REPORT TITLE: Degradability of Natural Materials Used to Attach Escapement Panels to Blue Crab Traps in Texas

AUTHOR:  Shively, J. Dale

PUBLISH DATE:  February 28, 1997

ABSTRACT

Mortality of blue crabs associated with "ghost" fishing traps in the recreational and commercial fisheries is a problem of increasing concern to fisheries managers, commercial fishermen, and environmental groups.  Degradability (days-to-breaking) of four binding materials (jute, heavy duty cotton, cotton cable, and medium weight cotton) used in the construction of escapement panels and attachment loops for lid tie-down straps in Texas coastal waters were monitored for a 17 month period.   Jute and sisal materials had lower days to breaking than the cotton materials.   Their use is recommended to reduce the effects of ghost fishing by abandoned traps in Texas coastal waters.
