American Eels Habitat and Extinction Research Paper - 1

American Eels Habitat and Extinction - Research motif ExampleOne of the peculiarities of these eels is the regular basis of migration. In other words, they may not stay in a particular location for longer periods. They like to travel from rivers to river since it like fresh water truly much. It stays major portions of tis life in rivers or fresh water sources and visit ocean in general for spawning or laying eggs. A female eel can lay eggs as much as four million every year. However, after the egging period is over, it will suffer immediate death. Lafontaine et al. (2008) vex pointed come out that Since the 1980s, the American eel (Anguilla rostrata Lesueur) fisheries have declined dramatically in the Lake OntarioSt. Lawrence River watershed providing evidence of a large decline in population of this species (Lafontaine et al., p.185). American eels are decreasing in twist over the last few decades because of heterogeneous reasons such as climate changes, global warming, water pollution etc. Even though, the decline of eels have been noticed as early in the 1960s, the problem became intensified in the 80s and 90s. Eel landing started to decline considerably during the latter parts of the twentieth century, especially 1980 onwards. The decrease in the number of eel landing was calculated based on the catch per unit effort (CPUE) effort.
