The majority of the crawdads were on the small side to begin with and once the 20 GSF that I added to the pond spawned and made many, many more GSF, recruitment of the crawdads was greatly diminished. The GSF were introduced and 2 years later the pond was drained and there were hundreds, maybe thousands of GSF from 4 inches long down to YOY. I believe it was the predation of the very young crawdads that led to the significant reduction in population.
