Although these viruses pose no threat to human health, outbreaks on U.S. shrimp farms, the appearance of diseased shrimp in U.S. commerce, and new information on the susceptibility of shrimp and other crustaceans to these viruses prompted calls for action. In response, the Joint Subcommittee on Aquaculture (JSA) tasked a Federal interagency Shrimp Virus Workgroup with assessing the shrimp virus problem. Four Federal agencies are represented on the JSA Shrimp Virus Workgroup: the National Marine Fisheries Service (NMFS), the Animal and Plant Health Inspection Service (APHIS), the Environmental Protection Agency (EPA), and the Fish and Wildlife Service (FWS). In June 1997, the Shrimp Virus Workgroup summarized the available information on shrimp viruses in a report to the JSA entitled "An Evaluation of Potential Shrimp Virus Impacts on Cultured Shrimp and on Wild Shirmp Populations in the Gulf of Mexico and Southeastern U.S. Atlantic Coastal Waters" (JSA Shrimp Virus Report [JSVR]). During July 1997, in cooperation with the JSA, EPA's National Center for Environmental Assessment (NCEA) sponsored a series of four stakeholder meetings to gather stakeholder input on the JSVR and the shrimp virus issue. The JSVR and the stakeholder (public) comments formed the basis for the shrimp virus peer review and risk assessment workshop, held during January 1998. Workshop participants considered several potential pathways of nonindigenous pathogenic shrimp viruses to wild shrimp populations, including shrimp aquaculture, shrimp processing, and "other" sources and pathways, and independently assessed risks using a qualitative risk assessment approached developed by the Aquatic Nuisance Species Task Force. The workshop report was revised based on comments provided by an external scientific review in July 1998. This workshop report, together with the results of the independent scientific review, was used as the basis for a risk management workshop on shrimp viruses held on July 28-29, 1998, in New Orleans. The risk management workshop, jointly sponsored by the EPA Gulf of Mexico Program, NMFS, and the USDA Agricultureal Research Service, developed options and strategies for managing the threat of shrimp viruses to cultured and wild stocks of shrimp in the Gulf fo Mexico and southeastern U.S. Atlantic coastal waters.Item Proceedings: the State of the Bay Symposium V. January 31 - February 02, 2001.(Texas Natural Resource Conservation Commission, 2001) Galveston Bay Estuary Program; Palmer, Cathy L.P., Jonathan L.Klamberg, Steward J. Schultz, and Scott A. JonesThe State of the Bay Symposium is hosted biennially to provide and opportunity for resource managers, scientists, industries, regualtors, policy-makers, and the public to interact and share information. This year 2001, with the theme Galveston Bay: Past, Present, and Future, will include information on the status and trends of key indicators which depict the health of our bay, the significance of a changing watershed in the preservation of the bay, and the importance of partnerships in restoration and protection of the bay. Summarizing some of the current data and trends, a Galveston Bay Characterization Highlights document is also being released. (See Acc# 9192). This document provides new information to update the State of the Bay, a characterization document released in 1994 (See Acc# 8274) as the scientific foundation for the development of The Plan. (See Acc# 8372). This characterization document will highlight updates of the status of key habitats, living resources, and water quality in Galveston Bay.Item Western Atlantic Shrimps of the Genus Penaeus(U.S. Fish and Wildlife Service, 1969) Isabel Perez Farfante; U.S. Fish and Wildlife Service Fishery BulletinFour subgenera of the genus Penaeus are described (Litopenaeus, Penaeus s.s., Fenneropenaeus, and Melicertus). Eight species and subspecies (P. setiferus, P. schmitti, P. duorarum notialis, P. aztecus aztecus, P. aztecus subtilis, P. paulensis, and P. brasiliensis) are recognized as occurring in the western Atlantic. Synonymies are given. Lectotypes have been designated for two species, and the disposition of all types is shown. Diagnoses, detailed descriptions, and illustrations are presented for each species and subspecies. Geographic and bathymetric distributions are given. Affinities are discussed, and conclusions concerning ranges of variation and their spatial distributions are based on morphometric studies and other characters. The development of the external genitalia through the juvenile stage and the size range at which each taxon reaches the subadult stage are presented. Many details of ecology and life history are critically summarized and reviewed. A brief appraisal of the commercial importance of each form is also given.Item Trinity - San Jacinto estuary: A study of the influence of freshwater inflows(Texas Department of Water Resources, 1981) Texas Department of Water ResourcesThe provision of sufficient freshwater inflow to Texas bays and estuaries is a vital factor in maintaining estuarine productivity, and a factor contributing to the near-shore fisheries productivity of the Gulf of Mexico. This report analyzes the interrelationships between freshwater inflows and estuarine productivity, and established the seasonal and monthly freshwater inflow needs, for a range of alternative management policies, for the Trinity- San Jacinto estuary of Texas. Simplifying assumptions must be made in order to estimate freshwater inflow requirements necessary to maintain Texas estuarine ecosystems. A basic premise developed in this report is that freshwater inflow and estuarine productivity can be examined through analysis of certain key indicators. The key physical and chemical indicators include freshwater inflows, circulation and salinity patterns, and nutrients. Biological indicators of estuarine productivity include selected commercially important species. Useful species are generally chosen on the basis of their wide distribution throughout each estuarine system, a sensitivity to change in the system, and an appropriate life cycle to facilitate association of the organism with estuarine productivity.Item Managing Nonpoint Source Pollution(United States Environmental Protection Agency, 1992-01) United States Environmental Protection Agency Office of WaterThis report focuses on the state of the national effort to control nonpoint source pollution as of October 1, 1989. Included are the findings of the state nonpoint source assessments; state programs for addressing problems identified in the assessments; related activities of EPA, other federal agencies, and others; and achievements to date on controlling nonpoint source pollution. This report does not discuss implementation activities funded with Fiscal Year 1990 grants and thus may understate the current level of state nonpoint source control activities.Item Study of the Texas Bay Populations of Juvenile Shrimp, Penaeus aztecus, Penaeus setiferus, and Penaeus duorarum - Study of the Texas Shrimp Population(Texas Parks and Wildlife Department, 1965) Moffett, Alan W.; Texas Parks & Wildlife Coastal Fisheries Project Reports 1964Plankton samples from the Aransas Bay area indicated that the postlarvae brown shrimp (Penaeus aztecus) immigration peak was reached in March. Sampling in the bays revealed the presence of a large wave of brown shrimp in the spring. In the shallow tertiary bays and along the shore of large bays brown shrimp grew slowly in April and movement to the open water of larger bays was delayed. As the waters warmed growth was rapid and the shrimp began their gulfward movement on schedule. Samples taken in the inshore Gulf off the Lower Laguna Madre contained large numbers of brown shrimp in May. The samples from the Gulf off Port Aransas indicated that the majority of this species left the Aransas Bay area in June. Shrimp samples from the bays indicated the presence of a large 1964 white shrimp year class. This was confirmed by large commercial catches in the late summer and early fall. Small white shrimp were found in the Gulf in September off the lower coast. In January this species was found in abundance off Port Aransas, but not off Galveston. Brown shrimp commercial landings were somewhat disappointing, however, white shrimp landings were greater than landings reported in 1963.Item Importance of Seafood-Linked Employment and Payroll in Texas(Sea Grant Program, Texas A&M University, 1993) Haby, MG; Edwards, RA; Reisinger, EA; Tillman, RE; Younger, WRThis report quantifies seafood-linked employment and payroll beginning with those firms supplying commercial fishing enterprises and ending with retail interests.Item Method for Quantifying Environmental Indicators of Selected Leisure Activities in the United States(United States Environmental Protection Agency, 2000-12) United States Environmental Protection Agency Office of Policy, Economics, and InnovationEPA is pleased to present this study, the first of its kind to develop environmental indicators for the many industries that comprise the tourism and recreation sector. Historically, EPA has not focused a great deal of its effort either on the service sector or on tourism and recreation industries. This report establishes a foundation of knowledge with the hope of promoting constructive dialogue and innovative solutions to advance environmentally sustainable travel, tourism, and recreation.Item Subsurface Flow Constructed Wetlands for Wastewater Treatment - A Technology Assessment(United States Environmental Protection Agency, 1993-07) United States Environmental Protection Agency Office of WaterIt is the intent of this report to present current (1993) information and guidance on design, construction, performance, operation and maintenance of subsurface flow constructed wetlands used for treatment of domestic and municipal wastewaters. Subsurface flow constructed wetlands are in relatively common use in Europe, Australia, and in a number of states in the United States. However, there has been no apparent consensus on design procedures or performance expectations. A two-step procedure was used for the preparation of this report to develop a consensus among knowledgeable experts.Item Groundfish Industries of New England and Canada - A Comparative Economic Analysis(United States Department of the Interior Fish and Wildlife Service Bureau of Commercial Fisheries, 1961-07) Lynch, Edward J.; Doherty, Richard M.; Draheim, George P.The American groundfish industry, centered in New England, far from participating in the general prosperity which has characterized the national economy in the post-World War II period, has been in a continual stage of decline during these years. The growing unprofitability of the groundfish industry and its effects on new investment, employment, and vessel construction, are matters of grave concern not only to those whose livelihood depends on the industry, but also to those concerned with the preservation, development, and utilization of the fishery in an area notably short of resource - based enterprises. The major reasons usually assigned for this decline are the decline of fish populations in local waters to lower but stable levels and the consequent high unit costs of operating, the costs and difficulties of marketing the product in competition with other food items, and the impact of foreign competition, principally from the Canadian Atlantic Provinces. This report is an attempt to qualify and quantify these and other causes, both internal and external, of the decline of the New England groundfish industry. In doing so, it will focus on the comparative performances of the industries of New and its chief competitor, the Canadian Atlantic Provinces. It deals with the economic, social, and biological factors which have affected both.Item Status Report on the Water and Wastewater Infrastructure Program for the U.S.-Mexico Borderlands(United States Environmental Protection Agency, 2000-05) United States Environmental Protection Agency Office of WaterIn the Mexican Border region, pollutants from both countries are entering shared waterways due to inadequately treated sewage. This, along with inadequately treated drinking water, is impacting the health of border residents as well as degrading environmental quality. The United States and Mexico have developed a cooperative program along the international boundary to address these issues. Through the success of cooperative efforts between the U.S. Environmental Protection Agency's Office of Water, the National Water Commission of Mexico, the binational International Boundary and Water Commission, the Border Environmentl Cooperation Commission and the North American Development Bank, much has been accomplished along both sides of the border. However, much remains to be done in order to ensure a safe and healthy environment for those living in the border area that depend on its water resources. This status report explores the remaining needs and identifies what has been accomplished. No one organization can achieve the results needed in this binational environment, but EPA is proud to be a member of the team that has created a positive cooperative effort and has demonstrated results. The Agency anticipates continuing to participate in these joint efforts in order to achieve its mission and fulfull its responsibilities to the people of the border area.Item Bio-assay and Chemical Analysis of Atlantic Refining Company's Waste Waters, Port Arthur Plant - Industrial Waste Control in Region MP-1(Texas Game and Fish Commission, 1960-01-31) Marek, R., Jr.Objectives: (1) To determine the toxic effects of wastes on marine life; (2) Check for toxic compounds in waste waters; (3) Improve quality of waste waters.Item Annual Report Exploratory Fishing and Gear Research Bureau of Commercial Fisheries Region 2 For Fiscal Year 1965(United States Department of the Interior Fish and Wildlife Service Bureau of Commercial Fisheries, 1966-10) United States Department of the Interior Fish and Wildlife Service Bureau of Commercial FisheriesNo abstract available.Item Hydrographic and climatological data - Oyster Investigations(Texas Game and Fish Commission Marine Laboratory, 1961) Shidler, Jon K.; Texas Game and Fish Commission Marine Fisheries Project Reports 1960-1961Objectives: To maintain records of hydrographic and climatological data as an aid in evaluating changes in bay fauna. To summarize these records in a form which makes their interpretation as components of the biotic environment more convenient.Item Water Quality Standards Handbook: Second Edition(United States Environmental Protection Agency, 1994-08) United States Environmental Protection Agency Office of WaterThe following document entitled "Water Quality Standards Handbook - Second Edition" provides guidance issued in support of the Water Quality Standards Regulation (40 CFR 131, as amended). This Handbook includes the operative provisions of the first volume of the Handbook issued in 1983 and incorporates subsequent guidance issued since 1983. The 1993 Handbook contains only final guidance previously issued by EPA - it contains no new guidance. Since the 1983 Handbook has not been updated in ten years, we hope that this edition will prove valuable by pulling together current program guidance and providing a coherent document as a foundation for State and Tribal water quality standards programs. The Handbook also presents some of the evolving program concepts designed to reduce human and ecological risks, such as endangered species protection; criteria to protect wildlife, wetlands, and sediment quality; biological criteria to better define desired biological communities in aquatic ecosystems; and nutrient criteria. This Handbook is intended to serve as a "living document," subject to future revisions as the water quality standards program moves forward, and to reflect the needs and experiences of EPA and the States. To this end, the Handbook is published in a loose leaf format designed to be placed in three ring binders. This copy of the Handbook includes updated material for 1994 (see Appendix X), and EPA anticipates publishing additional changes periodically and providing them to Handbook recipients. To ensure that you will receive these updates, please copy the reader response card in Appendix W and mail it to the address on the reverse. The Handbook also contains a listing, by title and date, of the guidance issued since the Handbook was first published in 1983 that is incorporated in the Second Edition. The "Water Quality Standards Handbook - Second Edition" provides guidance on the national water quality standards program. EPA regional offices and States may have additional guidance that provides more detail on selected topics of regional interest. For informaion on regional or State guidance, contact the appropriate regional water quality standards coordinator listed in Appendix U.Item Population Studies of the Blue Crabs of the Upper Laguna Madre - Studies of the Blue Crab Populations of the Texas Coast(Texas Parks and Wildlife Department, 1965) Hawley, William C.All blue crabs contained in the samples were taken in areas where the salinity was under 50 ppt. It was concluded that the lagoon was too salty for blue crabs in 1964.Item Dredge and fill activities in Galveston Bay(Galveston Bay National Estuary Program, 1993) Ward, George H.The objective of this study is to quantitatively characterize dredge and fill activities throughout the bay as a function of time. This required compilation and processing of several categories of historical data. This report provides an interpretive summary, and the compiled data comprise a centralized information base for further specific studies of associated biochemecal impacts of dredging and sediment placement.Item Inventory of the Bottom Sediment Types Present in Area M-6(Texas Game and Fish Commission, 1959) Heffernan, Thomas L.Objective: To determine the bottom composition of the area and to chart the bottom sediments as a guide for possible location of proposed artificial reefs or reef expansion.
