Growth and Appetite of Juvenile Lake sturgeon Acipenser fulvescens
–Growth rates of juvenile lake sturgeon (initial weight 8 to 9 g, temperature 17.5° C), fed twice a day on brown worms for 56 days increased from -1.5% BW/d (% body wet weight/day) at zero ration to 2.6% BW/d at a ration of 13.2% BW/d. Maintenance ration was 1.6% BW/d. Fish fed larger rations had higher energy densities and lower water content. Appetite (average volitional daily food consumptio...
متن کاملMultiple molecular approaches yield no evidence for sex-determining genes in lake sturgeon (Acipenser fulvescens)
Common DNA-based sexing assays have been widely used for the conservation and management of mammals and birds. However, many fishes do not have genetic sex determination and in those that do, the plasticity of the genes involved means that species-specific assays are normally required. Such DNAsexing markers would be especially valuable in lake sturgeon (Acipenser fulvescens) because of their s...

متن کاملCoding of sound direction in the auditory periphery of the lake sturgeon, Acipenser fulvescens.
The lake sturgeon, Acipenser fulvescens, belongs to one of the few extant nonteleost ray-finned fishes and diverged from the main vertebrate lineage about 250 million years ago. The aim of this study was to use this species to explore the peripheral neural coding strategies for sound direction and compare these results to modern bony fishes (teleosts). Extracellular recordings were made from af...
متن کاملAPPLYING INSTREAM FLOW INCREMENTAL METHOD FOR THE SPAWNING HABITAT PROTECTION OF CHINESE STURGEON (Acipenser sinensis)
The Chinese sturgeon, Acipenser sinensis, is an anadromous species that spawns in the Yangtze River and Pearl River of China. Its population has declined dramatically since the construction of the Gezhouba Dam (GD) in 1981 and then with the impoundment of the Three Gorges Dam (TGD) upstream of the GD in 2003. This paper presents a quantitative method based on the instream flow incremental metho...
