If you want a research job, either go to a top 25 undergrad college or write a kick ass thesis. (Second one requiring the ability that would have helped you achieve the first.)
There's just not enough money for someone starting out. I've got a fairly good shot at an animal keeper job at the NY Aquarium because I've interned and docented there in the past, but it starts at about $36,000 before taxes.
As for ichthyology, it's not as amazing as you may believe. I interned in the Department of Ichthyology at the AMNH during high school, and it was fun- but it's not something I'd want to do every day. Aside from collecting trips and foreign expeditions are the hours in the laboratory doing lateral line and caudal peduncle scale counts to note species differences between similarly appearing fish. Additionally, it's a rather difficult field to get into- all of the staff scientists there had doctorates and the least experienced employees were working on their doctorates.
