Temperature had a direct effect on oxygen consumption of crayfish, Orconectes propinquus. Crayfish acclimated to warm temperature (20 to 25 C) had a mean mass of 8.25g +/- 1.05. Crayfish acclimated to cold temperature (3 to 5 C) had a mean mass of 10.61g +/- 0.77. Oxygen consumption rates of 30-60 minute treatments were used and there was no significant difference between the two different treatments (t=0.48, df=58, P=0.70). The data from 0-30 minutes were not used because the crayfish were disrupted by transportation and the data were not normally distributed. The Q10 value was 1.05, representing that there was full compensation for oxygen consumption for the crayfish at two different acclimated temperatures. The oxygen consumption of crayfish was not affected significantly by two different temperatures (Figure 1).

The barnacles were tested using a small cup filled with water which has a small rock with barnacles on it. Before the experiment was conducted, the barnacles were fed food. The change in cirri beats over one minute was determined. The average decrease of cirri beats per minute was 12.6. Although the manipulated trial was inconsistent, it is still logical to conclude that the

Daphnia, or water fleas (named after the jerky, jumping way in which they move), are tiny planktonic crustaceans measuring around 1mm in length. They live in freshwater lakes and ponds, filter feeding on green algae, bacteria, yeast and phytoplankton, before being the prey of small fish such as sticklebacks and minnows. As a primary consumer, Daphnia provide an important link in the human food chain; increasingly larger fish such as salmon are dependant on their numbers. In terms of their nutritional values, adult Daphnia have a protein content of approximately 50% dry mass and a fat content of 20-27%. (Clare) (Background information on Daphnia)

Today, teens face many struggles which include making decisions on, medical, social as well as academic matters. These are only a few decisions that teens need to face. Achieve3000’s article “New Heart, New Life” takes the reader on a journey of 16 year old Courtney Mescall who was faced with the important decision of whether or not to get a heart transplant. At first, Mescall refused the surgery thinking of her past medical history. After evaluating her options she finally agreed to have the medical procedure done. She tells readers how thankful she was that she did have the surgery done and how happy she is that she is alive and healthy. When looking at Mescall´s story one can easily see how she had help from her mother to guide her into

fresh-tasting fluid could be sucked out not only from the eyes of larger fish but also from their

For water dwelling animals, those that do not possess fins and scales are considered non-kosher. That means, animals such as crabs, bivalves, lobsters, and mollusks (octopus, squid) are considered to be non-kosher. With regards to birds, they are considered non-kosher if they are birds of prey or if they feed on carrion. Reptiles are not allowed for

Two of the glow sticks will be blue whereas the remaining two will be red. However, in order to test the effect of bright colors against dull colors, I will be wrapping one blue and one red glow stick in wax paper in order to make their colors dull, leaving the other two unwrapped to give off a brighter color. I will also use two male B. splendens, both of which will be contained in their own, two gallon, plastic aquarium filled with water. To monitor the temperature of the water inside the aquariums, a thermometer will be placed in each. One of the fish, inside its aquarium, will be the experimental group while the other fish will be the control group. The experimental group will be exposed to only one glow stick at a time, whereas the glow sticks will be absent from inside the control group’s aquarium at all times during the experiment. Cardboard will also be required, as it will act as a barrier between the two aquariums. This barrier will prevent any light from the experimental group being visible to the control group. In addition, the cardboard will keep both fish visually isolated from each other, which will, in turn, prevent the two fish from being aggressive towards each other and affecting the data. Finally, I will use a timer to keep track of the amount of time that the experimental fish was exposed to each glow

Some good fish to keep with Texas Cichlids include Plecos, Oscars and other bigger cichlids ("Texas Cichlid"). Not all species are aggressive though, some can do well with other fish (Berg, William). The personality traits of the fish can evolve over time and for some, as they grow older, they can’t be around other fish and should be kept alone (Berg, William). They eat both meat and vegetation and will eat just about anything (Sharpe, William).

The photos show that zooplanktons, rotifer, cladoceranr and copepod, could take in three types of MPs (0.1,1,9.9 µm) overtly. But all organisms no MPs in vivo under 101 µm diameter exposure surroundings were observed by fluorescence microscope, so there were not pictures printed here. Many freshwater and marine species such as annelids, crustaceans, ostracods and gastropods were reported that could uptake MPs(Imhof et al., 2013b; Setala et al., 2014). In the present study, the uptake of microspheres after 24h exposure in three kinds of zooplankton, rotifers, cladocerans and copepods, were captured by the fluorescence microscope. The observations displayed that rotifer gained MPs though test environment with remnant digestive production remaining in mastax, cloaca, (Fig.1 A, D, G), while cladocerans absorbed MPs by filter feeding so that MPs were discovered explicitly in their filter-feeding and intestinal tract (Fig.1 B, E, H), copepod also can procure three kinds of diameter MPs in a high concentration polystyrene microspheres condition, then persisted in digestive tract (Fig.1 C, F, I). Fig.1 suggests samples from wild fresh water had the capability of gaining fluorescence particles under the surroundings with MPs. They can uptake three types of microspheres apparently, 0.1,1,9.9 µm, out of 101 µm diameter. Early researches focused on selection at plastic sizes

Daphnia are used to test water toxicity, they are a vital part of fresh water ecosystems. They are a food source for smaller fish and invertebrates and considered to be a consumer of algae and bacteria (Elbert, 2005). These small crustaceans range in size from 2-5mm long and are commonly referred to as water fleas. Daphnia belong to the group called Daphniidae, which is a relative of freshwater shrimp. It is easy to see the internal organs of daphnia because of a transparent taco shell like carapace. A carapace is the hard outer part of a shell or covering. A daphnia’s life span can range between 1-56 days. (Elenbaas, 2013; Clare 2002). The comfortable pH level for daphnia is between 7.2 and 8.5 (Clare, 2002).

9/11: The beta fish was added into the water along with a drop of auto safe water conditioner. Before planting marigolds, cosmos, bachelor buttons, and carrots, another cup of topsoil was poured in. The beta fish was given 3 flakes of food. Each quadrant of the soil received about ¼ of the pipet’s water. It was observed that condensation had occurred in the top part of the bio bottle.

I definitely would have a disappointment if they died. Accordingly, every other day I fed them. Every three days, I changed their salt water ¨pool,¨ or their water tray. Moreover, when they got sand on the floor, I was

If you're reading this article I am guessing you have sparked an interest in the addictive cichlid tank hobby! I am guessing you probably have no idea where to start to make the best healthy successful cichlid tank. That where I come in I have had cichlids for over 3 years, and have had my ups and downs with the hobby due to my little experience when I started the Hobby. Throughout this article I will teaching you how to buy the right size tank to setting up the perfect filter and filtration system using my past experience and research.

This would help to prevent the spread of the infection and also heal the infected fish. Generally, the freshness of the water in the tank cannot be over-emphasized. The Papuan Toby is a fish that loves to be as close as it can to its natural habitat. Due to its aggressive tendencies, it can be a delight to watch their activities in the tank. However, this must not be done to bringing about stress points to their health.

Ciguatera fish poisoning is a diagnosis based upon a group of symptoms the quickly follow the ingestion of the carnivorous fish. You may notice symptoms as early as 15 minutes or as late as 24 hours after ingestion. Usually, symptoms are noticed within 6-12 hours after ingestion. Symptoms increase predominance and in severity over a period of 4-6 hours. This form of poisoning mainly affects major organ systems including the GI, neurologic, and cardiovascular. The toxin may be found in large reef fish, mostly grouper, barracuda, red snapper, amberjack, eel, sea bass, and Spanish mackerel. The area of concern include the Caribbean Sea, Hawaii, and coastal Central
