cfm... actually the injections for springers are of erythromycin to try and stop vertical transmission of bkd(one squirt per 10lbs of fish)..they use a formalin bath on the fish in the ponds for fungus..so no fish from the ponds go to the food bank..treated fish get buried..they used to use malachite green for fungus but it proved to be too nasty...and it stained your hands green for life!..not to mention what it did to invertebrates in the river...
..another reason they may have come up short is because people complain about hatcheries taking too may eggs and not putting enough fish in the river for people to catch and with tighter budgets now there's less money to cover the extra fish...so they have to cut there egg takes closer now ... if they get a disease outbreak or mistake on samples they end up short....no more going for 10+% overage on your egg takes like in the past...
