High Phytoplankton Growth And Production Rates In Oligotrophic Hawaiian Coastal Waters, E. A. Laws, Dg Redalje, Larry W. Haas, P. K. Bienfang, Rw Eppley, W. G. Harrison, David Karl, J. Marra

VIMS Articles

Plankton biomass, material fluxes, e.g. 14C uptake, and specific growth rates are related quantities. In the course of comparing various methods of measuring these properties in September 1982 off Oahu, Hawaii, we found specific growth rates of 1–2·d−1. Such rates approach the maximum expected values observed in laboratory cultures.

Feasibility Of Commercial Fishing Operations In The Mid-Atlantic Continental Slope, Philip W. Cahill, P. Ronald Grulich, James A. Colvocoresses

Reports

The objective of the project was to test the feasibility of conducting commercial trawling operations in the slope waters ( 100 fm-300 fm) adjacent to the traditional fishing areas on the continental shelf in the Mid-Atlantic Bight. This was to be accomplished by developing a fishing strategy that would be structured around existing information on stock abundance, type and location and implementing the fishing strategy by procuring a lease on a commercial fishing vessel that would be suitable for slope trawling. The implementation of fishery operations would be the primary goal of the project and every effort would be made …

The Dedication Of Waterman's Hall Of The Virginia Institute Of Marine Science, School Of Marine Science, The College Of William And Mary, Virginia Institute Of Marine Science

Miscellaneous

Date of dedication: June 29, 1984. The dedication of Waterman's Hall marks a significant event in the Institute's history. This new 40,330 square foot facility, designed by VVKR, Inc. and built by American Eastern, will provide modern facilities for the graduate and public education programs of the School of Marine Science, house the Institute's Department of Advisory Services, afford the Institute the space to properly display and utilize its extensive marine science library, and provide for the centralization of administrative offices.

Rib Number And Shell Color In Hybridized Subspecies Of The Atlantic Bay Scallop, Argopecten Irradians, John Kraeuter, Laura Adamkewicz, Michael Castagna, Robert Wall, Richard Karney

VIMS Articles

Bay scallops, Argopecten irradians (Lamarck), from populations with low rib number (Texas) and high rib number (Virginia) were bred separately and also hybridized. The results suggest that rib number is under genetic control and that the two populations are genetically differentiated. Scallops taken from a population polymorphic for shell color (Massachusetts) were bred in groups, each group containing a single color. The results suggest that color is also under genetic control and is not strongly influenced by the environment

A New Species And A Review Of The Deep-Sea Fish Genus Porogadus (Ophidiidae) From The Western North-Atlantic, Hj Carter, Kj Sulak

VIMS Articles

A new species of deep-sea ophidiid, Porogadus situs, is described from deep water off the Bahamas, It differs from its congeners chiefly in having a relatively shorter and deeper head, absence of preopercular and frontal spines and relatively large scales covering the body. A partial osteological description of P. situs is given. porogadus is reviewed and a provisional key to species from the western North Atlantic is presented. The species group containing Porogadus that lack well developed head spines and armature is partially revised on the basis of a study of specimens collected from the Atlantic and Pacific oceans. Of …

Observations On Structure And Evaluation Of Possible Functions Of The Vexillum In Larval Carapidae (Ophidiiformes), Jj Govoni, Je Olney, Df Markle, Wr Curtsinger

VIMS Articles

Elongate dorsal appendages adorn pelagic larvae of many fishes from disparate taxa, among them larvae of the family Carapidae, wherein the singular, elongate appendage is termed a vexillum, The vexillum is a complex larval specialization of the dorsal fin and is characteristic of all carapid genera, It is motile, well vascularized, and innervated by a branch of a cranial nerve with no apparent spinal innervation. Histological studies of Echiodon dawsoni and Carapus bermudensis vexilla show a two layered epidermis with mucous cells, an arteriole and venuole, two myelinated peripheral nerve fascicles, and two collagenous central shafts. No taste buds, free …

Model Studies On The Interactions Among Carbon Substrates, Bacteria And Consumers In A Salt-Marsh Estuary, Rl Wetzel, Rr Christian

VIMS Articles

We have developed a lagrangian computer simulation model to investigate the interactions between dissolved and particulate carbon-substrates of detrital (vascular plants) and phytoplankton origin, microbes attached and free-living in the water column, and consumers of these substrates for a specific estuarine water body: the Duplin River, Sapelo Island, Georgia. Model simulation experiments were directed toward investigating the potential for both carbon resource and heterotrophic grazing as controls on free-living and particle-attached bacterial densities. Given available information from the literature and our own work, we present simulations of the model that approximate what one generally finds in this estuary during summer …

Thermal Tolerance In Embryos And Larvae Of The Bay Scallop Argopecten Irradians Under Simulated Power Plant Entrainment Conditions, D. A. Wright, W. H. Roosenburg, M. Castagna

VIMS Articles

Thermal tolerance was tested in cleavage stages, trochophores and straight hinge larvae of the bay scallop Argopecten irradians. Experiments were designed to simulate larval entrainment in power plant cooling systems. An 11 (temperature) x 8 (time) matrix was used with temperatures ranging from 20.6 to 43.0 oc and exposure times from 1 min to 6 h. Pooled mortality data from triplicate experiments for each larval stage were subjected to stepwise regression analysis (Yarcsine % mortality on temperature and time). Equations derived from these analyses, comprising first, second and third order terms for temperature and time, were used to generate response …
