In the current context of natural resource management, marine protected areas (MPAs) are being widely propagated as an important tool for the conservation of marine and fisheries resources. The International Collective in Support of Fishworkers (ICSF) recently undertook a series of studies on MPAs in India to highlight the various legal, institutional, policy and livelihoods issues that confront fishing and coastal communities. In order to discuss the findings of these case studies and to suggest proposals for livelihood-sensitive conservation and management of coastal and fisheries resources through participatory processes, ICSF organized a two-day workshop on ‘Social Dimensions of Marine Protected Area Implementation in India: Do Fishing Communities Benefit?’ at Chennai on 21-22 January 2009. This publication—the India MPA Workshop Proceedings—contains the prospectus of the workshop, a report of the proceedings and the consensus statement that was reached by organizations and individuals who particapated in the workshop. This publication will be useful for fishworkers, non-governmental organizations, policymakers, trade unions, researchers and others interested in natural resource management and coastal and fishing communities.

Summary: This cruise report is a summary of a field survey conducted within the Stellwagen Bank National Marine Sanctuary (SBNMS), located between Cape Cod and Cape Ann at the mouth of Massachusetts Bay. The survey was conducted June 14 – June 21, 2008 on NOAA Ship NANCY FOSTER Cruise NF-08-09-CCEHBR. Multiple indicators of ecological condition and human dimensions were sampled synoptically at each of 30 stations throughout SBNMS using a random probabilistic sampling design. Samples were collected for the analysis of benthic community structure and composition; concentrations of chemical contaminants (metals, pesticides, PAHs, PCBs, PBDEs) in sediments and target demersal biota; nutrient and chlorophyll levels in the water column; and other basic habitat characteristics such as depth, salinity, temperature, dissolved oxygen, turbidity, pH, sediment grain size, and organic carbon content. In addition to the fish samples that were collected for analysis of chemical contaminants relative to human-health consumption limits, other human-dimension indicators were sampled as well including presence or absence of fishing gear, vessels, surface trash, marine mammals, and noxious sediment odors. The overall purpose of the survey was to collect data to assess the status of ecosystem condition and potential stressor impacts throughout SBNMS, based on these various indicators and corresponding management thresholds, and to provide this information as a baseline for determining how such conditions may be changing with time. While sample analysis is still ongoing a few preliminary results and observations are reported here. A final report will be completed once all data have been processed. The results are anticipated to be of value in supporting goals of the SBNMS and National Marine Sanctuary Program aimed at the characterization, protection, and management of sanctuary resources (pursuant to the National Marine Sanctuary Reauthorization Act) as well as a new priority of NCCOS and NOAA to apply Ecosystem Based approaches to the Management of coastal resources (EBM) through Integrated Ecosystem Assessments (IEAs) conducted in various coastal regions of the U.S. including the Northeast Atlantic continental shelf. This was a multi-disciplinary partnership effort made possible by scientists from the following organizations: NOAA, National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Environmental Health and Biomolecular Research (CCEHBR), Charleston, SC. U.S. Environmental Protection Agency (EPA), National Health and Environmental Effects Research Laboratory (NHEERL), Atlantic Ecology Division (GED), Narragansett, RI.

This cruise report is a summary of a field survey conducted in coastal-ocean waters of the Mid-Atlantic Bight from Nags Head, North Carolina to Cape Cod, Massachusetts and from approximately 1 nautical mile (nm) of shore seaward to the shelf break (100 m). The survey was conducted May 12 - May 21, 2006 on NOAA Ship NANCY FOSTER Cruise NF-06-06-NCCOS. Multiple indicators of ecological condition were sampled synoptically at each of 49 stations throughout the region using a random probabilistic sampling design. Samples were collected for the analysis of benthic community structure and composition; concentrations of chemical contaminants (metals, pesticides, PAHs, PCBs, PBDEs) in sediments and target demersal biota; nutrient and chlorophyll levels in the water column; and other basic habitat characteristics such as depth, salinity, temperature, dissolved oxygen, pH, sediment grain size, and organic carbon content. The overall purpose of the survey was to collect data to assess the status of ecological condition in coastal-ocean waters of the region, based on these various indicators, and to provide this information as a baseline for determining how environmental conditions may be changing with time. The results will be of value in helping to broaden our understanding of the status of ecological resources and their controlling factors, including impacts of potential ecosystem stressors, in such strategic coastal areas.

The United States and Japanese counterpart panels on aquaculture were formed in 1969 under the United States-Japan Cooperative Program in Natural Resources (UJNR). The panels currently include specialists drawn from the federal departments most concerned with aquaculture. Charged with exploring and developing bilateral cooperation, the panels have focused their efforts on exchanging information related to aquaculture which could be of benefit to both countries. The UJNR was begun during the Third Cabinet-Level Meeting of the Joint United States-Japan Committee on Trade and Economic Affairs in January 1964. In addition to aquaculture, current subjects in the program include desalination of seawater, toxic microorganisms, air pollution, energy, forage crops, national park management, mycoplasmosis, wind and seismic effects, protein resources, forestry, and several joint panels and committees in marine resources research, development, and utilization. Accomplishments include: Increased communication and cooperation among technical specialists; exchanges of information, data, and research findings; annual meetings of the panels, a policy-coordinative body; administrative staff meetings; exchanges of equipment, materials, and samples; several major technical conferences; and beneficial effects on international relations.

The trawl fishery for pelagic annorhead, Pseuaopentaceros wheeleri(fonnerly referred to as Pentaceros richardsoni), and alfonsin, Beryx splendens, over the central North Pacific seamounts has a relatively short history. Before 1967, fishery scientists were generally unaware of the resources on seamounts; however, the discovery of commercial concentrations of pelagic armorhead on seamounts in the southern Emperor Seamounts by a Russian commercial trawler in November 1967 led to almost immediate exploitation of the species by the Soviets. Unconfinned reports indicated that the schools of pelagic annorhead on the seamounts averaged 30 m thick and catches averaged from 3 to 50 metric tons on 10-20 min hauls (Sakiura 1972). Japanese trawlers entered the fishery in 1969. To assist in the development of this tishery, Japanese research vessels conducted extensive surveys in 1972 on the distribution and potential for development ofthe pelagic armorhead and alfonsin resources. The results of their surveys to the central North Pacific and mid-Pacific seamounts showed that many had summits that were too deep for trawling. Those found suitable were concentrated in the southern Emperor-northern Hawaiian Ridge. (PDF file contains 113 pages.)

The 23rd Annual Symposium on Sea Turtle Biology and Conservation was held between 17 and 21 March 2003 at The Legend Hotel in Kuala Lumpur, Malaysia, hosted by the Community Conservation Network, Hawaii, and WWF-Malaysia. The meeting was attended by slightly more than 300 participants representing 73 countries, a dramatic drop in participation from previous years brought about in no small part by the looming war in the middle east region and concerns over travel safety. For 22 years the Symposium had bee an Americas-based event, even though it is the annual gathering of the "international" sea turtle society, and with the move to Malaysia, the Symposium hoped to raise the awareness among the general public of the plight of amrine turtles in Southeast Asia, and share the enormous exspertise of the world authorities on sea turtles with this so-far underrepresented region. Adopting the thems, "Living With Turtles", the Symposium had a very personal flavour, and the smaller number of participants made it possible to make and renew acquaintances, and have time for discussion between sessions. While the travel safety concern excuse was often quoted, it was a pity, particularly to the large contingent of people who attended the event for the first time from underrepresented regions, that many of the household names linked to marine turtle biology and conservation were not present to share their knowledge and promote the global concerns on the plight of turtle populations.

ENGLISH: All available longline data on skipjack captured in the Pacific Ocean by Japanese research vessels (1949-1965) and from incidental skipjack catches by Japanese commercial vessels (1956-1964) were analyzed. As skipjack are not specifically sought by longline vessels, the data are limited. Considering this it was found that: longline gear captures skipjack of wider size-range and is more selective for larger skipjack than conventional fishing methods, i.e. pole-and-line and purse-seine; skipjack are widely and almost continuously distributed across the Pacific; throughout the year average hook-rates are greater in the southeastern Pacific than in the northwestern Pacific; areas of high hook-rate shift south during the second and third quarters and north during the first and fourth quarters; in the western Pacific the north-south range of the catch distribution was greatest in the first and fourth quarters; skipjack hook-rates are relatively high in the northwestern Pacific east of Japan only during the first and fourth quarters; the highest hook-rates were recorded in extensive areas along the equator (from lO°N to 20°8 between approximately 155°W-100°W); generally more skipjack were captured by research longline gear in water temperature ranges approaching both the upper and lower temperature limits of skipjack distribution (18-21C and 26-28C), than is the case in surface skipjack fisheries; tentative comparisons of longline skipjack catch distributions with Pacific current systems, suggests low skipjack abundance in both North Pacific Central and North Pacific Equatorial water; the sex ratio was 95 males : 63 females in a small sample of skipjack examined; longlines capture skipjack of three, and possibly more, age groups; in skipjack size-composition samples studied, the smaller modal group (65 cm) observed in January-March in the northwestern Pacific (1600E-180oE and 20oN-45°N) corresponds in size to the larger modal group appearing in the late-summer surface fishery off the Izu-Bonin Islands southeast of Japan, and also compares in modal size to the skipjack taken in the Hawaiian fishery in spring time; the analysis of skipjack catches by hook position on the longline and by death-rate studies, indicates that part of the catch is made while the gear is in motion near the surface, and a lesser part of the catch is made when the gear is stabilized at a depth of 70 to 140 m. A brief discussion is given, in the light of new information presented, on several hypotheses by other authors concerning the population structure and migration of skipjack in the Pacific Ocean. SPANISH: Se analizaron todos los datos disponibles de la pesca con palangre de barriletes capturados en el Océano Pacífico por barcos japoneses de investigación (1949-1965) y por las capturas incidentales de los barcos comerciales japoneses (1956-1964). Como los barcos palangreros específicamente, no persiguen al barrilete, los datos son limitados. Considerando ésto, se encontró: que el arte palangrero obtiene barriletes con una distribución más amplia de tallas, y es más selectivo en cuanto a los barriletes de mayor talla, que los métodos convencionales de pesca, Le. cañas de pescar y redes de cerco; el barrilete se encuentra amplia y casi continuamente distribuido a través del Pacífico; en todo el año, las tasas promedio de captura por anzuelo son superiores en el Pacífico sudoriental que las del Pacífico noroeste; las áreas con una tasa alta de captura por anzuelo, se cambian hacia el sur durante los trimestres segundo y tercero, y durante los trimestres primero y cuarto hacia el norte; en el Pacífico occidental la amplitud de la distribución de captura norte-sur, fue superior en los trimestres primero y cuarto; las tasas de captura por anzuelo de barrilete, son relativamente altas en el Pacífico noroeste al este del Japón, únicamente durante los trimestres primero y cuarto; las tasas de captura por anzuelo más altas fueron registradas en extensas áreas a lo largo del ecuador (desde los 10°N hasta los 20°S, aproximadamente entre los 155°W-100°W) ; generalmente las artes palangreras de investigación capturaron más barrilete en aguas en las que la temperatura se aproximaba a los límites más altos o bajos de la temperatura en la distribución del barrilete (18-21 C y 26-28 C), que en el caso de la pesca superficial de barrilete; las comparaciones tentativas de la captura de barrilete con palangre, con el sistema de las corrientes del Pacífico, sugieren una abundancia inferior de barrilete tanto en las aguas del Pacífico central del norte como en las del Pacífico ecuatorial del norte; la proporcíon sexual examinada en una pequeña muestra de barriletes, fue de 95 machos y 63 hembras; los palangreros capturan barriletes de tres grupos de edad y posiblemente de más; en las muestras estudiadas de la composición de las tallas de barrilete, el grupo modal más pequeño (65 cm), observado en enero-marzo en el Pacífico noroeste (160 0E-180° y 20 oN-45°N), corresponde en talla al grupo modal más grande que aparece en la pesca de superficie a fines del verano frente a las Islas Izu-Bonín al sudeste del Japón, y se compara también con la talla modal del barrilete obtenido en la pesca hawaiana en la época de primavera; el análisis de las capturas de barrilete por medio del estudio de la posición de los anzuelos en el palangre y por la tasa de mortalidad, indica que parte de la captura se efectúa cuando el equipo está en movimiento cerca a la superficie y una parte inferior de la captura se realiza, cuando las artes se estabilizan a una profundidad de 70 a 140 m. Se ofrece una breve discusión sobre varias hipótesis de otros autores, en vista de la nueva información presentada referente a la estructura poblacional y a la migración del barrilete en el Océano Pacífico.

The Alliance for Coastal Technologies (ACT) convened a workshop on Evaluating Approaches and Technologies for Monitoring Organic Contaminants in the Aquatic Environment in Ann Arbor, MI on July 21-23, 2006. The primary objectives of this workshop were to: 1) identify the priority management information needs relative to organic contaminant loading; 2) explore the most appropriate approaches to estimating mass loading; and 3) evaluate the current status of the sensor technology. To meet these objectives, a mixture of leading research scientists, resource managers, and industry representatives were brought together for a focused two-day workshop. The workshop featured four plenary talks followed by breakout sessions in which arranged groups of participants where charged to respond to a series of focused discussion questions. At present, there are major concerns about the inadequacies in approaches and technologies for quantifying mass emissions and detection of organic contaminants for protecting municipal water supplies and receiving waters. Managers use estimates of land-based contaminant loadings to rivers, lakes, and oceans to assess relative risk among various contaminant sources, determine compliance with regulatory standards, and define progress in source reduction. However, accurately quantifying contaminant loading remains a major challenge. Loading occurs over a range of hydrologic conditions, requiring measurement technologies that can accommodate a broad range of ambient conditions. In addition, in situ chemical sensors that provide a means for acquiring continuous concentration measurements are still under development, particularly for organic contaminants that typically occur at low concentrations. Better approaches and strategies for estimating contaminant loading, including evaluations of both sampling design and sensor technologies, need to be identified. The following general recommendations were made in an effort to advance future organic contaminant monitoring: 1. Improve the understanding of material balance in aquatic systems and the relationship between potential surrogate measures (e.g., DOC, chlorophyll, particle size distribution) and target constituents. 2. Develop continuous real-time sensors to be used by managers as screening measures and triggers for more intensive monitoring. 3. Pursue surrogate measures and indicators of organic pollutant contamination, such as CDOM, turbidity, or non-equilibrium partitioning. 4. Develop continuous field-deployable sensors for PCBs, PAHs, pyrethroids, and emerging contaminants of concern and develop strategies that couple sampling approaches with tools that incorporate sensor synergy (i.e., measure appropriate surrogates along with the dissolved organics to allow full mass emission estimation).[PDF contains 20 pages]

The co-organized Alliance for Coastal Technologies (ACT) and National Data Buoy Center (NDBC) Workshop "Meteorological Buoy Sensors Workshop" convened in Solomons, Maryland, April 19 to 21,2006, sponsored by the University of Maryland Center for Environmental Science (UMCES) Chesapeake Bay Laboratory (CBL), an ACT partner institution. Participants from various sectors including resource managers and industry representatives collaborated to focus on technologies and sensors that measure the near surface variables of wind speed and direction, barometric pressure, humidity and air temperature. The vendor list was accordingly targeted at companies that produced these types of sensors. The managers represented a cross section of federal, regional and academic marine observing interests from around the country. Workshop discussions focused on the challenges associated with making marine meteorological observations in general and problems that were specific to a particular variable. Discussions also explored methods to mitigate these challenges through the adoption of best practices, improved technologies and increased standardization. Some of the key workshop outcomes and recommendations included: 0cean.US should establish a committee devoted to observations. The committee would have a key role in developing observing standards. The community should adopt the target cost, reliability and performance standards drafted for a typical meteorological package to be used by a regional observing system. A forum should be established to allow users and manufacturers to share best practices for the employment of marine meteorological sensors. The ACT website would host the forum. Federal activities that evaluate meteorological sensors should make their results publicly available. ACT should extend their evaluation process to include meteorological sensors. A follow on workshop should be conducted that covers the observing of meteorological variables not addressed by this workshop. (pdf contains 18 pages)
