Shrimp and Bycatch Estimates from Trawling in Simoom Sound, 2000-2001

November 2000 and February 2001 data from a study on shrimp trawling and trapping in Simoom Sound, British Columbia, compiled by Meagan Mak. The dataset contains estimates for shrimp, prawns, fish, and bycatch organisms, including details on weight, sex ratios, egg location, and physical damage to specimens. It was collected as part of a project investigating ecosystem modification by fishing gear.

Use Cases

• Analyze bycatch organism estimates to assess the ecological impact of otter-trawling and beam-trawling methods.
• Compare weight and sex ratios of humpback shrimp (Pandalus hypsinotus) across different gear types like trapping and trawling.
• Study the frequency and location of physical damage (e.g., to rostrum, carapace, abdomen) on shrimp specimens to evaluate gear-specific collateral damage.
• Investigate the relationship between shrimp catch estimates and egg location data for population studies.

Strengths

• Data originates from a focused study conducted in November 2000 and February 2001, providing specific temporal snapshots.
• Includes detailed biological metrics such as weight, sex ratios, and physical damage assessments for multiple species.
• Compiled and formatted by a named researcher, Meagan Mak, adding traceability.

Limitations

• The dataset's sample size (number of rows or observations) is unknown, limiting statistical power assessments.
• Spatial coverage is limited to Simoom Sound and a preliminary study in Northumberland Channel, reducing geographic generalizability.
• Data is from 2000-2001 and may not reflect current fishery or ecosystem conditions.
