The PFBC stocks approximately 3.2 million adult trout, 650,000 fingerling trout and supplies about one million fingerlings to cooperative nurseries each year. The production process begins about 1.5 years before stocking with a goal of producing those numbers of adults and fingerlings. Fisheries Management submits requests to the hatchery program each fall for the specific numbers, species and locations of fish to be stocked the next spring. Hatchery staff grade and inventory those fish multiple times throughout their time at the hatcheries to meet the stocking requests and provide trout to the anglers of PA.
When dealing with a live product for a length of time, there will be some variation within our inventory due to issues such as predation, cannibalism, disease, etc. If the hatchery inventories are 99% accurate, we may be off by 32,000 fish or so. Typically, by the end of stocking season, this is the case and inventories are off slightly and stockings need to be adjusted. If our inventories are a little shy, we will usually cut the end of in-season stockings by a small percentage across the board. This ensures that all scheduled stockings are still met and fish are where the anglers expect them. If we are over a little, sometimes fish can be added to a stocking but usually our stocking trips are scheduled in a way to maximize truck loads for efficiency and there is little room for extra fish. We must use caution if we think we have extra fish because if we are off by just 1% and have less fish than expected, some stockings may not be completed by opening day. If there are any fish to be stocked after the scheduled stockings are completed, Fisheries Management supplies us with a list of water bodies that are suitable for June stockings. These waters are some of our coolest stocked trout waters. Some of these waters are then chosen by the hatcheries for stockings because of proximity to the hatchery where the fish are located. Of course, most of the coldest waters out there are some of our Class A trout waters and would not be available for stocking.
In the case of the stocking in this thread, Oswayo SFH had some trout left at the end of their assigned stockings. Even though it’s thousands of trout, it is a very small percentage of the entire production of millions of trout by our hatcheries. Kettle Creek Lake and Kettle Creek section 5 were two of the waters recommended for late season stockings. A stocking truck from Bellefonte SFH was sent to Oswayo SFH, picked up the fish, then met the WCO at Kettle Creek Lake. The lake temperature was high and the coolest spots they could find were 74 F and they checked the stream and also had a high temperature (74 F). The WCO decided to go to the coolest part of the stream below a tributary which was 70 F. We prefer to stock trout in a maximum of 68 F, but this appeared to be the coolest temperature water they could find in the area. The WCO and stocking truck driver then used water from the stream to temper (or help equalize) the water temperatures between the stocking truck tank and stream. Tempering is a common practice during stockings and once the temperatures were within the acceptable range, the decision was made to stock because the fish were exhibiting some stress on the truck. The WCO and driver reported approximately 40 dead trout at this stocking. PFBC staff strive to rear and stock quality fish at all our stocking locations. If more trout died after the stocking, they were not aware of it. We do not want to have any fish mortality taking place and these late season stocking are sometimes difficult. Some posters in this thread recommended specific waters that could have been utilized and many of those waters are included on our list for late season stockings such as the Allegheny River and East Branch Clarion River. Not all late season stockings can take place on a couple of waters or the number of stocked fish would not be reasonable. We regret that this incidence occurred and have taken measures to ensure that all late season stockings will occur in waters that are 68 F or below and maintain those low temperatures.
