Life History Data for Sharpnose and Blacknose Sharks in the Gulf of Mexico (2010-2011)

Life history data were collected from Atlantic sharpnose and blacknose sharks in the Gulf of Mexico during the Congressional Supplemental Program. The dataset includes measurements such as length, sex, state of maturity, fecundity, and anatomical structures from reproductive tracts. Data collection occurred from October 20, 2010, to October 23, 2011, and the dataset is maintained by NOAA NCEI.

Use Cases

• Analyzing length-at-maturity relationships for Atlantic sharpnose sharks.
• Comparing fecundity and reproductive tract anatomy between shark species.
• Studying sex ratios and maturity states within the sampled shark populations.
• Investigating life history parameters for stock assessment and conservation planning.

Strengths

• Data collection covers a defined one-year period from 2010-10-20 to 2011-10-23.
• Includes detailed biological measurements like fecundity and reproductive tract anatomy.
• Dataset is hosted by NOAA NCEI and appears on multiple government platforms, indicating official provenance.

Limitations

• The exact row count and column names are not provided by any source.
• Sources conflict on the last updated date, reporting both 2011-10-05 and 2026-03-06.
