Threadfin Shad Survival

The start of 2014 rang in the coldest temperatures that in over a decade. For those with threadfin shad, the bitter cold could have led to the demise of your threadfin shad population. Threadfin shad are great bass forage but they die once the water temperatures reach the low 40’s especially if the water temperature stays too cold for too long. Ice may equal dead shad. However, just because some shad die off does not mean that the entire population died off. In deeper lakes, shad can survive by seeking out thermal refuges that provide warm enough water temperatures to get the shad through the cold winter.

The best key to determine how the shad fared through the winter is by conducting an electrofishing survey this spring. You can also look for schooling shad at the water surface in the evenings once the weather begins to warm.  If a majority of the threadfin shad population or the entire population was eliminated, shad can be re-stocked this spring. Remember that we only stock shad when they are ready to spawn which increases the establishment of the shad since they will spawn shortly after being stocked. Typically, our shad stockings occur in April through June. Because of timing the sooner we determine the status of the shad the better the chances of stocking this spring.

** Though thick ice in north GA leads to rare kids fun activities (with safety measures in place), this particular ponds was covered in thick ice for four days. If you experienced heavy ice cover similar to this, you threadfin shad population likely did not survive unless the pond has a high abundance of deep water; and yet their chances of survival are still limited in such a severe ice cover. Also, we don’t recommend walking on ice in the south due to thinness of ice.
