What would the ultimate management system be?

Where are we now? What technologies are

available to move us forward?

“Fisherman’s Associate”

The map legend reports all the datavalues currently shown on the map.

Data ranges (shown as black, blueand red for low, medium, and high)can be adjusted to your preferencesfor both catch values and bathymetry.

Toolbar. A toolbar allowsyou to easily manipulate themap with the mouse. Pan,Zoom In, Zoom Out, andMap Query operations areimmediately available.

Map Operations. The user is ableadd or remove any map featurethrough the menu of operations. Inaddition to building maps, maps can bestored and retrieved for later analysis,or you can send your map to theprinter for a hard copy.

Cursor Positioning. TheLatitude and Longitude isconstantly displayed forwherever the cursor ispositioned.

Snags. Over 1,700 snags areavailable. These snags werecatalogued over the past 20 yearsby various fishermen. In addition,your own personal snags can beentered and added to any map.

Coastline. Each map contains abase-map of the coastline. Tworesolutions are available: lowresolution for large areas and highresolution for zooming in onsmaller areas (as shown).

Comprehensive On-Line Help. The on-linehelp provides you with a step-by-step descriptionof each map operation.

Also, a complete description of each of the 34species stored in Fisherman’s Associate isprovided for your perusal, including: range, lifemode, migrations and movements, populationcharacteristics, reproduction, growth anddevelopment, food and feeding, biologicalinteractions, factors influencing populations, andtheir distributions by depth during three points intheir life cycle.

Catch Statistics. Trawl survey statistics from 33commercially relevant species are included in a database that covers the years from 1980 to present.Catch values included in the database are: totalcount, female percentage, average weight, averagelength, average age, and catch per unit effort.

Catch plots can be made for any combination ofdays, months, and years, ranging from a single dayto all the years. Catch statistics are aggregated over2 minute by 2 minute cells and displayed as coloredtriangles. Two sets of catch statistics can bedisplayed on the map at any time. The upper triangleof the 2-by-2 cell represents catch one statistics, andthe lower triangle represents catch two statistics.

By comparing values from two species, it will bepossible to identify those areas with low bycatch aswell as those locations of the greatest value.

Zoom. You can zoom in on agiven region for a localperspective (shown above), orzoom out for a global view of thedata (shown here).

Bathymetry. Bathymetriccontours are available at fivedifferent intervals (1, 5, 10, 50,and 100 fm intervals). The depthrange (shown in legend to theright) tells us that this map isusing 10 fm intervals to a depth of200 fm. The depth for anindividual bathymetric line can bequeried with your mouse (asshown in the pop-up window onthe lower right).

Lat-Long Lines. Both 1 degreeand 15 minute lat-long lines withoptional labels.
