The hydraulic jet dredge became the main 

 piece of surf clam harvestiiior gear in use today. 



Many modifications have been made or in- 

 corporated into this piece of gear since its in- 

 ception. Today, the hydraulic jet dredge is be- 

 ing successfully operated from stern trawler 

 type of boats. 



This gear has been adapted for use on many 

 different sizes and types of vessels, most of 

 which have been converted from some other 

 type of fishery.
