Length-frequency distributions, expressed as proportions, by bridle length. Thin solid lines represent 
short bridles, medium solid lines represent standard bridles, and thick solid lines represent long bridles. 
consistent with the observed changes in bridle efficiency 
with fish length. All five species with length-independent 
herding efficiency displayed no change in mean length. 
whereas both species with herding efficiency that declined 
with fish length displayed a decline in mean length with 
increasing bridle length (Tables 2 and 3).
