Marbled Crayfish Research Paper

Students observe and record some of the structures of a crustacean, the crayfish, and compare it to other organisms. They establish a feeding and maintenance schedule for the organisms. Students investigate crayfish behavior and map where the crayfish spend time within their habitat. Through readings, organism cards, and a video, students learn about adaptations of organisms in different environments. Students engage in an outdoor simulation activity to explore food chains.

Crawfish are delicious crustaceans that closely resemble lobsters. Many people consider crawfish to be as delicious as lobsters, which is why these crustaceans are harvested all over the world. In the U.S., crawfish are closely associated with the haute cuisine and culture of Louisiana. In fact, crawfish are the official crustacean of the state. I normally prefer to harvest or purchase crawfish on the day I intend to cook them. However, many people prefer to purchase and eat them later but do not know how to keep crawfish alive in a sack or container for several days before finally preparing and eating them. Fortunately, I will provide you with some tips on how I keep my crawfish fresh and healthy

It’s a beautiful day at the beach, the sun is shining down on you as you float and drift on top of the waves. As you lay there without a care in the world, you are suddenly interrupted by a massive swarm of jellyfish; also known as a bloom. Not only does this send you into sudden terror, it also causes a much bigger threat to the ecosystem below you. The excessive growth of jellyfish swarm drastically lowers the population of fish eggs in the ecosystem. Because of this, fishermen lose millions of dollars. People in local communities are figuring out ways to solve this mass production.

The removal method of Ringed Crayfish data collection was over a sample site area of 50m2 at Pearson Creek, a stream, containing a density of 5.18 crayfish/m2. The sample site was collected in 5m in width by 10m in height with wet, rocky, and grassy conditions. The data collection incorporated five different samples of the number of crayfish removed from the stream each time (Figure 1). Sample one caught 53 Ringed Crayfish with 0 crayfish caught prior. Sample two caught 37 Ringed Crayfish with 53 crayfish caught prior. Sample three caught 42 Ringed Crayfish with 90 crayfish caught prior. Sample four caught 26 Ringed Crayfish with 132 crayfish caught prior. Sample five caught 18 Ringed Crayfish with 158 crayfish caught prior. What was caught in the previous sample was added into the total amount of crayfish caught prior. A negative linear relationship is displayed by data collected in Figure

An entire new world, different from our own exists beneath the surface of our oceans. This life is full of color, shapes, sizes, wonder, and even darkness. Much of this life has yet to be explored but we still know that beneath the waves exist the most beautiful creatures and the most bizarre. Magical areas such as the coral reef and mysterious areas such as the depths of the ocean are homes to over 700,000 species that live in the ocean. This includes the eighty percent of the ocean that has yet to be explored. Even though there may be separate oceans on this planet, they are still interconnected by a body of salt water. No area of the ocean is the same, which brings us to the wonderful fact that so many different species are able to flourish

It was interesting to read that the hypothesis provided by the scientists turned out to be opposite of what happened to Valley Creek. The macroinvertebrates were already living in a low quality creek full of pollution, so I would have also expected their population to decrease after introducing a predator to their environment. The crayfish reminded me of the keystone species sea stars, that I learned about through a lecture on communities and ecosystems. The study conducted on crayfish was similar to a study conducted on sea stars, except they were removed from coastlines instead of being added to see the effect they had. The sea stars were believed to have a negative effect on the coastlines since they preyed on mussels, but it turned out

The first time I felt the recoil of a shotgun coincide with the simultaneous drop and flop of a turkey I knew I was hooked. This was all the way back in the fall of 2005 when I shot my very first turkey alongside my father. That day started an addiction that has since intensified and spread to not only turkeys but almost all of Missouri's highly sought after species. Hunting, conservation, and the great outdoors have always been embedded in the hearts of my family. I am no different and plan to dedicate my life to Missouri’s wildlife the same way they have.

The objective of this project was to cook, and serve lobster utilizing a method, which was given, to prepare the lobster as well as a recipe for the lobster. In addition to this we also needed to create rice pilaf, asparagus, and a vinaigrette salad using the various ingredients provided to us. This project is supposed to give us our first glimpse into implementing our newly found skills from Culinary class into our cooking lifestyle at home.

Item or food picked: American Lobster (Homarus americanus) The Lobster is one of the most valuable seafood exports around the world. With a reported value of $ 1 billion worth of exports and a general upward trend of desire (See figure 1), the lobster might be one of the most interesting foods in the market [1]. In addition to being one of my favourite foods, the reason why I chose to talk about lobster is because it is one of those foods that remind me of my childhood, as I spend some of my younger years living in Maine. This animal that is only found in the Atlantic cost of North America, with its main exporters being Maine, Nova Scotia and New Brunswick.

The most terrifying creature is a clown mixed with a lobster. Clowns are scary enough but a clown with six arms like a lobster is really scary. If a clown had six arms with claws it would chase you in a haunted house with six air horns, and that’s scary. This clown would be like the clown from “IT”. What if you walk into a carnival and saw a six armed lobster clown I would run away.

The killer shrimp is a combination of shrimp and a pray mantis. They are dangerous and have incredible abilities, having an incredible strength compared to their size. They got powerful appendages that can be used for hunting or for self protection. The mantis shrimp is a territorial animal, and the individuals of that specie usually fight for shelters. Their appendages work like hammers, what provides a strong impact force.

It is also prey to other animals, such as horse conch, grouper, sea turtles, cobia,

The purpose of the experiment is to observe    and analyze the subject. What should be learned is, what are the most important parts for the crayfish to be able to survive. You should also learn what organs help the crayfish survive out in the ocean.

Signal crayfish has become widespread through Europe in the last century due to human activities. Signal crayfish poses a threat for the endemic noble crayfish in most of the European countries as a vector of the crayfish plague and competition. As an invasive species, signal crayfish can alter the energy flow of the ecosystem through the food webs since, as omnivorous, it can feed from several trophic level, modifying the ecosystem assemblage. On the other hand, the noble crayfish is endangered due to several factors like water pollution, ecosystem alteration and crayfish plague; consequently, their restauration may be not possible. Therefore, this review aims to compile the effects of the invasive signal crayfish in European freshwater

Native to North Africa and the Middle East, the Blue Tilapia or, just Tilapia is an invasive species in the southeastern United States in places such as Florida, Alabama, and Texas. You will find Tilapia in just about any fresh water source that has a relatively warm temperature. Some Talipia have been found living in cooler water, and some have even been recorded living on the coastlines in saltwater. Tilapias have the ability to rapidly reproduce and are often seen guarding their eggs which lead to a higher rate of births. Tilapia compete with other fish for the same type of food and nesting grounds. It is believed that Tilapia have caused a decline in other fish species due to there rapid reproduction and competitive eating habits.
