Salil and Laura who are in biology will be going down to Westlake to buy five local fish (caught in Westlake) and we will determine their health based on the following criteria:
 * What we're doing: **
 * Even though it's a fish, it should not smell "fishy" -- it should smell fresh and clean
 * Touch the fish: It should be firm and not slimy
 * The skin shoudln't present a "rainbow" effect from surface oils. While not a complete fail, if this sign is present, it indicates some age and poor preservation on the fish.
 * If it smells bad, forget it. The scent of amonia is a killer. If the fish is obviously warm to the touch, forget it.
 * If the fish have any "abnormalities"
 * Gills should be closed and not inflamed
 * The scales should be flat and intact
 * The stomach shouldn't be bloated
 * The eyes should be clear, cloudy eyes are not good

If the Westlake passes most of point in the criteria, then the fish can be considered "healthy".


 * Equipment List: **
 * 1) 5 Westlake Fish
 * 2) Translator (if you cannot speak Vietnamese)
 * 3) Scalpel (2)
 * 4) Tweezers (2)
 * 5) Camera
 * 6) Refrigerator
 * 7) Latex gloves (4)
 * 8) List of criteria determining a healthy fish

(sentences turned to bold mean that the fish have this characteristic)

The fish is a female.Externally, the fish looks quite healthy, however, when we dissected it, the internal organs were physically covered in a green and grey substance instead of a healthy red color, indicating that the fish is not healthy || *** ** Even though it's a fish, it should not smell "fishy" -- it should smell fresh and clean. ** The fish is found to be a male. Externally, the fish looked fine, however, the internal organs were covered in a green grey substance. ||

The fish is identified as a female.There was not as much green grey substance in comparison to the other fish. So far, the most healthiest fish we have seen so far. this fish also carry a very large amount of eggs. || *** ** Even though it's a fish, it should not smell "fishy" -- it should smell freshand clean. **

The fish is a female as we found eggs in it. The internal organs of the fish are in green grey color however, it is not as much as the other fish. The inside of the fish has a distinct "rotten" smell ||

The fish is a female as we found eggs in the fish. The color of the organs were a bright green color in contrast to a bright, healthy, red color. The fish also contained liquid green substance inside, covering it's organ with this substance. ||  ||
