Nephropore Areas Of Sexually Mature Lobster Case Study

The purpose of the experiment was to investigate the physiological effects of epinephrine on the heart rate of the organism called Daphnia magna as well as to calculate the median effective dose. Daphnia magna are arthropods found in pools of freshwater or areas where freshwater meets seawater in Western Europe and the Atlantic Coastline of the United States (Elenbaas, 2013). They are about two to five millimeters in length and have a transparent shell. Their heart is located on the dorsal side of the organism and the gills are on the ventral side. Daphnia magna also has two antennae and six appendages that are used to bring food and oxygen to the organism’s gills and produce movements.

In the essay “Consider the Lobster”, David Foster Wallace communicates his experience in the Main Lobster Festival as a writer for a food magazine called “Gourmet”. In this essay, he explores the impact the festival had on him as he tries to question the morals of eating lobsters. Wallace initially makes it seem as the festival is a place of fun and celebration as he describes the entertainment: concerts, carnival rides, lobster-themed food, lobster-themed clothes, and lobster-themed toys (50). In spite of that, he changes his attitude as he observes that the festival is actually promoting cruelty to animals and holds a long discussion whether or not lobsters can actually feel pain. Through the use of his language and description, Wallace convinces the audience as he claims to persuade the reader to stop eating lobsters, but he doesn’t explicitly say so at any point in the essay.

Do you know that Maine is famous for lobsters because it harvests the majority of lobsters in the United States? The population reached to 1.336 million people living in the state of Maine. And the total area of Maine is 35,385 square miles, also known as the biggest state with the most land from the original 13 colonies.

Therefore this experiment was to determine that lobsters in various salinities will osmoconform to their environment. In order to test that lobster's osmoconform, we had to extract approximately 1.0 ml hemolymph from their hemocyannin on the ventral first section of the pre-branchial region. The hemolymph was spun for three minutes in a microcentrifuge and the serum was then tested on an osmometer, which determined the osmolarity of the hemolymph. The results substantiated the hypothesis, in that, lobsters internal osmoles fluctuate with the salinity of the external environment. The two lobsters in the low salinity tank had the lowest osmolarity 0.746 osmoles; the two lobsters in the normal salinity had 0.873 osmoles. The last tank with the highest salinity had the lobsters with the highest osmolarity at 1.445 osmoles. Therefore our data suggests that lobster's osmoconform, with respect to the salinity of their environment by readjusting their intracellular solute concentration to prevent swelling or dehydration because the osmolarity of their hemolymph dictates that of the environment.

Individual Daphnia magna are transferred to a microscopic slide using a pipette. The Daphnia was moving freely in a drop of H2O on the slide. For the control, the heart rate of D. magna is observed for 15 seconds

Warren's Lobster House is located on the southern tip of Maine's coast and serves the freshest seafood, lobster and fish. The family-friendly restaurant also has chicken, steak and other seafood available. Warren's Lobster House is a destination restaurant perched on top of wood pilings above the waters of the Piscataqua River. It's located on US 1 and has been open since 1940.

The Callinectes sapidus also known commonly as the Maryland Blue Crab, is a crustacean found in the Chesapeake Bay. The blue crab is found in aquatic environments, most often in estuaries. It characterized by it’s blue claws. The blue crabs undergo a life cycle of: zoeae, megalop, juvenile, and adulthood. The blue crab’s hard shells serve as a protective barrier for external dangers. The Callinectes sapidus comes from the order of Decapods, whereby it’s carapace has now evolved to be better suited for swimming. Of interest is the blue crab’s mating

Imagine that a huge wave crashes down on you. Then it drags you back into the ocean. On your way you pass by an animal that is clinging on for dear life. In order to survive in these harsh conditions, animals need adaptations. An ecosystem is a biological community of interacting organisms and their physical environment. The California Spiny Lobster lives in the neritic e zone which is in between 200 meters and 0 meters. It is located on the continental shelf. They like living in coral reefs and the ocean ground. In order to survive in the neritic zone with predators, sea floor hiders, and other environmental threats, animals need adaptations.

If long lines deter you, and fresh quality seafood doesn’t seem to peek your interest, then this place isn’t for you. But if you can muster up the strength to manage that, then Red Lobster is definitely the place to be. By the time the doors open, customers are ready to enjoy great seafood and even better customer since 1968. I made my way up to my local Red Lobster recently to blissfully indulge myself with their endless shrimp dinner for only $16.99. For top of the line quality with a decently low price, this place really seems to harbor in seafood-lovers

Geographic location: Purple sea urchins are found on the Pacific coastline from Alaska to Cedros Island, Mexico, and from Vancouver Island to Isla Cedra, Baja California.

In 2015, 82,700 tons of Canadian lobster was exported, generating $2.03 billion in revenue. With the current growing need for low production costs and high efficiency, the industry is faced with a number of challenges, including maintenance of high-quality standards and assurance of food safety. This has become crucial in regards to grading for different markets. Businesses require efficient, low-cost, and non-invasive quality and safety inspection technologies to enable them to satisfy different markets' needs, to expand market share.

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.

After 3 days in the diluted seawater the crab’s haemolymph Sodium levels were significantly lower (p<0.001) than the crabs stored in full strength seawater as seen in figure 3. There was no significant difference between the mean haemolymph Sodium values of the three dilutions at 75%, 50% and 25%.

Two crab species, Plagusia and Cyclograpsus, were collected from a local estuary in the littoral and deep water zone for osmoregulation studies. To examine differences in osmoregulatory mechanisms among the species, haemolymph of the specimens was extracted once they were acclimated to varying concentrations of seawater. Using the comparative melting-point, capillary tubes were filled with small samples of seawater and blood then frozen and melted in a -15˚C ethanol bath. The melting time of each was observed thereafter. Subject’s time range fell over 17 minutes of which the majority of the most salinated samples melted
