Research Project: METHODS TO CONTROL EGG MORTALITY ASSOCIATED WITH AQUATIC FUNGUS (SAPROLEGNIA SPP.) INFECTING HYBRID STRIPED BASS EGGS

Location: Harry K. Dupree Stuttgart National Aquaculture Research Center

Project Number: 6028-32000-005-09
Project Type: Nonfunded Cooperative Agreement

Start Date: Apr 10, 2012
End Date: Mar 31, 2014

Objective:
Develop a therapeutic treatment regimen to minimize the effects of aquatic fungus (Saprolegnia spp.) infecting hybrid striped bass eggs and causing economic losses to the producer.

Approach:
Improved fungus control has been established on catfish eggs from ongoing ARS research at SNARC. Fungus on eggs also causes severe losses in the hybrid striped bass industry. Because of the time-sensitive nature of this research and the rapid hatching of eggs, this research will be conducted at the participating fish farm. Two known treatments for aquatic fungus (copper sulfate and peracetic acid) will be tested at several concentrations to determine their effectiveness.
