station indicated a reduction of longnose gar in the area. More shortnose gar were destroyed in the third explosion than in the first and second. Variation occurred in the results at other stations. It was noted gar concentrations could be detected by their surfacing activity. At all stations where...
