Taking this single piece of information, imagine how simple predicting a lake's first late winter panfish peak is. You will rarely miss the bet by driving to your target lake, taking a few steps on to the ice to observe the snow conditions, and making your decision from there. If the heavy snow is gone, go for it. If not, head southward, or to a shallower lake nearby. Unless you've got inside information that tips you off to active fish before the snow melt-off, skip trying these lakes beforehand.…
Viruses are NOT cells and much smaller than bacteria and damage the cells in which they reproduce.…
One major problem we are facing as a country is the rapid decline in several different species of fish in the ocean. Some specialist have actually looked into this to determine the cause for the decline in fish in the ocean. One of the major causes is that some species of fish are being fished more than others. It is even stated that more fish than the species are being able to actually reproduce. This alone could eventually lead some of the species into extinction. This is definitely something that can be controlled by humans. Typically, fishing period could stop any and all declines however that is not going to happen. Fishing is harder on the ocean environment then toxic pollution or degraded water quality. As human the only thing we can do if we aren’t going to stop fishing is stop targeting the same fish species to prevent extinction. We need to want to keep the environments balanced and as the primary cause of the decline fish stock in the ocean.…

There used to be much hunting of Phoca vitulina because it was thought that they competed with fisheries. Today, mass hunting of Phoca vitulina is mostly prohibited in the U.S. However, hunting is allowed for Alaska’s indigenous peoples because that is what they eat. Also, the population of Phoca vitulina in the Baltic Sea has greatly decreased because of an extermination program. In Norway, there is a yearly quota set on the catching of Phoca vitulina. There have also been many viral outbreaks that have affected Atlantic populations of Phoca vitulina, as well as an outbreak of phocine distemper in Europe. Also, since many populations of P. Vitulina come ashore in heavily populated areas, they are exposed to a threat posed by wild land animals and pets such as dogs. The population of harbor seals has been gradually decreasing in La…
Did you know that almost eighty percent of the fish living on a reef could be killed by a single fish that is only about the size of a human hand? This fish happens to be called the lionfish and is mostly known for its beautiful features and deadly poison. Lionfish are indigenous to the Pacific Ocean; however, they have recently invaded the Atlantic Ocean and are growing in population at an uncontrollable rate. Marine biologists and even everyday snorkelers fear the dangers of these fish and have even started taking the matters of getting rid of them into their own hands. On the other hand doctors, chefs, and even snorkelers consider lionfish to be very useful and entertaining. According to marine biologists, the…
The viruses is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. viruses can damage you or service users if you get a viruses from a person or an animal being in contact with them…
Starfish or sea stars are marine invertebrates belonging to the phylum Echinodermata; class Asteroidea. Crown of Thorns Starfish (Acanthaster planci) are found on coral reefs in the tropics ranging from the Red Sea, the Indian and Pacific Oceans, and all the way to the Pacific coast of Panama. It plays a major role in the destruction of fast growing coral species. Scientists believe that this starfish has lived on the reefs for tens of thousands of years and when the populations of this echinoderm increase in number, they can seriously damage the coral reefs.…
Because farm-raised fish are kept in crowded pens, they are given high levels of antibiotics to prevent disease. Fish farmers also feed them pesticides to prevent sea lice from developing.…
Smallpox was responsible for an estimated 300–500 million deaths in the 20th century. As recently as 1967, the…
For my final project in Zoology I choose to write about the Starfish and Mussels we dissected. I chose these because, for me, these dissections were the most fun! Seeing what was inside of the starfish was nothing I had thought it would be, and the mussel is something I eat but usually it is mostly cleaned out by then so it was interesting to see what it looked like before it was cooked. As well as dissecting these animals, I was able to learn about how they interact with one another.…
During the SARS outbreak in 2003, many became ill. According to Source B, 8,098 people throughout the world became sick, to an unknown source, 774 of which died. Finally, with precautionary measures, the US Department of Health and Human Services banned the import of civets. Civets, small catlike animals, were thought to be the main suppliers of the SARS disease. The more a person is exposed to the carriers of SARS, the more likely he or she is to become immune with it. (Dybas) The interaction the disease had with not only the carriers, but to another species, humans, and an international outbreak. How could something as small as a respiratory illness travel from continent to continent? Boats, planes, ships, and every other form of transportation of course. The greater the transportation, the higher the risk is for a spread of an unwanted disease, therefore why many cringe at the soul fact of invasive species introduced to new environments.…
Once the virus has contact and successfully entered the mucous membranes, it begins to replicate. Replication of this virus allows the breakouts to become more frequent. The virus is then transported within the nervous system to their roots, where it remains latent,for some period of time. During this inactive periods, the virus cannot be transmitted to another person; medication helps with inactivating this virus. However, at some point, it often begins to replicate itself again cause active periods of the virus. The virus can only be broadcasted to another individual when the HSV is operating. When…
Did you know that vending machines are bigger killer than sharks? And that 10 people are killed by sharks worldwide every year? Yet we continue to kill 10 million sharks every year. Shark culling was implemented in WA in 2013 to protect swimmers, with great whites being targeted, although 50 species of sharks including great whites, are listed as vulnerable, endangered or critically endangered. The system isn’t cheap either with the government paying fisherman $610 000 for 107 days of the catch and kill program. This figure is not including the costs of drumlines and other programs helping the mitigation. We know that the ocean is the shark’s territory and people should need to make the decision whether to take the risk when entering the water. To elucidate my argument, I will explain in three different parts, the damage that it can cause on the ecosystem, the government are contradicting themselves by killing endangered species and that many other things are killing people at a faster rate.…
By the moment when it was spun off its parent company into an independent entity in March 2000, Aqua Bounty had invested about US$ 4 million in developing new technology in aquaculture. Although it made progress in entering Chilean market in that year, this firm soon became controversial because of the property of genetically modification. This technique had not been embraced in animal cultivation by mainstream ideas, despite of its amazing efficacy in raising production of commercial fish. The pivotal approval by FDA was expected to come for another 18 month, with a lot of uncertainty, hence an additional try on shrimps. Hard work pays off. Solutions (Shrimp IMS and anti-virus drug VPX) were developed to prevent commercial-farmed shrimps from bacterias and a specific kind of virus. This pipeline of Shrimp IMS was built by Aqua Bounty in 2005 and then contributed to all of its revenue in 2005.…
