Overfishing

The Dam Problem with the Decline of Pacific Northwest Salmon For generations upon generations, native Salmon have played a crucial part in the culture of the Pacific Northwest. Native American culture has been influenced and built around salmon. Today, salmon populations are at an all-time low and populations are still plummeting. Many subspecies have gone extinct. Throughout the next several pages, I am going to explore what salmon are, how they have been used, what led to their decline, what…

The data shows that once the round goby was introduced to the ecosystem the native species began to decline. The four native species in lab were perch, bass, bluegill, and walleye. Each species had to use a different utensil to collect food. The perch used one plastic spoon, the bass used two knives, the bluegill used one fork, and the walleye used two forks. In graph one it is shown that the smallmouth bass still survived greatly even with the round goby in the ecosystem. In table 2 the round…

Catfish and largemouth bass are extremely different species of aquatic fish, but their ultimate natural instinct is the same. They strive to survive and produce offspring to carry on the essence of life, as all species do. Catfish are a very docile creature by nature, and their habitat ranges from lakes and rivers to creeks and little streams. They do not always need a fresh and constant supply of flowing water, but it makes for a more productive lifestyle. The catfish also needs good solid…

The fishing line you use in freshwater cannot do well when you’re out in the ocean. This realization hit me one time I got invited to a saltwater adventure. As this body of water is practically endless, the fish have varying weights. They can be as long as your thumb or as heavy as a toddler. You can never assume the size you’ll catch, but you bet I didn’t get any when I took the line for lakes that day. This is enough reason for you to learn how to select a saltwater fishing line properly.…

A. Title The effect of type of net on reducing bycatch B. Introduction/Purpose “ Demand for seafood and advances in technology have led to fishing practices that are depleting fish and shellfish population around the world. Fishers remove more than 77 billion kilograms (170 billion pounds) of wildlife from the sea each year”( National Geographic 2015). The depletion of fish across the globe could lead to many economic and environmental issues if the amount of bycatch is not reduced…

The population of sharks has been in a steady decrease since the 1950s and now one third of the shark populations is extinct. The decreasement of sharks has been linked to the increase of deep sea fishing in countries all around the world. Another reason for the downfall of the shark population is how long it takes for sharks to breed in the wild. If the world does not stop killing off sharks, the ocean and world will be an entirely different place. People are the main reason that sharks are…

All tastiness aside, the discrepancy in funding for protecting different species in the case of Chinook salmon and steelhead makes perfect sense. Salmon is the lifeblood of the pacific northwest. It feeds the forests, wildlife, communities, and the economy. It is no surprise that nearly 80% of funding was devoted to these two species. Populations of Chinook salmon and steelhead have declined rapidly since the 1980s and it appears despite our best efforts they are continuing to decline. Chinook…

A threatened species is one that is in danger of nearing extinction throughout a portion of its range. A geographic range, or a species range is the area in which a species lives on Earth, including their places of migration. Enhydra lutris nereis, commonly known as a southern sea otter, has been a threatened species since 1977 under the Endangered Species Act (ESA). The southern sea otters live in waters along the California coastline. Their geographic range begins in San Mateo County in…

Damnation: The Removal of Dams Project Name: Institution Affiliation: Date: Damnation This documentary focuses on the eco-system and targets the environmentally conscious public. The movie debates in regards to the United States of America (USA) as a Dam Nation and how the existence of more than 75,000 dams in USA has a negative impact on water consumption and the fish species. Knight and Rummel attempt to explain the pros and cons of dams. The movie also features the tale of salmons, which…

The water temperature takes a plummet. The scorching sun boils the water and makes temperatures sky rocket. A cold front is rolling in. Drought has stricken the area and water levels are dropping. Conditions are bad. The sudden change of environment disrupts the normal routine of the bass. With the fishing trip dampened what do you do? How can you still catch fish? What are the types of fishing technique to coax a fish into biting? Water temperatures are down as winter approaches.…
