Tllffi STUDY, lanniNG AMD MNDLIMG OPERATiaiS 



In ita nbudy of work practices on shrimp fishing craft First 

 aosoarch Corporation was able to obtain time factors for various fishinj^ 

 and handling operations aboard ship. Time values v/ere recorded separately 

 for operations connected vdth the setting of nets, the drag.-^ing and haul- 

 ing of nets, the handling of trynets, and the handling of shriinp aboard 

 ship. Table III- 8 lists average, fastest, and sloT'est time values record- 

 ed for these operational steps. (See table III - 8, page 139) 



On the average, setting nets took nearly nine minutes; the 

 average drag was slightly over four hours, and hauling the nets toolc from 

 about five to over 32 minutes. 



Trynet operations were less tiiiic -consuming. Swinging out, 

 lowering and setting of trynets took from about 1-1/2 to over 6 minutes, 

 dragging time varied from 9 to 55 minutes, and heaving and dumping of try- 

 nets took from one to 5-1/2 minutes. 



Time consimied in handling shrimp on board depends on the quanti- 

 ty of catch processed. To have any real meaning, time for such operations 

 as heading, dumping trash, cleaning and fto ring of shrimp must be recorded 

 in terms of niufiber of pounds of shrimp handled. The man-hour particulars 

 collected by First Research Goiporation, consequently, are significant 

 only as an indication of the relationship of the time values for tho in- 

 dividual handling operations to each other. 



The variations in tirao required for the same operation by in- 

 dividual vessels are due principally to difference in skill and effort of 

 crew members and cannot be attxabuted to any significant differences in 

 methods employed. Size of vessel and gear have a relatively small in- 

 fluence on the tirno required to perforra vai-ious operations. In general, 

 the sample obsei'vations appeared to indicate that the smaller boats were 

 capable of faster operations than the larger boats* 



Only one vessel used tho trynet with any degree of regularity 

 for the purpose of estimating catche:!; with tho large net. .Since the try- 

 net operation is perforaisd during the trawling cycle and is accomplished 

 by the utilization of othert-jiso idle time, the i<'irst Research Coi'pox-ation 

 analysts were of the opinion that its use appeared higlily desirable from 

 the standpoint of vessel efficiency. 



Concerning tho processing of slirirap aboard ship it was noted 

 that operations consumed little, if any, more time on a freezer vessel 

 than on an iced vessel.
