Text 1 A hatchery released a record number of young fish into a river, but only a small percentage returned as adults. Surveys found that warm water and limited spawning gravel remained major problems. Text 2 A tributary restoration project released fewer hatchery fish but added shade, reconnected side channels, and improved spawning beds. Survival through the first year rose after the habitat work. What conclusion about fish stocking and habitat recovery becomes supportable when information from both texts is combined?
