Gillnetting: History, Types of gillnets & Selectivity
Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line." The line along the bottom of the panels is generally weighted.…

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Gillnetting, one of the stronger structural bridges in this analysis connects Gillnetting with History. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
