Finally, after the feeding trials the bass were moved to outdoor ponds for 30 days ... Mortalities did occur after transfer of the bass to the outdoor ponds, 12% of the total sample. For the surviving fish new symptoms of disease, for example fungus around the eyes, top of the head and gills were observed after 30 days in 8% of the sample. These symptoms could be the result of the handling manipulations. However, there was no difference in the frequency of occurrence of these symptoms or in the number of mortalities among fish from the different treatments.
What did we learn? It was clear that fish in the two-handed support treatment recovered the fastest. The one-handed jaw only horizontal hold caused the most disruption. It had a relatively moderate recovery time similar to the supported hold but required major head shakes and multiple jaw adjustments in many cases in order for the fish to right itself. However, we saw no permanent jaw damage as a result of handling. The vertical grip had prolonged recovery times compared to the other two groups but we saw no major head shakes or evidence for jaw damage.

Subject: "All About that Bass" Project Updates and Summary
Hello All,
The bass handling project 'All about that bass' is in the final stages. We completed the experiments last summer and this past fall and winter was spent analyzing hours of underwater video. We recently got a nice write up published in B.A.S.S. Times (a BassMaster publication) summarizing the study and results. A scientific article is in the works and has been sent out for peer review. Attached to this email is summary material along with links to some video clips showing the post-treatment recovery assessment and feeding trials. We will keep you informed if more information is published. Thank you for your support and interest in black bass conservation.
