Our goal was to identify habitat, fish species, and fish assemblages associated with the occurrence of Topeka Shiners Notropis topeka in stream and off-channel habitat (OCH) of west-central Iowa. Fish assemblages and habitat characteristics were estimated in 67 stream and 27 OCH sites during 2010...

Behaviour may also be responsible for the fact that trout under 10 inches in length do not utilize, as food, even small shiners to any extent, even though under laboratory conditions they will kill and eat them. The estimated annual kill of shiners by predatory trout is 150,000 and the ...
The red shiners are often used as bait by fishermen. But in ponds, they can become food for other fish very quickly. Be careful not to put predatory species next to these fish and pick some more peaceful smaller species instead. The red shiners are well capable of adapting to various envi...

2015). This effect potentially increased the biomasses of Chironomidae larvae, which are common food sources for all three buffalofishes. This possibility in lower White River oxbow lakes might explain our observations with buffalofishes, and perhaps also freshwater drum. Three common gar species (...
food, but they also spent more energy searching as routes were longer and less direct, and fish were more likely to search the same area again. We also observed that it took longer for fish to leave the shelter area and enter the more open test area. For some species of juvenile fish ...
Include at least four species of native plants and four species of animal life, such as whirligig beetles, freshwater shrimp, tadpoles, water snails, and golden shiners. After 60 days of observation, discuss with your counselor the life cycles, food chains, and management needs you have ...
Understanding variability of contaminant bioaccumulation within and among fish populations is critical for distinguishing between the chemical and biological mechanisms that contribute to food web biomagnification and quantifying contaminant exposure risks in aquatic ecosystems. The present study examined the relat...
Shoals of 12 golden shiners, Notemigonus crysoleucas, were trained to expect food around midday in one of the brightly lit corners of their tank. They displayed daily food-anticipatory activity by leaving the shady area of their tank and spending more and more time in the food corner up ...
