Bioaccumulation of Sediment Contaminants by the Benthos of the Quinnipiac River

Organization: 
Yale University Grant and Contract Administration
Date Issued: 
Amount: 
20 000.00
Description: 
To support the project entitled Bioaccumulation of Sediment Contaminants by Benthos of the Quinnipiac River.  This proposed research is an investigation of the sediment contaminant load of two sites in the Quinnipiac River and the availability of the contaminants to the benthic organisms living in them.

Research on Tidal Wetland Plants

Organization: 
Univ. of Connectict, Dept. of Ecology & Evol.
Date Issued: 
Amount: 
5 000.00
Description: 
Research on tidal wetland plants in the Quinnipiac River estuary related to wetland restoration.

This grant resulted in the publication of a research paper, entitled "The mycorrhizal status of selected plant species from Connecticut wetlands and transition zones". The abstract is available in the "YEAR END REPORTS" file below. For access to the full article, you will have to log into a scholarly database via an institutional or society membership.

Restoration of 9.4 acre parcel along Q'River

Organization: 
The New Haven Land Trust, Inc.
Date Issued: 
Amount: 
5 000.00
Description: 
To conduct restoration of its 9.4 acre parcel along the Quinnipiac River to remove rubble and debris degrading tidal wetland on the parcel.

Assess Tautog Embryos

Organization: 
National Marine Fisheries Service
Date Issued: 
Amount: 
4 700.00
Description: 
Use plankton net to collect tautog embryos and assess their viability in New Haven Harbor.

Spawning cycle and embryo viability of tautogs assessed in New Haven Harbor. Found peak spawning time during summer, decreased as progressed, and found reasonably low levels of contamination, though viability decreased the later spawning occurred during spawning season.

Document the Macrobenthic Structure of River

Organization: 
Southern Connecticut State University
Date Issued: 
Amount: 
4 738.90
Description: 
To document the macrobenthic structure of the lower Quinnipiac River as an "ecological benchmark" against future changes.

Evaluate healthiness and diversity of benthic communities in lower Qriver and assess effect of environmental stressors on these communities. High stability and consistency of assemblage of species found. Moderately stressed conditions also found.

Classify/Assess Shellfish

Organization: 
CT Dept. of Agriculture/Aquaculture Division
Date Issued: 
Amount: 
5 160.00
Description: 
To classify and assess shellfish growing water for the Quinnipiac River and New Haven Harbor.

Shellfish (mostly oysters) collected from Q river and New Haven harbor and level of pollutants found to be high. Also assessment of sewage overflow conducted in area and violations noted.

Assess Contaminants in Winter Flounder

Organization: 
National Marine Fisheries Service
Date Issued: 
Amount: 
5 000.00
Description: 
To assess relative abundance, health and body burden of selected contaminants in winter flounder.

Study of fish size, skeleton, pollutant body burden, number of overall fish and species diversity indicated that Hemingway Creek was not an appropriate location for the growth of young winter flounder.

Collect/Examing Winter Flounder Eggs

Organization: 
National Marine Fisheries Service
Date Issued: 
Amount: 
4 890.00
Description: 
To collect and examine winter flounder eggs for condition and viability.

Fish were tagged and eggs collected; results unexpected. Winter flounder tend to spawn in light house point-morris cove area instead of in long wharf/Q river area. Fish eggs tended to be healthy.

Survey of Symbiotic Roots Showing Mycorrhizal..

Organization: 
UNIVERSITY of CONNECTICUT DEPT. OF ECOLOGY
Date Issued: 
Amount: 
4 472.00
Description: 
To continue "Survey of Symbiotic Roots Showing Mycorrhizal Fungi on Tidal Riverine Vegetation in the Lower Quinnipiac River".

Further data was collected from mycorrhizal fungi. Ascertained that diversity could not be accounted for by soil sample alone. Requires further exploration.

Survey

Organization: 
University of Connecticut Dept. of Ecology
Date Issued: 
Amount: 
3 500.00

Fewer mycorrhizal fungi colonies were found in the tidal riverine wetlands around the Qriver than in comparable non-developed areas; troubling environmental ramifications.
