Their nutritional status tended to be higher during the stocking period than before stocking in stocked rivers, but not in unstocked rivers. These results suggest that the massive stocking of chum salmon fry provides brown trout with the perfect prey to quickly restore ...
Adult rainbow trout, with an average weight of 1.517kg (卤0.39), were subjected to low (12kg/m3卤0.94) and moderate (43kg/m3卤2.03) stocking densities for 24 days in a recirculating system maintained at 15掳C. At the end of the experiment, fecal microbiome analysis was carried out using...
Given that managers rely on the number of young of the year (YOY) fish to evaluate stocking success, this knowledge gap poses a major challenge. We studied effects of two stocking levels on YOY brown trout at different downstream distances (0–600m) from the stocking point. Density increased...
We suggest that brown trout outcompete charr for habitat and food resources, and that stocking charr in streams in which brown trout populations exist is unlikely to be effective in the management and restoration of recreational fisheries, but that stocking them into streams in which brown trout ...
