Keeping Quality

Slime from several freshwater fish species was a good bacteriological medium and supported growth of 109–1010 organisms per gram. Fish stored at 3 C became inedible after several days even though the flesh contained few bacteria. Diffusion of metabolic products resulting from bacterial growth on the slime produced strong odors and flavors in the flesh. Under commercial conditions, washed lake whiteflsh (Coregonus clupeaformis) had lower bacterial numbers and coliform counts and higher organoleptic ratings than unwashed samples.

The Difference

The effect of polyphosphate treatment on thaw drip was determined on six freshwater fish species. No relation could be found between state of rigor and thaw drip in control and treated fillets or increase in weight due to dipping. Thaw drip was reduced by an average of 60% as a result of treatment. The difference in weight between control and treated fillets after thawing averaged 5% or more of the initial weight in favor of the treated products. A difference in taste could be detected in yellow walleye (Stizostedion vitreum) and in whitefish (Coregonus clupeaformis) samples, but preferences were equally divided between treated and untreated samples.

Fish Pass

AbstractAlthough small benthic freshwater fish species are an important biological component of fish assemblages and free instream movement is indispensable for their survival, they are often neglected in fish pass performance studies. In this study, a capture-mark-recapture approach was used to assess whether small bottom-dwelling species, including gudgeon (Gobio gobio), stone loach (Barbatula barbatula), spined loach (Cobitis taenia) and bullhead (Cottus gobio), were able to cross a pool-and-weir fish pass in a regulated lowland river. Some tagged individuals of stone loach (18%), gudgeon (7%) and spined loach (2%) managed to successfully ascend the fish pass under study, despite the fact that water velocity levels in the different overflows of the facility (between 0.55-1.22 m/s) exceeded the critical swimming speed of all three species. Although this suggests that a pool-and-weir fish pass is a able to facilitate upstream movement of some small benthic species in a regulated river, more detailed research incorporating advanced tagging and retrieving techniques is necessary.
