The ponds at Floyd Lamb Park have been giving up bluegills as well as largemouth bass though the surge in daytime temperatures has slowed things down. Recently planted catfish have experienced a substantial die off, probably due to transportation related stresses, said Jon Sjoberg, supervising fisheries biologist for NDOW. No other species has been affected at this time. NDOW is investigating the situation and working with the vendor to arrange for replacement fish.
