Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold. This allows overfishing to be a problem.
They thrive during the day and the warmer months of the year. 5. . a. N= (100*100)/36= 277.77 ~ 288 individuals in population b. Yes, the yellow tang is a species of saltwater fish.
They both have unique characteristics that make them completely different things. I’m going to prove that all fishing is not the same, saltwater and freshwater fishing are different sports based on dangerousness, cost, species, bait, and boat type. Most people assume fishing is a safe and easy hobby, however, fishing can actually be a dangerous activity. Saltwater fish have the potential to pull you into the water, bite you, or even sting you. On a fishing trip in Florida, my
Cuttlefish are marine organisms which classified into animalia kingdom. They are grouped into spiida order and cephalopoda class. The common cuttlefish are scientifically known as the Sepia officinalis. The cuttlefish fish possess W-shaped pupils, 2 tentacles which consist of the denticulated suckers. They vary in sizes.
The introduction of Asian carp into the Great Lakes has had an adverse effect on native fish and could jeopardize the fishing industry, particularly lake perch and trout populations. The Asian carp eat many tiny plants and animals, which are food for many native fish. This will eventually affect the population and growth of the Great Lakes native fish. The Asian carp should be removed from the Great Lakes as shown in the following paragraphs.
After a plethora of studies made we know quite a bit about the ocean and the creatures that live there. We know who is the prey and who is the predator, what temperature some live in, and where they live. We know so much about the ocean and its inhabitants, but we also don’t know enough. There is more in the ocean than the things we’ve seen and studied. There’s things deep down in the ocean so deep that light from the sun doesn’t even reach it.
During many years the tons of uncontrolled fish piled up in our markets and homes. To solve this situation and avoid the mislabeling and confusion we must create a system to control the other percent of imported food in order to avoid serious diseases. Loaded with mercury Since we were little kids we were thought that fish is good for us because it is rich in omega 3 fats which will do wonders for our health. Nowadays in this modern society where pollution has reached its highest point we can’t be sure that the food and especially the fish we consume are 100% healthy and clean.
Also, the usage of explosives are harmful because they all kill off things such as coral, and the damaging of coral reefs can take decades before it reverts back to its normal state. To reduce or totally eliminate the way these local practices are impacting the environment, we can place restrictions on what can be used in fishing, and how much you can catch. For example, we can limit fishers to only 10 fish a day. This would give the fish plenty of time to reproduce and would keep the population of the fish steady. Also, we can ban the usage of poisons and explosives.
They can be found swimming around in sea grass fields from the coasts of Africa to Australia and even around South Asia. Their main diet is as many species of sea grasses as it can find. They rarely eat anything other than sea grass but will occasionally snack on algae if needed. They are strictly herbivores as they can eat up to 110 pounds of sea grass a day.
Kelp is one of the very bright, colorful plants found in the ocean. Kelp depends on sunlight and is found no deeper than 131 feet. Oar weeds is another common plant in the Pacific Ocean. Oar weed is a large seaweed that dark brown and can grow to three meters long. Oarweed was used as a fertilizer in the 18th century.
Sea lice are parasites that occur naturally on many different fish but due to the condition of being farm raised they spread faster and even fish in the open ocean passing by the the farms are being infected. This in turn effects other fish in the ocean. The fish are often given pesticides to combat sea
European colonists in the Atlantic began massive fishing for fish, and Atlantic Salmon was a common victim of these harvestings. Since then people have been overfishing for salmon, making
The first one that the beluga will pass through is called Epipelagic Zone or the "Sun Light Zone". When a beluga dies it gives nutrients and food to all the animals and life that is there. The second layer it goes through is called the Mesopelagic Zone or the "Twilight Zone". Many of the beluga isn 't left by then but the nutrients of other fish and the beluga still continues to float to the next layer of the ocean. The third layer of the ocean that the beluga falls through is called the Bathypelagic Zone also known as the "Midnight Zone".
Beaches, docks, and other shallow, oxygen-rich areas provide a suitable habitat for the clams. Because of this, Asian clams greatly impact swimming areas since their sharp shells can cause injuries among swimmers. Also located in shallow areas of lakes, typically, are water intake systems, which Asian clams also have the tendency to clog and ultimately destroy. Since the town of Lake George 's main drinking water source is the lake, this creates a huge issue. The clams also clog water intake systems in private boats and homes, costing owners hundreds of dollars to fix.
A question that many wonder about is why is phytoplankton important? Plankton is revealed by ocean color and help show scientists where ocean currents provide nutrients for plant growth. They also help show where pollutants are poisoning the ocean preventing plant growth and where changes in the climate of the ocean are occurring. Plankton is also the foundation of the oceans food chain. As phytoplankton begin to grow and multiply, small fish eat them, then the larger animals begin to eat those smaller animals.
