Goal
To see if BPA(
Bisphenol
-A) will have any affect on the aggressiveness of Beta fish
.
Slide3
What We Want to Prove
Ultimately we want to be able to show that BPA interrupts the production of male hormones, concluding that BPA mimics
estrogen, causing
the body of the
Betta
fish to feminize
.Slide4
BPA(Bisphenol-A)
BPA is a carbon based compound that has been
commercially used since 1957.
It is used to make a tough and clear plastic, and is found in many different items such as: baby bottles, water bottles, CD’s, DVD’s, and sports equipment.
At a high dosage BPA can be harmful do fetuses, infants, and young children. Resulting in the FDA banning the use of BPA in baby bottles, and
sippy
cups.Slide5
Beta(Betta splendens
) Fish
The Beta fish is an extremely aggressive fish.
It has bright colors, and large flowing fins that fan out when it comes in contact with a threat.
When in the wild the
Betta
fish will feed off of zooplankton, crustaceans, and the larvae of mosquitos and can grow up to 6.5 cm long.Slide6
Steps
We have ten
Betta
fish each in their own tanks. Each containing 1L of water.
The first week we had the tanks separated by pieces of paper acting as a blind so they would not be stressed out by the other fish. The blind was then removed showing each fish to their neighbor. Once they started to show aggressiveness a timer was started for ten minutes and each separate
Betta
was timed every time its fins flared up.Slide7
Steps cont.
After every
Betta
was timed we gave them a days rest and then added 1mL of BPA(.045 grams/Liter) to each tank.
We have given them one whole week to absorb as much BPA as possible, and starting Wednesday we will be timing them again to see if the BPA reduces the time that they show aggressiveness.
