NOAA's National Oceanic and Atmospheric Administration provides reproductive data for Squalus cubensis, the Cuban dogfish shark. The dataset was opportunistically collected over an eight-year period from 2005 to 2012 in the Gulf of Mexico. It contains measurements necessary for analyzing the species' reproductive biology.
Use Cases
- Examining reproductive cycle timing and duration using recorded collection dates and maturity states.
- Estimating fecundity by analyzing counts of embryos or eggs per female.
- Determining size at maturity by correlating individual length measurements with reproductive status.
- Calculating gestation period through analysis of developmental stages recorded over the time series.
- Modeling population dynamics in the Gulf of Mexico using baseline reproductive parameters.
Strengths
- Data collection spans an eight-year period from 2005 to 2012, providing a multi-year time series.
- The dataset is curated and published by the authoritative National Oceanic and Atmospheric Administration (NOAA).
- Its presence on multiple federal data platforms (Data.gov and NASA Earthdata) indicates formal review and archival.
Limitations
- Specific column names, row counts, and file formats are not provided in any source description.
- The 'opportunistic' collection method may introduce sampling bias not detailed in the metadata.
- There is a conflict in the 'last updated' date: Data.gov lists 2026-03-05, while NASA Earthdata lists 2012-12-03.
