Brief Project Summary:

Four strains of largemouth bass from different states were collected to evaluate strain and family growth response to soymeal diet and fishmeal-based diet. A study on evaluation of growth response of northern and southern sub-species to soymeal diet and fishmeal-based diet was completed. Northern sub-species grew significantly faster and gained significantly higher body weight than southern sub-species. Northern sub-species also utilized soymeal diet significantly better than southern sub-species. Based on feed efficiency, 12% dietary soybean meal inclusion is optimal for Southern largemouth bass, while 25% soybean meal can be used in diets for Northern largemouth bass.

Key Audience:
Geneticists, aquaculture nutritionists, aquaculture feed producers, largemouth bass producers

Information And Results
Project Deliverables

Develop and provide educational and promotional materials geared toward promoting Midwest aquaculture products, and disseminate results from objective 1 to Midwest and China.

Two manuscripts have been completed from above results and are being submitted.
Based on the experiment one and current experiment 2, educational and promotional materials geared toward promoting the Midwest aquaculture products are in preparation and will be distributed once the 2nd experiment has been completed.

Activities:
• Broodstock culture, selection, and genotyping for producing experimental fish
• Breeding fry production
• Feed training
• Feeding trial with SMD and Fishmeal diet (FMD)
• Progeny genotyping, parentage, daily weight gain (WG) and daily feed consumption (FC) analyses
• Work on quarterly and final reports and technical bulletin
• Presentation of research findings at professional meeting

One year is too short for completing two experiments with this project and producing or obtaining different strains and families took a longer time than expected. See report.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
