Painted fish

In his original findings, John Endler (1978) reported that male guppies in high predator areas tend to have patterns that resemble their environment so they don’t stand out. Guppies with low or no predation, tend to not blend in and are brighter with more and larger spots (Endler, 1978). Endler thought that this could be happening because color patterns are molded by natural selection and sexual selection. Although brighter males are often preferred by the females, they are also more likely to…

It was a gloomy day. I was at our Subdivision’s Local Beach getting ready to swim out to the raft with my four friends. The “raft” as we called it was the bottom end of a Pontoon Boat anchored in the center of Dollar Lake. Occasionally the rain and winds blew it. When my friends arrived we dove into the shallow end of the beach and acquainted our bodies with the cold, late Summer temperature. After a few minutes my friend Gage shouted, “Let’s Go!” and the four of us swam onwards toward the raft.…

The Caribbean spiny lobster Panulirus argus (Latreille, 1804) supports the most valuable fishery in Cuba, and generates a net income of around US$70 million per year, it provides direct employment to 1,110 fishers and indirect employment to approximately 7,800 people (Puga et al. 2006). The total catch of spiny lobster grew until the early-mid 80s, when reached about 12,000 t. In the early 90s, landings decreased along with the Cuban economy, but by the middle of the 90s it began to recover, but…

3/27/2017 Overfishing means to reduce a fish population to the point where it cannot sustain or barely sustain itself.

We now know without a doubt that the fish in the ocean are a finite resource…

Hemingway. To go more in depth, in his journey with the marlin he took in pride in never giving up on trying to catch the fish even with the ongoing pain he had to deal with. Along with pride, he also had faith by never giving excuses to himself to give up, and always thinking positively. Also, he shows his pride mostly when he finally caught the marlin after a 3 day battle with the fish. Overall, the novel The Old Man and the Sea showcases the theme pride. Like I said earlier, one of the…

Each late spring, individuals run to the Great Lakes to swim and fish in the apparently unbounded waters and climb along the untainted shores.

In The Death and Life of the Great Lakes, writer Dan Egan portrays how the lakes' characteristic history offered route to an unnatural one. From the impacts of worldwide exchange and…

there will be competitive exclusion between the fish and ducks. Competitive exclusion does not only mean that one species is killed off it also means that it can “also result in two species sharing different parts of a niche”(pg.249). The ducks and fish don’t share the same ecological niche which is “the part of the environment that a species uses to survive and reproduce”(pg.248). This is also proven by the fact that it states in the textbook that “the fish use a different part of the habitat’s…
