Shrimp and Fish Trawl Transects in Clio Channel Bays (2001-2002)

Epifauna taxa data from trawling transects in Bones Bay and Turnour Bay, British Columbia, compiled by Meagan Mak. The dataset captures observations from replicate beam-trawl and towed video-camera surveys conducted in 2001 and 2002. It documents bottom-dwelling shrimp, fish, and other epifauna before and after trawling activities.

Use Cases

• Analyze epifauna taxa distribution, such as common shrimp and sea whips, between Bones Bay and Turnour Bay video transects.
• Assess potential effects of shrimp trawling gear on benthic habitat by comparing observations before and after trawling.
• Study fish and shrimp population dynamics across the northern and southern portions of Clio Channel.

Strengths

• Data collected via replicate beam-trawl and towed video-camera surveys, providing observational records.
• Covers two distinct geographic areas (Bones Bay and Turnour Bay) within Clio Channel for comparative analysis.
• Temporal coverage is clearly defined for the years 2001 and 2002.

Limitations

• Unknown row count and specific column structure limit precise assessment of dataset scale and variables.
• Sample data and column details are unavailable, hindering immediate understanding of data granularity.
• Data is over 20 years old, which may limit relevance to current marine ecosystem conditions.
