Starfish And Green Crab Lab Report

In this essay i’m going to tell you about the fiddler crab. Here is one fact the fiddler

The purpose of this lab was to answer the question, “Of the saline solutions of 0%, 0.5%, 1%, 1.5%, and 2% sodium chloride (NaCl), which solution will yield the highest hatching viability for the brine shrimp?” The hypothesis was that the saline solution most precise to the concentration of NaCl in seawater, which is approximately 3.5%, will yield the highest hatching viability. Therefore, the 2% NaCl solution will yield the highest hatching viability.

Horseshoe crabs are an important part of the wetland ecosystem, however they are going extinct. Due to harvesting, pollution, and other animals consuming their offspring their numbers are dwindling. They play an important part in the ecosystem and need to be protected so they do not become extinct. The Delaware bay has decided to protect them for their future uses in medicine and to keep them as an important role in the ecosystem.

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 Effect of Caffeine on Goldfish Metabolism Introduction Metabolism is the sum of all anabolic and catabolic reactions within a living organism. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of respiratory system affects the metabolism. Previous studies have shown that caffeine affects the human respiratory center and occasionally dilates bronchus. It can therefore simulate human respiration and increase the metabolic rate (Haggins et al, 1915).

The null hypothesis for this experiment is that there is no statistically significant relationship between the metabolic rate of goldfish and their exposure to light. The alternative hypothesis is that goldfish exposed to ambient light will exhibit a higher metabolic rate compared to goldfish that are exposed to dark light. Results Overall 86 goldfish (N=43) were used in the experiment. Altogether, 43 trails (2 fish per trial) were conducted in order to track the metabolic rates of the fishes. Differences in metabolic rates (with respect to light exposure) were calculated by measuring the changes of oxygen concentration in the water chambers where the fishes were placed.

I haven't always been keen on reading as I am today. I can’t really remember the reason for my distaste in literature, but I think it mostly came from me just thinking that reading was too difficult or I was just me being a stubborn six year old not wanting to do it, but none the less I was like this for a lot of my earlier years. I was able to read a small amount of text because my parents teaching me, using Doctor Seuss books like Cat and the Hat and One FIsh Two Fish Red Fish Blue FIsh as learning tools to help me become more fluent. I never really understood reading until my stepmom moved in with us. Since my sister and I were still very young

Horseshoe crabs have been on the earth since 30 million years ago which is before the dinosaurs lived. The Delaware Bay has the biggest population of horseshoe crabs in the world. In Delaware, the horseshoe crab population has decreased rapidly which is a problem for the environment. Many shorebirds that migrate, rely on horseshoe crab eggs for food. Also, the biomedical industry depends on horseshoe crabs for the substance, Limulus Amoebocyte Lysate(LAL) that is found in the blood of horseshoe crabs. Finally, fisheries use horseshoe crabs as bait for eels and whelk. Delaware researches and protects horseshoe crabs to benefit the environment and humans.

This history will lead kids and adults to navigate the waves of imagination, on an exciting adventure, which begins on the seabed and culminates with a fight for life between brave goldfish, captured by a fishing net, and his enemy – the terrible Mr. Cat.

The blue crab Callinectes sapidus is a wide-ranging, ecologically and economically important species along the Atlantic and Gulf of Mexico (GMx) coasts of North America. Consequently, its basic biology, life history, population genetics, and demography have been the subjects of numerous studies. For my dissertation research, I propose to focus on two critical areas concerning the ecology and evolution of blue crabs that have broader implications for our understanding of marine organisms with biphasic life cycles. For the first chapter I will investigate the unusual finding of extreme temporal and spatial variation in the genetic composition of settling blue crab larvae along the Texas coast. Since it was reported in 1993, this finding been

The Impact Lionfish is quite dangerous because they damage marine aquatic ecosystems by decimating life on reefs. The way lionfish causes the damage is by eating small fish who keep the reefs healthy. Lionfishes can live a while without eating. While being 3 months or longer that they don’t really have to eat. Which can help them live while unlike the food they eat can’t survive that long without eating.

The researchers focused their study on determining whether cuttlefish adjust their body pattern intensity with reference to artificial and natural substrate intensity under different light conditions of bright light, moderate light, low light, and extremely low light. For each set of experiments, 10 adult Sepia officinalis were confined with an artificial or natural substrate placed the floor and walls of a seawater-filled tank and was left to get accustomed to low light for 20 minutes. After those 20 minutes, a photo was taken using a flash, digital camera. The cuttlefish is then left to adapt in a set light condition with the same substrate for another 20 minutes. Following the 20 minutes, the light is turned off and a flash photo was

The aim of the present study was to test the hypothesis that the invasive red king crab, Paralithodes camtschaticus, may hamper capelin recruitment through egg consumption, by carrying out fieldwork studies (2005, 2006), laboratory experiments (2011), and applying models of consumption. To explore the response of the predator to prey density, crab abundance and capelin egg density were estimated in stratified study areas. An exponential decay model was used to estimate stomach evacuation rates of capelin eggs in red king crab stomachs, and the average evacuation time estimated was 5.38 h at 2.9°C. The average evacuation time was applied to a consumption model where uncertainty in input values was assessed by Monte Carlo simulation. Estimated

The American horseshoe crab (Limulus polyphemus) has persisted largely unaltered for millions of years (Smith et al., 2006), and has ancestors that date back 450 million years ago (Swan, 2005). They belong to the genus Limulaceae, and are an ancient group of aquatic merostome arthropods (Sekiguichi, K., and Shuster J., 2011). Limulus polyphemus inhabits the eastern coast of the United States (Goode and Wahle, n.d., Swan, 2005). It ranges from the Yucatan Peninsula to the Gulf of Mexico (Moore and Perkin, 2007 (Shuster, 1979), about 42 to 19° N (Botton, 2003). Limulus polyphemus are found within estuaries, coastal embayments, and on the inshore continental shelves near the mouths of estuaries, usually in waters that are less than 30 meters
