52449 All Data in .xls File With Tabs Entity Published / External 8548 Red Porgy Reproductive Analysis Data Set Completed Protogynous fishes are often assumed to be more sensitive than gonochorists to exploitation, primarily because of potential sperm limitation and/or social disruption of mating if larger, mostly male individuals are selected for. Overall goals of this research were to study the reproductive ecology of the red porgy Pagrus pagrus (Sparidae) in the NE Gulf of Mexico to learn how fishing might affect this and other protogynous species; and to examine the temporal, bathymetric, and small scale (10's of kilometers) spatial variability of its life history traits and demographics to gain insight on population structure and shed light on the apparent sensitivity to exploitation of the stock(s) in the U.S. South Atlantic Bight (SAB). TABS are included with this in which calculations and graphs were done based upon the data. The first tab has the same data as redporgy_study.csv An early objective was to determine if the behaviorally-related size and/or sex selectivity observed in other protogynous species occurred in red porgy, i.e., were larger individuals or males at a site more aggressive and more likely to bite a hook before smaller ones or females?

Tabs are included with this in which there are calculations and maps 5 Full Data Set TAB No No Active This is the Tab for the Data Set Data: All other tabs are from analysis/calculations from this tab 10 Collection_Number Number 7 No No Active Collection Number. First 4 digits are the year. Collections numbered sequentially by date and started over at 001 each year. 20 Fish_Number Number 3 No No Active Fish Number.
