Title: TIP in the US Caribbean-Puerto Rico and the U.S. Virgin Islands
Short Name: TIP Caribbean - Puerto Rico and USVI
Status: In Work

The Trip Interview Program (TIP) has been used to collect length-frequency data as well as catch-effort data from the US Caribbean since 1989. Data collection by the agencies in Puerto Rico and the USVI existed prior to 1989; however these were not collected under TIP guidelines. TIP data are currently collected and entered through a web-based application (TIPONLINE) into an Oracle database in the Miami Lab-SEFSC where they are accessible by fisheries assessment biologists to be used in the management of commercial fisheries in that area. Programs in Caribbean vary slightly from those on mainland, therefore they are treated separately.


To collect length-frequency data as well as catch-effort data from the US Caribbean for use in fisheries stock assessment.


In 2004 an on-line data entry system (TIPONLINE) became available; however, it was not until much later, circa 2011, that the on-line system came into use by the agencies in the US Caribbbean. This was due to the lack of high speed internet services there. Prior to that data were entered on PC and batch processed.

There is no 2 ticket system for landings data in the US Caribbean. Fishing data are logged on catch forms by the fishers. TIP data can be used to enhance catch data when reports can be matched up.

Procedure Information

Procedure Type: Intercept Survey

Procedure Steps

Step 1: 1

Step Name: Identify Landing Sites

The port agent identifies all locations where the fish are landed (brought across the dock).


Random coverage of all landing areas.

Step 2: 2

Step Name: Identify fishers

Select fishers from their catch report submissions and a valid permit list. Communicate with fishers in all locations to determine which fishers are willing to cooperate. Assign numbers to these. Randomly select fishers/locations for interview.


Determine the active fishers and try to ensure cooperation. Randomly select from these and their locations.

Step 3: 3

Step Name: Intercept Trip

Randomly choose location and fishers. Arrive at landing location (try to arrive in time to encounter trip before off-loading begins).


Random selection within the cooperative permit holders will help to ensure good coverage of the fisheries. Important to sample all catch from trip, not just part.

Step 4: 4

Step Name: Interview Fishers

Interview the permit holder selected. Collect information on target species (or species group), gear used, locations fished, days/hours fished.


To qualify the sample according to fishery type, location, and time frame

Step 5: 5

Step Name: Identify catch

Separate the fish according to species or species group. Identify these accordingly. Quantify (by weight and numbers) catch of each grouping.


To determine catch composition and enable sampling throughout the catch.

Step 6: 6

Step Name: Sample individual fish

Select all of a group up to 30 individuals. Identify according to species. Take individual lengths. Repeat for each group. Record data.


To obtain random length-frequency data which can be expanded using reported landings or number of trips on a weighted basis by fisher or vessel.

Step 7: 7

Step Name: Record Data

Record all sample data collected on sampling sheets.


Record data for entry to electronic format

Step 8: 8

Step Name: Enter Data

Enter the data into electronic format using SEFSC data entry system.


Data entered to be used for analysis by fishery managers

Access Information

Security Class: Sensitive
Security Classification System:

Password Restricted. Rule of 3: Data summaries must include at least 3 dealers to be considered non-sensitive. See:

NOAA FORM 58-5 (1-84) TRANSMITTAL 127,

National Oceanic and Atmospheric Administration

NOAA Administrative Order 216-100


Date of Issuance: July 26, 1994

Security Handling Description:

Sensitive data may only be released to entities having a signed non-disclosure agreement on file with the Director of the Information Resources Management Division (IRMD). Otherwise, sensitivity may be suppressed by the following methods used for aggregation of sensitive data:

Data that are submitted as sensitive can be released to the public under the following circumstances:

1. Combined or aggregated data. Sensitive data can be released if the data are aggregated or summarized in a manner that prevents the identification of the person or organization that submitted the data. The "rule of three" and identification of majority allocations" are the primary data suppression methods.

2. Obscure (scramble) or remove the data identifier. For some types of data, sensitive data Can be released as non-sensitive if the identity of the person, vessel, company, etc. that submitted the data is not included or is scrambled as part of the data that are released.

3. Submitter. Sensitive data collected under federal authority Can be released to the original entity (person, vessel, business, etc.) that submitted the data.

4. Sensitive data waived. The protection of sensitive data can be waived by the person or business that submitted the data.

Data Access Policy:

See NOAA Administrative Order 216-100


Date of Issuance: July 26, 1994

Data Access Procedure:

These standards and procedures apply to all employees of the SEFSC that need access to sensitive fisheries statistics. This includes full time or term employees, contractors, volunteers, and/or other employees associated with the SEFSC, but not directly employed by either organization. Any SEFSC employee that needs or desires access to sensitive data must have read NOA 216-100 and submitted a signed nondisclosure statement to the Director, Information Resources Management Division (IRMD). The non-disclosure statement must be approved by the Director of IRMD and maintained on file by IRMD. It is the responsibility of the Director of IRMD to certifY upon request, that a person or organization that requests access to sensitive data is authorized access to those data. All employees that have access to and/or use sensitive data (federal and non-federal) are responsible to protect those data from unauthorized access or release. Contractors or grantees that have an agreement with NMFS can be granted

access to sensitive data as an authorized user (See NOA 216-100 1 Section 6.03e). It should be clearly understood that sensitive data cannot be released simply by an individual signing a nondisclosure statement. There must be a clear and demonstrable need for the sensitive data that are requested as part of a contract or grant. Sensitive data can only be released for the specific contract or grant. Upon completion of the contract or grant, the recipient must either return the data or state that it has been destroyed. The contractor or grantee cannot use the data for any purpose other than the uses stated in the agreement. The Contracting Officers Technical Representative (COTR) or the Technical Monitor (TM) that has been assigned to the contract or grant, respectively, has the following? responsibilities:

1. The COTR/TM has the responsibility to determine whether the contractor/grantee is eligible to receive the sensitive data that are requested in the agreement.

2. The COTR/TM has the responsibility to assure that all persons included in the agreement have read NOA 2l6-l00 and have signed a nondisclosure statement. A statement must be signed by each person that will have access to the sensitive data under the agreement, i.e., a blanket statement cannot be used for the company or firm. The COTR/TM also has the responsibility to make sure that the Director, IRMD has signed and approved the nondisclosure statement and the statement is on file with IRMD.

3. The COTR/TM has the responsibility to assure that sensitive data are not released in any publication, report, oral presentation, or other means to the public by the contractor or grantee.

Issue 1

CC ID: 345161
Author: Bennett, Joshua

Puerto Rico does not enter data into the TIP landings or sample sections. They enter only interview, effort, and individual sample data.

Issue 2

CC ID: 345162
Author: Bennett, Joshua

These data are raw data. They represent catch from individual trips and have not been adjusted (weighted by landings) to represent overall commercial catch.

Technical Environment


Oracle database SECPR, TIPONLINE schema. TIPONLINE data entry application

Data Quality


These are raw data and represent the individual trip sampled. No expansion has been done. Only interviews for complete landings represent the entire trip.


Accurate to the mm in almost all cases.

Analytical Accuracy:

To the millimeter

Quantitation Limits:

Lengths are center-line in mm.


Biases exist as only cooperative fishers are sampled. Interviews for incomplete landings may not represent actual catch for species listed. Fish discarded or not targeted due to size considerations (such as larger fish suspected of containing Ciguatera) are not included.


Landings (logbook) data may not match up with TIP according to species or species group due to landings being reported by the fishers who may not include all species of catch. As mentioned before some TIP samples are from incomplete landings. Also in USVI only landings of sold fish are perhaps being reported.

Completeness Measure:

Not all records are included in analysis. Records having questionable lengths and/or weights, or atypical length/weight ratios for a species may not be included at the analyst's discretion.


To grams and millimeters

Detection Limit:

Millimeters and grams are the lowest limits

Completeness Report:

Many samples of incomplete landings exist in TIP for the US Caribbean. More valuable species may be targeted in some cases at the expense of minor species. Very little data for conch available in TIP although it is a major species. Many dive trips show conch landings which are not reflected in TIP.

Conceptual Consistency:

Not measured; however, realities of fieldwork may and do interfere with the concept of random sampling of complete trips.

Quality Control Procedures Employed:

Port agents are trained in species identification. Fishing centers, species, gear codes must appear in lookup tables. Visual proofing is under control of the submitting agencies. Maximum sizes and length weight regression are used to flag questionable data after load to SEFSC database.
