The Undergrads Reuse Their Needles....

to give doses of LHRA  female carp in order to induce egg deposition. Here is a video of this ocurring:

I can't believe the nasty pond they jump into in order to net these fish. I will have you know that sewage is not dealt with the same way we do it in the US. At the University, it is piped to ditches along the perimeter of the the property. So I am sure some of that has ended up in this pond. I guess something has to feed the fish.

They then chose the ripe females and a couple of males. The way to sex these fish is pretty neat. If you pull on the pectoral fin of a male their tail will move. Its kind of like when you scratch a dog behind the ear. (Men, we're just so simple.) This at first had me wondering why all these students keep pulling and massaging fish pectoral fins. You can also tell if the brood sac is large and puffy (filled with eggs). The picture below shows a female and a male fish.





Here is a video of one student demonstrating how the male sperm is extracted (Its a little unclear):

The students were also required to count fish fry, 6000 to a bucket and they told me all of them had to be counted in the one large bucket. I am still not sure if I believe that since there were easily over 100 thousand. Here is a picture of that tedious lab work



Here is a picture of some baby snake head that being raised in the hatchery. These are the types of fish my study deals with.

Hope you enjoy the pictures and videos. Please let me know if these videos do not work. Also feel free to post on the wall. I always enjoy seeing who is reading this stuff.
