Catch Rate by Minor Bay Help and
Frequently Asked Questions (FAQ)

What does this application do? How is catch rate data displayed?
This application can be used to display the catch rates of several important fish species in Texas coastal waters by year for either a species of interest or for a bay of interest. Minor bays, boat ramps and roads are also displayed.

Catch rates are classified into ‘high’, ‘medium’ or ‘low’ based on their historical values. High catch rates are those in the upper 25th percentile observed for that species, medium catch rates are in the middle 50th percentile, and low catch rates are those in the lower 25th percentile.

Where can I get more information on this application or what if I have questions regarding the data and content of this site?
Information about the content of this application or other content questions will be addressed by Texas Parks & Wildlife Coastal Fisheries staff. [back to top of page]

If I am interested in a particular fish species, how do I determine which bays have the best catch rates?
First, click the Year tab if it is not already active and select a year by clicking on it in the list of years. Next, click the Species tab and a list of available fish species will appear. Next, select your species of interest, click and a ‘Catch Rate Bay Report’ will be generated and appear.

The Catch Rate Bay Report will have each bay listed on the left side of the screen with a box next to it displaying red for a high catch rate, orange for a medium catch rate and yellow for a low catch rate. Bays on the list are sorted first by high, medium and low catch rate and alphabetically within each catch rate. The map on the right side of the screen shows each of the bays colored with red, orange or yellow to reflect the high, medium and low catch rates respectively. [back to top of page]

If I am interested in a particular bay, how do I determine which fish species have the best catch rates?
First, click the Year tab if it is not already active and select a year by clicking on it in the list.  Next, click the Bays tab and a list of available bays will appear. Click on your bay of interest and a ‘Species Catch Rate Report’ will be generated and appear.

The Species Catch Rate Report will have each species listed on the left side of the screen with a box next to it displaying red for a high catch rate, orange for a medium catch rate and yellow for a low catch rate. The species are listed in alphabetical order. [back to top of page]

How do I find out more information about a fish?
You can use links on each type of report to find out more information about a fish. On the title of the Catch Rate Bay Report, the fish name is linked to a species web page on the site. On the Species Catch Rate Report, each species listed on the left side of the screen is linked to the same web page. This species page has an image of the fish along with description, history, habitat and distribution information. [back to top of page]

How do I find out more information about a bay?
The best way to find out more information from this application is to zoom into your bay of interest. Zooming in will show you show you which roads lead to that bay, what cities are nearby and whether there are any boat ramps.

Select a year from the Year tab. Click the Bay Report button at the top of the map, move cursor to a bay and left mouse click to get the ‘Species Catch Rate Report’ for that bay. This button also allows you to click on adjacent bays to get additional information. [back to top of page]

How do I zoom in to a bay?
There are several different ways to zoom in to a bay. On the ‘Catch Rate Bay Report,’ each bay listed is linked and a click on the link will zoom in to that bay. On the title of the ‘Species Catch Rate Report’ the bay name is linked so a click on the link zooms in to that bay.

You can also use the buttons at the top of the map. Click the Zoom In button at top of map and move cursor over the map to the area of interest. The pointer becomes a cross. Left click at the cursor and drag a box around the area to enlarge. The map will be centered on the box and zoomed to that area. Another technique is to click the Zoom In button at a point on the map. The map generated will center on that point and show approximately 25% of what was shown before. [back to top of page]

Click the Bay Zoom button at the top of the map, move the cursor to the bay of interest on the map and left click. The map will display the selected bay area. [back to top of page]

What do the other buttons do?
Each button has a distinct function within the application. Button explanations are given below. [back to top of page]

Click the Zoom Out button at top of map and move cursor over general area of interest. The pointer becomes a cross. Left click and the mapped area will enlarge by approximately 50%. [back to top of page]

Click the Pan button at top of map and move cursor (which becomes a hand) over general area of interest. Left click on the map and drag in the direction away from the area you want the map to display. [back to top of page]

Click the Show All Bays button at top of map and the map returns to display of the entire Texas coast. [back to top of page]

Select a year from the Year tab. Click the Bay Report button at the top of the map, move cursor to a bay and left click to get the ‘Species Catch Rate Report’ for that bay. This button allows you to click on adjacent bays to get additional information. [back to top of page]

Clicking the Clear Selections button will remove report on the left and/or remove the red, orange and yellow colors on the map.

What does the Graph Catch Rate for This Bay button do?
Clicking this button under the Species Catch Rate Report will open a window showing a line graph of the average catch rate for each species caught in that bay from 1980-2005. The average catch rate was calculated based on the mean number of fish caught per hour using data collected from microfilament gill nets.

There is a point on the graph for each year with data. These points are then connected with a straight line to show how the catch rates changed through the years. [back to top of page]

What does it mean if there is a line, but no point on the graph?
If there is no point, it means no data was collected for that year.

I cannot print reports or they look wrong. What is wrong?
When printing reports, portions of this website may prompt for the installation of a print control component. This component allows users to print data in a printer friendly format. To install the print control, users will need to have administrative rights/privileges on the computer they are using. You will also have to set your printer's page orientation to landscape to avoid cropping off a portion of your report.

How can I export data into other file formats?
When you click on the "Graph Catch Rate for this Bay" button, a graph containing data for the bay you selected is generated. In the upper right-hand portion of the page containing the graph, you will see a drop-down box labeled Select a Format. Click on the downward pointing arrow to the right, click on Acrobat (PDF) file or XML file with report data. Please note exporting to the .csv format does not work at this time. [see below].

What is the best export format if I want to save a copy of the graph?
The best export format for saving an image of the graph is Acrobat (pdf). Exporting the graph as an XML document is the best way to see the data used to generate the graph. [back to top of page]

What is the best export format if I want to export data?
The best export format for exporting data contained in the graph is XML. Save the file as XML, and then open the file in Excel as an XML list. Or you can open a blank spreadsheet in Excel and choose to import your saved XML file using the ‘Import External Data’ command under the Data menu in the main toolbar. [back to top of page]

I tried exporting to the .csv (comma separated value) format and it does not work. Why?
This is a technical issue with the report services used to generate reports in a graph format. Essentially the graph once generated, is an image as opposed to being raw data and therefore cannot be exported to the .csv format. TPWD developers are aware of this issue and are working to correct it. [back to top of page]
