A Mongolian legend tells of a giant Taimen trapped in river ice. Starving herders were able to survive the winter by hacking off pieces of its flesh. In the spring, the ice melted, and the giant Taimen climbed onto the land, tracked down the herders, and ate them all.

Tiger barbs have a strong need to be in large groups. They are highly social and will only thrive when kept in groups of eight or more. A school of tiger barb fish will develop a pecking order, similar to a pack of wolves or a pod of dolphins. If you learn to discern the differences between your tiger barbs, you will see that they eat in the exact same order every time.

Rohu is a pure vegetarian fish; however, their food preference changes with the change in their age. The diet of rohu fry consists mainly of zooplankton, whereas rohu adults feed on phytoplankton and submerged plants. They also like to feed on bread, which is hence used as bait to catch them on a hook. In their organic environment, this fish mainly feeds by sieving the water with the help of their thin hair-like gill rakers. Since they do not have any teeth in their jaw, the fish feeds by nibbling the food using their mouth.

Cisco are sometimes called the "canaries of cold water." They do not tolerate warm water or low oxygen levels and have declined in, or disappeared from, over 20 percent of their native lakes in Michigan. Development and other land use changes can lead to increases in the nutrient phosphorus. Increased nutrient levels accelerate plant and algae growth, which in turn drives greater decomposition below the thermocline of stratified lakes, depleting oxygen required for cisco to thrive. Inland lakes that do retain high water quality are often stocked with trout, which also require cold oxygenated water, or other gamefish. Stocking predators or competitors is also recognized as the cause of cisco decline in some inland lakes.

The Asian Swamp Eel, was introduced by unknown sources to ponds at the Chattahoochee Nature Center (CNC) in the mid-1990's. The eels at the CNC are one of only five populations found in the United States, the others being in Hawaii and in Florida. It is possible that they were introduced when someone dumped a fish tank. Another possibility is someone intentionally introduced them in an attempt to establish a food source. As with any invasive species, the eels present a threat to native species by disrupting their interactions with their natural habitat. Beyond not being a part of the natural ecosystem, they have several traits that make it a bigger threat. They breathe air, and are capable of withstanding harsh environmental conditions. During periods of drought, they burrow into the ground. They are able to colonize unconnected bodies of water via overland migration. Because they are active at night, they are difficult to detect and capture. They are also tolerant of cool water, such as that of the Chattahoochee River.

It is entirely possible to use hot dogs as bait instead of the normal options of night crawlers, crickets, etc. Now it is not likely the fish will eat the hotdog but all you really need is enough time for your catch to get caught on the hook. This method is especially effective on catfish, carp, northern pike, and bluegill because they're all opportunistic feeders. If you are going to use hotdog as bait it should go without saying using the the entire hotdog per cast is incredibly wasteful and it's better to rip off small chunks as fish aren't picky about hotdog serving sizes.
