Available in PDF, EPUB and Kindle. Book excerpt: A 3-year laboratory study identified certain estuarine fish sensitive to the effects of particle size and concentration of (a) suspended mineral solids similar in size to sediments likely to be found in estuarine systems in concentrations typically found during flooding, dredging, and disposal of dredged material, and (b) natural sediments in identical experiments. Significant mortality of estuarine fish was demonstrated at these suspended mineral solid concentrations. Estuarine fish were classified, using static bioassays as: Tolerant (24-hour LC10 greater than or equal to 10 grams per liter), sensitive (10 grams per liter greater than 24-hour LC 10 greater than 1.0 gram per liter), or highly sensitive (24-hour LC10 greater than or equal to 1.0 gram per liter) to fuller's earth suspensions. Generally, bottom-dwelling fish species were most tolerant to suspended solids; filter feeders were most sensitive. Early life stages were more sensitive to suspended solids than adults; filter feeders were most sensitive. Bioassays with natural sediments indicated that suspensions of natural muds affected fish in the same way as fuller's earth, but higher concentrations of natural material were required to produce the same level of response. The effect of finely divided solids on fish was dependent on concentration, particle-size distribution, and angularity of the suspended particles. The cause of death was the same in all experiments--anoxia. This study provides base-line information for preproject decisionmaking based upon the anticipated concentration of suspended sediments at the project site and the effect of various lengths of exposure on estuarine fish of different life-history stages and habitat preference.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to determine the effects, if any, of sublethal concentrations of suspended materials on the fish in estuarine systems. Experimental sediment suspensions reproduced the concentrations frequently found during flooding and at dredging sites and dredged-material disposal sites. The suspensions were of natural sediment, obtained from the Patuxent River estuary, Maryland, or commercially available Fuller's earth. Fish were collected in the Patuxent River estuary and transported to the laboratory. The selected fish species inhabited ecologically different sections of the estuary; therefore, the overall reactions of each species were unique. Seven species of estuarine fish were exposed to Fuller's earth and natural sediment suspensions for timed periods and hematological changes were noted. The effects of various concentrations of Fuller's earth suspensions on white perch gill tissue were determined. Oxygen consumption rates of striped bass, white perch, and toadfish were measured in filtered Patuxent River water and compared to consumption rates in filtered river water suspensions of Fuller's earth or Patuxent River sediment. Fish showed signs of stress in response to suspended sediments in most of the experiments. Results indicate that sublethal concentrations of suspended solids can affect estuarine fish.

Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together a cross-section of marine experts who provide a comprehensive exploration of the major facets of Asia's marine sector. It considers both the marine mineral and fish stocks in Asian waters. This extensive volume examines "official" statistics with an objective eye and provides an overview of fish stock with much focus on the access and management of tuna. It considers global economic issues concerning fishing rights, looks at joint ventures between nations, and considers law enforcement efforts. The volume devotes a section to sea lanes and another to off shore mineral deposits. It also considers current and growing problems and possible solutions regarding pollution.
