Graduate Exit Seminar via Zoom - Kevin Fisher

Plan to join via Zoom Kevin Fisher's graduate exit seminar on Thursday, April 23, 2020, at 10:00 a.m. Kevin will present, "Novel aspects of Bighead carp sperm storage and larval/juvenile rearing to address control of invasive Asian carp in the


Bighead carp, Hypophthalmichthys nobilis, is native to Asia and was introduced to the United States as a species of interest for aquaculture in the 1970s but escaped from captivity soon after. They are currently widely spread throughout the Mississippi River Basin and potentially threatening to invade the Great Lakes, which could impact a multi-billion dollar sport fishery. Current control efforts have focused on preventing further spread through constructing barriers and physical removal of adults near the invasion front. Alternative methods for biocontrol of invasive fish species are becoming increasingly attractive and show promise as another tool which can potentially control or eliminate specific invasive populations. These methods rely on technology designed and implemented in aquaculture such as sex reversal, polyploidy and mass production of offspring. A series of experiments were conducted to investigate novel aspects of sperm storage for in vitro fertilization and to improve intensive larval/juvenile rearing of bighead for application in biocontrol breeding programs.
