When a washtub was filled up with illegal-size shovelnose sturgeon (i.e. The three sampling loca- tions were chosen such that individuals from the upper, mid-dle, and lower sections of the study area were represented. In the spring, adults move far upstream and away from saltwater, to spawn. Shovelnose sturgeon prefer habitat at or near the bottom of large, unregulated, turbid rivers with relatively warm water that is essentially free of chemical contaminants. American Hackleback Caviar quantity . Season-Specific Limits. (FWP) In Montana, shovelnose sturgeon appear to utilize primarily large rivers (Bramblett 1996), but also use reservoirs to some extent. 45335); platorynchus: From the words platy, meaning broad and rynchus, meaning snout (Ref. In past years, this sturgeon was exploited as food and byproducts. Overall, its numbers have decreased sharply since 1900, but it still remains abundant off the main channels of the Missouri and Mississippi. Beamesderfer, Ruth A. Farr, Alternatives for the protection and restoration of sturgeons and their habitat, Sturgeon Biodiversity and Conservation, 10.1007/0-306-46854-9, (407-417), (2002). Beamesderfer, Ruth A.

The pallid and lake sturgeon are endangered and need to be protected. Habitat use by wild age‐0 shovelnose sturgeon Scaphirhynchus platorynchus and pallid sturgeon S. albus was quantified by trawling macrohabitats (i.e., main channel, main‐channel border, island, and artificial structures [e.g., wing dams]) in the middle Mississippi River during 1998–2007 (1,702 trawls; n = 1,507 age‐0 sturgeon captured). Dates. The Missouri River and the Mississippi River systems tend to carry high sediment loads. An empirical growth rate of 2.67 mm/year was observed for fish larger than 635 mm, with several individuals showing negative growth. Read about how we use cookies by visiting our "Privacy and Terms." The most readily distinguishing characteristic of the shovelnose is its small size and dark color. Switchtail refers to the long filament found on the upper lobe of the caudal fin (often broken off as adults). It is the only known host to the hickorynut mussel.[4]. Although not commonly available for sale, the Shovelnose Sturgeon's adult size of up to 3ft in length makes it an ideal alternative to the Sterlet (Acipenser ruthenus). Upper and lower lips each have four distinct fleshy lobes. Steve Waugh shows off the 8-pound, 3-ounce, 40-inch shovelnose sturgeon he caught and released last month while fishing in the Minnesota River. The shovelnose sturgeon rarely exceeds 5 lbs in weight, while the pallid can exceed 6 ft in length and weigh over 100 lbs. Carlson et al. 45335); platorynchus: From the words platy, meaning broad and rynchus, meaning snout (Ref. Native to the river basins of Mississippi and Missouri, hackleback has become a popular alternative to the more traditional sturgeon roes. The shovelnose sturgeon, as its distribution represents, is impacted very little by turbidity. They can reach 1m (39.4 in) in length and up to 4.8 kg (10.6 lb) in weight but 50–85 cm (19.7-33.5 in) and 2.5 kg (5.5 lb) is more common. Etymology/Derivation of Scientific Name . Shovelnose sturgeon were sampled seasonally from the Middle Mississippi River to account for all stages of reproductive development. [5] The flesh of the sturgeon is widely considered a delicacy, especially smoked sturgeon.

We describe gender and reproductive development of 306 shovelnose sturgeon from the Middle Mississippi River (River km 0–322) during September 2001 through December 2003. Flowing water over sand or fine gravel substrates is preferred. Product Description. Kent D. Keenlyne, Life history and status of the shovelnose sturgeon, Scaphirhynchus platorynchus, Sturgeon Biodiversity and Conservation, 10.1007/0-306-46854-9, (291-298), (2002). In shovelnose sturgeon from the Chippewa River, the adhesive eggs appear to fall into three major groups: (1) yellow and/or white, (2) white and black, and (3) black (the mature eggs in the enlarged ovaries). Spawning takes place over gravel in fairly swift water. Fifteen-minute critical swimming speeds were de~ermined for a limited number of wild- caught, adult shovelnose sturgeon that ranged in size from 57 to 69 cm fork length (Adams et al. To address this, I developed a guide for shovelnose sturgeon reproductive development in Chapter 3. All four barbels are evenly spaced under the jaw, unlike the related pallid sturgeon, which has barbels unevenly spaced under the jaw. 1985. Shovelnose sturgeon are potamodromous meaning they undertake regular migrations in large freshwater systems. The maximum recorded size is 1m in length and 4.8kg in weight but 50 - 85cm and up to 2.5kg is more usual. 1997). The fish now is common in the Mississippi Basin, rare in Mobile Bay drainage and extinct in the Rio Grande. However, after about 1900, the shovelnose sturgeon was recognized as being valuable as a smoked fish product and its roe is valued as caviar. Also, the belly of the adult shovelnose sturgeon is completely covered with bony plates and the barbels are positioned differently (see figure above). Haverland. Unlike Atlantic sturgeon, shortnose sturgeon tend to spend relatively little time in the ocean. The smallest and most common sturgeon in Montana is the shovelnose sturgeon. Pale to medium gray or brownish dorsally and white below. The sturgeons of the family Acipenseridae have bony scutes along the sides and back and four barbels on the underside of the rostrum. The largest recorded shovelnose was approximately 35 inches (900mm) from head to tail, and weighed close to 8 pounds (3 - 4kg). Females were significantly larger than males for both species although there was overlap. Sturgeon in this study ranged from 3 to 10 years of age and ranged in size from 18 to 23 inches total length ( 16-20.5 FL). Diets of the young pallid sturgeon will be compared with diets of young shovelnose sturgeon of the same size and age, collected in the same habitats. under or over the harvest slot size) or legal fish that were thought not to be gravid females (note: most sturgeon were harvested because fishers thought they were gravid females), we would off-load those fish into our boat for processing [FL (mm); weight (g); fin ray sample for aging]. [1] It inhabits quite shallow flowing waters that are turbid and muddy. They are found at depths ranging from 0.9 to 10.1 m and averaged 2.29 m (Bramblett 1996). Electrofishing CPUE was the highest reported in any study on Shovelnose Sturgeon. Spawning is reported to occur from April to June in large rivers in areas with rocky substrates and swift currents. Captured fish ranged between 61 and 909 mm FL (mean = 662 mm; median = 671 mm), but few fish were smaller than 500 mm. Shovelnose Sturgeon. The average length of an adult shovelnose sturgeon is about 21 inches and the average weight is 1.5 pounds.

The scientific name Scaphirhynchus, Greek, means "spade snout," and platorynchus, Greek, means "broad snout." Shovelnose sturgeon from the Yellowstone–Williston segment grew significantly faster and reached a larger size than shovelnose sturgeon from the Bismarck segment. There are four fringed barbels on the ventral side of the rostrum that can be found in a straight line, which is equidistant from the mouth opening to the tip of the snout, unlike pallid sturgeon. In their original description, Forbes and Richardson (1905) noted that pallid sturgeon differed from shovelnose sturgeon in size, color, head length, eye size, mouth width, barbel length ratios, ossification, gill raker morphology, number of ribs, and size of the air bladder. Although the fish were in good condition (mean relative weight = 89.9), there was a decreasing trend in mean condition over time. Shovelnose Sturgeon. Although not commonly available for sale, the Shovelnose Sturgeon's adult size of up to 3ft in length makes it an ideal alternative to the Sterlet (Acipenser ruthenus).
