Southern Nevada Effluent Wetlands: A Proposed Cooperative Venture Between The Bureau Of Reclamation & City Of Las Vegas, Bureau Of Reclamation

Publications (WR)

Throughout North America there is a growing interest in constructed wetlands, both as relatively inexpensive, low-maintenance systems for removing nutrients from wastewater, and as a means of using municipal wastewater to enhance wildlife habitat and create public use opportunities. Because wetlands appear to have good potential as a component in the overall management of scarce water resources, the Bureau of Reclamation (Reclamation) has undertaken several cooperative research and demonstration projects to evaluate their effectiveness in a variety of local environments.

While a number of projects have demonstrated that wetlands can be beneficially employed to improve water quality, few such projects …

The Cockburn Sound Fishery Management Plan. Summary Of Submission And Final Recommendations For Management., A. Millington

Fisheries management papers

Identifiable "unit" fisheries in Cockburn Sound are: Beach bait fishing netting Fish set netting Crab netting Mussel diving Line fishing and pot fishing This report recommends measures for the longer term management of these fisheries In particular, that they be managed as limited entry fisheries under Section 32 of the Fisheries Act 1905. Strict entry criteria are proposed for continued access to these fisheries. Rules are proposed for boat replacement. Licence transferability is considered in detail. No decisions to be made on the policy for licence transfers until the final number of participants in each fishery is determined. Owner operation, …

Characterization Of Polycyclic Aromatic Hydrocarbons (Pahs) By The Kinetics Of Depuration In Bivalve Molluscs, Mercenaria Mercenaria, C Sato, H Kim, John T. Tanacredi Ph.D.

Faculty Works: CERCOM

The objectives of this study were to examine depuration aspects of polycyclic aromatic hydrocarbons (PAHs) in a hard-shell clam Mercenaria mercenaria, and to characterize PAHs by the depuration kinetics. In this investigation, clams were exposed to artificial sea water containing a mixture of eight PAHs (i.e., naphthalene, fluorene, phenanthrene, flouranthene, pyrene, benz[a]anthracene, chrysene, benzo[a]pyrene) for 48 hours. The clams were then transferred into clean (PAH-free) artificial seawater for release, and sampled at predetermined intervals. The target PAHs were extracted from the clam tissue and quantified by a gas chromatograph equipped with a capillary glass column and FID.

The results …
