“…The thiamine concentrations in walleye eggs collected in the Western Basin of the Lake Erie were similar to those reported in walleye eggs from other water systems, such as Bay of Quinte Lake Ontario (Johnston et al 2005), Dale Hallow and Center Hill reservoirs in Tennessee, Lake James Reservoir in North Carolina (Honeyfield et al 2007) and Lake Oahe in South Dakota (Barnes et al 2005). In contrast to salmonid eggs, in which free thiamine is the major form of thiamine, TPP is the prevalent form in walleye eggs.…”

“…As reported by Honeyfield et al (2007) the accumulation of TPP in walleye eggs can be related to the short embryonic development of walleye (1 to 3 weeks depending of water temperature) and its immediate metabolic requirement. Barnes et al (2005) reported that thiamine concentrations in embryos of walleye dramatically decreased during the first 3 to 4 days of embryo development and only minor reductions occurred later on. These phenomena need to be studied in detail with improved analytical techniques.…”

Egg thiamine concentration affects embryo survival in Lake Erie walleye

et al. 2010

We quantified thiamine in eggs of Lake Erie walleye to determine if differences exist between spawning stocks within the Maumee and Sandusky rivers, both of which drain into the Western Basin. In spring 2004, eggs of walleye were collected in the Maumee River at three occasions (early, peak and late of the spawning run) and in the Sandusky River during the spawning run. After collection, eggs were fertilized with a known amount of milt, incubated and embryo survival was determined at the pigmented eyed stage. Thiamine and its derivatives were analyzed using high performance liquid chromatography. Thiamine pyrophosphate (TPP) was the most abundant form of vitamin B 1 present in eggs (60-95% of the total vitamin B 1 concentration). Total thiamine concentrations in walleye eggs from the Maumee and Sandusky rivers at the peak of the spawning run averaged 6.1±1.6 nmolg −1 and 5.0±2.9 nmolg −1 , respectively. Our results also indicated that Maumee River stock survival to the eyed stage embryo declined as the spawning season progressed (72%, 59% and 37% in the early, middle and late of spawning run, respectively) as well as the total thiamine and TPP concentrations. At the peak of the spawning run, survival to the eyed stage embryo did not differ significantly between stocks 59% versus 65% in the Maumee and Sandusky rivers, respectively, and thiamine concentrations were not significantly different between sites.

“…Total thiamine concentrations in Lake Winnipeg S. vitreus ova were more than double those of the Great Lakes populations. Ova total thiamine concentrations for the Great Lakes S. vitreus stocks were intermediate between those reported for successfully reproducing populations in North Carolina (Honeyfield et al , 2007) and South Dakota (Barnes et al , 2005). Given that the Great Lakes populations are self‐sustaining, it appears that reproduction is not impaired and ova thiamine concentrations are presumably not limiting.…”

“…Many S. vitreus populations consume forage fishes that are known to have high thiaminase activity including alewife Alosa pseudoharengus (Wilson), rainbow smelt Osmerus mordax (Mitchill) (Tillitt et al , 2005) and threadfin shad Dorosoma petenense (Günther) (Honeyfield et al , 2007), and thus, ova thiamine content could be compromised. Ova thiamine status has been examined for a few S. vitreus populations (Barnes et al , 2005; Honeyfield et al , 2007) but the relationships between ova thiamine provisioning and maternal characteristics are yet to be explored extensively.…”

Concentrations of the various forms of thiamine (vitamin B(1) ) were determined in walleye Sander vitreus ova from three central North American lakes. Total thiamine concentrations in ova from Lake Winnipeg S. vitreus were approximately three times greater (mean 12 nmol g(-1) ) than in those from Lakes Erie or Ontario. The percentage of thiamine in the active form (thiamine pyrophosphate, TPP) was highest in Lake Ontario ova (mean 88%) and lowest in those from Lake Winnipeg (mean 70%). Neither ova total thiamine concentration nor per cent ova thiamine as TPP showed any consistent relationships with maternal age, size, morphometric condition, somatic lipid concentrations or liver lipid concentrations. Ova total thiamine concentration, however, was negatively related to ovum size in some populations, as well as among populations, and was positively related to liver total thiamine concentration. Maternal transfer of thiamine to ova appears to be independent of female ontogenetic or conditional state in S. vitreus.

Recruitment is an important driver of fish population abundance and size structure and can be affected by a variety of density-dependent and density-independent factors. Walleye Sander vitreus populations often exhibit variable yearclass strength, which has been attributed to a suite of factors. In this study, we quantified variability in Walleye recruitment, assessed within-lake recruitment synchrony, and modeled recruitment variability for year-classes that were produced from 1988 to 2013 in Lake Oahe, a large Missouri River reservoir. The objectives of this study were to determine (1) whether Walleye recruit annually, (2) whether Walleye recruitment is spatially synchronous, and (3) whether Walleye recruitment is better described by biotic or abiotic factors. The variability of Walleye recruitment was indexed by using gill-net catch of age-2 Walleye across nine locations in Lake Oahe, and factors affecting recruitment were evaluated by using stock-recruit analysis. Over the 26 years that were assessed, all year-classes were present and four exceptionally large year-classes were produced. Recruitment synchrony was apparent among locations within Lake Oahe, but this relationship was largely influenced by the spatial synchrony of the four exceptionally large year-classes and was no longer detectable when those year-classes were removed. The relative abundance of age-4 and older Walleye, taken as an index of spawner abundance, was a poor predictor of Walleye recruitment, indicating that Walleye recruitment was regulated by density-independent factors across the range of observations. The interactive effects of reservoir elevation and elevation change improved model fit to explain 59% of the recruitment variation and indicated that increased elevation from the previous year improved recruitment. Our results indicate that Walleye recruitment may be favored by increasing the water levels in the reservoir in spring. Recruitment is often the most variable rate that influences the abundance and size structure of fish populations (Gulland 1982; Allen and Pine 2000; Hansen and Nate 2014). Year-class strength and subsequent recruitment to a fishery can be influenced by density-dependent effects on juvenile production and survival as well as many densityindependent abiotic and biotic factors. Spawner abundance may influence recruitment through compensatory density dependence, with high juvenile survival at low spawner abundance and low juvenile survival at high
