Book Description
The Impact of Dredging Operations on Suspended Material Transport in the Lower Thames River Estuary were confined to an area within 300 to 500 yards of the operating dredge and barge, produced an increase in total suspended load within the estuary that was small in comparison to that produced by typical aperiodic storm events, and caused no major alterations in mass transport within the estuary. Field surveys of the Thames River hydrography, phytoplankton, and trace metal concentrations in water, sediment and shellfish suggested that effects of dredging on primary production were spatially and temporally limited. The highest concentrations of nickel, lead, cadmium and mercury in water samples were observed before or during dredging, while copper was highest after dredging but were generally higher upriver. Sediment levels of these five metals, plus zinc and organic carbon, increased in an upriver direction. Dredging-related changes in trace metal body burdens in shellfish but were difficult to separate from normal seasonal variations. No gross pathology was detected in the shellfish. The physical oceanography of the disposal area showed that turbidity was higher in bottom waters than near the surface and was not restricted to the vecinity of the spoil pile. Maximum transport was in the east/west direction with highest values occurring during the ebbtide.

Book Description
It is also recommended that efforts be increased to farm lower trophic levels species and optimize feeds and feeding in order to minimize ecosystems impacts and ensure long-term sustainability. Similarly, risk assessments and/or environmental impact assessment and monitoring must always be in place before establishing offshore farms, and permanent environmental monitoring must be ensured. All coastal nations should be prepared to engage actively in developing the technological, legal and financial frameworks needed to support the future development of offshore mariculture to meet global food needs. The workshop report highlights the major opportunities and challenges for a sustainable mariculture industry to grow and further expand off the coast.
Multispecies Approaches to Fisheries Management Advice

Book Description
This publication comprises the proceedings of an international workshop convened in St. John's, Nfld, Nov. 26-29, 1979. The purpose of the workshop was to discuss the results of recent multispecies research, its applications to management, and to consider future directions for research in this field. A total of 26 papers were presented, including a combination of experience papers, state-of-the-art review, and new scientific findings. Sequential sessions were held on fisheries systems research by the Department of Fisheries and Oceans, multispecies considerations in fisheries research and management advice in the ICES area, species interactions in the Northeast Pacific and Northwest Atlantic, fisheries interactions, and applications to fisheries management. The workshop concluded with a substantial discussion of implications of present knowledge for advice to fisheries managers and implications for research program planning. The Workshop Report comprises the Chairman's opening remarks, a report on main elements of discussion in the sessions, and a summarization of workshop conclusions.
