Interaction between anglers and coarse fish populations in two gravel-pit lakes
… biology of the coarse fish species in two gravel-pit fisheries (A and B) in Suffolk were studied from 1974 to 1977. Simultaneously the fish caught by anglers and their angling technique were monitored by census. Environmental factors were recorded on each census occasion and the crustacean …

Identifying Optimal Sites for Aquaculture in Southern Ontario Aggregate Pit Lakes: A Sustainable Post-Mining Land-Use Alternative
… the water table. As these sites transition into pit lakes, they are often characterized by low nutrients, steep walls, and limited biological activity. These future pit lakes represent a unique opportunity for repurposing to create positive social and economic impacts. However, effective …

A comparison of growth rates of coarse fish in gravel-pit lakes in south-east England and of population structure in selected lakes
… and growth rates of the coarse fish of 39 gravel-pit lakes in South-East England are compared. Species composition and growth rate are very variable, the commonest species being roach (Rutilus rutilus L.), bream (Abramis brama L.), tench (Tinca tinca L.), perch (Perca fluviatilis L.) and pike …

Relationships between population density feeding and growth of the roach (Ratilus ratilus, L. 1758) and other coarse fish in a gravel-pit lake in Southern England
Gravel-pit lakes are an increasingly common feature of our landscape, particularly on the flood plains of rivers close to large urban or industrial areas e. g. the Thames Valley (see Fig. 1). When sand and gravel are removed from below the water table, lakes are produced by seepage into the …

Comparison of Creel Survey Data to Traditional Sampling Techniques in Pit-Lake Fisheries of Muhlenberg County, Kentucky
… macrochirus</em>, were evaluated from five pit-lakes in Muhlenberg County, Kentucky, to determine if accurate proportional stock density (PSD) data can be obtained from a mandatory creel survey. It was hypothesized that the proportion of stock-to-quality (300-400mm) and quality (+400mm) …

Aquifer Framework Restoration (AFR) in an Alluvial Aquifer, Central Texas.
… BRAA framework are being excavated and kept as pit lakes or filled with different material. GIS identification of mined areas was estimated to cover 4.4% of the BRAA from which evaporative losses was calculated to be 10% of average annual recharge. Permeameter tests suggest that foreign material …

Studies on fungal biomass and activity associated with the decomposition of plant litter in freshwater
… explain this. In field studies on flooded gravel pits biomass was 0.02-6.66/0 leaf dry weight depending on leaf type, biomass method and submersion time. Biomass estimated using clearing and staining was significantly correlated with ergosterol and with the agar film method; the latter gave the …

Relationships between water quality, species composition, biodiversity and ecosystem function in lakes and flooded pits exposed to uranium mining activities in Northern Saskatechewan
… of water quality on aquatic biota within flooded pit lakes and natural lakes that have been exposed to various mechanisms of mining exposure. However, the literature often only examines the effects of a limited number of contaminants on a limited number of species. Researchers have rarely looked …

Geochemistry of Arsenic, Manganese, and Iron in the Dexter Pit Lake, Tuscarora, Nevada
The Dexter pit lake is a mine pit lake located in north-eastern Nevada, located in the Tuscarora volcanic field. The pit lake formed in 1990 following cessation of open-pit gold and silver mining operations. This pit lake has been the subject of previous geological study, which served to outline …
