Description
Hundreds of files, ledgers, and log books from a fisheries data archive contain biological, survey, and market data on herring. The collection includes individual fish age, length, weight, maturity, vertebrae counts, and scale projection data. Associated environmental observations and spatial catch distribution information were collected by scientists at ports like Lowestoft and Great Yarmouth.
Use Cases
Modeling herring population age structure based on biological data including age, length, and weight.
Analyzing growth patterns using scale projection data on length-at-age.
Studying historical stock distribution based on spatial information of herring catches.
Investigating environmental correlations using daily weather and wind observations from surveys.
Strengths
Covers a long temporal range from 1905 to 1990.
Includes multiple data types: biological, survey, market, environmental, and spatial.
Data was collected from dedicated research surveys and traditional fishing ports.
