11-29% of Sockeye Salmon that crossed between commercial fisheries in Bristol Bay, Alaska, were injured from previous commercial gillnet entanglement, resulting in reduced survival and impaired reproduction. More than half of injured fish did not spawn, despite being from spawning populations, which means the estimate of spawning individuals is too high by at least 5-15%.

Adult cutthroat trout in the Salt River watershed were tracked from September-October 2005 until August 2006 using implanted radio transmitters. The fish were caught in the main river stem, spent October-March largely sedentery in pools, started to move more in April and then increased May-June for the spawning season, when 44% of the 43 fish remained in Salt River in April 2006, 37% moved to mountain streams, and 19% into spring streams, almost all preferring streams with manmade pools and gravel-cobble riffles. The fish didn’t use streams that dewatered in the summer or were blocked by manmade barriers.

12 protostelid (microscopic slime mold) species were found in 15 samples of aquatic and terrestrial litter taken from northeast German ponds, 90% of species (including all of the most common) being found in both types of litter. Terrestrial litter contained more protostelids (14% of cultures) than aquatic litter (12%), and the water column contained none.
