    Description: Despite an absence of freshwater exploitation, the adult salmon run in the Matamek River, Quebec, declined during 1975-1980 to 〈23% of the level thought to occur there prior to 1967. Returns in 1979 and 1980 of adults tagged as smolts were 1.0% and 0.9%, respectively. Numbers of emigrating smolts and their corresponding adult returns are not significantly correlated, although we observed a trend towards more salmon (2 sea year fish) returning with larger numbers of migrating smolts. Since 1967 there is noted a decrease in the age at which returning adults smolted and females appear to now constitute a larger percentage of returning grilse and salmon. These, and other changes in life history characteristics, appear to be caused solely by commercial exploitation.

    Description: A data storage and retrieval scheme has been designed and implemented which provides cost effective and easy access to location-dependent, 'geophysical' data. The system is operational on a Digital Equipment Corporation VAX-11/780 computer. Values of measured and computed geophysical parameters, such as geomagnetic field, water depth and gravity field, are stored in the library system. In addition, information about the data, such as port stops, project name and funding agency are also saved. These data are available to a time sharing computer user, validated to use the software package, through a query language designed to interact with this data library. The data can be searched and retrieved both sequentially and geographically.

    Description: A data storage format has been developed to be used for processed C.T.D. data on the Woods Hole Oceanographic Institution's Digital Equipment Corporation VAX 11 780 computer. CTDVAX as defined in this report is designed as a flexible internal data format. Station data is organized by ship-cruise-project using a VAX-supplied subdirectory system on disk. This report describes the data organization, file structures, and record formats. File naming conventions, data protection and documentation schemes are explained. Outlines are given of the data processing system in use and of the CTD data accessing utilities available on the VAX.

    Description: This report represents a first step at considering the potential for the use of market-based incentives to aid in the resolution of fishery bycatch problems. Market-based incentives have several advantages over more traditional command-and-control approaches, including cost-effective allocations of environmental controls; incentives for firms to seek technological solutions; flexibility; returns to the public for the use of its resources; and lower administrative costs in some cases. Notwithstanding these advantages and with several notable exceptions, market-based incentives are almost never employed in the management of fishery bycatch problems. There may be several reasons why this is the case, including significant distributional effects, high costs of monitoring and enforcement, difficulties in educating consumers about product attributes, administrative and transactions costs, or merely oversight. We consider this report to be an "advanced outline" of the issues surrounding the consideration of market-based incentives. We begin first by developing in Section 2 a definition of bycatch, including a "typology" of bycatch types. Next, we compile available public information on bycatch in U.S. fisheries, as defined by target species, location, and gear type (Section 3 and Appendix 1). We then review, in Section 4, two potentially relevant strands of literature, the economic theory of multispecies fisheries and studies from other social sciences of how small-scale fisheries deal with problems of bycatch. In Section 5, we describe, in general, the kinds of market-based policy instruments that may be of use in managing bycatch problems. Following this evaluation, we identify and discuss, as case studies; three priority fisheries: th~ northeastern groundfish fishery; the Gulf of Mexico shrimp fishery; and the eastern tropical Pacific yellowfin tuna fishery (Section 6). Finally, in Section 7, we outline approaches to identifying appropriate policy instruments, including a qualitative comparison of market-based approaches, an examination of the effect of specific types of uncertainty on the choice between taxes and ITQs, and the development of a "proposal" for a bycatch management "policy package." This section concludes with a proposal for a set of priority market-based approaches to bycatch management in the three cases discussed in Section 6.

    Description: The CAMS Interactive Atlas Package allows a user to computer contour any hydrographic quantity on any isosurface in any global projection. It consists of two parts: a large, and growing, data base which can be easily supplemented with user-supplied data, and a set of computer software routines that manage the data, interpolate onto the isosurface, and draw the maps. The data base presently includes the Levitus Climatological Atlas, IGY data, GEOSECs, TTO, and many NODC stations, all in a common format. In addition, the WHO! CTD data set can be easily accessed. This data base will be supplemented as new data becomes available. The software routines allow the user to interpolate the data vertically on to a selected isopleth, such as an isobaric or isopycnal surface, and then horizontally interpolate the station data onto a regular grid for final contouring. Land mass areas can be automatically blanked out. The continental boundaries are drawn in and the contouring done in any one of fifteen projections. Station locations, cruise tracks, and bottom topography can all be included. The contour map can be plotted on either a vector plotter or a raster device, allowing the use of color in the final product.
