A. What was your hypothesis for this experiment? I believe 60 grams of sea salt will be the best for the hatching of brine shrimp eggs.

B. Based upon your observations, what was the corresponding salinity of the solutions in each of the five vials? Please explain your answer.

1) 0 2) 60 3) 90 4) 120 5) 30

Because brine shrimp have succeeded in living in highly saline bodies of water, I believe that the vials with more shrimp that hatched had the higher salinities, and the vials with no shrimp hatching had the lowest salinity levels.

B. Please discuss why it was critical to this experiment that an equal number of brine shrimp eggs were added to each vial. It was critical to add an equal number of brine shrimp to each vial to keep the experiment’s quantity variable constant. Otherwise, data collected from each of the different vials could not be accurately...

...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......

Morton Salt

...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......

...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......

Two Kinds of Sex Pheromones in Lysmata Shrimps

...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,......

Agri's 112.9 million metric ton fish catch. The following year, it was 13th among the 51 top fish producing countries with a total fish production of 1.8 million tons. In 2001, the country's fish yield further increased by 166,101 metric tons. There are different kinds of fishes and other aqua creatures like tilapia, tuna, mackerel, talilong, shrimps, seashells and most commonly the country’s national, the milkfish or bangus. Milkfish (Chanos chanos forskal) of bangus as locally comprises the bulk of aquaculture production in the Philippines. Its farming is regarded as the backbone of the Philippine aquaculture. They are hardy and fast growing, and can be raised in fresh and brackish water ponds, pens and cages. Being one of the dominant farmed-species for aquaculture, milkfish farming is geared towards high-density culture system, due to little or no prospect of expanding the brackish water farming area; support capture fisheries production which is on its continuing decline; and the rise and fall shrimps industry, due to disease problem. The industry’s remarkable progress can be attributed to the growing number of experienced shrimp farmers that are shifting to intensive milkfish culture. Various modifications in bangus culture have been developed towards attaining high bangus production. This manual aims to guide our fish farmers with systematized and modified milkfish farming practices. Milkfish production represents one of the main sectors of the nation's fishery......

Financial Business Prospectus

...Assessment - Operating Plan - Financial Plan - Executive summary The new business venture I planned to invest would be a Shrimp Farmer. The market demands of organic food have increased the global production of freshwater shrimp farming. Shrimp has become the most popular seafood in the United States. On the other hand, consumers are becoming more conscious and concerned about the environment damage. Many shrimp farmers often use antibiotics and hormones to increase the shrimp production. The methods used before to meet the shrimp’s demands have dramatically damage environment. Now, many advances in researcher found new methods and technology that have changed the scenario. Business Description Carrillo’s Shrimp Farm would be placed in the Desert of Imperial Valley to combine the effects of the hot sun with the qualities of deep pumping well water allowing a faster growth. The shrimp would be raise in a pond with significantly depth water having as a mission a fresh, healthy, and free hormone shrimp. Since the well water rich in mineral would be drawn from deep pumping, it would carefully monitor for pollution, contaminants, and pathogens. Neither pesticides nor chemicals would be added to care about health negative effect such as neurological damage and E. coli. Before introducing population to the ponds, the baby shrimp should be properly acclimated to reduce stress and death. Another factor that prevent unnecessary stress is a PH...
