After several months of no rain the wetland overflowed and filled the tank on April 24, 2019. The attached results were taken a week after. The watershed includes at least 2 old saltwater storage ponds from the early days of oil drilling. Salinity was always a concern. The BG appear to be growing well, FH are spawning and I see lots of bugs swimming. The results say very limiting in the wetland (sample 2) and limiting in the main tank (sample 1).
I've heard high salinity can stunt fish growth. Let me know what you think!
The results had to be converted from pdf to Excel so some formatting is off. Is there a way to post pdf files?

Cl (chloride)
Desirable range Acceptable range
More than 100 mg/L (for commercial catfish ponds) 10 times the nitrite concentration (for commercial catfish ponds)
confused with the gas, chlorine (Cl2). Chlorine is a highly reactive compound and is used as a disinfectant. Chloride is the same element in the form of a salt. While chlorine is very lethal to fish, chloride is a component of most waters and is essential in helping fish maintain their osmotic bal¬ance. In commercial catfish production, chloride (in the form of salt) is often added to water to obtain a minimum concentration of 100 mg/L. This is done because catfish and certain other species are susceptible to “brown blood” disease, caused by excess nitrite in the water. Maintain¬ing a chloride to nitrite ratio of 10:1 prevents nitrite from entering the fish, thus reducing the occurrence of nitrite poisoning. Chloride concentrations can easily be increased by adding “mixing” salt to the water. Salt is also often used for the treatment of common fish diseases and parasites. Chloride levels higher than 70 mg/L are a concern if the water is also used to irrigate sensitive land-based crops. Sensitivity to chloride varies widely among plants; contact your Extension office for detailed informa¬tion.

The TAMU article is in different units of measurement. How do the units compare when converted? Do you think my numbers are "limiting" as indicated in the results?

I couldn't open the attachments as either an Excel file or a pdf? It was just a jumbled mess.

A liter of water weighs 1 kilogram (1000 grams). 1 milligram is 1/1000th of a gram. Hence, there are a million milligrams in a liter of water. For water, they are essentially the same. X mg/l = X ppm

I would wait on the pond to settle down and test again.

We just got another inch of rain. The wetland and tank are likely overflowing again. Time for a walk!

Hi Joey - Here are the results. The water sample was taken a week after the big rain from the shore surface about mid pond. Some water was still flowing in but it had really slowed down. Since salt water sinks the bottom could have even higher concentrations.

I've been feeding daily and have yet to see a confirmed CC. 100 were stocked in Oct.

Parameter analyzed - Results - Units - Method
Calcium (Ca) 157 ppm ICP
Magnesium (Mg) 23 ppm ICP
Sodium (Na) 280 ppm ICP
Potassium (K) 9 ppm ICP
Boron (B) 0.1 ppm ICP
Carbonate (CO3) 0 ppm Titr.
Bicarbonate (HCO3) 102 ppm Titr.
Sulfate (SO4-calculated from total S) 45 ppm ICP
Chloride (Cl-) 623 ppm Titr.
Nitrate-N (NO3-N) 0.02 ppm Cd-red.
Phosphorus (P) 0.08 ppm ICP
pH 6.76 ISE
Conductivity 2510 umhos/cm Cond.
Hardness 28 grains CaCO3/gallon Calc.
Hardness 488 ppm CaC03 Calc.
Alkalinity 84 ppm CaC03 Calc.
Total Dissolved Salts (TDS) 1240 ppm Calc.
SAR 5.5 Calc.
Iron (Fe) 0.02 ppm ICP
Zinc (Zn) <  0.01 ppm ICP
Copper (Cu) <  0.01 ppm ICP
Manganese (Mn) <  0.01 ppm ICP

Here are the very first fish caught from my pond - Yesterday! We stocked HBG, BG and RES in Oct 2018 along with CC and FHM. Another 400 BG and more FHM were added in March 2019. Are these all HBG? I caught two others that had small mouths and appeared to be BG. The last pic is of some type of beetle. Notice there is a group of much smaller ones in the top of the pic.
