Field. — Utilization of Dogfish 287 



the vessel equipped with a small rendering plant to operate 

 at sea near the fishing fleet. But we are rather hopeful of a 

 solution from the fact that a fleet of otter-trawlers 

 is developing in Boston harbor. There are at pres- 

 ent four, and at least two more will be launched soon. The 

 question is whether these otter-trawlers, which catch a large 

 quantity of dogfish may not find it profitable to bring them 

 in either entire or in part, e. g., livers, eggs, fins and fail. 

 The otter-trawlers are very much opposed by the general 

 fishermen and vessel owners, who believe that they will de- 

 stroy the fishing grounds, as it is claimed that they have 

 done in the North Sea. If, however, it can be shown that 

 the otter-trawlers can be used for destroying these dogfish 

 and placing them on the market, thus cutting oft" an enor- 

 mous economic loss to the fishermen, possibly there will be a 

 better feeling between the old line fishermen and the otter- 

 trawlers.
