Beaufort Sea Marine Fish Measurements and Biological Data 2013

48 fish species were caught during the 2013 Beaufort Sea Marine Fishes Project survey. This dataset contains biological measurements including weight, multiple length types, liver weight, gonad weight, sex, and maturity for each specimen. The survey was conducted by Fisheries and Oceans Canada using benthic trawls at 53 stations across 8 transects.

Use Cases

• Analyze species distribution and abundance using family and species identification across 53 sampling stations.
• Model relationships between total length, fork length, standard length, and weight for different fish families.
• Investigate reproductive biology by examining gonad weight and maturity level in relation to species and sex.
• Calculate condition indices by comparing liver weight to total body weight across different species.

Strengths

• Data originates from the first large research trawl survey of offshore marine fishes in the Canadian Beaufort Sea.
• Includes detailed biological measurements for 48 distinct fish species caught.
• Sampling followed a standardized protocol using benthic trawling nets at 53 predefined stations.

Limitations

• Dataset is limited to a single survey period from August to September 2013, lacking temporal comparison.
• The sample size (number of individual fish rows) is not specified in the provided information.
• Geographic scope is restricted to the southern Canadian Beaufort Sea and Amundsen Gulf.
