The elastomer injection was made at the base of the anal fin and on the operculum (razorback suckers) or lower jaw (Colorado squawfish) and consisted of one of four colors: green, blue, red, or orange. Freeze branding had 99% retention after 15 months for both species. Elastomer recognition was better for Colorado squawfish (mean 74%) than for razorback suckers (mean 60%) after 15 months, and retention at both locations was similar. Red and orange had the best recognition and blue had the poorest. Red and orange elastomer injected in young Colorado squawfish could be detected (95%) for 5 months. One person implanting elastomer at two locations on each fish and one person anesthetizing and handling fish can mark 130–140 fish/h.

Static toxicity tests were conducted on eight unionid mussel species with common aquaculture chemicals (benzalkonium chloride, formalin, hydrogen peroxide, calcium chloride, potassium chloride, and sodium chloride). The concentration and duration of each chemical treatment tested had previously been found to kill zebra mussel veligers and juveniles. Several species (e.g., Elliptio dilatata, Lampsilis cardium and Lasmigona complanata) incurred less than 10% mortality in chloride salt treatments, while in other species (e.g., Obliquaria reflexa and Leptodea fragilis) mortality varied greatly among treatment regimes.

Increasing DI (from 0.0 to 0.5) also improved feed conversions and slightly depressed survival, but DI had no significant effects on weight gain, condition (K), or carcass composition. Water temperature (10°C or 15°C) had a strong and significant effect on DFI; colder water improved DFI while slowing body growth. Low temperature treatments improved survival slightly and altered carcass composition by increasing moisture at the expense of fat and protein.

Growth and migration of the mussels inside the tank were recorded over a 3-month period. Small mussels (1–3 mm) migrated frequently and had a high mortality rate (>99%). The mortality rate of the larger mussels (>12 mm) was lower (25%). Larger size mussels seldom migrated, but they did not increase in size during the entire 3-month period. Medium-size mussels (3–12 mm) exhibited strong photophobic behavior. Significant growth was observed in individuals that settled in dim places away from rapid water current.
