throughout the experimental period. Table 1 show that the highest mortality rate occurred in Nile tilapia fish in the S. iniae+ C. albicans infected group (76.19%)‚ followed by those infected with S. iniae alone (61.9%) and then the C. albicans infected group (57.14%). Clinically‚ the S. iniae-infected fish exhibited loss of appetite‚ loss of equilibrium with erratic movement‚ swam near to the surface of water‚ detachment of scales‚ hemorrhages on the different parts of body surface‚ slight abdominal dropsy

Ecology Essay Water makes up 75% of your body and is absolutely necessary for living. But do we know what we are drinking when we drink bottled‚ Recycled‚ and tap water? You might think it really does not matter‚ i mean they are all the same clean water right? Well‚ according to Rebecca Ephriham water that individuals and our families drink could contain deadly toxins‚ and can even cause cancer and other life threatening diseases. Some water is much cleaner than others and a much better choice for

Introduction Paragraph The question that’s being investigated is what is the water quality of the U-high creek based on the macroinvertebrates found in the creek. Water quality can be measured in various ways including oxygen levels‚ pH‚ nitrogen and phosphorus levels. Dissolved oxygen is when oxygen molecules mix with water molecules. It is important because water gets into oxygen from the surrounding air.The pH scale is used to measure the relative acidity of solutions and phosphorus is a chemical

Nitrate on Pond Water By Claudia Phillips September 6‚ 2014 Block Two INTRODUCTION This lab was designed to study and observe the effects of phosphate and nitrate applied to pond water (1). Phosphorous‚ commonly used in fertilizers‚ is a necessary and vital element for life but can enhance the effects of eutrophication (the over-enrichment of nutrients in water) (2). Nitrate is a common source of food for most algae‚ but too much can make living conditions in water harsh (3). They are

There are two visible features of contaminated water; colour and smell. Contaminated water usually has unusual smell and coloured. Invisible factors affecting water quality are sources of water. For instance; tap water

Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water or 30% sucrose. I thought this because I thought that there would be more of a substance change in 60% sucrose. Section 3: Methods First get 3 pieces of the same

The question being looked into is “What is the water quality of the U-High creek‚ based on invertebrates found in the U-High Creek? “Dissolved oxygen is oxygen mixed with water. The range to measure how much dissolved oxygen is in a solution is 1-14 milligrams per liter. This is important because fish and other organisms in the ocean breathe off of dissolved oxygen. Phosphorus is used to measure the relative acidity of solutions such as water. The range for pH is measured in 0-14 scale. 0-6 is unhealthy
