Fly-fishermen use artificial insect imitations (flies) to catch trout, and typically release them again in order to have the fun of trying to catch them again later. One fisherman claims that due to the “catch-and–release” practices, the trout are becoming harder to catch, and explains that the ability to detect fisherman’s flies is being passed on by released trout to their offspring, making them harder to catch. Explain whether he is right or wrong.

Expert Solution

When fisherman first time trap them through flies as bat then the stuck due to unknown event of life but when fisherman play with them catch, release and throw in the water body again and catch them again. This provides a sort of experience to them and they used to it and eventually understand the trick. Next time whenever they see a trap for the same, they ignore the bat and save themselves from fisherman as they learnt that it is a fake organism to lure them. Trout also exhibit behavioural changes and this is once of them and not only they prevent themselves but also alarm other member also and warm them not to indulge in such kind of activities orchestrated by the fisherman.

Schooling is one of the rationally advantageous behaviors in fishes wherein they teach their offspring and prepare them for avoidance of such events of occurs through release of pheromones (a kind of alarmign chemical).SO, the statment made by fisherman is correct.

Use SAS to answer the question: Researchers have studied bears by anesthetizing them in order to obtain vital measurements, such as age, gender, length, and weight. Because most bears are quite heavy and difficult to lift, researchers and hunters experience considerable difficulty actually weighting a bear in the wild. Data in the following table represent the body length and weight of eight male bears. x, length (in.) 53.0 67.5 72.0 72.0 78.5 68.5 73.0 37.0 y, weight (lb.) 80 344...
