Survey Of Cultchless Spat Planted By The Vmrc In Nomini And Lower Machodoc Creek, Dexter S. Haven

Reports

As part of a major repletion activity by the VMRC, cultchless spat were planted in Lower Machodoc Creek and Nomini Creek in October and November 1973. The Virginia Institute of Marine Science surveyed these plantings on 10 and 11 December, 1973. The areas planted and surveyed are shown in figures 1 and 2.

In Lower Machodoc Creek, 5.35 acres were planted with 240.5 bushels of cultchless spat during October, 1973. Within this area, five sub-areas were seeded, each with about one million spat. In Nomini Creek there were two planting areas. The largest was located in Nomini Cut, and seven …

A Preliminary Report To The Virginia Department Of Highways On Hard Clam (Mercenaria Mercenaria) Populations In The Vicinity Of The Hampton Roads Bridge-Tunnel (I-64) (Segment 268-135d), Dexter S. Haven, Paul Kendall, Reinaldo Morales-Alamo

Reports

1-664 will be constructed in Hampton Roads in an area where the hard clam Mercenaria mercenaria is fished commercially. Because of this c.lam's economic value and because Hampton Roads is the major producing region for this species, it is worthwhile that every precaution be taken during construction of I-664 to minimize the possibility of .damage to this resource. ·To achieve this objective, we are evaluating the possible impact of construction activities around I-64 and adjacent areas on populations of the hard clam. The aim is that if damage or potential damage. is noted around I-64, then construction techniques may be …

Inventory Of Surf Clams In Nearshore Waters From Cape Henlopen To The False Cape Area : Quarterly Progress Report, September 16, 1974 - December 15, 1974, Joseph G. Loesch

Reports

A survey of the surf clam@pisula solidissima) in the nearshore area along the Delmarva Peninsula and further offshore from Cape Henry to upper North Carolina was conducted from 4 October, 1974 through 15 October, 1974. The project is a joint undertaking by the National Marine Fisheries Service (NMF'S) and the Virginia Institute of Marine Science (VIMS). A total of 138 sites were sampled with a hydraulic tow dredge and, in addition, a benthic sample for juvenile clams were obtained at each site with a Smith-MacIntyre sampler.

A Final Report To The Virginia Department Of Highways On Hard Clam (Mercenaria Mercenaria) Populations In The Vicinity Of The Hampton Roads Bridge-Tunnel (I-64), Dexter S. Haven, Paul Kendall

Reports

I-564 will be constructed in Hampton Roads in an area where the hard clam Mercenaria mercenaria is fished commercially. Because of this clam 1s economic value and because Hampton Roads is the major producing region for this species, it is worthwhile that every prer:: aution be taken during construction of I-664 to minimize the possibility of damage to this resource.

To achieve this objective, this study was undertaken to evaluate the pwsible impact of I-64 and of construction activities around I-64 on adjacent populations of the hard clam. The objective of the study was that if damage or potential damage …
