...schmichael Brine Shrimp lab 2013 9/10/13 Introduction Artemia salina or (Brine Shrimp) belong to the Anthropoda phylum. Brine Shrimp are found in a variety of different habitats, ranging from temporary ponds to estuaries, lakes and rivers. A Brine Shrimp’s ability to inhabit various environments can be attributed to their tolerance of a range of salinities. Brine Shrimp have been found to survive in salinities from 0% to 15%. When hatching Brine Shrimp the highest number of eggs will hatch at a salinity of 7.5%. The ability to adapt to new environments gives Brine Shrimp a distinct advantage among their aquatic community, and allows them to successfully reproduce and survive within their environment. Materials and Methods In determining the optimal salinity for hatching brine shrimp eggs, seven samples were made with salinities ranging from 0%, 3.5%, 5%, 7.5%, 10%, 12.5%, and 15%. Four trials were performed for each of the seven samples. The room temperature and the water used were both at 72°F. The salt used to create the samples was supplied by Carolina Biological Supply Company. The seven ranging salinities were prepared in 100 mL samples. Seven masses of salt were measured on a scale (0g, 3.5g, 5g, 7.5g, 10g, 12.5g, and 15g) and were corresponded to a beaker filled with 100 mL of distilled water. For each sample, four trials were replicated by filling 30 mL plastic vials with 25 mL of solution. 2400 cysts (one...

...marine environment to acidic neutral or basic, affect the lifespan of brine shrimp? Hypothesis: If I adjust the pH of a brine shrimp environment, then the environment with the lowest pH will have the shortest lifespan. Research: Brine shrimp are fresh water invertebrates. Adult male shrimp grow up to 0.3-0.4 inches long, while females grow up to 0.4-0.5 inches. They are capable of surviving in fresh and slightly brackish water. Scientist believe that the shrimp were originally freshwater sea life that adapted to salt. Brine shrimp shrimp are commonly found in Great Salt Lake. They play a huge part in the migration of bird because without them as a food source, they migration wouldn't...

...suggested that the brine shrimp’s preference for green light is due to their food sources being predominantly green in colour. However brine shrimp are non-selective filter feeders who have no preference in what food they consume as they only consume what food is available to them at the time. This raises the question as to why the brine shrimp have an apparent preferred wavelength of light in this set of results. It could be assumed that the brine shrimp were raised in an environment where an area with a similar light colour to the green light used in the experiment contained more mates, was a safer environment and had a greater resource of food. As the brine shrimp move towards the light they would be more visible to predators in their...

...Biology Period 1 The Effect of Varying Light Intensities on the Location Preference of Brine Shrimp Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will prefer a chamber with significant light intensity because they need light in order to hatch and develop. Null Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will not have a preference. Procedure: The brine shrimp were placed in the long tube choice chamber. Four quadrants were labeled and covered with varying materials to block out a certain amount of light. Quadrant 1 was in full light with 62 FC, quadrant 2 was covered in a material that allowed 29 FC of light, quadrant 3 was exposed to 12 FC of light, and quadrant 4 only had 1 FC, or almost no light exposed. Brine shrimp were introduced to the choice chamber with a 60 mL syringe and then observed for several minutes before recording results. Results:...

...The Effect of Calcium on Hatching Brine Shrimp Eggs science fair project will investigate how the addition of various amounts of calcium to brine shrimp eggs will affect their hatch rates. I was drawn to this area because I have an interest in how several outside factors can affect the nature of a process. My hypothesis for this lab is that the larger amount of calcium added into a petri dish will result with a faster hatching rate due to the extra nutrients. The independent variable of this lab is the concentrations of calcium, while the dependent variable is the brine shrimp eggs hatch rate. The constant is petri dish A that will have no calcium added. I plan on measuring this rate through observing the individual petri dishes every twelve hours under a magnifying glass and counting the number of eggs that hatch. The science of this lab can be traced back to the background...

...10-1. In condition two, denoted B, we created a 10-3 concentration of algae. During the collecting of the brine shrimp, they had yet to hatch and we found it profoundly difficulty to collect individual cysts. Due to this, we estimated the number of cysts to be placed in each jar. We first diluted the sample of cysts we were given and collected a loop full and added it to each jar. In between each inoculation, we shook the plate containing the cysts and water to evenly distribute them. To estimate the number of cysts added to each jar, we then collected a loop full and counted the number...

...Lobster is one of the commodities that Indonesia export fisheries worth selling high. Lobster exports by 2014 reach 3,427 tons valued at US $42.8 million (Ditjen P2HP 2015). The value of selling lobster is affected by type, size, and condition or completeness of her body. In the morphology of almost the entire body of the lobster is covered by a hard and sharp spines. Palabuhanratu is one of the centers of the lobster fishery in the South of West Java. Gill nets blo'on nets/Basic is a tool commonly used to catch Palabuhanratu fishing to catch lobsters. One of the factors that affect the efficiency and the capture of fish on the net is a big base of the gills hang-in ratio used. The higher the HR which is used then the amount of material (the nets) Unity long more and more so that the net is getting slack. Hang-in ratio (HR) commonly used fishing nets the gills of Palabuhanratu basis of 52%. Already the use of HR are efficient to catch lobster? While the body of the lobster itself is filled with thorns. The presence of spines that provide great opportunities for lobster terpuntal on the net and the more difficult it is released when having HR high. Difficulty releasing the lobster terpuntal on the NET allows patahnya lobster body parts. During this time if the fishermen get a very terpuntal lobster catches in the net, they release the lobster by means of cutting the net to preserve the quality of the lobster (no damaged parts of the body). The cutting of the nets constantly can...

...Case Study : Morton Salt 1. Briefly describe salt production, from brine production to finished round cans. Salt is obtained by introducing water into salt caverns which in turn dissolves the salt deposits within the caverns, allowing the salt solution (brine) to be brought to the surface for further processing. The brine is boiled in order to remove most of the liquid, resulting in salt crystal deposits. The salt crystal deposits are then further dried to remove all residual moisture to produce the final product; salt. The finished product is stored within a silo awaiting production. The round cans used for packaging salt are produced on-site. The cans are produced by gluing two sheets of chip board and rolled into a continuous tube. The tube is then cut into long sections and then cut again into can-size pieces. The finished pieces are moved on conveyor to where the various parts can be assembled into cans and glued. Once the cans are formed, they are filled with salt and the pour spout is added to the can. Once completed, the finished cans containing salt are loaded onto pallets and placed into inventory awaiting shipping to distributors. 2. Briefly describe quality assurance efforts in round can production. Quality is checked primarily by visual inspection including verifying the assembly was done correctly, checking the filled cans for correct weight, inspecting cans to ensure labels are correctly aligned, and checking to see whether metal pour spouts are correctly...

...he term shrimp is used to refer to some decapod crustaceans, although the exact animals covered can vary. Used broadly, it may cover any of the groups with elongated bodies and a primarily swimming mode of locomotion – chiefly Caridea and Dendrobranchiata. In some fields, however, the term is used more narrowly, and may be restricted to Caridea, to smaller species of either group, or to only the marine species. Under the broader definition, shrimp may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long narrow muscular tails (abdomens), long whiskers (antennae) and slender legs.[1] They swim forward by paddling with swimmerets on the underside of their abdomens. Crabs and lobsters have strong walking legs, whereas shrimp have thin fragile legs which they use primarily for perching.[2] Shrimp are widespread and abundant. They can be found feeding near the seafloor on most coasts and estuaries, as well as in rivers and lakes. To escape predators, some species flip off the seafloor and dive into the sediment.[2] They usually live from one to seven years.[3] Shrimp are often solitary, though they can form large schools during the spawning season.[2][4] There are thousands of species, and usually there is a species adapted to any particular habitat. Any small crustacean which resembles a shrimp tends to be called one.[5] They play important roles in the food chain and are important food sources for larger animals from fish to whales. The muscular tails...

It is popular on a stick dipped in hot chili powder and salt or also as a main ingredient in fresh fruit combinations. “In Central America, mango is either eaten green mixed with salt, vinegar, black pepper and hot sauce, or ripe in various forms”(Fresh mangos, 2011). Toasted and ground pumpkin seed with lime and salt are used in their country when eating green mangoes. Some people also add soy sauce or chili sauce. Pieces of mango can be mashed and used as a topping on ice cream or blended with milk and ice as milkshakes.

...Sex pheromones in Lysmata shrimps Rui Yang BIO4995 Undergraduate Research Advisor: Dr. Junda Lin July 30, 2010 Introduction Many crustaceans species, such as crabs (Ryan 1966; Gleeson 1980; Seifert 1982; Hardege et al. 2002; Kamio et al. 2002), lobsters (Atema 1984 for a review), and crayfish (Ameyaw-Akumn and Hazlett 1975; Tierney et al. 1984), copulate with the females using chemical compounds as sex attractants. Pheromones as a kind of chemical signals are widespread in aquatic species. To communicate and mate, sex pheromones that emitted by male or female become the most important chemical messages and are also used in mate choice. Sex pheromones are classified two types: distance pheromones and contact pheromones. As a kind of water-borne (aquatic species) or volatile (terrestrial species) chemical, distance pheromones can take effect within a certain range in water or in air Chang et al. 2007, Lim and Greenfield 2008). Kamio et al. (2002) found that post-molt females can release a water-borne pheromone, which is different from pre-molt females. Unlike distance pheromones, contact pheromones are insoluble and coat the female’s body (Kamiguchi 1972, Bauer 1979, Borowsky 1991, Zhang and Lin 2006). In many animals, pheromones are detected by specialized receptor organs, such as vomeronasal systems of vertebrates (Halpern and Martinez-Marcos 2003). But crustaceans sense chemicals through an organ called cuticular sensilla. Antennules, as the first part of antennae, have...
