As the net is nov/ clear for hauling, the cables are brought in 

 with the winch until the two doors ai'o blocked at the outri^^ce^^* 'i'he 

 vessel is generally stopped during this procedure, but occasionally some 

 way is maintained to perirdt limited maneuverability. The net is hauled 

 to windward of the vessel, 



lihen the doors are up, the lazy line ixihich is secured around 

 the mouth of the bag of the net is led through the block of the running 

 whip which is then hoisted to the boom's end. The lazy line is then led 

 to the winch and is heaved in until the neck of the bag is above the bul- 

 wark rail. The block and fall at the end of the boom is then secured 

 around the neck of the bag with gripe or sling. The bitter end of this 

 tackle is then led to the irinch and the bag of the net is raised out of 

 the \jater and brought aboard and held suspended over the deck. One man 

 can steady the net with a preventer while a second releases the slip- ' 

 knotted tie rope securing the end of the bag. This dumps the catch on 

 deck. During this operation, the vessel is stopped and the captain comes 

 aft to assist the crew. 



After the net is dumped and cleared of larger, trash fish, the 

 vessel is gotten underway, the net is streamed, and the fishing operation 

 is repeated. 



After the last haul for the trip, the net is cleared of trash 

 as far as possible by hand. It is then streamed and towed at top speed 

 for a period of three to five minutes. The vessel is again stopped and 

 the net is taken on board, using the winch and whip line. The whip line 

 is then used to bring the doors on board and the doors are secured as 

 before. The vessel novr is ready to anchor or proceed to port, 



1/hile the shrimp travrl gear is operated essentially in the same 

 manner by the inshore and offshore fleets, there are differences between 

 the fleets in methods of locating shrimp. Use of the trynet for locating 

 shrimp is not as X'fidespread among inshore vessels as among offshore ves- 

 sels. 



Three general types of fishing methods appear to be prevalent. 

 In the first, the fisherman uses only the main trawl to locate shrinj). 

 The length of drag is a matter of choice of the fisherman, but generally 

 the trawl is fished for one-half hour to tiro hours for each haul. If the 

 catch is sufficient, the trawl is again put over; otherwise, a new area 

 is sought and the procedure repeated. The second method, still being em- 

 ployed in shallow water areas in Louisiana involves the use of a cast net 

 thrown ahead of the boat as it moves slowly over the flats. I'ihen shrimp 

 are taken in the cast net, the trawl is put out. As the trawling proceeds, 

 the cast net is continually throvm ahead of the boat. If the boat passes 

 into an area where shrimp can no longer be taken in the cast net, the boat 

 is swung around to again cover the area where shrimp were found. The 

 third, and most efficient method for locating shrimp, involves the use of 

 the trynet before the large trawl is put into operation.
