Bullimore et al.: Study of catches in a fleet of "ghost-fishing" pots 
253 
fishermen to use these conservation measures in conjunc- 
tion with the traps, with the exception of bylaws in two 
areas (Table 3). Conservation measures such as these are 
relatively inexpensive to introduce and would greatly re- 
duce losses from the fishery of commercially important 
species, such as lobster and brown crab, as well as species 
of conservation interest such as ballan wrasse. 
Acknowledgments 
The authors gratefully acknowledge the help of David 
Bray, a local professional fisherman, and the South Wales 
Seafisheries Committee for the loan of pots. The input of 
several referees has greatly improved previous versions of 
this manuscript. This study was funded in part by Euro- 
pean Commission study contract 94/076.
