Brine Shrimp Lab Report

If hatching viability is affected by the amount of motor oil in the environment of the brine shrimp eggs, then when the amount of motor oil is increased the hatching viability will decrease.

Brine Shrimp are a micro-crustacean that is found mostly in inland saltwater bodies, however, the salinity levels that they live in vary greatly. The conditions that they require can be made at home as the eggs (cysts) of the shrimp are dry, hard shells that can withstand drought and go without water for up to 50 years. This study presents the results of 3 different salinity levelled environments to the Brine shrimp in order to discover a salinity level that produces the most successful hatching rate. By filling 3 Petri dishes with 20mL’s of purified water, each dish contained varying sodium chloride amounts from 15ppt, 25ppt, and

Brine Shrimp start out at something called cysts which you can buy all over the world and it takes only one night in water for them to hatch into the Brine Shrimp. At a maximum length, Brine Shrimp only get up to a little over 1 centimeter which is perfect size for fish around 10 centimeters. I thought that growing the Brine Shrimp was one of the most interesting things that I did while I was there.

Behavior of Brine Shrimp in Habitat Selection Introduction: This experiment was developed primarily to find the optimal or preferred living conditions of adult brine shrimp. In this lab 3 variables were tested in different degrees to determine which the shrimp prefer. The different variables were light, ph, and temperature. From outside resources I have found that brine shrimp can survive in temperatures ranging from 4° Celsius to 40° Celsius with an optimal temperature of 20°-25°. So I hope to reinforce this research by testing its validity in the lab. From another outside source brine shrimp display positive photo taxis, which means that they are attracted to light. And finally from my last outside source I have found information that

As previously mentioned Blue Crabs are highly susceptible to changes in environmental conditions. As an example, larvae require high salinity waters. Larvae require salinity of at least 20 ppt and below that threshold, there is poor likelihood of survival ability.

The aim of this lab is to determine if the Seven River oyster is suitable for oyster restoration. During this lab we learned that Salinity affects the oysters if it is more than 10-13ppt. We also have knowledge that there is a parasite (the protozoan, Haplospordium nelson) that causes the disease MSX in oysters (Readel, 2000). Moreover, at the lab we knew that MSX bacteria will grow if salinity is above 15 ppt that will cause the oysters to die. The oysters can be affected by MSX if the salinity is above 15 ppt (Readel, 2000). Furthermore, Oysters are also used to filter the water of the river. Also, we learned that the range of tolerance of salinity for oysters is 10-27

The Mantis Shrimp is a mid sized crustacean that can grow up to 3 to 18 centimeters in size. It is known for its bright colors of blues reds and greens, they are primarily green on the belly it has bright reds and oranges on its legs and spots on its framework, while a bright blue is on its eyes. Females are almost always more orange and red than males which are in more various colors. Their spears or clubs are what define this species, these clubs are what mantis shrimp use as a deadly weapon, they can accelerate these clubs at the speed of a bullet from a .22 caliber rifle. Their eyes can see 12 different color waves the most of any animal discovered on earth. They make their homes by burrowing into the ground or finding old burrows left

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.

In the literature review, we stated that others have also shown that the higher the salinity, the higher chances of the brine shrimp surviving in the saltwater. We were uncertain about the brine shrimp of not having high survival rates in lower salinities, due to the brine shrimp species mainly don’t live in high salinity areas.

The last things that have some effect on the shrimp habitat is the weather. For the last two to three years we have been in a drought. This can also cause the stream or creek to been dry up or low on water. When the stream dry up can cause the whole habitat to an end. Also when we in a drought with little to no rain the shrimp can’t survive due to the water is not moving from other end of the stream. The water is not moving then the shrimp doesn’t have a lot of food source to eat.

The results from the experiment have shown that an increase in sodium chloride solution increases the rate of osmosis and diffusion until the percentage reaches an amount that is near the concentration of solutes inside the eggs membrane.

Özogul and Özogul (2006) found that putresine concentration increased during the storage period of sardine held in air, VP and MAP, reaching maximum levels of 12.2 mg/100 g at 12 days, 7.59 mg/100 g at 10 days and 5.83 mg/100 g at 10 days, respectively, whereas cadaverine levels reached of maximum level of 10.0 mg/100 g for fish stored in air for 15 days, 5.73 mg/100 g in VP for 10 days and 5.21 mg/100 g in MAP for 10 days of

1.3.1. Deproteinization: Shrimp shell waste will be treated with 4% NaOH at room temperature for 24 hours. The alkali will be drained from the shells and washed with distilled water repeatedly till pH dropped to neutral.

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%.

Shrimps remain to be the largest single product in value terms accounting about 15 % of the internationally traded fisheries products in 2012. Moreover, shrimps are primarily produced in developing countries, and much of this production progressively expands in the international trade. As the economic conditions develop in these countries, growing demand leads to high domestic consumption leading to fewer exports. Such high demand and the subsequent overexploitation are negatively impacting the standing stocks of shrimp which fall below the healthy standard levels. This requires regular monitoring, assessment and management of each species to keep tracking of the effects of such
