About the Database

The fish species for which literature references have been assembled in the database are: Atlantic sturgeon, Acipenser oxyrhynchus; shortnose sturgeon, A. brevirostrum; American shad, Alosa sapidissima; alewife, A. pseudoharengus; blueback herring, A. aestivalis; bay anchovy, Anchoa mitchilli; bluefish, Pomatomus saltatrix; Atlantic tomcod, Microgadus tomcod; striped bass, Morone saxatilis; white perch, M. americana; and largemouth bass, Micropterus salmoides. The references in the database mostly represent published papers and unpublished reports. The database is organized to allow searches for selected information.

Database Accession/Installation

All references in the database have been listed as a simple bibliography in a paper publication, "Habitat Use and Requirements of Important Fish Species Inhabiting the Hudson River Estuary: Availability of Information," issued as NOAA Technical Memorandum NMFS-NE-121. To search the database for selected information, one of three options must be exercised. First, internet users can access the database at "http://www.nefsc.noaa.gov/nefsc/habitat/hudson." Second, the paper publication will soon be copublished as an electronic publication accessible at "http://www.nefsc.noaa.gov/nefsc/publications". There will be a "hot link" within the electronic publication which will open the database. Third, for those without internet access, two 3.5-inch disks can be obtained free of charge and upon request from the Northeast Fisheries Science Center's Editorial Office (166 Water St., Woods Hole, MA 02543-1026). Instructions accompanying the disks permit the user to install and run the database in a Windows environment.

Database Navigation and Operation

IMPORTANT: Do not add to, delete from, or alter the database. Records have been entered in a specific way to allow proper output for the bibliographic format. Changing the information in any field of any record will interfere with the program's ability to write the correct bibliographic output.

The database will open to the "Introduction" screen. Use the arrows on the right-hand side of this and other screens in the database to scroll up and down within those screens. The "Introduction" screen lists five options for where to go within the database. (Returning to the "Introduction" screen is possible at any point in the database search by clicking the appropriate button in the top right-hand corner of the screen.) The five options are:

1. About this database: Clicking on this button produces a screen explaining the history and purpose of this database.

2. For help: Clicking on this button produces the help screen, which contains much of the same information as this user's guide.

3. To go to the main view of the database: Clicking on this button produces a screen showing the first record in the database, with all information which has been entered for that record. Use the arrows on the right-hand side of the screen to scroll up and down within that record. Click on the lower "card" on the picture of the "rolodex" in the upper left-hand corner of the screen to move to the next record; click on the upper card to move to the previous record. To move farther ahead or back than one record at a time, place the arrow on the "tab" which sticks out to the right of the rolodex, click and hold, using the mouse to move it up and down alongside of the rolodex. The number immediately below the rolodex will indicate the current record being accessed. The records are listed alphabetically by author.
At the top of this screen are three options:

a. To go back to the introduction screen...: Click the button to go back.

b. To show list of all records...: Click the button to get back to the full list of records after performing a search.

c. To view records in bibliographic format...: Click the button to change from the main view, which shows all information in the records, to the view which only displays the records in bibliographic format. Note that at the bottom of each page in bibliographic format, there are instructions on whom to contact (i.e., John Boreman) should the user need additional information. The affiliation and e-mail address of the contact have changed, however, since the database was prepared. The new affiliation is Northeast Fisheries Science Center, 166 Water St., Woods Hole, MA 02543-1026; the new e-mail address is John.Boreman@noaa.gov.

The main view contains all possible items (also known as "fields") that may exist for any of the records. The fields are listed in Table 1.

4. To perform a simple search on single items: This option allows searches one item at a time. If you need to search on more than one item at a time, then use the multiple-item search option. Clicking on the button for the simple search option produces a screen which displays three options:

a. To perform a simple search on a fish species...: Click on this button to produce a screen showing a list of the 11 species which are the focus of the database. Choose the species, then click the "find" button, to show all records with information on that species.

b. To perform a simple search on a keyword...: Click on this button to produce a screen showing a box labeled "keyword." A pulldown menu in this box allows selection of a commonly-used keyword, such as "larva." Choosing "other" from the menu allows the user to type in a keyword. Click the "find" button to perform the search. The keywords used most often in the database are listed in Table 2.

c. To perform a simple search on an author...: Click on this button to produce a screen showing a box labeled "author." Click on the box, type the last name of the author to be located, then click the "find" button.

Remember, returning to the "Introduction" screen is possible at any point during the search by clicking the button in the top right-hand corner of the screen.

5. To perform more complex multiple-item searches: This option allows searches on more than one item at a time. Click on this button to produce a screen displaying instructions for two, different, multiple-search options: an "and" search, and an "or" search.


The "and" search finds only records where all criteria are met. For example, to search for a paper which discusses bluefish larvae, the "and" search will only find records with both "bluefish" and "larva" in the same record. Enter criteria in the appropriate boxes. For example, to enter a fish species in the "Fish Species" field, place the arrow on the box, click, and hold. This action reveals a pre-set list of choices. While still holding, drag the mouse down until a choice is highlighted, then release. The same may be done in the "Keywords" field. If searching other fields, such as "Author(s)," simply click the mouse to the right of the field name. A box will appear within which a choice can be entered. After criteria have been entered, click the "find" button to run the search.
The "or" search finds records where any of several criteria are met. For example, to search on all papers which discuss bluefish or striped bass, the "or" search will find all records with either "bluefish" or "striped bass" in the record. Enter one of the criteria in the appropriate box, then click the "new criteria" box. Enter the next independent criterion, and repeat these steps until each criterion has been entered, then click the "find" button to run the search.
