A Brief Summary of Early Exploratory and Fishery-Independent Caribbean Surveys Conducted by NMFS Pascagoula

 

How is it funded, who administers it?

  • NMFS Pascagoula

 

Why was the surveys originally designed?

  • To explore possible fishery resources in the US Caribbean.

 

What are/were the intended outcomes/objectives?

 

Describe the temporal and spatial coverage of the survey

Show the geographic coverage of the survey

  • See table and maps below

 

How often is the survey conducted?

  • Annually, but not necessarily during the same season each year.

 

Is it seasonal?

  • No

 

Describe the underlying experimental design

 

Describe the methodology and gear

 

Describe the outputs of the survey

  • The data are digitally available from 1979. Most datasets contain catch and length data with gear type, location, and limited environmental/habitat information.

 

Self-Evaluation of pros and cons of Survey

What suite of species does this survey target?

  • These surveys targeted multiple species. The reef associated surveys have collected red hind, while the deeper surveys collect members of the deep water snapper group.

 

What are the gear/method biases?

  • There are numerous gear and method biases, due to the fact that each survey has its own specific objectives (see table).

 

What are the temporal/spatial limitations?

  • Due to the fact that each survey has its own specific objectives (see table), there is no consistent temporal/spatial sampling over the time series. Also, in all surveys listed below the density of sampling effort is low compared to the area of the US Caribbean.

 

Is this survey expected to continue into the future?

  • No

 

It is relatively expensive/inexpensive, logistically difficult/easy?

  • It is expensive and logistically difficult to conduct NOAA “white boat” surveys.

 

Self-Evaluation of utility of survey for generating information for stock assessment

Spatial/Temporal coverage

  • These data are of limited utility, due to the lack of consistent temporal/spatial sampling over the time series.

 

Data generated

  • CPUE data are of very limited utility, and length data may be of some utility for certain species.
