CAUTIONARY STATEMENTS NOTE: This set may include chemicals that could be harmful if misused. Read all cautionary statements in this Manual. [. . . ] Crabs and lobsters are perhaps the most wellknown crustaceans. Brine shrimp are the major part of the diet of many sea creatures. The word brine means water containing noticeable amounts of salt. Your microscope kit comes supplied with sea salt , brine shrimp eggs (G, Fig. The brine shrimp eggs included with this set are dried and will remain alive for up to five years if stored in a cool, dry place. Perform the following procedure to hatch the brine shrimp eggs: 1. To hatch the eggs, first prepare a brine solution. Pour the entire contents of the vial containing the sea salt (G, Fig. Add the brine shrimp eggs into the solution. Allow the solution to stand at room temperature (70° - 80°F or 21° - 26°C) for 24 to 48 hours and the eggs will hatch into nauplius larvae (this is the first stage of development after leaving the eggs). Place some of the larvae into one of the compartments of the shrimp hatchery (M, Fig. Place some fresh brine solution in another compartment. Add a small amount of yeast to this new solution. 1), transfer some of the larvae into this compartment as well. The yeast will serve as food and produce oxygen for the lar- 9 vae as they develop into maturity. Without food and oxygen, the shrimp cannot develop and will die. Mature brine shrimp are known as Artemia Salina. Note: Using an eyedropper with just the right pressure to get a desired amount of liquid onto a slide can be harder than it looks. Take out a clean slide and practice squeezing a drop of water onto the slide until you feel comfortable that you can control the size of the drop that you're squeezing out. Observe the life cycle of the shrimp as they grow: the dried eggs, the hatching eggs, the developing larvae, and finally, the mature shrimp. The mature shrimp may be fed to fish in an aquarium if you so wish. However, first remove the shrimp from the brine solution and place them into fresh water. [. . . ] Using the tweezers, remove the piece from the stain. Hold it over the waste cup and flush it with clean water from your eyedropper. To save your slide, follow the procedure described previously. Life Under Glass Fill a wide mouth jar with fresh water. [. . . ]
