I noticed on my small pond that the bass nests have been abandoned without any of the eggs hatching and now I have the same cruising bass along the shore. I am only guessing here but maybe the water temps have to reach, or be at, a certain temp before they can hatch. With the cold and rainy spring maybe those kind of conditions were not met and the nests failed. In any case, there are no active nests nor any fry balls anywhere in my pond. I am anticipating a new round of nesting by those still ripe once the weather settles down in June. Just a guess.
