    Description: Over the past four decades, the combination of in situ and remote sensing observations has demonstrated that long nonlinear internal solitary-like waves are ubiquitous features of coastal oceans. The following provides an overview of the properties of steady internal solitary waves and the transient processes of wave generation and evolution, primarily from the point of view of weakly nonlinear theory, of which the Korteweg-de Vries equation is the most frequently used example. However, the oceanographically important processes of wave instability and breaking, generally inaccessible with these models, are also discussed. Furthermore, observations often show strongly nonlinear waves whose properties can only be explained with fully nonlinear models.

    Description: First published online as a Review in Advance on October 24, 2005. (Some corrections may occur before final publication online and in print)
    Description: Author Posting. © Annual Reviews, 2005. This article is posted here by permission of Annual Reviews for personal use, not for redistribution. The definitive version was published in Annual Review of Physiology 68 (2006): 22.1-22.29, doi:10.1146/annurev.physiol.68.040104.105418.
    Description: Superfast muscles of vertebrates power sound production. The fastest, the swimbladder muscle of toadfish, generates mechanical power at frequencies in excess of 200 Hz. To operate at these frequencies, the speed of relaxation has had to increase approximately 50-fold. This increase is accomplished by modifications of three kinetic traits: (a) a fast calcium transient due to extremely high concentration of sarcoplasmic reticulum (SR)-Ca2+ pumps and parvalbumin, (b) fast off-rate of Ca2+ from troponin C due to an alteration in troponin, and (c) fast cross-bridge detachment rate constant (g, 50 times faster than that in rabbit fast-twitch muscle) due to an alteration in myosin. Although these three modifications permit swimbladder muscle to generate mechanical work at high frequencies (where locomotor muscles cannot), it comes with a cost: The high g causes a large reduction in attached force-generating cross-bridges, making the swimbladder incapable of powering low-frequency locomotory movements. Hence the locomotory and sound-producing muscles have mutually exclusive designs.
    Description: This work was made possible by support from NIH grants AR38404 and AR46125 as well as the University of Pennsylvania Research Foundation.

    Description: Following a brief account of the structure of the fishery sector in Bangladesh, an outline is given of fishery policy towards 2010. Before 1980, there was no statistical system for fisheries in Bangladesh. In the present system, fishery statistics are collected according to the survey manual. Catch assessment surveys for each of the 3 sectors (open-water, closed-water and marine) are undertaken; each of the surveys is designed as a sample of 1, 2, and 3 stage sampling for estimating total catches on the basis of data of sample units, which are collected by the Fishery Survey Officers. Details are given of proposals to improve the national fisheries statistics system.

    Description: The Korean fisheries is highlighted by a rapid increase in annual total production until 1990, but the trend has nearly leveled off in recent years. The total catch from coastal and offshore fishery maintained an increasing trend; while production from aquaculture has gradually increased, the inland water fishery has decreased, starting in 1980. The total population engaged in the fishery industry sector has decreased continuously every year. The production of fishery products in recent years has remained at a constant level. The total amount of import of fish and fishery products increased sharply in recent years while the exports did not vary. The Korean fishery industry has been facing serious difficulty not only due to the decrease of coastal and offshore fishery resources, but also the withdrawal of deep-sea fishing vessels from the coastal country's jurisdiction areas following the extension of 200 nautical miles EEZ. Some suggestions are given to overcome the present and future anticipated difficulties.

    Description: The vast area comprising the Indonesian archipelago means that the utilization of fishery resources has varied ways of implementation. Therefore, data collection for fishery statistical purposes has been designed considering these complex situations. An account is given of general trends in the Indonesian fishery sector, outlining the fishery policy towards 2010. The status of the national fishery statistical systems is described. For statistical purposes in Indonesia, fisheries are classified into the following sectors and sub-sectors: 1) Marine fishery -- capture/fishing, culture; and, 2) Inland fishery -- capture/fishing in open waters, culture in inland waters, brackishwater culture, freshwater pond culture, cage and pen culture, paddy-cum-fish culture. An examination is made of the problems and constraints in collecting fishery statistics, considering the 2 categories: technical or statistical; and, operational. Proposals are made for the improvement of national fishery statistical systems.

    Description: Following a brief account of the general trends currently observed in the fishery sector of the Philippines, a discussion is presented on the status of the National Fishery Statistical System. Fishery policy towards 2010 is also examined. It is concluded that fishery statistics in the Philippines are important due to the sector's sizable contribution to the national economy. Substantial funding support has been given to the Bureau of Agriculture Statistics to improve the methods of data generation, sampling designs and estimation procedures. The dissemination of fishery statistics has been enhanced with the creation of the Philippine Fisheries Information System at the Bureau of Fisheries and Aquatic Resources and the EASIBOARD of the Philippine Statistical Association. These systems will hopefully improve and accelerate data retrieval and information exchange among various fishery institutions and agencies.

    Description: The Myanmar Department of Fisheries, under the Ministry of Livestock Breeding and Fisheries, is responsible for the management of fisheries, conservation of resources, providing extension services, conducting research, and compilation of the national statistics in fisheries. Following a brief account of the types of fisheries in Myanmar, both marine and freshwater, an examination is made of fish production, licensed offshore fisheries (1996-1997), licensed inshore (1996-1997), export data, TCP/MYA/4553 Project and project activities (November 1995 to August 1997). The fishery sector is considerably important in the economy of the country, as fish constitutes a major source of animal protein in the diet of the people and is the 5th largest source of foreign exchange earnings. Fishery statistics are important in fishery management, and therefore the formulation and strengthening of fishery statistics survey is very useful for the fishery management of Myanmar.

    Description: A wide array of socio-economic data is needed for effective fishery management and development planning. Biological, technical, economic, social, and institutional information and data are required for sound management. How much information and routine, long-term data are essential and how reliable the data should be, has to be determined on a case by case basis. The type of data collected, their frequency, and the method of data acquisition vary greatly among countries with the varying importance of the fishery sector in the national economy. A brief account is given of the requirements and problems in data collection.

    Description: Fishery statistics have been successfully used to highlight increasing fishery production and contribution of fisheries to national economy. They are generally collected and compiled into national and regional yearbooks to demonstrate changes in fishery production from the previous year, or over a given period of time. An examination is made of regional cooperation for a fishery statistics programme, considering the Southeast Asia region and various issues and constraints in the compilation and utilization of fishery statistics. It has been shown that the basic functions of fishery statistics programmes are to provide data and information services for the sector management. Thus, regional cooperation in fishery statistics programmes must begin with identification of the sector management needs and determination of data requirements to address the needs identified. It is concluded that the region has made considerable progress in developing and establishing common data handling methodologies and tools. The existing regional standards include standard definitions and classifications of fish species, fishing gears and fish products used for compilation of statistics for the South China Sea Areas and FAO. Regional cooperation and collaboration ensure benefits of shared expertise and resources, and availability of comparable data for management and development of regional fisheries resources and industries.

    Description: The Arctic Ocean's Beaufort Gyre is a dominant feature of the Arctic system, a prominent indicator of climate change, and possibly a control factor for high-latitude climate. The state of knowledge of the wind-driven Beaufort Gyre is reviewed here, including its forcing, relationship to sea-ice cover, source waters, circulation, and energetics. Recent decades have seen pronounced change in all elements of the Beaufort Gyre system. Sea-ice losses have accompanied an intensification of the gyre circulation and increasing heat and freshwater content. Present understanding of these changes is evaluated, and time series of heat and freshwater content are updated to include the most recent observations.

    Description: Fishery statistics in Brunei Darussalam have been collected by the Department of Fisheries since the 1940s. In the early 1980s, a number of statistics were collected, such as catch and effort data of artisanal fishermen, aquaculture statistics, processing statistics as well as data from major wet markets focusing on the amount, prices of marketed fish either from the local fishermen or imported. In 1984, the collection of statistics on commercial fishing was started. The statistics have been used in the formulation of fishery management and development policies as well as for sectoral development. Following a brief account of the responsibility and statistic collections of the Department of Fisheries, an examination is made of employment in the fishery sector, fisheries production, fish marketed and the GDP for the fishery industry. Fisheries in Brunei Darussalam is a very healthy industry, where production is well below the maximum allowable harvestable limit of 20,000 tons at 30%. The Department is embarking to increase production from the capture fishery to reduce the country's dependence on imported fish; the same applies for aquaculture, in order to complement production from the capture fisheries. The processing sector is also increasing in importance, especially with the increase in the number of capture fishery licenses, and the demand for quality and value-added products.
