What the research is about
The objective of this study was to evaluate seasonal, spatial and species effects on fillet quality of Asian carp harvested from the Illinois River. As such, Bighead and Silver Carp were harvested on two occasions (summer and fall) from two geographically distinct reaches (Alton and Peoria) of the Illinois River.
This is the first report of color and Fish Freshness Meter (Torrymeter) freshness values for Silver and Bighead Carp. This can establish a reference for future research in commercial evaluation of flesh quality for these two species.Indicators of shelf life suggest improved product quality for a frozen fish export market can be achieved by concentrating harvest on Silver Carp in the Peoria Reach during the fall season.
Research conclusion
This research documents the effects of season, geographic origin and species on product quality related to shelf-life and visual perception. The latter did not correlate well with predictors of shelf-life in this study. Improved shelf-life was observed for Silver Carp, fall harvested fish and fish from the Peoria Reach.
Assurant Innovations take
Fish Freshness Meter (Torrymeter) was used and found that Asian Carp caught during Fall was “fresher” when compared to “Summer” season.
