Fish spawning aggregation (FSA) and passive acoustic monitoring (PAM) research for red hind (Epinephelus guttatus) and other groupers at multi-species sites


How is it funded, who administers it?


Why was the survey originally designed?


What are/were the intended outcomes/objectives?


Show the geographic coverage (including depth) of the survey (maps are helpful)



How often is the survey conducted (annually, biennially, biannually etc)?


Is it seasonal?


Describe the underlying experimental design

Fixed site or stratified-random (If stratified-random, describe the strata)?


Describe allocation of sites per strata (proportional/weighted?) and number of sites.


Describe the methodology and gear

Abundance and size estimates


Passive acoustic record


Describe the outputs of the survey

Describe the data outputs & include a discussion of the variance structure of the data


Self-Evaluation of pros and cons of Survey

What suite of species does this survey target (what are gaps)?


What are the gear/method biases (catchability, size selectivity)?


What are the temporal/spatial limitations?


Is this survey expected to continue into the future?


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


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

Spatial/Temporal coverage


Data generated: length frequency, spawning stock biomass, mortality etc.
