Lake Sturgeon Growth Rate

This study aimed to compare relative abundance condition factor and growth rate of juvenile lake sturgeon Acipenser fulvescens Rafinesque 1817 among eight sections of a.
Lake sturgeon growth rate. Therefore countergradient variation in growth is expected for spe-cies that occur across wide temperate latitudinal ranges. Vidual age group was consistently the age group most frequently speared in all years. 48 Peter are also.
At Manitoba Hydros Grand Rapids Fish Hatchery Lake Sturgeon are often reared over their first winter to maximize post-stocking survival. 2019-04-17 tions of lake sturgeon Acipenser fulvescens were smaller at a given age than southern populations but they grew at a higher rate when growth was adjusted for expected ther - mal conditions Power and McKinley 1997. However daily length increase declined at 268C.
During overwinter residence in the hatchery the transition point between growth and non-growth for Lake Sturgeon appears to be 10C. The average annual length of all lake sturgeon harvested has shown little variation 53-56 inches from a mean of 545 inches. The curves for growth i n weight of lake sturgeon of these areas i s similar to those for length except that a greater difference i n the rates of growth i s apparent he curves for Lake St.
2016-03-03 growth rates are quite variable throughout its range and depend on temperature food availability and water quality. This study evaluated the relationship between temperature and growth rate of juvenile Lake Sturgeon Acipenser fulvescens and determined optimal temperature for growth based on weight gain and length increase. Maintenance ration was 16 BWd.
Howeverbefore spawning or when traveling to over-wintering locations sturgeon can migrate over 100 km. The growth rate of sturgeon i s highest i n Lake Winnebago which i s the most southerly lake considered. Characteristics of lake sturgeon captured from commercial fisheries in Lake Huron North Channel and Georgian Bay 1995-2003.
Growth rate and size variability among juvenile lake sturgeon Acipenser fulvescens. Siberian sturgeons grow to about 15 meters and attain this much more quickly than sterlets packing on an average of 10 inches per year. This number repre sented about one-half of the number of sturgeon 105 unknowns and 38 males examined by Jolliff and Eckert 1971.
