E-mail: [email protected] The poleward-flowing Kuroshio and the equatorward-flowing Oyashio are western boundary currents that transport heat, nutrients, and planktonic animals, including fish larvae from the subtropical/subarctic gyres, to the coastal areas of the Japanese archipelago. They converge east of Honshu Island to form an oceanographically complex Transition Zone that is an important area for the recruitment of some pelagic fishes of commercial interest. These species have developed life history traits and horizontal migration patterns by adapting to the seasonality of biological production and oceanography. Climatic and ecosystem regime shifts are key factors affecting the population dynamics of species in this region and need to be considered for the sustainable use of the region’s ecosystem services, including fish harvests. Proper understanding of how ecosystem dynamics are linked to both climate and human activities are essential for wise management, which recognizes ecosystem factors and various uncertainties. The most plausible mechanisms for sardine/anchovy cycles in the Kuroshio/Oyashio system are discussed to highlight the importance of these interconnections. Perspectives for sustainable use of ecosystem services, including fishing, will be discussed more generally in relation to case studies involving: 1) reclamation effects on a coastal ecosystem, 2) mitigation efforts, 3) successful adaptive co-management in a coastal fish stock, and 4) failure of fisheries management due to an overcapitalization that resulted from a mismatch between investment to fishing fleets and ecosystem regime shifts. iii PICES XV Abstracts Science Board Symposium S1 Boundary current ecosystems Co-Convenors: Kuh Kim (SB), Michael J. Dagg (BIO), Gordon H. Kruse (FIS), John E. Stein (MEQ) Michael G. Foreman (POC), Harold P. Batchelder (CCCC), Suam Kim (CCCC), Jeffrey M. Napp (MONITOR), Igor I. Shevchenko (TCODE), Fangli Qiao (China) and Yukimasa Ishida (Japan) The North Pacific is surrounded by boundary currents (e.g., Kuroshio, Tsushima, Oyashio, California, Alaska, Bering Slope) that support a diversity of ecosystems. These ecosystems are highly variable in space and time due to combinations of climate change, decadal “regime” shifts, ENSO and other interannual variability, seasonal and event mesoscale dynamics. This variability has led to dramatic changes at both low and high trophic levels, including productivity, range extensions, and species dominance. This theme will provide opportunities to address questions such as: 1) How will climate variation and projected climate change influence the dynamics and variability of boundary currents? 2) How will boundary current ecosystems respond to these physical property and transport changes? 3) How does human activity (e.g., fishing, hatcheries) alter the sensitivity of boundary current ecosystems to natural environmental forcing? and 4) What are appropriate management strategies to maintain healthy, sustainable living marine resources in boundary current systems that experience large environmental variations? Presentations that describe, compare and/or contrast physics, biology, fisheries, and geochemistry of boundary currents and the ecosystems they support are encouraged.

  • The Ulleung Eddy Owes Its Existence to Β and Nonlinearities
    The Ulleung eddy owes its existence to β and nonlinearities ∗ Wilton Z. Arruda a,1, Doron Nof a, ,2, James J. O’Brien b aDepartment of Oceanography 4320, The Florida State University, Tallahassee, FL 32306-4320, USA bCenter for Ocean Atmospheric Prediction Studies (COAPS), The Florida State University, Tallahassee, FL 32306-2840, USA Abstract A nonlinear theory for the generation of the Ulleung Warm Eddy (UWE) is pro- posed. Using the nonlinear reduced gravity (shallow water) equations, it is shown analytically that the eddy is established in order to balance the northward momen- tum flux exerted by the separating western boundary current. In this scenario the presence of β produces a southward (eddy) force balancing the northward momen- tum flux imparted by the separating East Korean Warm Current. 1/6 The solution is derived using an expansion in powers of (here = βRd/f0 where Rd is the Rossby radius based on the undisturbed upper layer thickness H). It is found that, for a high Rossby number western boundary current (i.e., highly 1/6 nonlinear current) the eddy radius is roughly 2Rd/ implying that the UWE has a scale larger than that of most eddies (Rd). This solution shows that, in contrast to the familiar idea attributing the formation of eddies to instabilities (i.e., the breakdown of a known steady solution), the UWE is an integral part of the steady stable solution. A reduced gravity numerical model is used to further analyze the relationship between β, nonlinearity and the eddy formation. First, we show that high Rossby number western boundary current which is forced to separate from the wall on an f-plane does not produce an eddy near the separation.

Abstract Background: Fishes in the families Cichlidae and Labridae provide good probable examples of vertebrate adaptive radiations. Their spectacular trophic radiations have been widely assumed to be due to structural key innovation in pharyngeal jaw apparatus (PJA), but this idea has never been tested based on a reliable phylogeny. For the first step of evaluating the hypothesis, we investigated the phylogenetic positions of the components of the suborder Labroidei (including Pomacentridae and Embiotocidae in addition to Cichlidae and Labridae) within the Percomorpha, the most diversified (> 15,000 spp) crown clade of teleosts.

  • Chapter 10 Adjacent Seas of the Pacific Ocean Although The
    Chapter 10 Adjacent seas of the Pacific Ocean Although the adjacent seas of the Pacific Ocean do not impact much on the hydrography of the oceanic basins, they cover a substantial part of its area and deserve separate discussion. All are located along the western rim of the Pacific Ocean. From the point of view of the global oceanic circulation, the most important adjacent sea is the region on either side of the equator between the islands of the Indonesian archipelago. This region is the only mediterranean sea of the Pacific Ocean and is called the Australasian Mediterranean Sea. Its influence on the hydrography of the world ocean is far greater in the Indian than in the Pacific Ocean, and a detailed discussion of this important sea is therefore postponed to Chapter 13. The remaining adjacent seas can be grouped into deep basins with and without large shelf areas, and shallow seas that form part of the continental shelf. The Japan, Coral and Tasman Seas are deep basins without large shelf areas. The circulation and hydrography of the Coral and Tasman Seas are closely related to the situation in the western South Pacific Ocean and were already covered in the last two chapters; so only the Japan Sea will be discussed here. The Bering Sea, the Sea of Okhotsk, and the South China Sea are also deep basins but include large shelf areas as well. The East China Sea and Yellow Sea are shallow, forming part of the continental shelf of Asia. Other continental shelf seas belonging to the Pacific Ocean are the Gulf of Thailand and the Java Sea in South-East Asia and the Timor and Arafura Seas with the Gulf of Carpentaria on the Australian shelf.

DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration National Marine Fisheries Service NOAA TECHNICAL REPORT NMFS The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic distribution of fishery resources, to understand and predict fluctuations in the quantity and distribution of these resources, and to establish levels for their optimum use. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis programs. and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the industry. The NOAA Technical Report NMFS series was established in 1983 to replace two subcategories of the Technical Reports series: "Special Scientific Report-Fisheries" and "Circular." The series contains the following types of reports: Scientific investigations that document long-term continuing programs of NMFS; intensive scientific reports on studies of restricted scope; papers on applied fishery problems; technical reports of general interest intended to aid conservation and management; reports that review in con­ siderable detail and at a high technical level certain broad areas of research; and technical papers originating in economics studies and from management investigations.

In the estimation of natural mortality, we considered growth rate and also reproduction rate, growth, and catch of sandfish, Arctoscopus japonicus. Assuming a linear relationship between observed values of the catch per unit effort (CPUE) and total biomass estimated by the age-structured biomass model, we estimated the age-specific natural mortality using the CPUE and catch data, from 1994 to 2009, for varying values of the assumed initial total biomass in 1994, by selecting the largest coefficient of determination (R2). We suggested the following empirical q K(i+1 t ) formula: M = ln e − 0 1 , which estimated natural mortality of sandfish, and the derived i KL K(i t0) − 1 e − 1 age-specific natural mortality− was significantly related to fecundity and growth.

  • Supplementary Information Doi: 10.1038/Nclimate1691
    SUPPLEMENTARY INFORMATION DOI: 10.1038/NCLIMATE1691 Shrinking of fishes exacerbates impacts of global ocean changes on marine ecosystems Supplementary information Method Dynamic Bioclimate Envelope Model (DBEM) As a first step, we predicted the current (19702000) distribution map of each species an algorithm described in [1,2]. This algorithm estimates the relative abundance of a species on a 30’ latitude x 30’ longitude grid of the world ocean. Input parameters for DBEM include the species’ maximum and minimum depth limits, northern and southern latitudinal range limits, an index of association to major habitat types (seamounts, estuaries, inshore, offshore, continental shelf, continental slope and the abyssal) and known occurrence boundaries. The parameter values of each species, which are posted on the Sea Around Us Project website (http://www.seaaroundus.org/distribution/search.aspx), were derived from data in online databases, mainly FishBase (www.fishbase.org). Jones et al. 3 compared the predicted species distribution from this algorithm with empirically observed occurrence records and found that the algorithm has high predictive power, and that its skills are comparable with other commonly used species distribution modelling approach for marine species such as Maxent4 and Aquamap5. As a second step, we used DBEM to identify the ‘environmental preference profiles’ of the studied species, defined by outputs from the Earth System Models, including sea water temperature (bottom and surface), depth, salinity, distance from seaice and habitat types. Preference profiles are defined as the suitability of each of these environmental conditions to each species, with suitability calculated by overlaying environmental data (19702000) with maps of relative abundance of the species 6.
