Conservation of barbel (Barbus barbus) in the River Great Ouse
… were used to assess fine sediment infiltration. Larval drift measured the number of larvae leaving the spawning grounds, a range of methodologies were used to capture 0+ to 3+ barbel. Habitat and feeding preferences were then evaluated.It was found that temperature and flow impacted movement, …

Sedimentological and Biological Analyses on Hobble Creek Prior to Restoration
… patterns and existing small fish densities. Larval drift modeling was performed to characterize the ability of the stream to transport larvae to the zones studied. We found that highest food density occurs in the open lake; small fish were most abundant in the open lake as well. The open lake …

Early-Life History of the White Sucker (Catostomus Commersoni) in Lake Taneycomo, Missouri
… of spawn and hatch dates was back-calculated in larval white suckers. Hatching was found to occur over 43 day period in 1994, and 25 days in 1995. Timing of initial otolith annulus formation was determined in the young-of-the-year fish, with 100% of the juveniles sampled forming an annulus their …

Spatial modelling of blue whiting population dynamics in the north-east Atlantic
… depended on spawning distribution and larval drift. In the model, the population response to varying fishing pressure was significantly affected by both recruitment and individual growth. I suggest this model as a tool to test and study different fishing behaviours or fishery management …

Quantification of Variability, Abundance, and Mortality of Maumee River Larval Walleye (Sander vitreus) Using Bayesian Hierarchical Models
… of conventional abundance estimation methods. Larval walleye in the Maumee River are extremely variable; however estimates of abundance and mortality are important in understanding anthropogenic impacts on this spawning group and their role in Lake Erie walleye recruitment. Bayesian …
